Hebei Messi Biology Co., Ltd. stated that with the increase in China’s electrical steel production, the demand for silicon steel grade magnesium oxide has continued to increase, and the traditional process of preparing magnesium oxide using dolomite as raw material can no longer meet market demand. China is a country rich in brine resources, so it is becoming increasingly important to study how to comprehensively utilize salt lake resources.
Silicon steel grade magnesium oxide is a coating material for preparing oriented silicon steel. It is mainly used in the high-temperature annealing stage of oriented silicon steel, and plays the role of isolation agent, insulating film layer, desulfurization, dephosphorization, etc. Hebei Meixi Biological Co., Ltd. has counted the methods, process flow, research progress and existing problems for preparing silicon steel grade magnesium oxide, pointed out the development direction of silicon steel grade magnesium oxide preparation technology, and put forward suggestions for the utilization of China’s brine resources.
Silicon steel grade magnesium oxide is a magnesium oxide coating material used to manufacture oriented silicon steel sheets. It is a high value-added magnesium oxide product. It is mainly used in the high-temperature annealing stage of the manufacturing process of oriented silicon steel sheets. It plays the role of isolation agent, dephosphorization, and desulfurization agent. At the same time, it reacts with silicon on the surface of silicon steel to form an excellent insulating film layer. Silicon steel grade magnesium oxide can also be used to make refractory crucibles, precision ceramics, special polishing agents, and can also be used in the aerospace industry, electronics industry, etc. In 2020, the domestic demand for silicon steel grade high-purity magnesium oxide is 100,000 tons, while the domestic output is about 1,000 tons, which is far from meeting the needs of enterprises. The market potential of silicon steel grade magnesium oxide is huge, and it is necessary to strengthen the research on the preparation technology of silicon steel grade magnesium oxide.
