Carbon Additive

Carbon additive is widely used in the foundry industry, with low sulfur and low nitrogen characteristics of the carbon additive in the field of casting are outstanding, it can effectively reduce the tendency of the casting white mouth, and reduce the honeycomb holes in the casting, significantly improve the quality of the casting. The raw materials used in the production of carbon additives are mainly natural graphite, artificial graphite, petroleum coke, calcined coal, etc. The use of the calcination process can significantly reduce the content of sulfur and nitrogen elements in the carbon additive, thereby improving the quality of the carbon additive.

Different carbon additive has different internal fixed carbon content. The absorption rate of graphitized carbon additive is effectively increased, and compared with coal carbon additive, graphite carbon additive has fewer impurities, which can improve the distribution pattern of graphite when producing graphite castings and effectively improve the quality of graphite castings.

The use of petroleum coke as a raw material for carbon additive can make it have a higher ignition point, effectively enhance the casting furnace temperature, provide a constant temperature environment for raw materials, and conducive to the conversion of elements in raw materials, through calcination treatment petroleum coke carbon additive can significantly reduce its internal sulfur and other harmful elements, in the casting use is very widely used.

High-quality carbon additive has a high fixed carbon content, strong oxidation resistance, high absorption rate, low sulfur, and low nitrogen characteristics, China's carbon additive because of its abundant domestic high-quality carbon raw materials, in terms of quality is relatively good, the production of carbon additive not only high absorption rate, in addition to ash impurities are low, in the casting can play the best effect. With the development and application of carbon additive in different industries, it is also widely used in automobile brake pads, wear-resistant industry, metallurgical industry, electronic product production, and other fields.

We are a professional manufacturer of carbon additive in China for 20 years, providing reliable quality carbon additive products to global customers, including: graphite, petroleum coke, calcined coal and other types of carbon additive products with advanced production technology.
