Compared with castings, the microstructure and mechanical properties of metals can be improved after forging. Due to the deformation and recrystallization of metal, the original coarse dendrites and columnar grains are transformed into equiaxed recrystallization structures with fine grains and uniform size, so that the original segregation, porosity, porosity and slag inclusion in the ingot are compacted and welded, and its structure becomes more compact, which improves the plasticity and mechanical properties of metal. According to forging temperature, it can be divided into hot forging, warm forging and cold forging. According to the forming mechanism, forging can be divided into free forging, die forging, ring grinding and special forging.

 Free forging

Free forging refers to the processing method of forging with simple universal tools or directly applying external force to the blank between the upper and lower anvil of forging equipment to deform the blank and obtain the required geometric shape and internal quality. Free forging is mainly based on the production of forgings with small batch. Forging equipment such as forging hammer and hydraulic press is used to form the blank and obtain qualified forgings.

 Die forging

A forging method in which a metal blank is formed by a die on a special forging equipment to obtain forgings. Die forging process has the advantages of high production efficiency, low labor intensity, precise size, small processing allowance and complex shape forging. Suitable for mass production.

 Ring rolling

Through the active rotation of the rolling wheel, the ring blank is driven to rotate, and the ring blank drives the core roller to rotate. At the same time, the center distance between the roller and the core roller is gradually reduced, and the diameter is gradually expanded until the required cross-sectional shape is formed. Ring rolling is widely used to produce bearing inner and outer races, gear rings, train wheel rims, bushings, flanges, bridge crane wheel rims and so on.

Why use XAT Forging?

●Strength, plasticity and toughness of forgings produced by XAT can meet the requirements of various industrial fields for mechanical properties of materials.

●Forging can effectively remove the defects and inclusions inside the metal material, so that the surface is smooth and the finished product is uniform and beautiful.

●Fast production speed, short production cycle, can meet the needs of large quantities of orders.
