Semi graphitizedrecarburizer is in the range of 1700-2700℃ calcination furnace insulation,belongs to the medium temperature graphitizing product, high fixed carbon,dissolving speed, high absorption rate, medium sulfur content, nitrogen contentis low, has the high temperature graphitization recarburizer feel is smooth,Nick clear characteristics. It can be widely used in the carburization of graycast iron with high cost performance
The physical and chemical indicators Graphitized (semi - graphitized) petroleum coke | No. | Fixed carbon (Min) | s(Max) | ash(Max) | volatile(Max) | moisture(Max) | N | 1 | 98.50% | 0.05% | 0.7% | 0.7% | 0.5% | 300PPM(Graphitized) | 2 | 98.50% | 0.30% | 0.7% | 0.7% | 0.5% | 500PPM(Semi- graphitized) | Package size | 0-2mm 0.2-1mm 1-5mm 5-12mm Can be customized according to the actual needs of customers The packaging is divided into sub-parent bags (25kg), ton bags, can be customized according to customer requirements | | 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.
