6mm steel plate rolling technique

Abstract

The invention provides a rolling technique for rolling a steel plate of 6mm by using a middle-thickness rolling mill which carries out corresponding settlements on the furnace discharge temperature of a stock, the stock thickness, rolling gates, an automatic gauge control, a rolling force, the self-adaptation coefficients of the rolling force between the gates, an opposite convexity and the matching between the linear speed of a transmission roller gate and the linear speed of the working roller of a rolling mill. The technique solves the problems of waves, bending, camber, frame scraping and waste rolling appearing in the plank stuffs during the testing rolling of 6mm plates of the existing middle-thickness rolling mill, leads the rolling to be stable and can manufacture qualified products in batch.

Description

technical field [0001] The invention relates to a metallurgical industry plate rolling process, in particular to a rolling process for rolling a 6mm steel plate by a medium plate rolling mill. Background technique [0002] 6mm steel plates are now generally rolled by hot tandem rolling mills and steckel rolling mills, but the width of the rolled steel plates is less than 1800mm, and only common steel grades can be produced, which cannot meet market demand. In order to produce 6mm steel plates with a width greater than 1800mm, people try to roll them with medium and heavy plate rolling mills. The specifications of the rolled steel plate in the design of the plate rolling mill are 600-3800mm wide and 6-200mm thick. However, in actual production, many problems such as wavy, camber, frame scraping, rolling waste, etc. will appear in the rolling of steel plates smaller than 7mm by medium and heavy plate rolling mills. The production is particularly unstable, and mass production ...
