Guide plate for rolling mill and its manufacture and repair method

Abstract

The guide plate may have tungsten carbide blocks with hardness over HRA80 adhered with inorganic adhesive to its wearable parts. During its manufacture and repair, the wearable parts are machined, cleaned and adhered with tungsten carbide blocks. The guide plate has high wear resistance, crack resistance and long service life. The guide plate is suitable for use of rod rolling mill, wire rolling mill and shape steel rolling mill.

Description

technical field [0001] The invention relates to a rolling mill guide plate and its manufacturing and repairing methods, in particular to a combined rolling mill guide plate. The technical solution claimed belongs to the rolling mill guide plate technical field. Background technique [0002] The guide plate material of the rolling mill that existing rolling mill uses is cast steel or cast iron, is integral structure, and whole guide plate hardness is the same, and this has brought a lot of inconveniences to use guide plate use. On the one hand, since the guide plate is used in different positions, the degree of wear is also different. The hardness of the guide plate used should be different. The parts that are easy to wear should have high hardness, and the hardness of the parts that are not worn can be reduced. Low, easy to wear, poor wear resistance, premature wear of the guide plate, resulting in time-consuming and laborious replacement work, and hi...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a guide plate for combined rolling mills with high hardness, high wear resistance and crack resistance, which can damage the guide plate of the rolling mill due to local wear and tear. Repeated use, the guide plate can adopt different hardness of the guide plate according to the requirements of use, so as to overcome the shortcoming of the low life of the guide plate in the prior art
