Introduction of recarburizer
Steelmaking recarburizer (ferrous metallurgy industry standard of
the People\'s Republic of China, YB/T *******1 steel using
recarburizer) and cast iron using recarburizer, adding material and
some other useful also to carburant, such as brake pads with
additives, friction material.Recarburizer belongs to plus
steelmaking, ironmaking increase carbon materials.High quality
recarburizer is essential for production of high quality steel
auxiliary additives.
There are many kinds of raw materials about carburant, production
process is also different, woodiness carbon, carbon coal, coke,
graphite, such as, among them under various classification and
there are a lot of small type.High quality recarburizer generally
refers to after graphitization of carburant, under the condition of
high temperature, carbon atoms arranged in the microstructure of
graphite, so called the graphitization.Graphitization can lower the
content of impurities in the carburant, improve the carbon content
of carburant,and reduce sulfur content.
Recarburizer used in casting, can greatly increase the dosage of
scrap steel, reduce the dosage of pig iron or no iron.Electric
furnace smelting way of feeding, recarburizer with scrap steel
should be burden to put together, such as small doses of adding can
choose to add in the hot metal surface.But want to avoid mass
feeding into the molten iron, in order to prevent excessive
oxidation by carbonization effect is not obvious and the carbon
content of the casting is not enough.Increased carbon agent, the
dosage according to the ratio of other raw materials and carbon
content.Different kinds of cast iron, according to need to choose
different types of recarburizer.Choose recarburizer characteristics
itself pure carbon graphite material, reduce too much impurity in
the iron, carburant choose appropriate which can reduce the cost of
castings.
Carbon additive for casting,which made from high quality carbon
material ,its including normal cast iron, spheroidal graphite
iron,our carbon additive has the advantages of increasing the use
of waste steel, lower even non-use of the raw iron material, it can
be well absorbed in the ironing liquid and no dreg , can cut down
cost of casting.
This product mainaly used in steelmaking in eletrical stove,
shipbuilding sandblast removing rust producing carbon materials
