Project name: four-roller thermal sizing machine
Project location: tianjin steel pipe group
Project time: 2008
Project overview: in March 2008, Dalian sage heavy industry equipment co., LTD provided Tianjin steel pipe group co., LTD with a set of sizing equipment, which adopted an active way to fix the thermal diameter of steel pipe and was powered by an alternating frequency variable speed motor.The steel pipe is extruded by horizontal and side roller step by step to the required pipe diameter.
This equipment breaks the traditional method of the seamless steel tube thermal-determination reducing mill, which is usually three-roller type, so that the change of specifications in the past needs to replace the roll series. As long as the change of specifications is made, the roll mold is greatly reduced, the production cost is greatly reduced, and the roll changing time is also reduced.
