Influence Factors of Rolling Force

Influence Factors of Rolling Force

The factors affecting the rolling force are: Absolute reduction In the roll diameter and friction coefficient of the same conditions, the contact area between rolled part and roll becomes large along with increase of absolute amount of press-down, so the rolling force increases. Roll diameter The contact area increases as the roll diameter increases, while the…
Create Extreme Thin Steel

Create Extreme Thin Steel

In 2016, TISCO successfully developed hand-tear stainless steel with a thickness of only 0.02mm, and in 2020 TISCO created another hand-tear stainless steel with a thickness of 0.015mm, breaking the world’s thinnest record. Ultra-thin high-grade non-oriented silicon steel, thickness of 0.15mm 2023.March, BaoWu New Steel Group’s ultra-thin high-grade non-oriented silicon…

Dedescaling Nozzle

Dedescaling nozzle as a key component affects the surface quality of hot-rolled products directly, if the descaling nozzle is not used properly, the surface of the product is easy to press into the iron oxide or produce black marks and other surface quality problems; will also increase roll consumption. When the high-temperature slab is subjected to high-pressure…
