Hebei Yogem Castings Co., Ltd

Elderly people in the foundry industry clearly understand that the role of gray cast iron inoculation is very important. What is the purpose of such an important inoculation?   OEM  Castings Supplier  will share with you in detail: The mechanical properties of gray cast iron depend to a large extent on its microstructure. Gray cast iron that has not been inoculated has unstable microstructure, low mechanical properties, and white holes are prone to appear in the thin wall of the casting. In order to ensure the consistency of casting quality, inoculation treatment is essential. Ferrosilicon Inoculant The inoculant used in the inoculation treatment of gray cast iron is added in a small amount, which has little effect on the chemical composition of cast iron, but has a great effect on its microstructure, so it can improve the mechanical properties of gray cast iron and its physical properties are also obvious influences. Good inoculation treatment has the following effects: 1. Eliminate o

As a   Grey Iron Casting Company , share with you. Enhancement method Methods to increase the tensile strength of gray iron castings: 1. A small amount of carbon can be added to the raw materials. In the carbon content of gray iron castings, the carbon content is mostly 2.6% to 3.6%, and the silicon content is 1.2% to 33.0% . In the case of determining the wall thickness of gray iron castings, an appropriate amount of manganese should also be added. Grey Cast Iron Casting Using alloying methods to improve the tensile strength of gray iron castings, adding appropriate amount of trace alloys, chromium, molybdenum, tin and other elements can also significantly improve the tensile strength of gray iron castings, and do a good job of inoculating molten iron. Defect Once porosity or shrinkage occurs on the casting surface, it becomes a waste product. The looseness may first be caused by the unreasonable structure. Porosity, shrinkage porosity, and shrinkage holes are produced in areas with l
