| Model Number: DLCHEM-606 Place of Origin: China 1. Magnesite ore: This is coarse crystalline natural raw magnesite (also called macro-crystalline magnesite) which is almost a natural ore constituted wholly by magnesium carbonates(MgCO3). It is of a rhombohedral crystal structure; often an aggregate of dense lump; more in white or gray color with glass glance; hardness 3.4-5; specific gravity 2.9 - 3.1; and high purity. It is mainly used in the manufacture of refractories and the extraction of magnesium metal. Besides, it is also used in the industries of cement, rubber, paper, sugar, chemical and building materials. 2. Dead burned magnesite: Dead burned magnesite is selected from natural magnesite, produced by mine selecting, purifying, and calcining in shaft kilns. It is an ideal material for unshaped refectory material. The final products are used in opening hearth furnace, electric furnace bottom furnace and lining tamping. 3. Middle grade dead burned magnesite: The products are made from sorted natural raw magnesite through sintering in high temperature shaft kilns. They are ideal materials for making monolithic refractories. Their finished products are also used for making the bottoms or lining of open hearth furnace and electric arc furnace. 4. High purity dead burned magnesite: The products are made from sorted super grade natural magnesite through sections including float concentration, calcination, fine granding, high pressure briqueting and ultra high temperature sintering in heavy oil shaft kilns. They are good quality materials for making magnesia bricks and monolithic refractories. 5. Electro-fused magnesite: The material of electro-fused magnesite sinter is selected from high-grade magnesite or high purity caustics calcined magnesite, which is fused in arc furnace to finish the products. The products possess high purity, high crystalline grain and compact texture, have high heat-vibration steady and cinder corrosion resistant. It is widely used in making high quality magnesite bricks, magnesia-carbon and bricks and unshaped refractory materials. Packing: 1,000kg/jumbo bag, or according to customers' requirements Dalian Chem Imp. & Exp. Group Co., Ltd.
