Carbon raiser for environmental friendly foundries is a chemical additive that's used during the smelting and casting of iron and steel. This product makes up for the loss of carbon content in molten metal due to smelting time, holding time and longer overheating time. It helps reduce impurities, and prevents oxidation. It is a vital auxiliary additive for the production of steel and iron. There are several types of carbon raisers, and each type is available with different fixed carbon percentages.
The most common way to raise carbon is by calcining petroleum coke. This is done by heating the raw coke up to very high temperatures. This process removes the majority of moisture and volatile substances. It also reduces its sulfur content. This product can be used to recarburize cast iron by using the electric furnace. It can reduce or eliminate pig iron and increase the amount used for smelting.
The continued shift to electric vehicles (EV) is another factor that drives the growth in carbon raisers. It will also require large amounts of iron and steel for production. This will lead to an increase in demand for these products. Additionally, the growing emphasis on renewable energy sources is expected to lead to an increased need for cast iron, which requires a high level of carbon in order to produce.
Directly or through injection, a carbon raiser can either be added to molten metal. It can be used to increase the carbon in steel to improve the properties of the metal, or to help prevent oxidation by coating ferrous metals with a crystalline structure graphitic that doesn't react quickly. It can also be used to improve the casting of ductile and gray cast iron.
Carbon raisers are used to recarburize steel. They can increase the amount used of scrap steel, reduce the use of pig steel or even eliminate it, as well as improve the quality and metallurgical properties of the castings. Carbon raisers should only be added in small amounts to the molten metal in the electric furnace feeding method to prevent excessive oxidation.
Recarburizers of superior quality with a carbon content fixed at 99% are available from us. The recarburizer is produced with high-quality base materials using the latest scientific techniques, in compliance with predefined specifications. It is used to smelt and recarburize cast iron alloys, as it also works for other metals that contain carbon. It is characterized by a uniform grain size that allows for efficient dissolution of the metal in molten state. Low sulfur and ash levels are also maintained to improve metallurgical process and minimize impurities. This product can be used to smelt ductile, gray and other metal alloys that contain carbon. This product has excellent casting properties, such as higher tensile strengths and ductility.
