At present, the process method of producing fused magnesia is generally to use electric furnace for smelting and directly smelting magnesium ore. The disadvantage is that the power consumption is large. In addition, 80 kg of carbon rod is required for each ton of qualified fused magnesia (96.5%) smelted with the existing process. Relevant data (Special Refractories, Magnesia Technology, and High Temperature Refractories Collection) show that, The light magnesia can be heated by electric arc to form cubic crystal, that is, heavy magnesium oxide with a melting point of 2800 ℃, that is, fused magnesia. The fused magnesia can be produced by recrystallizing the magnesia produced by furnace smelting in electric furnace.

What are the main contents of magnesia? The medium grade magnesia mainly contains 94% and 95%. The medium grade magnesia is produced from light burned magnesia with 97% MgO as raw material through ball pressing, high-temperature shaft kiln calcination and other processes. The product has good sintering degree and dense crystallization. It is a high-quality raw material for producing medium grade magnesia refractory products.

The magnesium oxide extracted from seawater is called seawater 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.

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

Magnesite is calcined at high temperature from magnesite, bischofite or magnesium hydroxide extracted from seawater. It is a general term for the products of magnesite and other magnesia raw materials that have been treated at high temperature to reach the sintering process. Magnesite sintered from natural magnesite is made by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln; Seawater magnesia is produced by extracting magnesium oxide from seawater after magnesite and other raw materials are melted in an electric arc furnace and cooled.
