Therefore, different types of rolling mills have different requirements for rolling mill rolls. For example, billets and slab bloomer rolls must have good torsional and bending strength, toughness, and bite in, hot crack resistance, thermal shock resistance, and abrasion resistance.

This means that a bar production line with a single shift (8h) output of about 1000t has to replace the rolling groove 3-5 times per shift, resulting in a long cumulative time for roll changing and groove changing, frequent adjustment of rolling mill and frequent production accidents. As a result, the operation rate of the whole production line ...

Rolling mill guides are to help the billet safely pass through the rolling mill, clear oxide scale of billet, and make the surface of billet smoother. Rolling mill guides play a main role in ensuring the surface quality of the rolled products.
