Hebei Messi Biology Co., Ltd. stated that silicon steel grade magnesium oxide can improve the insulation performance of silicon steel sheets, can be used as a high temperature annealing isolation agent, can also be used to make ceramic materials and electronic materials, and is used as a dephosphorization agent, desulfurization agent, and insulating coating generator in silicon steel production. At present, there are two main routes for producing silicon steel grade magnesium oxide internationally. One is to use magnesium oxide prepared from magnesium hydroxide as raw material, and the other is to use magnesium oxide prepared from magnesium carbonate as raw material.
Israel uses magnesium chloride to spray calcined under high temperature conditions to decompose into magnesium oxide and hydrogen chloride with a content of about 80%. The obtained magnesium oxide is hydrolyzed to generate magnesium hydroxide and refined, and then calcined at high temperature to obtain silicon steel grade magnesium oxide. Japan uses the brine lime method to generate magnesium hydroxide, and magnesium hydroxide is then calcined at high temperature to prepare silicon steel grade magnesium oxide. Israel uses a vertical kiln for calcination, while Japan uses a rotary kiln for calcination.
According to the “2021 Global and China Silicon Steel Grade Magnesium Oxide Industry In-depth Research Report”, driven by the continued growth of downstream market demand, in 2020, the market size of China’s silicon steel grade magnesium oxide industry exceeded 400 million yuan, and will grow further in the future. On the one hand, with the development of the silicon steel industry in North China, the demand for silicon steel grade magnesium oxide will continue to increase; on the other hand, the continuous research and development improvements and production technology progress of the silicon steel grade magnesium oxide industry will also promote the continuous development of its industry, thereby increasing the downstream demand for it.
From the perspective of imports, Russia, the United States, Japan and other countries and regions started the industrialization of silicon steel grade magnesium oxide early, and have the world’s top silicon steel grade magnesium oxide production enterprises, which are the main importing countries of silicon steel grade magnesium oxide in my country.
From the perspective of exports, the number of current silicon steel grade magnesium oxide production enterprises in my country is increasing, including Hebei Messi Biology Co., Ltd. and other companies. In the future, as my country’s silicon steel grade magnesium oxide production technology continues to mature, my country’s silicon steel grade magnesium oxide output will further increase. Against the background of the continuous advancement of strategies such as the “Belt and Road” and “Going Global”, my country’s silicon steel grade magnesium oxide products will be exported to more countries and regions.
Hebei Messi Biology Co., Ltd. believes that in the future, with the deepening of urban network transformation and smart grid construction, the market demand for my country’s oriented silicon steel sheet industry will continue to increase, thereby promoting the growth of demand for silicon steel grade magnesium oxide products. In addition, my country’s high-end silicon steel grade magnesium oxide product market production capacity is insufficient and has a certain dependence on imported products. There is still a large space for import substitution in market development.
