The carbon raiser is also known as recarburizer or carbon additive. It's an important material for the production of iron alloys. It can increase the amount of carbon in the molten metal to improve its strength, hardness and wear resistance. It can also reduce the slag formation and improve the ladle metallurgy furnace operation. It is widely used in different industries, such as machinery, chemistry, electricity, and metallurgy.
Carbon raisers come in a wide variety of types, depending on the raw materials used and the production process. There are many types of carbon raisers, depending on their raw materials and production processes. These types all increase the carbon in molten metal, but differ in graphitization.
The choice of a Carbon Additive depends on several factors including the steel quality requirement, cost of the carbon product and its availability. However, the best choice is usually coke, due to its relative low and consistent S/P content and high carbon content. Coke's porous structure allows metals to penetrate its small fissures more easily and consume its carbon content. It is also more convenient and less expensive.
Carbon-containing material is added to the smelting processes to improve graphitization in molten metal and prevent shrinkage. These carbon-containing materials can vary widely in their quality, which can lead to various problems during the production of iron castings. These problems are often traced to the carbon-containing materials used as the carbon raiser.
It is important to select a carbon raiser of high quality for your iron alloy manufacturing. This will help you avoid these problems. Look for carbon additives that have been produced using the electric calcining technique. This process eliminates impurities like sulfur, gases (nitrogen and hydrogen), ash and volatiles, as well as moisture. It also improves the quality and performance of carbon-containing materials.
The carbon-containing substances used in the production of the carbon raisers are also free from impurities including nitrogen, phosphorus or sulfur. This will ensure that the carbon is arranged correctly. This can reduce gas porosity as well as shrinkage. Elkem's range of carbon-containing products is designed specifically to be used in iron alloys as carbon additives. These products are carefully selected for purity and graphitization. They also undergo a rigorous quality control process to ensure they deliver the best possible performance. Our carbon additives will help you produce castings of the highest quality with superior mechanical properties. You can also use them to reduce the amount of pig iron in your smelting processes, or eliminate it altogether. It can reduce your overall iron alloy production costs.
