why is carburizer added during steelmaking

There are two main reasons for including carbureizers in the steelmaking process. First, carburizers are used to achieve the required carbon content in the steel. Secondly, they improve the overall efficiency of the steelmaking process.

Carburizers are substances characterized by a high carbon content. Their inclusion in the steelmaking process makes it possible to increase the carbon content of molten steel. During the steelmaking process, the carbon content of molten steel can decrease due to oxidation, so the addition of carburizers effectively compensates for this decrease. In the case of high-carbon steels, such as tool steels and bearings, there are strict requirements for carbon content, which requires the addition of carburizers to meet these requirements.

Secondly, carburizers can improve the efficiency of the steelmaking process. During the steel manufacturing process, carburizers react with the oxygen present in the molten iron and form carbon monoxide, which subsequently reduces the oxygen content of the molten iron. This reaction facilitates the oxidation process of molten iron and increases the oxidation rate, thereby improving the overall efficiency of steelmaking.

In addition, carburizers play an important role in improving the quality of steel. Due to their inherent properties, including high carbon content and low sulfur and phosphorus content, carbureizers effectively reduce the concentration of sulfur and phosphorus in steel. This reduction contributes to an increase in the overall purity and quality of the steel. In addition, carburizers increase the hardness and wear resistance of steel, making them widely used in the production of high-strength and wear-resistant mechanical components.
