Graphitization carburizer indicators should be selected to pay attention to the five indicators

Note 1: It is necessary to look at the content of ash, because more ash will increase the impurities of the steel. It should be controlled below 2% is the best.

Note 2: First of all, we must look at the water content of graphitized carburizer, and water control below 1 is the best. It should be maintained that if more water will enter the molten steel to increase the content of nitrogen in the molten steel, so in the production of storage of graphitized carburizer, attention should be paid to the location of the storage of carburizer, as well as the increase in water caused by the transportation journey.

Note 3: To see the content of fixed carbon, the general graphitized carburizer fixed carbon content of about 95-98.5 is the best.

Note four: Depending on the volatile content, if the volatile content will increase the content of gas in the molten steel. It is best to control the volatile content of graphitized carburizer below 0.7%.

Note five: To see the content of sulfur, sulfur is the most harmful element of the carburizer, the lower the value of the main test sulfur, the more favorable for the graphitized carburizer, the content of graphitized carburizer sulfur ⋅0.06% is the best.
