The Quantity Demanded for Silicon Steel Grade Magnesium Oxide

Relatively, the development of chemical industry have a lot of trouble this year. Throughout the whole market, a lot of magnesium oxide manufacturers are shut off constantly, especially those who can only produce low-end magnesium oxide, are more serious. Now commonly seen in the market, mostly is high-end products, such silicon steel grade magnesium oxide.

According to foreign reports, TOP 100 enterprises of steel in the world, there are 9 countries 11 steel companies use 98% high pure magnesium oxide to produce silicon steel sheet (plate), which grain is 0.25～0.27)mm×(610～1000)mm. In fact, from 2001, a Japanese company started to use magnesium oxide 99% to produce. There is a huge market of use high pure magnesium oxide to produce silicon steel sheet in the world, and open the foreign market is currently one of the key factors.

With the technology improvement of iron and steel industry, 0.15mm ultra-thin silicon steel sheet will be born in China. According to online data report, the quantity demand in China of high pure magnesium oxide market of nearly 100000 tons, but the output is less, and has a quite large gap. This provides opportunities and favorable conditions for high pure magnesium oxide production and development.

Oriented Silicon Steel Grade Magnesium Oxide Market

Not only have special requirements for the physical parameters, silicon steel grade magnesium oxide but also have special requirements for chemical purity. CaO, B2O3 can reduce refractoriness, so the content is lower, the performance is better. SO4, CL and impurities lower the better. When high pure magnesium oxide is used on silicon steel sheet surface, form a good glass film on its surface, which is called insulation coating. It enhanced silicon insulation, reducing the core loss of silicon steel, while enhancing the magnetic characteristics of oriented silicon steel sheet. So only high grade, high quality magnesium oxide can satisfy the production of oriented silicon steel sheet.

Silicon steel grade magnesium oxide is used as high-temperature annealing separator in the production of oriented silicon steel sheet, which can be used in aviation manufacturing aircraft turbines and mobile phone chips and other high-tech industries. At present, Wuhan Iron & Steel Group used silicon steel grade magnesium oxide 98% of Meishen, solved the raw materials problems of China can’t supply for a long time. In 2001, our magnesium oxide were sent to South Korea’s posco firm international laboratory, analysis and detection, finally got recognized. From then on, our products out of the doors.

The Largest Manufacturer of Silicon Steel Grade Magnesium Oxide

    Silicon steel grade magnesium oxide has excellent permeability(which has great positive magnetic susceptibility) and insulation properties(that is to say conductivity can be as low as 10-14 us/cm dense state). Make the silicon surface to form a good insulating layer and magnetic media, to suppress and overcome the eddy current and skin effect losses in silicon steel core transformer(Referred to as"Iron Loss"). It also can improve the insulation properties of silicon, used as a high-temperature annealing separator. Even more, it also can be used as ceramic materials, electronic materials, chemical raw materials and binder and additive, etc and applied in silicon steel as dephosphorizer, desulfurizer, insulating coating forming agent.

    Production capacity of Hebei Meishen Chemical Technology Co.,LTD is 10,000 tons of silicon steel grade magnesium oxide. Using Japanese technology and Qinghai area fine powder as raw materials, product quality is stable and best. After ultrafine splintered, classifying processing, the product has the characteristics of high content, less hydrochloric acid insoluble matter(including chloride, iron and other impurities), uniform particle distribution, small span, reasonable crystal structure, moderate fineness and viscosity, excellent physical indicators, low hydration. It can effectively solve the production problems of coating uneven, difficult to wash, film formation, uneven, easy to fall off, not easy to film and other undesirable phenomena.

Silicon Steel Grade Magnesium Oxide Wholesale

    Silicon steel grade magnesium oxide is mainly used for manufacturing oriented silicon steel sheet, which the main purpose of is to make the motor iron core and transformer core. In the production, in order to make the iron metal atoms into regular orientation arrangement, and form excellent insulating film on the surface of silicon steel sheet at the same time, we usually add magnesium oxide. On the one hand, it can generate magnesium silicate vitreous insulation coating with silicon, on the other hand it can play the role of removing impurities such as sulfur and phosphorus in silicon steel in the high temperature.

    Silicon steel grade magnesium oxide that Hebei Meishen Chemical Technology Group Co.,LTD produced, has higher chemical purity, good suspension property in water, low hydration rate, and higher activity, can generate magnesium silicate vitreous with silicon easily. The serous fluid of magnesium oxide has a higher requirement for bondability on the surface of silicon steel sheet. We are the most suitable manufacturer of silicon steel grade magnesium oxide for you to choose. We pay a lot of attention to help more manufacturer improve their product quality, looking forward to your factory material purchaser consulting us, and having a pleasant and long-term cooperation.
