Blooming-Slabbing Mill | Article about Blooming-Slabbing ...
In a blooming-slabbing mill, ingots with a mass of up to 30 tons are rolled into slabs up to 2,050 mm in width and 950 mm in thickness, with blooms coming from ingots with a mass of 10–12 tons. Blooming-slabbing mills are inferior to slabbing mills in production capacity as well as according to quality and technical-economic performance factors.

Heavy mills (blooming, slabbing and heavy roughing) use the lower grades (up to 0.60 % C) while billet roughing stands use the higher grades. The addition of about 0.5 % Mo to this type of roll together with small amounts of Ni and Cr (or higher Mn) gives increased strength and reduces the severity of any fire cracks which may occur.

In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2). Blooms are usually further processed via rotary piercing, structural shape rolling and profile rolling.
