Effection of edger shape on the slab profile;

In this paper, based on the deformation characteristics of tempering hot strip, through the analysis of roll gap shape changed by the temper-mill work-roll wear and with the four-roll temper mill bending function, the ways of determining rational work roll shape is discussed.

The rolling effects of horizontal and edger rolls were both taken into account during load distribution,and iterative computations were done alternately along the width and thickness of work piece by virtue of the equal load function to optimize the rolling schedule step by step.

A series of flexible U sections,changed in its sections,was separately simulated and analyzed by edger roll forming and flat roll forming.

Research and experiment with changeable universal roll method for the axes of vertical rollers of H beam mill;

The peeling on vertical rollers of second stand quenched by high frequency equipment was observed during service due to stress concentration.
