Benefits of Carbon Raiser
Improve production efficiency and quality
Carburizer has the characteristics of high absorption rate, low sulfur and low nitrogen, and can improve the quality of smelted metals and castings. Its porous structure, easy melting and fast absorption also help improve production speed and product quality.
Environmental protection and energy saving
The carburizing agent has a strong deoxidizing effect, which can reduce the amount of slag produced and make the slag removal operation easier. In addition, the use of carburizer can extend the service life of the furnace wall and reduce equipment maintenance costs.
Reducing costs
The use of carburizing agents can greatly increase the use of scrap steel, reduce the use of pig iron or eliminate the need for pig iron, thereby reducing production costs. In addition, the carburizing agent is of high quality and low price, which can reduce the amount of spheroidizing agent added and further reduce the cost of molten iron.
Improve metal properties
The use of carburizer can reduce white spots, significantly improve machinability, and improve mechanical properties. It also reduces wall thickness sensitivity and makes the cutting surface smoother.
Types of Carbon Raiser
Calcined anthracite coal
The raw material of the anthracite recarburizer is anthracite, which went through dry distillation at 1300°C to reduce volatile matter and increase the solid carbon content.
Calcined petroleum coke
Calcined petroleum coke is the most suitable carbon raiser for steel making. The raw material is raw coke, which contains high impurities and cannot be used as a carbon additive. The carbon additive is obtained after high-temperature calcination of petroleum coke. After the petroleum coke is calcined at a high temperature of 1200-1400℃, most of the moisture and volatiles, and other impurities are removed. The carbon content is as high as 98.5%. The carbon additive is irregularly shaped carbon particles with metallic luster and more transparent carbon particle pores. The high quality of calcined petroleum coke is mainly dependent on the low content of sulfur which finally affects the quality of steel.
Graphite petroleum Coke
The raw material of graphite carbon additive is also green coke, but the calcination temperature ratio is 3000. The degree of carbon fixation is high, and the content of S, N, and P is much lower than that of coal. Graphite carbon additive is mainly used for ductile iron with the characteristic of quick absorption, high carbon, and low sulfur.
Application of Carbon Raiser
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.
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.
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.
Machinery manufacturing
As a lubricant and wear-resistant material, it can improve the wear resistance, performance and life of mechanical parts.
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.
