Description

Technical Field

[0001] The invention relates to the technical field of galvanized steel pipe production equipment, and in particular to a complete set of equipment for suppressing the inertia of hot-dip galvanized steel pipes. Background Art

[0002] In the production process of hot-dip galvanized steel pipes, the galvanized steel pipes are lifted out of the zinc pot through the lifting hook and drawn out by the magnetic roller, and then the galvanized steel pipes are led to the transverse shifting station by the leading roller. During the leading process, there is still a small amount of zinc liquid in the galvanized steel pipe. This part of the zinc liquid moves upward along with the galvanized steel pipe when it is led up, and moves in a straight line. When the galvanized steel pipe reaches the transverse shifting station, the galvanized steel pipe hits the collision plate, and the transverse shifting device moves the galvanized steel pipe from the leading station to the inner blowing station. During the leading process, the relative speed between the galvanized steel pipe and the zinc liquid in the pipe is zero. After hitting the collision plate, the galvanized steel pipe stops running, and the zinc liquid in the pipe will continue to move forward under the action of inertia. At this time, the zinc liquid left near the pipe mouth will surge onto the surface of the galvanized steel pipe. The surface of this part of the zinc liquid is rough after cooling, which affects the appearance quality of the galvanized steel pipe. We call this phenomenon the tail swinging phenomenon. The faster the galvanized steel pipe is pulled up, the more obvious this phenomenon is. The pulling up speed is related to the size of the galvanized steel pipe. The smaller the pipe diameter, the faster the speed. Therefore, the smaller the pipe, the more obvious this phenomenon is. In order to solve this problem, a set of equipment for suppressing the inertia of hot-dip galvanized steel pipe pulling up has been developed. Summary of the invention
