Carbon raiser uses
1. Compensate the carbon content lost during the steel smelting process and increase the carbon content in the molten iron.
2. Improve the mechanical properties such as tensile strength, hardness, wear resistance and fatigue limit of castings.
3. Improve the distribution of carbon and alloy elements in cast metal, making the structure in the casting dense and uniform in composition.
4. Reduce the amount of slag generated, simplify slag removal operations, and improve casting efficiency.
5. Improve the fluidity of molten metal and stabilize the composition of molten iron.
Types
- Petroleum coke carbon raiser
It is processed by calcining and purifying petroleum coke and has a round or polygonal appearance. It is an ideal carbon-added material and reaction intermediate in metallurgy, chemical industry, machinery, electric power and other industries, and is widely used.
They can usually be used in cupola furnaces. In addition to smelting, its role is also studied as carbon is used as different metal charges.
Its general composition is c90-93%, s0.3-0.5%. Mainly used by 製鋼 enterprises.
- Graphitized carbon raiser
The main materials are graphitized petroleum coke and 黒鉛電極. And the general composition is carbon content 98-99.5%; sulfur 0.05-0.03%. It is characterized by fast absorption, high carbon content and low sulfur content. It is mainly used in ductile iron.
Mainly natural graphite, with a carbon content of 65%-99%. It is mainly used in steel mills, not foundries.
Industrial Applications
1. Steelmaking industry: Using carburizers as additives can effectively increase the carbon content in molten steel and improve the physical and mechanical properties of steel. To obtain steel with excellent performance.
2. Casting industry: The carbon content of the original smelting metal raw materials is often low. They can effectively increase the carbon content of castings, improve their organizational structure and mechanical properties. Enhance the mechanical strength and wear resistance of castings.
3. Smelting industry: During the smelting process, the use of carburizers can effectively reduce the impurity content and improve the fluidity of the flux. At the same time, it can also improve the production efficiency of the smelting process and reduce energy consumption.
4. Machinery manufacturing: As a lubricant and wear-resistant material, it can improve the wear resistance, performance and life of mechanical parts.
5. Aerospace industry: The carbon materials produced with it have excellent properties of high strength, high conductivity and high temperature stability, so they are widely used.
