Black Carborundum silicon carbide is an ideal compound deoxidizer, desulfurizer.ca and have a strong affinity with oxygen. Especially calcium, not only has a strong affinity with oxygen, and sulfur, nitrogen has a very strong affinity.
Black Carborundum is also suitable for practicing BOF steel plant with a warming agent, also used for cast iron and ductile iron inoculant production of addictives.
We are professional black carborundum manufacturer for customers in different industries and countries according to FEPA, JIS, GB, ISO, ANSI & P standard. 0-1mm, 1-3, 3-5mm etc. for refractoriness, FEPA F sizes for bonded abrasives aluminum oxide tools, FEPA P sizes for coated abrasives silicon carbide products.
