With a significant feature of strong focus on researching to peer, in heat treatment section the company equip with micro-furnace, carry out experiment to new products and new materials then study its heat treatment process. At the same time, we cooperate with iron smelting company to study the Physical and Mechanical Properties of steel, reasonable mix of components. Especially for duplex stainless steel, super austenitic stainless steel, control and reasonable mix of components is very important, and it is crucial to structure control and mechanical properties. After a long-term exploration research, in the field of nuclear power and aviation, there are special requirements for those special material, we have a lot of valuable experience in the process of forging and heat treatment. In the forging process, after many years of trial practice, the company has formed a complete set of technical process from the raw materials, heating, forging to heat treatment. Especially the high-temperature alloy steel forging, our forging parts NiCr20TiAl, the content of Ni up to 65%, and its forging is very difficult. Now, the high-temperature alloy product forged by us has successfully taken place of imported products.

Roll produced by forging steel ingot. Forging can forge the metallurgical defects such as porosity and shrinkage cavity in the ingot, break the coarse casting structure, and obtain high-quality rolls with dense structure and uniform composition. Forged steel rolls have better strength and toughness, surface hardness uniformity and fatigue resistance than similar cast rolls. (Table 1) in order to meet the specific requirements of different rolling mills and rolling conditions, different alloy elements can be added to the roll steel to improve the roll performance. A certain amount of carbon and alloy elements have the following different effects on the structure and properties of forged steel rolls: carbon can increase the hardness and strength of rolls, reduce plasticity and improve wear resistance; Manganese can increase hardenability and strength; Silicon deoxidizes and improves strength; Chromium can increase hardenability, strength and wear resistance; Molybdenum can increase hardenability, strength and thermal hardness; Vanadium can control the grain size of steel and increase the strength. See Table 2 for the main chemical composition of common forged steel hot rolls and backup rolls.

Closed die forging A heated workpiece is placed in a stationary mold half. The upper mold half is pushed against the workpiece with an applied pressure force and deformed and shaped by the two mold halves. It often requires several strokes before the mold cavity is fully filled. To ensure that such a material is sufficient to fill the mold the workpiece volume is slightly larger than the mold. The design allows for excess material to flow outside the required shape and is trimmed away in a subsequent operation. In some cases, the part is repositioned in the mold to apply further strokes to achieve final size and volume. The closed die forging method allows for Precision forging where ingot size is carefully controlled. More information about closed die forging, refer to closed die forging vs open die casting. -
