Introduction to steel Casting and rolling mills

1. INTRODUCTION
TO STEEL
CASTING AND
REROLLING
MILL
• Steel casting
• The steel casting process involves pouring molten
steel into a mold to create a specific shape or form
• Two main types of steel casting: sand casting and
investment casting

2. STEEL
CASTING
• The steel casting process involves
pouring molten steel into a mold to
create a specific shape or form
• Two main types of steel casting: sand
casting and investment casting
• The equipment required includes
furnaces, ladles, tundishes, and molds

3. REROLLI
NG MILL
The solidified billets are then reheated to a
specific temperature in a reheating furnace.
This heating process makes the steel more
malleable and prepares it for the rerolling
operation.
The reheated billets or blooms are passed
through a series of rolling mills, including
roughing, intermediate, and finishing mills
The cross-sectional area of the steel and
shape it into the desired form, such as sheets,
rods, bars, or structural sections.

4. PHASE DIAGRAM
• Phase diagram is a graphical representation of the physical
states of a substance under different conditions of temperature
and pressure.
• The diagram is divided into three areas, which represent
the solid, liquid, and gaseous states of the substance
• It indicate at which temperature/pressure solution changes its
phase

5. PHASE DIAGRAM
• The phase diagram of water is a
representation of the various
pressure and temperature
combinations that create each phase
• The three phases are solid, liquid
and gas.
• Phase diagrams are essential tools in
materials science and engineering as
they provide critical information about
the behavior of materials under different
temperature, pressure, and composition
conditions.
