The article describes the characteristics in structure of edger stand at rougher area of 2150mm hot continuous mill supplied for Anshan Steel and the merits and shortcomings on the design in comparison with similar edger stands home and abroad.

Study on on-line temperature model in rough rolling zone of hot rolling strip and its application

An aggregate equal load function was developed and applied to the load distribution on a double-stand mill during hot strip rough rolling.

To improve the width control precision of hot strip during rough rolling for prediction,the PSO(particle swarm optimization) algorithm is used to train neural network with the actually measured data in PANSTEEL.

Simulation system of hot strip rough mill;

The communication interfaces among the process computers of heating furnacre,rough mill and finishing mill as well as the interface between the process computer and data center are also specified.

,the rough mill control system was designed,including hardware figuration,network framework,software functions,etc.

Breakage mechanism and application of the bottom main drive spindle in a R2 roughing mill during hot rolling by finite element analysis;

The screwdown system of four-roll reversing roughing mill in Tiangang Group requires high control precision, the speed control of screwdown motor is the key factor.

In hot rolling process,reheating furnace and roughing mill are controlled separately in general,and as a subsequent equipment of reheating furnace,roughing mill can not feed useful rolling information back to reheating furnace in time,so that reheating furnace can not heat slabs according to the requirement of roughing mill.
