The so-called  recarburizer , is to join can effectively improve the content of carbon in liquid iron, so the fixed carbon content of recarburizer must not be too low, or to achieve certain amount of carbon, compared with the addition of high carbon recarburizer more samples need,

Sulfur, nitrogen, hydrogen element low is crucial to prevent produce nitrogen porosity of castings, which requires recarburizer nitrogen content as low as possible.

 

A carbon content of high black or grey particles ( or block )product, added to the metal smelting furnace, increasing the carbon content of molten iron, one can reduce the oxygen content of molten iron, on the other hand, more important is to improve the mechanical properties of metal smelting or casting.

Many sources, carburant shapes, according to its processing technology and components of different, the price difference is very great. Smelting method similar to conventional Cupola Melting: the use of pig iron, scrap, steel scrap, iron alloy such as metal charge; synthetic cast iron production process: the use of new scrap charge, using carbon to carbon equivalent adjustment of molten iron. After a mode of production is easy to ensure high quality iron liquid, at the same time by using less or replace to greatly reduce the cost of pig iron scrap. Popular to say, by carbon agent, we can use the worst ( scrap ) make the best ( casting).
