The document discusses roll pass design for continuous bar mills. It defines basic terminology like roll pass and nominal roll gap. The goal of roll pass design is to produce the desired product shape with good internal structure, surface and lowest cost. There are definite, intermediate and combination pass shapes. A deformation changes one shape to another, while a sequence produces a definite shape. Roll pass design considers the starting material, mill layout, sizes, power and production needs to determine pass details, schedules and power requirements for each pass. It also discusses basic rolling laws and formulas for shapes like squares and ovals.
I have tried to explain some very important but basic definitions related to Roll Pass Design. I am very grateful to my mentor, my friend Mr. Mark J. Schwietzer, without whose help it was not possible for me to make this presentation, thank you Mark :)

End splitting during long products rolling billet quality of rolling processJorge Madias
End splitting occurs because the material being rolled has not enough ductility to withstand the stress to which it is submitted. This may happens for different reasons. Coarse cracks in the billet end, like central or diagonal cracks, weakens the end, particularly when the plane where are located coincides in part with the symmetry plane between rolls. Hot ductility of steel depends on the one hand of their intrinsic features, and on the other hand, on the temperature at which they suffer the stress, and its speed.
It is important to roll the steel within the range of higher ductility at a given deformation speed. This is more critical for steels with inherent low ductility as those containing high sulfur.
The role of MnS stringers is also clear; having S controlled at the lower level of the specification is favorable. Nevertheless it is worth to mention that if caster condition is proper and excessive thermal/mechanical stresses do not arise, very high Mn/S ratio is not necessary.
Bar ends loss temperature faster. Another factor is roll cooling, it has to be correctly oriented, not excessive and keeping the position along the processing time.
In other factors experimental and modeling results are apparently controversial. There is coincidence in the fact that more friction between bar and rolls promotes splitting, but not in factors like roll diameter and reduction.
On the basis of pilot rolling results, plane, box-box, square to round and oval to round passes are favorable to avoid splitting, while oval to square promotes splitting.

Steel Making and Rolling (Metalworking): Process & Applications, Rod and Bar...Ajjay Kumar Gupta
The steel industry has taken note of the continued growth in steel imports and a number of projects have been planned and are under implementation.In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Rolling of steel is one of the most important manufacturing processes for steel. It is usually the first step in the processing of steel after it is made and cast either in Ingot or continuous cast product in a steel melting shop.

The gears are a type of mechanical element whose teeth are cut around a cylindrical or conical surface with the same space. It is used for the rotation and transmission of force from the drive shaft to the driven shaft when coupling a pair of elements. The gears can be classified into spiral, cycloid and trochoidal gears according to their shape. It can also be classified as parallel shaft gear, transverse shaft gear and non-parallel and non-transverse shaft gear depending on the position of the shaft.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

‘pass’.. The distance between the barrels of two rolls is
called the ‘nominal roll gap’, or ‘theoretical roll gap’.
•The ultimate goal of a roll pass design is to ensure the
production of the desired shape of a product with the
appropriate internal structure, defect free surface and
at lowest cost
3. The basic five different cross-section
shapes used in roll pass design.
4. Passes & Bars
•Definite passes – those
having two equal axes in
an x, y plane (Squares,
Rounds)
•Intermediate passes –
those having one axis
larger than the other one
(Rectangles – box,
Diamonds, Ovals)
5. Deformation & Sequence
•A definite bar into one
intermediate pass, or an
intermediate bar into one
definite pass configures a
‘deformation’. For example,
a square into an oval pass,
or an oval into a square
pass. A deformation can
produce any type of bar
•A definite bar into two
passes (an intermediate
pass followed by a definite
pass, configures a
‘sequence’. A sequence
only produces a definite bar.
6. The roll pass design for any product depends
on the following:
• Starting size and Material Grade.
• Mill layout.
• Mill stand sizes.
• Mill motor power.
• Production Requirement.
• Product size and shape.
7. Typically a pass design calculation has three
parts:
• Pass design and groove details
• Pass schedules.
• Power calculation.
8. Pass Design and Groove Details: This calculation
gives the following parameters for each pass:
Roll groove dimensions.
Roll gap.
Filled width in pass.
Filled area.
Area reduction.
Bite angle.
9. Pass Schedules: Pass schedule consists of the
following for each pass:
Bar length
Rolling speed
Rolling time
Idle time
Loop or tension value between stands
10. Power Calculation :Power Calculation works out
for each pass:
Bar Temperature
Rolling load
Rolling torque
Rolling power
11. Throughout the mill
•Continuous rolling process -
the long axis of the bar is
brought between the rolls
and is rolled into a shape
with equal axes, then this
shape is rolled into a
different shape with different
axes, and so on. The
reduction must be applied
after a 90-degree rotation of
the bar at each stand.
12. Throughout the mill
•Traditional mills only use
horizontal stands. The ovals
are twisted to bring the long
axis between the rolls.
•To be precise, there is one
deformation that needs special
treatment: the square-into-
oval. It needs rotating the
square by 45°, which can be
obtained (if we don't want to
use twister guides) with a slight
axial displacement of one roll
in the stand that produces the
square.
13. The Mills
•Structures and schematizations
•Continuous bar mill (CBM)
structure consists of a number of
independent stands. 'Independent'
means that each stand has its own
motor (and kinematic chain),
whose rotational speed can be
freely altered. If you don't want the
bar to be twisted you use the HV
mill configuration (with definite
passes in vertical stands).
•From the roll pass design point of
view, a CBM can be schematized
as a succession of passes
centered on the z-axis (when x,y is
the plane containing the roll axes).

