Naturally, in China, various carburizers are also gradually integrated, which are very high nitrogen carburizing agents which involve forging cost are also widely used, such as poor graphitization of petroleum coke and fat coal. Carburetor dealers emphasize that experience must be accumulated in the future. For the carbon with poor graphitization, the addition of steel-making furnace is low digestion (only 40-60%), second, the digestion rate is slow, and the third is the sediment caused in the furnace. It is very easy to make the hot metal nitrogen composition exceed the standard, resulting in the pore like nitrogen. Sometimes there is no stomatal defect, and the reason will be related to the titanium in molten iron and nitrogen with strong infective factors. I hope you can notice this and learn from it gradually.
The way of adding carburizing agent is to add a lot of nitriding agent in the production of pig iron, which can be added with waste steel and carbon carbon composite material in the early or middle and late stage of heating furnace smelter. The carburizing agent factory thinks that it involves the addition in the middle and later stage of the smelter, which has the effect of preparation treatment and improves the effect of high-purity graphite core. At this time, be sure to add carbon preservative with low nitrogen content, and the amount should not be too much, not more than 0.2%, to prevent high-purity graphite from thickening. With the addition of carbon agent, the ideal temperature of the steel-making furnace is about 1500 degrees, and the liquid level meter of the purification tower is cleaned. After more than ten minutes, the temperature can get rid of the electric oven. If you don't pay attention to the liquid level meter, you can't digest and absorb the residual carbon agent, because it is in the whole process of mixing the molten iron hazards, and it can also give full play to the vaccine.
