various type carbon raiser

Carbon raiser is also be called recarburizer, carbon additive, carbon, etc, it is one type of product with the main content of carbon, the carbon content can reach 85%,90%,95% even 98%, for different raw materials can be divided into different types such as calcined coal, calcined petroleum coke, graphite carbon, graphitized petroleum coke etc.

The carbon raiser is always be used in the steel-making or casting to increase the carbon content, at present, because of the pig iron price rising and rising, so much more manufacturers adopt the steel or iron scrap as raw materials, and such materials include almost no carbon, so make the carbon additive material much popular.

These days influence by COVID-19, the price of CPC,GPC is higher and higher, and what is more, the price rising of the sea cost make the export of such materials more difficult, there is one type of new carbon raiser, which is shaped from graphite carbon powder to the columnar, the carbon content of such product can reach 90%,95%, what is more important the content of nitrogen can reach 800PPM, and the sulfur can reach 0.08% or even low. Compared with CPC, GPC, the price of graphite carbon columnar is much competitive, since 14th, April,2021, the quotation of CPC (carbon 98%, sulfur 0.5%, size 1-5mm) is 780USD/T, and GPC (carbon 98%, sulfur 0.05%, size 1-5mm) is 866USD/T, but the quotation of columnar graphite carbon will be just 566USD/T.

Generally speaking, the CPC is always be used for the gray iron casting, and the GPC carbon raiser can be used for gray iron and ductile iron casting because of the content of nitrogen, for the columnar graphite carbon, because of the content of nitrogen and sulfur is also low, so for the steelmaking and casting are both suitable, and for the 750kg furnace or bigger are all suitable, the absorption rate can reach 80% or higher.
