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.

A continuous rod hydrophobic interaction chromatographic column consisting of poly(glycidyl methacrylate and ethylene glyeoldimethacrylate) was prepared by a free radical polymerization and used in the separation of snailase.

Continuous rod ion-exchange chromatographic columns have been widely Used in separation and purification of protein, peptide, nucleic acid, polyribonucleotide, and polysaccharide in recent years due to their excellent characteristics such as 1).

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
