manufacturing process of thin slab continuous casting in steel.

摘要

it's the steel in a mould (1) in which at least the outlet section has a width less than or equal to 60 mm.we extract from this mold, a slab (2) having a thickness less than 60 mm and with a shell.it makes the slab in secondary cooling, during which a continuous layer of cooling liquid under pressure (3) on at least a portion of the surface of the slab.and it controls the flow of cooling fluid on the surface of the slab in the direction of the development of it.the casting speed is more than 3 m / min, and is preferably in the range 6 m / min and 20 m / min).is the slab in the secondary cooling, until a surface temperature of less than 800 degrees c, and preferably less than 600 degrees celsius.the thin slab is directly hot-rolled.
