High temperaturegraphitization recarburizer is in the center of the calcined furnace area ofabout 3000 ℃ calcination, long time graphitization completely, high fixedcarbon, low gas content of impurities, dissolved rapidly, high absorption rate,it is first choice of ductile cast iron increases carbon.

Method of use 1.induction furnacemelting:if the electric furnace volum belows 2 tons, the first melting infurnace, pad with a small amount of iron filings the bottom of furnace first, add allcarburizer in one time, then add metal charge melting successively; In normalmelting, a small amount of molten iron is left in the furnace. When three tonsor more volum electric furnace is melting, carburant is added in two times,about half of which is added to the bottom of the electric furnace, and therest is added in half of the charge. 2.induction furnace ironcarburizing: choose small particle size, melting speed of the carburizing agentadded to the surface of the molten iron, the use of electromagnetic stirringeffect fully melting, and then slag scraping.
