Deformation Work

Computational models of deformation and friction work were established by dividing contact arc between strip and work roll into two sliding regions, two braking regions and one stagnating region. A two dimensional temperature field model of work roll was established by finite difference method according to practical boundary conditions. Simulation results show that with the increase of rolling pass, deformation work reduced while friction work increased, except that deformation and friction works at the last pass were the least. The computed rolling forces and work roll surface temperatures agree well with measured values collected from a hot strip mill.

Work roll temperature prediction model is an important part of shape control system in hot strip mill. This article performs work roll mesh generation, and establishes difference equations of each lattice point using two-dimensional alternating difference method. Then, the work roll temperature distribution at any time is acquired after solving equations with chasing method. The model established in this article has high stability, fast solving speed and high operation precision. The results, compared with the measured data, indicate that the model has high reliability and meets the demand of strip quality in hot rolling.

Roll wear model for Hot Strip Mill (HSM) was researched and the factors affect roll wear are analyzed. The simulation program was compiled by program visual C++ language and work roll wear was calculated according to the rolling schedule. Calculation results shows that roll wear like box shape. Strip width affects roll wear clearly. The strip length is one of the important issues which affect roll wear. Work roll wear of F7 top roll middle get to 280μm after a rolling schedule. Roll wear curve calculated by program were good agreement with the wear curve got by high-precision grinder. The results show that the roll wear model has high accuracy.

Thermal Crown

In the paper, the temperature distribution on the work roll surface of a 1750 hot strip mill is studied, and the variety rules of the thermal crown are analyzed. The result of test shows that the work roll thermal crown is significantly affected by cooling. The thermal crown obviously is improved after altering the distance between the cooling pipe and the work roll and changing the type of cooling water faucet. From this paper, it is known that different number of rolling coils cause different thermal crown of the work roll. The final change rule shows that the work roll thermal crown is the largest in Stand 1 and the smallest in Stand 6 in a rolling period.
