Article Preview

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.
