The market competition risk of the binder industry for light burned magnesium powder can be divided into market, price risk and operation risk. The first demand risk is that demand is the key factor affecting the sales of binders for refractory materials. The size of demand is relative to the supply volume. If supply increases, demand decreases, and magnesia is burned again, the sales will encounter difficulties; The second is price risk, which refers to the binder products for refractory materials

The light burned magnesium powder does not burn at all. It can operate continuously for a long time at 250 ℃, and it can maintain normal operation for 30 minutes at the limit state of 1000 ℃, without causing ignition source. Even in the case of flame barbecue, light burning of magnesium powder, as long as the flame temperature is lower than the melting point temperature of copper, the cable can continue to be used without replacement after the flame is eliminated. The feeling of being barbecued by fire

What is magnesia? Heavy burned magnesia magnesia is calcined from magnesite, bischofite or magnesium hydroxide extracted from seawater at high temperature. 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. Magnesium produced from natural magnesite by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln

1. The content of magnesium oxide is proportional to its activity in a certain range, but there is no such strict or reliable proportional relationship; Light burning magnesium ball 2. It is a serious mistake to think that "it will be inversely proportional if it exceeds this range"! 3. The current magnesium oxide is misunderstood by some people as light burned powder, which is also a serious mistake. It should be said that the main component of light burned powder is magnesium oxide,

Clinker particles in the kiln are formed under the action of liquid phase (some data call melt), and the liquid phase forms capillary bridge outside the crystal. The liquid phase capillary bridge plays two roles in light burning of magnesium powder: one is to bind the particles together, the other is to act as an intermediate medium to make CaO and C2S diffuse in the molten state to generate C3S. The strength of the particles depends on the strength of the capillary bridge

It is mainly used as slag protection composition regulator for slag splashing and furnace protection of 100% converter. Because slag splashing requires proper viscosity and refractoriness of slag, reasonable slag composition of light burned magnesium ball is the key to solid slag splashing. Generally, the slag cannot be directly splashed to protect the furnace. A certain amount of magnesium oxide balls need to be added for adjustment. At the same time, it can replace the use of dolomite to reduce the amount of slag and improve the quality of slag

Magnesia manufacturers introduce that magnesia can be divided into natural magnesia, seawater magnesia or synthetic magnesia. Natural magnesium oxide mainly comes from natural magnesite, which is calcined magnesite. However, due to the quality of raw ore, it is difficult to obtain high-purity and high-quality products. So far, seawater magnesium oxide has become the main source of magnesium oxide used in industrialized countries. The theoretical content of MgO in magnesite is 47
