carburizer in casting

The use of carburizer during casting is now the mainstream method. Since most carburizing agents are suitable for electric furnaces, the feeding method of electric furnaces is generally to put scraps and other raw materials together with carburizing agents.

 

Put the cast steel carburant along with the scrap steel and other furnace materials. Small amounts can be added to the surface of the molten iron. However, it is necessary to avoid large quantities of molten iron into the molten iron to prevent excessive oxidation. The carbonization effect is not obvious and the casting Insufficient carbon content.

Of course, the carburizer manufacturers can also add a small amount of cast steel carburizer on the surface of the molten iron. In order to prevent the over-oxidation and the inadequate spring effect and the insufficient content of the casting, a large amount of net molten iron should be prohibited. As for Don't worry about how much you join, let's look down.

The added amount of cast steel carburant should be determined according to the ratio of other raw materials and carbon content. According to the needs of different cast irons, select the appropriate type of carburizer. The characteristics of the carbon agent itself select pure carbon-containing graphitized substances to reduce Too many impurities in the pig iron, the choice of suitable carbon enhancer can reduce the production cost of castings.
