Failure cause analysis and measure of roller ring in high speed wire rod mill
There are problems in production of high speed wire rod mill,such as breaking roll of hard alloy ring and low steel passing amount of special type pass.Failure causes of radial and axial cracking of hard alloy ring,peeling of working layer and low pass volume in high speed wire rod rolling mill are analyzed.Combined with requirements of hard alloy roller ring in grinding,installation,cooling and other aspects of usage,by reducing rolling process of stacking steel,control amount of roll-ing and grinding,install roller ring correctly,tungsten carbide content of hard alloy roller ring is increased to more than 90％,ensure pH value and solid particle content of cooling water,control cooling water pressure 0.4～0.6 MPa,water flow 250～300 L/min and other measures to solve practical application of hard alloy roller ring problems.
