How to use recarburizer for foundry

The furnaces for casting recarburizers include heating furnaces, aluminum melting furnaces, intermediate frequency furnaces, high frequency induction furnaces, etc., so that the amount of waste steel can be greatly used during application, reducing the use of cast iron or eliminating the need for cast iron. The recarburizing agent is targeted at castings. There is a great assistance in manufacturing.

Sales market of recarburizer for foundry

The use of recarburizers has always been a topic of concern to everyone in the sales market. After the baptism of the body and mind of the sales market, the types of recarburizers are also continuous. Many foundry ironmaking companies also have a large number of choices, which are aimed at recarburization. The development trend of the agent sales market is also important. Naturally the two are closely related.

Recarburizer furnace for foundry

Furnaces that use recarburizers include heating furnaces, aluminum melting furnaces, intermediate frequency furnaces, high-frequency induction furnaces, etc., so that the amount of waste steel can be greatly used during application, and the use of cast iron can be reduced or cast iron is not required.

The recarburizer is indeed very helpful for the production of castings. For pig iron (gray cast iron, ductile cast iron, vermicular graphite cast iron, gray cast iron, white pig iron, etc.), the graphite in the graphite recarburizer can be used as a pre-eutectic The nucleus of graphite and eutectic graphite. Castings are different, and the types of recarburizers are also different. From the perspective of cost, selecting a suitable recarburizer will greatly assist the quality of the casting and its economic benefits. In addition, studies have shown that the use of carbonaceous recarburizers with different seasoning ratios and the absence of recarburization processing technology, under the same standard of final iron content, the nitrogen content in pig iron that has undergone recarburization is resolved. The produced boron nitride, etc., can be used as a key substrate for graphite crystals, creating an excellent development standard for the composition of graphite. And then the quality of castings.

Method of operation

Under normal circumstances, the recarburizers are all promoted together with the recycled waste materials such as waste steel. The dosage can be selected and added to the surface of the molten steel, and it can also be added in batch number quantitative analysis. (Common problem: It is necessary to prevent a large amount of material being added to the molten steel to avoid excessive air oxidation and the actual effect of carbon increase is not significant and the casting damage is more serious.)

What should be paid attention to when applying recarburizers in casting is to choose the amount of recarburizers added according to different furnace sizes and furnace temperatures. Different types of pig iron are selected according to different models and specifications of recarburizers. The content of recarburizers on the sales market is more from 75-98.5. With the regulation of product quality in the sales market, the recarburizer sales market is also fluctuating, which is a crucial step in the selection of graphitized recarburizers. Therefore, the choice of recarburizer for casting is also very good.
