The Application of New Forging Process on Heavy Back-up Roll;

The tension-tension fatigue properties of Cr4 and Cr5-type steels for back-up rolls were measured by using the group test method,the microstructure of the steel was also studied by means of XRD,SEM.

The wear model for back-up roll on wide hot strip tanderm mills was developed by dividing the barrel into uniform slices on the basis of measured contours of worn back-up rolls.

The Optimize Practice of the After Forged Heat Treatment Process for the Large Forged Steel Backup Rolls.;

The Manufacturing of 5%Cr Backup Roll for 2050 Hot Strip Mill of Baosteel;

Improvement in shape and transverse error of plate by backup rolls with variable contacting length;

The original specification,assembly structure and cone sleeve's structure characters of filmatic bearing for back up roll on 1700mm tandem hot rolling mill in BISC is introduced here.

By sampling at the rupture origin position of back up roll,applying the failure analysis means,combining the these analysis means such as chemical composition data,mechanical property target,macroscopic and microscopic metallurgical observation and scanning electron microscope etc,its rupture course and reason have been analyzed.

occur easily when grinding back up roll bearing inner ring.

Anti-peeling off research and optimization design on the supporting roller of continuous hot rolling mill;

A type of height-adjustable supporting roller for tubes and tubular tools is introduced.

he usage and failure condition of φ1 550 back-up rolls were analyzed in this paper.

The design of the hydraulic system of supporting roll puller.
