From a refractory bricks manufacturing factory, Changxing has become a professional manufacturer with various refractory materials and oil fracturing proppant both in domestic and international market during 30+ years, whose customers covers North America, Middle East, Asia, Africa, etc.
Stuffing sand is an necessary refractory material for electric furnace taphole. Mainly made by magnesium olivine sand and fuse magnesite as raw material, adding the carbon material as additives, composite according to the specially appointed grain size and weight percent. Finally mixing them and produce filling sand. After testing , it is proved that it has good dispersion and mobility,high refractoriness, no sintering, no clogging. Also the tapping drainage rate is more than 100% and the service temperature is more than 1750 ℃。 It won’t react with molten steel and alloy composition. Storage quality does not change. So it can satisfy steel making process requirements and is the most Ideal refractory material for eccentric furnace steelmaking.
Changxing has a production line, which is base on oil & gas applied ceramic proppant, and also with 3 factories focusing on all kinds of refractory materials used for iron & steel casting, cement, glass petrochemical and ceramics industries. With abundant sources and professional techniques, Changxing Refractory would like to build a reliable and efficient platform for customers all over the world.
