Helong fused magnesia manufacturer origin source company
What does magnesite do; Magnesite is divided into three categories: sintered magnesia, light burned magnesia and fused magnesia. Magnesite is one of the important raw materials for refractories, which is used to manufacture various magnesia bricks, magnesia alumina bricks, ramming materials, furnace repairing materials, etc. Those with more impurities are used to pave the bottom of the steelmaking furnace.

According to the statistics of China Nonferrous Metals Industry Association, 588700 tons of raw magnesium were produced in China from January to July 2017, an increase of 8.42% year on year. The cumulative production in Shaanxi was 276800 tons, up 9.19% year on year; The cumulative production in Ningxia was 100500 tons, a year-on-year increase of 21.47%, and that in Shanxi was 81400 tons, a year-on-year decrease of 2.73%. According to statistical data, from January to July 2017, China exported 283800 tons of various magnesium ingot products, up 29.95% year on year, with a cumulative amount of 654 million yuan, up 26.81% year on year. Among them, 152200 tons of magnesium ingots were exported, a year-on-year increase of 40.13%; Magnesium alloy exports totaled 75100 tons, up 10.83% year on year; A total of 51000 tons of magnesium powder were exported, with a year-on-year increase of 40.22%.

The fused magnesia is made by melting the selected special A grade natural magnesite or high-purity light burned magnesium particles in an electric arc furnace. This product has high purity, large crystal grain, compact structure, strong slag resistance, good thermal shock stability, is an excellent high temperature electrical insulation material, and is also an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and amorphous refractories.

Last week, supported by the continuous tight spot of factories, the magnesium market was running steadily as a whole. As of June 22, 99.9% of the magnesium ingots in Fugu, Shaanxi, reported the mainstream ex factory tax inclusive cash price of 15600~15700 yuan/ton, and the mainstream transaction price of 15600 yuan/ton, which was a lower price source; 15700~15800 yuan/ton in Ningxia and Taiyuan; In Wenxi area, 15900~16000 yuan/ton, which is stable with the price of the previous week, the acceptance price plus 300 yuan/ton, all of which are non pickling and simple packaging prices. The export FOB price is 2500 US dollars~2530 US dollars/ton. Fused magnesia

Thermal conductivity λ= 123.5W/(m · K) (at 100 ℃), decreases with temperature rise. The elastic modulus is 1.96 MPa. The chemical property is stable, and there is no reaction or weak reaction between it and various refractory materials except silica brick at a high temperature of 1500 ℃. The grain size of periclase increases with the increase of calcination temperature and holding time, and the slag resistance is also improved. See the table for the quality requirements of fused magnesia in China.
