Rolling facility and rolling method of stainless steel plate

Abstract

The present invention relates to a rolling facility and a rolling method of a stainless steel plate. The rolling facility according to the present invention comprises: a plurality of rolling roll setswhich are composed of at least a pair of rolls facing each other with a workpiece being conveyed therebetween and are provided in a conveying direction of the workpiece; a plurality of rolling oil supply means, provided corresponding to each of the rolling roll sets, for supplying a rolling oil to the rolling roll sets; a plurality of cooling means, provided corresponding to each of the rolling roll sets, for supplying a gas to the workpiece and the rolling roll sets; a gloss measurement means, disposed between the rolling roll set most rearwardly disposed in the traveling direction of the workpiece and a winder for winding the workpiece, for measuring the surface gloss of the workpiece; and a control means, connected to the gloss measurement means and the plurality of cooling means, forcontrolling an amount of gas supplied by the plurality of cooling means according to the surface gloss measured by the gloss measurement means.

Description

technical field [0001] The present disclosure relates to rolling mills and methods of rolling stainless steel sheet. Background technique [0002] Continuous rolling, as a method of rolling a workpiece to a target thickness at one time by allowing the workpiece to be rolled to pass through a plurality of work rolls arranged in the conveying direction of the workpiece, has become a method that provides remarkably excellent productivity. rolling method. [0003] Compared with the work rolls used for reversing rolling, the work rolls used for continuous rolling have a relatively larger diameter, and the viscosity of the rolling oil is higher. In addition, since the number of rolling mills arranged in the entire rolling line is limited, the reduction per stand is relatively high, which may become a rolling condition of high pressure. [0004] Therefore, when a workpiece having high deformation resistance such as stainless steel is rolled at high speed under forced rolling cond...

AI Technical Summary

Problems solved by technology

However, when the viscosity of the rolling oil increases, there may be a problem that the surface gloss of the workpiece decreases

In the case of workpieces where surface gloss is very important such as stainless steel being rolled, the above issue may be a more sensitive one
