Rolling mill flying scissor blade cooling method and cooling device thereof

Abstract

The invention relates to a rolling mill flying scissor blade cooling method and a cooling device thereof. In the cooling method, a heat-sensitive sensor is arranged to detect the movement and the position of wire stocks in the process in which the wire stocks are transported to a flying scissor blade, and a detection signal is transmitted to a control circuit. The method comprises the following steps: sending out a hot metal existence / non-existence detection signal and controlling the flying scissor blade to halt or stand by; or spraying water to cool the flying scissor blade and automatically delaying the close of sprayed cooling water. According to the cooling method and the device thereof disclosed by the invention, on the premise of saving water and preventing water from splashing and infiltering into a bearing oil seal, a more effective water cooling mode is adopted to cool the flying scissor blade, so the temperatures of the flying scissor blade as well as a cutter shaft and a crankshaft thereof can be greatly reduced, the shearing quality of flying scissors is improved, the overall working life of the blade and the flying scissors is prolonged, and the failure rate of the whole device is reduced.

Description

Technical field [0001] The present invention relates to a metallurgical process device, more specifically, the present invention relates to a process device of a metallurgical rolling mill and a process method thereof. Background technique [0002] As an important device for metallurgical technology, high-speed wire rod rolling mills, in order to meet product requirements and ensure the continuous and normal wire rod production process, usually after the 6# rolling mill in rough rolling (V or H rolling direction) and the 7# rolling mill in middle rolling Previously, a crank-type flying shear with blades (usually referred to as 1# flying shear) was configured to implement important functions such as head-cutting and tail-cutting of the wire rod, and to prevent subsequent accidents from accidentally breaking; crank start-stop type 1 #Flying shears performance parameters can usually reach: the maximum shear section 5026mm2 (diameter 80mm), the length of the cutting head is 50~200mm,...

AI Technical Summary

Problems solved by technology

[0008] It can be seen from the above that the traditional natural cooling method of 1# flying shear has the following series of disadvantages: not only affects the smooth progress of production, causes production misproduction, affects the yield of rolled products, but also increases the equipment operating cost
