Forsterite Product Brief

One, product characteristics

My company produces magnesium olivine sand, refractory degrees up to 1750 degrees C, good thermal stability, high temperature and small volume expansion, good thermal shock resistance, and high temperature strength, good abrasion resistance. Because the ore calcium content is low ( less than 1% ), the production of magnesium olivine sand performance is stable, not easy to fly, in high manganese steel casting, its effect is superior to the traditional sand casting, in coatings is also successful trial production, a variety of refractory products, its quality has been associated with similar foreign technical indicators, and energy conservation in the only significant superiority, has a good utilization prospect.

In two, the main purposes

Magnesium olivine are widely used in metallurgical materials, high manganese steel casting sand, refractory materials, special materials and magnesium fertilizer raw materials. As the metallurgical solvent, slag modifier, iron making sinter additive, can improve the quality of products. Its products are used in ladle, tundish, blast furnace trough, can improve the service life of lining, reduce consumption of refractory material, also can be used as a heat insulation plate, slag wall materials, is currently used for steelmaking drainage sand, refractory material molding sand for casting, wear-resistant materials of high quality raw materials. The company production of magnesium olive sand is especially suitable for high manganese steel, alloy steel casting, casting surface smooth, clear, precise size, stained sand sand, no free SiO2, can effectively prevent silicosis. Magnesium olivine has very high load softening degree, have a stronger resistance to molten iron oxide action ability, can be used for making silica brick, processing of the heating furnace and a variety of industrial heat storage chamber grid and other products, excellent performance and can be widely used for casting material, spray material is qualitative fireproof material.
