Which is the best manufacturer of Baicheng fused magnesia
Thermal conductivity λ= 123.5W/(m · K) (at 100 ℃), decreases with temperature rise. The elastic modulus is 1.96 MPa. The chemical property is stable, and there is no reaction or weak reaction between it and various refractory materials except silica brick at a high temperature of 1500 ℃. The grain size of periclase increases with the increase of calcination temperature and holding time, and the slag resistance is also improved. See the table for the quality requirements of fused magnesia in China.

Common fused magnesia is a general term for the products of magnesite and other magnesite raw materials that have been treated at high temperature to reach the degree of sintering. Magnesite fired from natural magnesite by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln is called sintered magnesite; The fused magnesite is formed by melting magnesite in electric arc furnace and cooling

Some enterprises and individuals in China still have a weak awareness of energy conservation. All levels should further strengthen the promotion of energy conservation concepts, so that the concept of energy conservation can be truly rooted in the hearts of the people. In this way, the consumption demand for energy-saving refractory products will increase significantly, which will be conducive to the expansion of the production scale of energy-saving refractory products and the development, improvement and promotion of energy-saving technologies.

According to the analysis, from the perspective of supply and demand, the current factory stock is generally tight. In addition, the arrival of the summer solstice on June 21 means that the "mode" is open throughout the year, workers work hard, and the factory output is limited. It is expected that the magnesium factory quotation will remain firm and upward, and the magnesium price will be difficult to decline. Considering that it is difficult for downstream users to accept the high price, and that downstream enterprises will also carry out equipment maintenance in summer, it is not easy for magnesium prices to rise due to weak demand, so magnesium market will be more stable this week.

What are the main contents of magnesia? The medium grade magnesia mainly contains 94% and 95%. The medium grade magnesia is produced from light burned magnesia with 97% MgO as raw material through ball pressing, high-temperature shaft kiln calcination and other processes. The product has good sintering degree and dense crystallization. It is a high-quality raw material for producing medium grade magnesia refractory products.
