The first crucial way to improve the output of rolled thick-walled seamless steel pipe is to improve the speed of the rolling mill. In order to increase the rolling speed, it is required to first address the stability method and specific construction 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.
 
Boosting the amount of feed and growing the elongation are another effective measure to enhance the output of the mill. For this reason, the use of an annular hole block is an ideal solution, which is excellent for stretching the frame stroke without improving the diameter of the roll.
 
The third way to multiply 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 involved to be reasonable, and the manufacturing precision is high to minimize maintenance and maintenance downtime. On the other hand, it is required to improve the mechanization and automation level of the rolling mill to decrease the auxiliary operation time. The third aspect is also a very important development direction. It is essential 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 sharpened out that the increase in the number of lines does not raise the output of the tube mill by an integral multiple, and the preciseness of the finished tube will be reduced for the intermediate process, it is completely available.
