Using hot-rolled pipes as raw materials, after pre-treatment such as acid washing and lubrication, rolling is carried out at room temperature. Cold rolling followed by heat treatment to eliminate work hardening, followed by finishing

Annealing is a metal heat treatment process that involves slowly heating a metal to a certain temperature, holding it for a sufficient amount of time, and then cooling it at an appropriate rate. The purpose is to reduce hardness and improve machinability; Eliminate residual stress, stabilize dimensions, reduce deformation and crack tendency; Refine granularity, adjust structure, and eliminate structural defects.

There is sufficient inventory in the factory, including round bars, seamless pipes, plates, flanges, steel strips, with a complete range of models to meet various customer needs

Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation, in order to obtain forgings with certain mechanical properties, shapes, and sizes. Forging can eliminate defects such as casting pores that occur during the metal smelting process, optimize the microstructure, and maintain complete metal flow lines. At the same time, the mechanical properties of forgings are usually better than castings of the same material.

The form of the receiving frame and the position of the ring component, the ring rolling machine is divided into two types: vertical and horizontal. For the convenience of operation, most small and medium-sized ring rolling machines adopt a tilted vertical position, while large ring rolling machines, starting from the convenience of working translation and transmission, mostly adopt a horizontal position.
