Three Dimensional Roll
Technical details
The service life of cemented carbide roll ring on tension reducing mill for hot rolled seamless steel pipe is more than 50 times that of ordinary cast iron roll ring, and the surface quality and dimensional accuracy of steel pipe are also greatly improved. According to the condition of seamless steel tube stretch reducing mill (rolling force, speed and pipe diameter), the combined hard alloy stretch reducing roll is used to obtain high cost performance.
