Added shearing of the roughing mill,continuously excellent turn the passing and parameter of the guide.

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.

The finite element analysis of the crank flying shears;

Research and improvement on the auto control system of flying shear on the high speed wire rolling line;

Optimization of double eccentric pendulum fly shear;

To reform old fly shear used of axial tire type clutch and brake,the questions of incorrect electromagnetic clutching and incorrect brake control on old fly shear are saved.

The horizontal disk shears can not shear rhombohedral section of rolled material before it is came into finish rolling mill,and so the vertical shaft type disk fly shears is designed and it's practical calculating formula is got based on the priciple of operation of disk type shear machine and fly shears.

Adjustment of speed and position parameters on motion control system of start-stop shear;

Reform of Continuous Shear in Finish Rolling;

3 shear wasn't satisfied with the new production requirement.
