Product Description

Application advantages

1. Efficient carbon increase: high fixed carbon content, easy to dissolve in molten iron, fast carbon absorption speed and high absorption rate, can significantly increase the carbon content in molten iron, stabilize the carbon increase effect, and provide a stable and reliable carbon source for cast iron.

2. Reduce costs: The use of this product can greatly increase the amount of scrap steel, reduce the use of primary iron, or even eliminate the need for pig iron, thereby effectively reducing the production cost of castings and improving the economic benefits of enterprises.

3. Improve the quality of castings: It can reduce the number of shrinkage holes and pores in castings, improve the overall quality and reliability of castings, and produce castings with high surface finish and stable dimensional accuracy, meeting the requirements of various precision castings.

Product features

1. High purity: After a special calcination process, the carbon content of this product is as high as 95% or more, and the impurity content is extremely low, which can effectively reduce defects such as pores and sand holes in castings, and improve the density and purity of castings.

2. Suitable particle size: The particle size design of 80-150mm ensures full contact with the molten iron when smelting cast iron in an induction furnace, and will not be oxidized or carried away by the airflow due to the small particles, ensuring the efficient and stable carbon increase process. It has a long reaction time with the metal in the furnace, can be fully dissolved, and improve the carbon increase efficiency.

3. Good physical properties: This product has high hardness and wear resistance, giving the casting better durability; at the same time, its high thermal conductivity helps the casting to quickly dissipate heat during the solidification process, optimizes the cooling performance and microstructure of the casting, and improves the comprehensive mechanical properties of the casting.
