Its products can be divided into metallurgy magnesite and magnesia products into two categories. Depending on the chemical composition and use can be divided metallurgical magnesia brick, brick magnesium, Mg-Al brick, brick, magnesium, calcium, carbon brick, and other varieties. Its performance is greatly affected by CaO / SiO2 ratio and impurities. High Purity Magnesia load softening point and thermal shock resistance are much higher than the general brick as well. High refractoriness refractory variety of basic slag and iron slag has good resistance, is an important high-grade refractory (Refractory material). Sintered magnesia products multi-brand production of refractories, the firing temperature is generally between 1500 ~ 1800 ℃ refractories, in addition, you can also add a chemical binder made of unfired brick and monolithic refractories (Refractory material). Mainly used for open-hearth, electric furnace, oxidation converter, nonferrous metal smelting furnaces, kilns, and basic refractories (basic refractory) calcining kiln. Secondly, used in the manufacture of steam boilers, furnace smelting furnace windows and machinery. Basic refractory bricks and can be processed into a siliceous products, can also perform a variety of low-cost acidic refractory material, uniform thickness of the insulating material. Physical characteristics: Refractories is a layered water containing silicate minerals, many types of basic refractories has a unique acid, alkali, chemical stability, but also has good insulation and heat resistance, non-flammable, corrosion protection.
