Forged Shell Heavy Steel Forgings Special Sizes Manufacturing & Mining Cylinder Forgings

Quick Detail:

1. Forged Shell , cylinder proper forgings, Shell body forging parts, Solid forgings

2. Non-standard and common or uncommon sizes diameter flange

Large size Shell forging section size in the production process is very complex, so the production of the product needs to consider a lot of factors, the main consideration is the following.
1. The microstructure and properties of forgings are not uniform;
2) coarse grain size of forging;
3) there is a large stress in the forging;
4) some forgings prone to white spot flaw.
Therefore large cylinder forging heat treatment in addition to eliminate stress, reduce the hardness, the main purpose is, first of all, prevention of forging white spots appear, followed by improving the uniformity of the chemical composition and fine tune forging organization.
In the production of large cylinder forgings, consistent with the current view is that: the white point is the results of hydrogen and the internal stress of steel. The most commonly used method is to prevent the white spots in just cooled to 650 to 540 degrees when using hydrogen diffusion speed for thermal insulation.
