JPS5781905A - Tandem mill - Google Patents

Abstract

PURPOSE: To permit disposition of plural rolling mills in proximity by providing a broken plate pull-up machine between tandem rolling mills, and providing shearing machines on the inlet and outlet sides of the tandem mills.

CONSTITUTION: The broken plates in rolling mills are cut by using emergency shearing machines constituted of an upper blade 21 and a lower blade 22. More specifically, the rolled material is cut between the N-th rolling mills and the N+1st rolling mill, and the rolled material is cut by the shearing machine provided between the N+1st rolling mill and N-th rolling mill. The trailing end of the cut material is delivered to the outlet of the N-th rolling mill by the roll of the N-th rolling mill, and is pulled up to the upper part of the rolling mills by a broken plate pull-up machine 16. At this time, a floor plate 20 is moved in a horizontal direction to form an opening part necessary for pulling up the broken plate and the machine 16. If the broken plate is treated in this way, the treating of the broken plate is made possible without providing clearances between the respective rolling mills.
