Carbon Raiser For Foundry

Carbon raiser for foundry is an auxiliary material used in steel and iron smelting and casting to increase the carbon content of the molten metal. Petroleum coke and coal calcined are its main raw material. Its processing is primarily based on graphitization and calcination. Due to its high fixed content of carbon, low sulfur levels and excellent permeability, it makes an ideal additive in the smelting process for ductile steel and iron alloys.

Carbon content can decrease during the steel or iron smelting processes. This will affect the final quality. For this reason, Carbon raiser is used during the melting process. For the production of steels and cast irons of the highest quality, it is essential to use carbon raisers in order to reach the desired carbon level.

Four types of carbon raising agents are available for foundry. These include calcined coal, petroleum coke, graphitized coke, and composite. The anthracite carbon raised is made with high quality coal that has excellent properties such as low sulfur and ash. The petroleum coke carbon raiser is made from petroleum coke, which has been calcined under high temperature and has been graphitized to reduce impurities. The graphitized Petroleum Coke Carbon Raiser is the latest type of carbon raiser. It has a higher fixed carbon content, and it can be used directly in smelting.

This composite carbon raising agent is composed of petroleum coke with a type of synthetic graphite. The material has low ash, sulfur and good permeability. It's a very effective smelting addition, with easy control of the carbon level in molten Iron. The Carbon raisers used in foundries are all highly reactive and can have a lasting effect. It is important to add Carbon raisers at the right temperature and timing. Stirring the liquid steel or iron should also be performed in order for the raisers' absorption rates to be increased.

Carbon raisers can be used widely in the steel-making and cast-iron-making processes to boost the carbon level of the iron molten, increase product quality, reduce energy usage, etc. In the smelting of ductile cast iron, carbon raisers can significantly reduce the consumption of steel scrap and even eliminate the need for using pig iron, which is beneficial to the environment. Carbon raisers are therefore a vital auxiliary material in the melting and casting of steel, cast iron and other metals.
