Gaphite castings is a kind of casting products produced in the casting process. Casting is a smelting process that has a lower cost than steelmaking. The masters who produce graphite castings know that adding graphite carbon raisers in the molten iron can often improve the effect of the quality of graphite castings, it can be seen that graphite carbon raisers are really indispensable for the production and improvement of the quality of graphite castings!

 

Since the carbon atoms in the graphite carbon raiser have changed from the original disorderly arrangement to the sheet-like arrangement, when high temperatures are encountered, the sulfur in the graphite carbon raiser will generate sulfur dioxide gas and escape and decrease, because the sheet-like arrangement of carbon atoms can become the best graphite core. Therefore, whether the graphite carbon raiser has been processed by high temperature graphitization is an indirect indicator to judge whether the graphitization is good. The use of high-quality graphite carbon raiser can often promote the promotion of eutectic spheres in the production of graphite castings. The formation of clusters and improve the distribution of graphite from A to B, so the quality of graphite castings can be greatly improved!

 

 

Graphite carbon raisers are generally treated with high temperature. The graphite nucleation ability of graphite carbon raisers after high temperature treatment is greatly improved, which improves its graphitization ability. Therefore, when producing graphite castings, you should also choose graphite carbon raisers that have undergone high temperature treatment as a casting material!

 

It can be seen that graphite carbon raiser plays an important role in the production of graphite castings. Graphite carbon raisers can often improve the quality of graphite castings. However, if you want to produce high-quality graphite castings, you should also choose graphite carbon raisers that have been treated with high temperature. No wonder many foundry masters often say that they want to improve the quality of graphite castings, and graphite carbon raiser is really indispensable!
