Permanent Steel Manufacturing Co.,Ltd have years of experience in manufacturing of carbon steel pipe,stainless steel tube, hollow section, and pipe fittings.

The first important way to increase the output of rolled thick-walled seamless steel pipe is to increase the speed of the rolling mill. In order to increase the rolling speed, it is necessary to first solve the balance method and specific structure of the inertia force and inertia torque of the rolling mill frame, the strength and rigidity of each component, and the problems of lubrication, cooling, and service life.

Increasing the amount of feed and increasing the elongation are another effective measure to increase the output of the mill. For this reason, the use of an annular hole block is an ideal solution, which is advantageous for lengthening the frame stroke without increasing the diameter of the roll.

The third way to increase the output of cold-rolled pipe mills is to increase the effective working coefficient of the mill, which will involve a variety of problems. On the one hand, the design of the rolling mill is required to be reasonable, and the manufacturing precision is high to reduce maintenance and maintenance downtime. On the other hand, it is necessary to improve the mechanization and automation level of the rolling mill to reduce the auxiliary operation time. The third aspect is also a very important development direction. It is necessary to realize the cold rolling mill without stopping, continuous loading and continuous rolling.

The fourth measure to increase the output of the rolling mill is to increase the number of tubes simultaneously rolled. It should be pointed out that the increase in the number of lines does not increase the output of the tube mill by an integral multiple, and the precision of the finished tube will be reduced for the intermediate process, it is completely available.
