Slabs are a semifinished product used in the manufacture of wide sheets. Unlike blooming mills or blooming-slabbing mills, slabbing mills are highly specialized rolling mills with two pairs of rolls—horizontal and vertical. They are installed in metallurgical plants and in rolling shops equipped with high-output strip mills.

A continuous hot-rolling mill may have a conveyor that is several thousand feet long. The steel slab exits from a slab reheating furnace onto the beginning of the conveyor. Surface scale is removed from the heated slab, which then becomes thinner and longer as it is squeezed by horizontal rolls at each mill, usually called roughing stands.
Details 
Hot rolling takes advantage of the metal's ductility at high temperatures to execute great section reductions. Flat product hot rolling mills are fed from flat slabs, previously heated and homogenized in reheating furnaces in order to achieve suitable temperatures for the subsequent transformation process.

Rolling speeds at the finishing mill will be higher than at the roughing mill. Hence rolling cannot be done with stock present in both roughing and finishing mills. Finishing mill rolling of reheated slab: The finishing mill usually has five to seven finishing roll stands, which reduce the thickness of the transfer bar down to the gauge required.

A method for reducing the thickness of a slab of metal under conditions which tend to cause alligator defects to occur. The method comprises the steps of directing a relatively thick slab of metal several times through a rolling mill or mills to incrementally reduce the thickness of the slab until the thickness approaches a value that tends to produce a longitudinal and lateral …
