>Blooming Mill | Article about Blooming Mill by The Free ...
The design of the majority of plants producing section-shaped rolled products corresponds to the traditional layout: the blooming mill—continuous billet mills—shaping mills. The leading unit of the shaping cycle is a two-high reversing blooming mill; hence, the capacity of the entire cycle is determined by the productivity of the blooming mill.
>Continuous Rolling, Semi-continuous and Slit Rolling of ...
When the rolling mill produces the same size products with the same size billet, only 1/2 of the cross-section needs to be rolled, so the rolling pass can be reduced. At the same time, double or multi-wire rolling can be realized, which greatly improves the output of the rolling mill, which is particularly important in the production of small ...