15. Laws of Rolling
•First Law
The purpose of the rolling process is to start from a
relatively short bar with a large section area, aiming to
obtain a very long product with a small section area.
Then, the first law to remember is that the volume (or
the weight) is a constant: from a 1/2-ton billet you
will obtain a 1/2-ton coil. Cross sectional area times
bar length is a constant (this is not strictly true for
CBMs: some weight will be lost with scale and crop
ends; but we can afford to neglect that loss.)
16. Laws of Rolling
•Second Law
There is another, important law to remember: the flow is
also a constant. Say that the exit bar from stand 1
has cross sectional area = 3467 sq mm and the
finished round has cross-sectional area = 113 sq mm
(hot bar dimensions). If the finished stand delivers at a
speed of 12 mps, then stand 1 must 'run' at 0.39 mps:
0.3 x 3467 = 12 x 113. In this case the constant is
about 1050, i.e., if you know the areas, you can
immediately calculate the exit speeds. And, you have
no problems in setting the speed at each stand, as
each stand has its own independent motor.
17. Action & Reactions
•When rolling, we can identify one action and two
reactions.
If we focus on a horizontal stand of a continuous mill for
rounds, we see:
- that the rolls apply a 'reduction' (vertically);
- that this reduction produces a wanted 'elongation';
- that reduction produces a 'spread' (sideways).
18. Spread
•When the steel is compressed in the rolls it will obviously
move in the direction of least resistance, so usually there is
not only longitudinal flow but also some lateral flow. This is
called ‘Spread”. it is generally accepted that beyond a ratio
width/height = 5, spread becomes negligible.
Δb=1.15 XΔh (√R X Δh- Δh )
2ho 2f
Δh – the absolute draught in the pass
ho – stock thickness before the pass
R – roll radius;
f– coefficient of friction
The coefficient of Spread, Beta is the ratio between exit
and entry width and is normally > 1
19. Reduction and Elongation
1.Reduction (with a coefficient of reduction Gamma)
2.Elongation (with a coefficient of elongation
Lambda).
•Gamma (defined as ratio between exit and entry height) is
always < 1. If we reduce a 100x10 flat to 8 mm (a 20%
reduction), Gamma=0.8.
•Lambda (defined as ratio between exit and entry length, but
more often as ratio between entry and exit section area) is
always > 1. In the example above (100x10 reduced to 100x8)
Lambda = 1000/800 = 1.25. Note that Beta = 1. (100/100 =1)

rolls and adjusting roll pass for Box

22. Important Formulae
•Square Dimensions
A 90° square with sides and corner radius r has area:
A=s^2-0.86*r^2 (1)
and actual 'reduced' diagonal:
d=s*√ (2)-0.83*r (2)
Note: Square grooves generally have facing angles alpha = 90°
only for larger squares. Generally, facing angle alpha is taken as
90° for s > 45 mm, 91° down to 25 mm and 92° for s <= 25 mm.
In these cases the actual reduced diagonal has length:
d=s/sin(alpha/2)+2*r*(1-1/(sin(alpha/2)) (3)
24. Important Formulae
•Oval Radius
•An oval pass is made of two circular arcs with facing
concavities. Three dimensions are considered, referring
either to pass or to bar:
i. b1t = theoretical oval width (pass, not physically
measurable)
ii. b1r = actual oval width (bar, physically measurable)
iii. maxw = maximum oval width (pass, physically
measurable)
25. Important Formulae
•Oval Radius
To identify oval height, we only need two dimensions:
i. h1t = theoretical oval height (pass, physically measurable)
ii. h1r = actual oval height (bar, physically measurable)
To draw the oval groove we need to know its radius R. The
formula is:
R=(b1t^2+h1t^2)/(4*h1t) (4)
Now, when gap=0 we have b1t=maxw. This means that if the
oval is identified as maxw x h1t, we can put H=h1t-gap and
calculate
R=(maxw^2+H^2)/(4*H) (5)
