AI Technical Summary

Technical Problem

The existing roughing mill guide cooling and descaling device has problems such as rapid wear, cooling water leakage, guide eccentricity, and poor descaling effect, which leads to uneven slab temperature during rolling, unqualified product quality, and frequent equipment failures.

Method used

A composite guide and guard diversion system is designed, including the rolling mill arch, upper rolls, lower rolls, roll cooling water headers and descaling water headers. Through the header mounting frame and the guide and guard diversion water delivery mechanism, the roll cooling water and descaling water are diverted and output, ensuring that the cooling water and descaling water do not directly act on the slab surface.

Benefits of technology

It effectively improves the insulation effect and slab quality during the rolling process, reduces equipment failures, reduces operation and maintenance costs, and improves product quality and production efficiency.

Abstract

The invention discloses a composite guide shunting system for outputting cooling water and double-descaling water of a rolling mill roll system, and belongs to the technical field of design and manufacturing of steel rolling production process equipment. The composite guiding and guarding flow dividing system for outputting the rolling mill roll system cooling water and the double-descaling water can effectively guarantee the heat preservation effect in the rolling process of a hot-rolled plate strip and improve the quality of a plate blank in the rolling process and the quality of a finally-rolled plate blank. The composite guiding and guarding flow dividing system comprises a rolling mill housing, an upper roller, a lower roller, a roller system cooling water collecting pipe and a descaling water collecting pipe, and further comprises a collecting pipe mounting frame and a guiding and guarding flow dividing water conveying mechanism, and the roller system cooling water collecting pipe and the descaling water collecting pipe are arranged on the rolling mill housing above the upper roller in a position-adjustable mode through the collecting pipe mounting frame; cooling water sprayed out of the roller system cooling water collecting pipe, descaling water sprayed out of the descaling water collecting pipe and oxide skin removed by the descaling water are collected and output to the outside of the rolled plate blank through the guide and guard diversion water conveying mechanism under the cooperation of the rolled plate blank and the descaling sprayed water.
