Casting Recarburizer Application

Casting Recarburizer agent is mainly used in the production of castings. It plays a different role in the use of different castings. In the case of steel casting and steelmaking, the most commonly used is coal-based Recarburizer agent, which has a relatively high absorption rate and high-quality Recarburizer. Additives are essential auxiliary additives for the production of high-quality steel castings.

1. Graphite-based high-carbon and low-sulfur products are generally used as the nodular iron Recarburizer agent. The basic requirements are: C> 98.5 S <0.05; its main materials are graphitized petroleum coke, graphitized electrodes, and so on. It also has the highest absorption rate and the fastest absorption time among Recarburizer agents.

2. The difference between the main technical indicators of gray iron carburant and ductile iron carburant lies in the control of sulfur. The general index requirement is S <0.5, and the C content can be selected according to the cost control requirements 98.5 95 93 90 and so on. The absorption rate of this type of recarburizer is generally around 85%. Its main materials are non-graphitizable petroleum coke, calcined coal, etc.

3. For cast steel and steelmaking, the most commonly used is the coal Recarburizer agent, which has a relatively high absorption rate.

4. For special castings, such as the production of brake pads, petroleum coke recarburizer is used a little more, and the absorption rate is more than 80%.

5. The type of Recarburizer agent for cast steel (steelmaking) is relatively complicated. Generally, large steel mills will choose a variety of Recarburizer agents according to different steel types. . The content ranges from 75-99.
