Abstract

PURPOSE:To improve the quality of products by setting the doctor blade movable back and forth in sliding to the width direction of the work roll at the top of the splash guard, draining and simultaneously removing the foreign-matter stuck to the work roll. CONSTITUTION:The draining and foreign-matter removing device 10 of this invention is set at the splash guard 7. The blade 11 is attached to the draining and foreign-matter removing device 10 through the blade holder 12. The blade 11 is pushed to the work roll 2 with the actuator 13, and executes draining and simultaneously removing the foreign-matter. The foreign-matter removed is collected in the receiving pan 14. The draining property of the work roll is improved and the foreign-matter stuck to the roll is removed. If the blade is fixed, because the line-flaw is marked to the steel strip 1 with the foreign- matter pooled on the blade 11, so the blade 11 can be move back and forth in sliding to the width direction of the steel strip 1 with the actuator 15 and the electro-magnetic valve 16 in order to prevent for the foreign-matter from collecting at the same position.

Next, experiments were conducted by changing the blade material, rolling blade, etc. As a result, in the case of a metal blade, the pressing force is 3.0 kg/m
If the pressure is exceeded, the surface roughness of the work roll will decrease, so it is necessary to apply a light pressure of 3.0 kg/m or less.
