Industrial refractory grade magnesium oxide powder manufacturer
Dead Burned Magnesite (also known as Dead Burnt Magnesite)
Dead burned magnesite is widely used as a basic refractory material. It is produced in rotary kilns and has purities of 90-97% MgO. It is widely used for gunning/ramming mass for tundish linings and for fettling purposes. Dead burned magnesite can be supplied in lump for users to crush and grade, or in ready-sized form. Common sizings are 5-3mm, 3-1mm, -1mm, -0.5mm and DIN 70.
Magnesite at 1800 ℃ calcination, carbon dioxide completely escape, magnesium oxide periclase formed dense block, weighing burning magnesium (also called sintered magnesite), the dead-burned magnesium has the very high refractoriness. Its main ingredients for magnesium oxide, select natural super magnesite writing flotation purification, light burned, fine grinding, high pressure ball, ultra high temperature oil shaft kiln calcine.
