“Even
the best can be bettered.” It perfectly applies
to Continuous casting. Industry leaders always work on this concept of “there is a better way” and don’t settle for less. One of the
thought processes is how to get more from the investments on continuous casters
by optimization of the operations. This thought process is vital in the current tough
market conditions. Evolution of manufacturing processes through perfect application
of technology provides the
right platform to optimized manufacturing operations.

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!
UiPath Test Automation using UiPath Test Suite series, part 4DianaGray10

Casting Steel Rolls
High Chromium Steel Rolls - HCrS
The hardness of HCrS rolls is as high as
65-80 HSC. Its matrix gives itself excellent
wear resistance and good fire-crack
resistance.
HCrS rolls have a low carbon content range
of about 10%. An important characteristic of
HCrS is that the mill is not required to adjust
special water cooling conditions. And in the rolling process these rolls can form oxide film to
improve surface quality of rolled products.
These rolls are suitable for both two-Hi roughing and early stand of four-Hi finishing for hot
strip mills.

High Speed Steel Rolls – HSS
HSS rolls have high hardness and good wear
resistance at high temperature. These rolls
are manufactured by Centrifugal Casting (CC)
method and the roll core is filled with
spheroidal graphite cast iron. The adequate
chemical composition control and proper heat
treatment ensures the hardness of roll
working layer to reach as high as 80-85HSC.
Uniformly distributed complex carbides of Vanadium. Tungsten, Niobium and Molybdenum in
the martensitic matrix ensures uniform hardness of working layer and uniform wear out in the
roll passes. These types of rolls are used for finishing stands to increase productivity and
improve surface quality of rolled piece.

Alloy Indefinite Chilled Cast Iron Rolls - AIC
Alloy Indefinite Chilled Cast Iron Rolls is a
cast iron with fine intercrystalline graphite
evenly distributed throughout the working
layer of roll barrel. The sizes shapes and
distributions of graphite and carbide are
controlled by the chilling effect and the
contents of alloy elements. The addition of
alloy elements such as Manganese, Nickel,
Chromium, and Molybdenum changes the
matrix microstructure from pearlite, bainite to martensite. The present of small amount of fine
graphite enhances the roll’s resistance to spalling, thermal crack and wearability. This roll has
small hardness gradient in the working layer of roll barrel and is suitable to medium and
finishing stands for bar, wire and section mills.

Non Continuous Carbides Rolls - NCC
Rolls for roughers require a combination of
some properties, some of which can be
counteracted by the others. These properties
include wearability, resistance of fire cracking
and impact, hot hardness and hot strength etc.
Excessive network carbides will improve
wearability and impact resistance but
dramatically reduce fracture toughness. Under rough rolling process they can promote fire
cracking formation and added to form Bainitic / Martensitic (acicular) matrix, which is more
wearable than conventional pearlitic matrix. The Molybdenum can also improve the hot
hardness of rolls.
This type of roll is manufactured from high alloy materials with special heat treatment. Carbide
content is the matrix is less than 5%, which is satisfactory to the requirement of roughers.

Forged Steel Rolls
Cold Rolling Mill Work Roll
Anti-rolling Mark Roll
In rolling sheets for automobiles and
household electrical appliances, the dent
imperfection brought by the foreign
objects on the roll's surface will most
probably be passed on to the strip surface
to cause color difference and pit in the
rolled product. Due to the demanding
surface soundness of those products,
these kinds of flaws will definitely bring a
negative effect on the strip quality.
Sinom Roll has upgraded their rolls' anti-press-in and anti-scratches capabilities by
adjusting the rolls' alloy composition and heat treatment techniques. The barrel's
hardness can reach over HRC64. Granted as National Patent, this tech can satisfy
the requirement of high-performance cold rolled products such as sheets for
automobile and high-class household electrical appliances.
Material Feature Application
CBRWR-AMR Anti-press-in, anti-scratches
To roll sheets for automobile, high-class household
electrical appliances
High-abrasion-resistance Roll
With the development of current rolling
skill, increases are being achieved
continuously in the products' level and
output. In rolling some steel sheets with
higher strength, phenomenon as
"slippery" will often occur resulting from
excessively fast decreasing of toughness.
As a result, the quality of sheet will
degrade while roll change frequency will
increase. It not only affects the output but also raises the roll's consumption.
By scientific alignment to the chemical composition and rational production
techniques, Sinom Roll optimizes the carbide type and distribution and develops a
series of anti-abrasion rolls.
This product has applied for national patent.

grinding even lead to the spalling.
By adjusting the roll composition,
Changzhou roll adopts special heat treatment to control the grain size of the
hardened layer, the remnant austenite and the hardness of roll in improving the basic
