By compared the difference of the type start and stop cut shear and the other tradition flying shear,this paper explaines the reason to choose the type start and stop cut shear in Angang 260 rolling-link clubbed steel.

D thermal mechanical coupled elasto plastic FEM has been used to simulate the deformation of workpiece in 4 pass bar continuous rolling process.

In view of the heavy weight,difficult installation and adjustment of guide and guard of vertical stand for finish product of bar continuous rolling,the vertical stand is replaced by horizontal stand for finish product.

The operation guide system is used especially for continuous bar rolling mill It offers the engineer and the operating personnel with a model test software In this paper, the introduction has been given about the design idea, scheme, functions and use of the continuous bar rolling mill model software It has been verified in the us

The optimal selection principle of roll material for continuous bar mill as follows:the pearlite-ferrite nodular cast iron roll for the preceding roughing stands,the pearlite nodular cast iron roll for the later roughing stands and intermediate stands,and the needle nodular iron roll for finishing stands.

The model of static recrystallization of 20MnSi steel and its application in hot continuous rolling of bars;
