Product Introduction
What is the Recarburizer ?
Recarburizer , another name is carbon additive , carbon raiser . Main purpose is to increasing the carbon element in steel making and casting . There are many kinds of Recarburizer , so different steel mill and foundry choose it depends on demand . Main kinds are Synthetic graphite recarburizer,Petroleum coke recarburizer, Calcined coal recarburizer.
How to produce Recarburizer/Carbon raiser ?
1.Synthetic graphite recarburizer.
The main raw material for the manufacture of artificial graphite is fine calcined petroleum coke in powder form.After all kinds of raw materials are well matched, they are pressed into shape and then treated at 2500 ~ 3000℃ in a non-oxidizing atmosphere to make them graphitized.After high temperature treatment, ash, sulfur and gas content were greatly reduced.
Due to the high price of artificial graphite products, the commonly used artificial graphite carbonizing agents in foundry are mostly recycled materials such as chips, waste electrodes and graphite blocks when making graphite electrodes, so as to reduce the production cost.
In smelting nodular cast iron, artificial graphite is the first choice for carbonizing agent

2.Petroleum coke recarburizer
Petroleum coke is a by-product of refined crude oil. The residual oil and petroleum bitumen obtained from crude oil often by pressure distillation or vacuum distillation can be used as raw materials for manufacturing petroleum coke. After coking, raw petroleum coke can be obtained.

3.Calcined coal recarburizer
Calcined coal recarburizer is made of coal powder , according to customer requirement , we select different element of coal powder to process Calcined coal recarburizer .

Usage :
Used for casting, cast iron, cast steel, cast will have a requirement for carbon, carburant just as its name implies is to increase the carbon content in liquid iron, and, for example, commonly used in smelting furnace charge for pig iron, scrap steel, back to the furnace charge, iron carbon content is high, but relatively scrap purchase price is higher section, so adding scrap supply, reduce the quantity of pig iron, increase carbon agent, can reduce the casting cost play a role.
The use of carbonizing agent can not only make up for the loss of carbon in the process of steel smelting and ensure the carbon content of specific steel brands, but also be used for after-furnace adjustment.
As an important raw material for melting molten iron in induction furnace, the quality and usage of carbonizer directly affect the state of molten iron
The carbon content in the ladle can be adjusted by adding a specific brand of carbonizing agent to the ladle after slag removal and gas removal.The main materials used for carbonizing agent are graphite, graphite, electrode block, coke, silicon carbide and other materials.The commonly used electrode block and silicon carbide carbonizer have the advantages of high carbon content and strong oxidation resistance.The production cost of coke powder and graphite is lower than that of electrode block, but the ash and sulfur content are higher and the carbon content is lower.
