Carbon Raiser

Description

Description of Carbon Raiser:

In order to make up for the carbon content in the iron and steel smelting process due to factors such as smelting time, holding time, and long overheating time, the carbon-containing substances added are called carbon raiser.
There are many types of carbon raiser, which can be generally divided into metallurgical coke carbon raiser, calcined coal carbon raiser, petroleum coke carbon raiser, graphitizing carbon raiser, natural graphite carbon raiser, and composite carbon raiser. Graphitization can reduce the content of impurities in the carbon raiser, increase the carbon content of the carbon raiser, and reduce the sulfur content. When casting, it can greatly increase the amount of scrap steel, reduce the amount of pig iron and even no pig iron. Therefore, graphitized carbon raiser is the high-quality carbon raiser.

Technical Parameter of Carbon Raiser:

Category	C %	S %	Application
Metallurgical Coke Carbon Raiser	＜85%	≈1%	Recarburization in large coke in cupola,   metal charge
Calcined Coal Carbon Raiser	90~93%	0.3~0.5%	Steel-making, gray iron
Petroleum Coke Carbon Raiser	96~99%	0.3~0.7%	Steel-making, grey iron, brake pads and cored wires, etc.
Graphitization Carbon Raiser	98~99.5%	0.03~0.05%	Nodular cast iron
Natural Graphite Carbon Raiser	65~99%	-	Steel-making
Composite Material Carbon Raiser	93~97%	0.09~0.7%	Temporarily unable to stabilize the addition and sulfur content.
