Carbon raiser, also known as carbon additive or carbonaceous material, is a substance used to increase the carbon content in various metallurgical processes. It is primarily used as a carbon source in the production of steel, cast iron, and other metal alloys. Here are the specifications and properties of carbon raiser:

The specifications and properties of carbon raiser can vary depending on the specific product, source material, and production process. It is essential to consider these factors to ensure the appropriate carbon addition and desired results in metallurgical applications.

1. Composition: Carbon raiser is composed mainly of carbonaceous materials, typically in the form of petroleum coke, anthracite coal, or graphite. The exact composition and carbon content can vary depending on the specific product and application.

2. Carbon Content: The carbon content of carbon raiser is a crucial specification. It is typically high, ranging from 85% to 99%, depending on the source material and production process. Higher carbon content provides more efficient carbon addition and helps achieve the desired carbon levels in the final product.

3. Volatile Matter: Carbon raiser contains volatile matter, which refers to the substances that can be driven off when heated. The volatile matter content can vary, but it is generally lower than in other carbonaceous materials like coal. Lower volatile matter content reduces the potential for unwanted emissions during the carbon addition process.

4. Ash Content: Ash content represents the non-combustible mineral residue left after the carbonaceous material is burned. Carbon raiser typically has a low ash content, which is desirable to minimize impurities and maintain the desired carbon levels in the final product.
