casting iron foundry graphite / petcoke calcined petroleum coke

High carbon content low sulfur calcined petroleum coke is made of calcined petroleum coke as raw material, then going through fully graphitization of the continuous graphitization process under the high temperature of minimum 2600℃ . Afterwards, through crushing, screening and classification, we supply our users with the different particle size between 0-50mm at the customers' request.

 Acting as the inoculant and carburizer, it's widely used in the special steel smelting and precision casting process, especially meeting the requirement of high quality product and strict control of sulfur content in the ductile iron and grey iron casting industry. lt's also used as reducer agent in the nuclear reactor, the absorbent of heavy metal in the waste water treatment system and the raw material of graphite cathode in the aluminum electrolysis cell.

Furnace input method:
suitable for use in an induction furnace melting,using a slightly different method according to the specific process requirements of each unit.

(1) Intermediate frequency electric furnace smelting,can add into the furnace in the lower part according to the ratio of carbon equivalent requirements or material with the recovery rate up to 95%.

(2)After melting is completed,if the carbon content isn’t enough that needs to adjust, first remove furnace slag,then add carbon agent, through heating up of molten iron by electromagnetic stirring or artificial stirring to dissolve the carbon to be absorbed with the recovery up to 90%.If apply low temperature carbon growth process,that only part of charge is melted with lower melting temperature of molten iron,then add all recarburizer in liquid iron, also with a solid charge pressed it into liquid iron do not let it exposed on the surface.In this method it can reach more than 1.0% carbon of iron liquid. 

Furnace output method:

(1) Graphite spray in package: use graphite to be carbon agent, blowing amount of 40kg / t, is expected to make the carbon content of the molten iron increased from 2% to 3%. As the carbon content of the molten iron is gradually increased, the amount of carbon utilization fell.Carbon increased by graphite spray,typically using nitrogen as a carrier, but under industrial conditions, using compressed air is more convenient, and oxygen in the combustion air burning produce CO,the chemical reaction heat can compensate for part of the temperature drop,and CO in reducing atmosphere is conducive to improve the effect of carbonization.

(2) Increase the carbon when iron is poured out:100-300 mesh of graphite powder can be placed inside the package,or into the tank with the flow of the iron,it should be completely stirred to make carbon dissolved and absorbed as much as possible after the iron liquid was poured out,and carbon recycling rate is about 60%.
