Continuous caster - main equipment and process technology

A modern steelmaking plant is a combination of various metallurgical units. After refining outside the furnace, the molten steel is poured into the continuous caster to solidify it into billets. The coupling machine starts to connect the important link between steel rolling and rolling. The solidification of molten steel in the continuous caster is affected by the interaction of various physical processes such as flow, heat transfer, mass transfer and stress.

Technology-common sense of rolling mill

In the early days, two high rolling mills were used to roll plates and strips. Because the rolling pressure is very large when rolling plate and strip, in order to ensure sufficient rigidity, the roll diameter is required to be large enough. However, with the increase of roll diameter, the elastic flattening of roll also increases, so the two high mill can only roll thick narrow strip.
