Aiming at the machining difficulties of 1 100 mm rough rolling mill,the machining device for the transition tapered hole in the bore of rolling mill screwdown mechanism has been designed to be used on common boring machines.

In this paper,established the virtual prototype and dynamics simulation about the hold-down system of rolling mill are presented in detail.

Annealing texture of CSP low carbon steel sheet under different cold rolling reduction ratio

The effects of coiling temperature and cold rolling reduction ratio on deep-drawing properties of low-carbon sheets hot-rolled by FTSR of Tangsteel were investigated in laboratory.

Low-carbon steel strip produced at different coiling temperatures and different cold rolling reduction ratios were used.

It is found that the recrystallization temperature decreases with the increase in cold reduction,and large reduction in cold rolling ma.

The effect of cold reduction on the planar anisotropy of cold rolled and annealed low carbon steel sheets microalloyed with Ti was studied under prescribed processing conditions in the lab.

Mechanical properties testing、SEM and TEM was used to study the effects of cold rolled reduction and aging temperature on the cohesion of the weak interface of DISC.
