What's the raw material of carbon raiser

Carbon raisers are important chemical substances used in metallurgical furnace charges to increase the carbon content, widely used in the iron and steel smelting and casting industries. Their core function is to adjust the chemical composition of molten iron to achieve specific carbon content requirements.

The raw materials for carbon raisers are diverse, but petroleum coke and pitch are the most common. Petroleum coke, a solid byproduct of petroleum pitch or heavy oil processing, has high calorific value, low volatility, and high purity, making it a primary raw material for carbon raiser preparation. Pitch, an oily substance extracted from petroleum sand, contains high levels of carbon and hydrogen, and is also suitable for carbon raiser preparation.

In terms of manufacturing processes, carbon raisers are mainly divided into dry and wet methods.

Dry preparation requires calcining the raw materials at high temperatures to convert them into pure carbon compounds. During this process, temperature control and calcination time are crucial to ensure the quality and performance of the final product.

Wet preparation involves immersing the raw materials in specific chemical agents, drying them, and then calcining and carbonizing them. While this method is relatively complex, it can produce carbon raisers with specific properties.

It is worth noting that the production and use of carbon raisers both have certain environmental impacts. The production process consumes a large amount of energy and raw materials and may generate emissions of greenhouse gases such as carbon dioxide. During use, carbon raisers may also release harmful gases and metallic pollutants. Therefore, effective environmental protection and emission reduction measures must be taken when producing and using carbon raisers to minimize adverse environmental impacts.
