China is always a producing nation of magnesium oxide, but the products are mainly focus on low-end magnesium oxide products. With the increase of Chinese electrical steel capacity, the quantity demanded of silicon-steel grade magnesium oxide is just how much every year.
Silicon-steel grade magnesium oxide is the magnesium oxide suitable for making oriented silicon steel sheets. Silicon-steel grade magnesium oxide is a kind of coating material. It is used in high temperature annealing processing phase of oriented silicon steel, and plays the role of separant, insulating film layer, desulfurization, dephosphorization, etc. In 2008, the demand of domestic enterprises for silicon-steel grade magnesium oxide is 100 thousands tons, however, the domestic production is one thousand tons. It can not meet the requirement of domestic enterprises. Therefore, the market of silicon-steel grade magnesium oxide has a great potential. It is necessary to strengthen the research and product for silicon-steel grade magnesium oxide.
The silicon-steel grade magnesium oxide researches and develops independent by Hebei Meishen Technology Limited Company is adopts the Japanese technology and Qinghai pollution-free area’ raw materials. The quality of product has a good stability. The silicon-steel grade magnesium oxide product has high content through ultrafine grinding and stage treatment. The impurity is less, such as insoluble matter in hydrochloric acid, chloride, iron and so on. The particle distributions, the span is small. he silicon-steel grade magnesium oxide from Hebei Meishe Technology Limited Company can effective solve unhealthy phenomenon like nonuniform coating, not easy irrigation, not easy to form coating and so on. It also can solve the problems such as the useless produced high temperature laminate, bad insulation performance, low qualified, etc.
