Technical Field

[0001] The utility model relates to the field of steel rolling equipment, in particular to a water scraper device. Background Art

[0002] The lower water retaining plate at the outlet of the finishing mill is mainly composed of a scraper plate and a lining plate. It is installed on the outlet guide of the 1700 line finishing mill F4-F7 and is in direct contact with the roll surface of the working roll. It plays a role in blocking the cooling water of the roll, so that the cooling water of the working roll cannot directly contact the surface of the steel plate, which plays a key role in the surface quality of the produced strip.

[0003] However, in actual applications, since the lower water retaining plate in use is made of gray cast iron, when it contacts the lower working roll, the roll is in a rotating state, resulting in abnormal wear on the roll surface and fall-off of the oxide film on the roll surface, causing the rolled strip products to often have knife mark defects, affecting production and unplanned roll replacement, and posing a major quality risk.

[0004] At present, the traditional wiper device is made of cast iron. If the wiper is worn too much by the working roll surface, it is easy to cause uneven peeling of the oxide film on the roll surface, affecting the surface quality of the product. Utility Model Content
