Product description

Graphitized recarburizers generally refer to graphitized recarburizers. Under high temperature conditions, the arrangement of carbon atoms is in the microscopic shape of graphite, so it is called graphitization. Graphitization can reduce the content of magazines in the recarburizer, increase the carbon content of the recarburizer, and reduce the sulfur content. 
The use of recarburizers in casting can greatly increase the amount of scrap steel and reduce the amount of pig iron or do not use pig iron. Most of the recarburizers are suitable for electric furnace smelting, and a small number of recarburizers with particularly fast absorption are used in cupola furnaces. In the feeding method of electric furnace smelting, the recarburizer should be put in together with the charge such as scrap steel, and a small dose can be added on the surface of molten iron. However, it is necessary to avoid feeding molten iron in large quantities, so as to prevent excessive oxidation, resulting in insignificant carbon increase effect and insufficient carbon content in castings. The amount of recarburizer added is determined according to the ratio of other raw materials and the carbon content. Different types of cast iron, choose different types of recarburizers according to your needs. The characteristics of recarburizer itself choose pure carbon-containing graphitized substances to reduce excessive impurities in pig iron. The proper selection of recarburizer can reduce the production cost of castings.

Features

1. High fixed carbon, high absorption rate, low sulfur and low nitrogen, and the absorption speed is faster than that of similar graphitized recarburizers, and does not adsorb the furnace wall, completely absorbs no residue, and the price is lower than the same kind of sulfur below 0.05 Graphitized recarburizer, cost-effective.     
2. High absorption rate, according to the method of use, the absorption rate can reach more than 90%;
3. The absorption speed is fast, which is faster than that of similar graphitized recarburizers, does not adsorb the furnace wall, and has no residue, and the advantage of carbon increase absorption speed in the furnace is more obvious;
4. Low sulfur content, below 0.05%, low nitrogen content, below 100ppm;

5.Ultra-high cost performance, summarizing the above-mentioned price advantages in similar graphitized recarburizers (sulfur ≤ 0.05). 
6. Benefit impact: Graphite recarburizer reduces costs and improves product quality for you;

7. The raw material can increase the amount of scrap steel, reduce the amount of pig iron or do not use pig iron, which can effectively avoid the influence of the heredity of pig iron on castings;

8. Low sulfur content, stable and reliable, effectively saving the adverse effect of sulfur on the alloy in the process of spheroidization and inoculation, and saving the cost of the alloy;
9. Due to the low melting point, fast absorption and no anti-slag, it can effectively protect and prolong the furnace age and reduce the consumption of the furnace lining;

10. Pure chemical composition: high carbon, low sulfur, slight nitrogen, less harmful impurities;
