1

Continuous casting casting process

molten steel
ladle
tundish
mould
secondary cooling
roll layout flame cut off

2

What does a tundish do

Promotte inclusion flotation by maximising residence time
prevent thermal and chemical losses from the melt

3

Purpose of the mould

primary source for heat extration and allows a solid shell to grow and support the liquid core

4

scale of continuous casting process

huge factories can be 1 km long

5

Mould fluxes

control lubrication (improve surface quality) and heat transfer (minimise defect formation)

6

Mould powders

Mould powders inexpensive, but are asked to perform a number of operations that are vital to producing good quality steel castings

7

What is vital to control and why

Control of heat transfer and lubrication is vital in minimising defect formation

8

advantages of continuous casting

when combined with other processes can produce parts rapidly from liquid steel to coiled sheet in 7 minutes
