What Is Carbon Raiser?

Carbon raiser, also known as recarburizer or carbon additive, is an important raw material that is added to metal alloys like steel and iron in the metallurgical industry. This material enhances carbon levels in molten metal to improve the quality of the end product. It is widely used in the steelmaking and casting processes for adjusting carbon content, promoting reduction reactions, and influencing other characteristics of molten metal.

Besides improving the quality of the final products, carbon raisers are also cost-effective. They are produced from carbon-rich materials, such as anthracite coal, calcined petroleum coke, or graphite, and then injected into different metals to achieve the desired carbon concentration. Some common applications of carbon raisers include steelmaking, cast iron recarburization, and ladle metallurgy.

Different types of carbon raisers are available in the market according to their specific production process and application. For example, recarburizer for high-grade pig iron is usually made of calcined coal, whereas carbon additive for steel making or casting can be divided into four types: calcined petroleum coke, graphite,graphitized petroleum coke, and anthracite. These products are widely used in the steelmaking or casting processes, because of their high carbon concentration, low sulfur content, and good reactivity with molten metal.

During the steelmaking process, carbon raisers can be added to the melt to adjust the level of carbon in molten metal. This is essential to achieving the desired properties of the finished steel. By increasing the carbon content of the molten metal, carbon raisers can increase the strength and hardness of the steel, while also enhancing its ductility and wear resistance.

A carbon additive can be used for recarburizing melted steel, as well as for the production of ductile and gray cast irons. It can be added as a charge carbon in electric arc furnaces, blast furnaces, and ladle metallurgy furnaces to increase the steel's tensile strength and yield strength. It can also be used to reduce the chill depth in cast irons.

In addition to enhancing the mechanical properties of metals, carbon raisers can also be added to the molten metal to improve its chemical composition and reduce its impurity levels. This is particularly useful in achieving precise control over the chemical and physical properties of molten metals, which is especially important for various industrial applications.
