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 refers to slowly heating a metal to a certain temperature, holding it for a sufficient 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 grain size, adjust structure, and eliminate structural defects. More precisely, annealing is a heat treatment process for materials, including metallic and non-metallic materials. Moreover, the annealing purpose of the new material also differs from that of traditional metal annealing.

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 to obtain forgings with certain mechanical properties, shapes, and sizes. Forging (forging and stamping) is one of the two major components of forging. Forging can eliminate defects such as casting porosity that occur during the smelting process of metals, optimize the microstructure, and at the same time, due to the preservation of intact metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. In related machinery, important parts with high loads and severe working conditions are often forged, except for simple shaped plates, profiles, or welded parts that can be rolled.

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.
