What are the refractory raw material reburned magnesia products?

Re-burned magnesia has refractory properties and is very beneficial to produce refractory products. It is mainly used in the steel industry, glass, cement, and non-ferrous metallurgy industries. It is also a high-quality ideal material for making refractory bricks. 96 Fused Magnesia

From the perspective of historical development, sintered magnesia is also called metallurgical sand, re-burned magnesia, mid-grade magnesia, and high-purity magnesia. In my country, magnesite is used as raw material and processed into light burnt magnesia powder (CCM) through reverberatory furnace, which is large in quantity and widely used. Light-burned magnesia powder is a very important magnesia basic raw material. According to its different chemical composition, particle size and performance, it is used to: calcining various grades of sintered magnesia (DBM), which is different from Al2O3, CaO, etc. The content of the raw materials is to synthesize composite materials such as magnesia-aluminum spinel sand, magnesia-calcium sand, etc., to produce fused magnesia (FM, refractory grade or electrical grade), converter slag splashing and furnace protection magnesium balls. The above products are mainly used as raw materials for refractory products. In addition, these products are also raw materials for magnesium chemical products such as light MgO, light MgCO3, magnesium fertilizer, magnesium building materials, and feed additives.

Traditional light burnt magnesia is processed by roasting raw ore in a reverberatory furnace. The use of reverberatory furnace to produce light-burned magnesia has not been eliminated after 70 to 80 years of survival and development, because the kiln has its outstanding characteristics: simple technology, practical; low investment, quick to start, easy to operate; suitable for southern Liaoning Characteristics of magnesite. In the past ten years, the kiln-type production process has also been greatly improved, which is mainly reflected in: changing to clean fuels, changing the original direct burning of bituminous coal to coal gas produced by a simple gas generator for roasting, avoiding fuel ash content The pollution of light burned magnesia basically solves the environmental pollution caused by black smoke emission and improves the thermal efficiency; the kiln type is modified to increase the volume of the kiln, increase the output, and reduce the fuel consumption.
