2020-01-02 16:06:15

Since its establishment, our factory has been committed to the deep processing industrialization of magnesite by relying on the abundant magnesite resources in Dashiqiao City the advantages of convenient transportation smooth access. Our factory mainly produces refractory materials such as light burnt magnesium powder, light burnt magnesium ball, heavy burnt magnesia, bitter earth powder, fused magnesium, metallurgical sand, etc. The products are mainly used in metallurgy, chemical industry, feed, environmental protection, medicine, fertilizer Building materials other industries. At the same time, it also runs various kinds of powder Raymond processing, can adjust various physical chemical indicators according to customer needs. Light burned magnesium powder

Our factory has strong production capacity, strong technical force, perfect detection methods, skilled worker operation skills, products have passed ISO9000 international quality system certification. At present, the products have been exported to more than 20 countries regions including Europe, America, North South America, Southeast Asia, are well received by customers.

Based on the business tenet of "business with virtue, reputation first", our factory is willing to cooperate better with domestic foreign users, meet the needs of our customers with high-quality products the best price, warmly welcome to negotiate Cooperation.


Light burnt magnesium powder, referred to as light burnt magnesium powder, is an active magnesium oxide obtained by calcining magnesium hydroxide extracted magnesite, brucite seawater brine at about 800 ~ 1000 ℃. Light burnt magnesium powder is light yellow light brown powder, the particle size is mostly below 100 mesh, the perovskite crystal is very small, the density is 3.07 ~ 3.22g / cm3, the lattice constant is large, the lattice defects are many, the texture is crisp Porous structure, great reactivity, easy to carry out solid phase reaction sintering, generate Mg (OH) 2 with water harden, with bonding ability.

Selecting the calcination method controlling the light burning temperature are important means to obtain good activity. As the calcination temperature increases, the specific surface area of MgO decreases significantly. When the temperature is greater than 1000 ° C, the recrystallization speed of MgO increases, the degree of dispersion drops sharply, the activity becomes poor. Using different calcination methods calcination equipment at the same temperature is also an important factor affecting the activity of MgO. If it is calcined by a boiling furnace a suspension furnace, it can be quickly decomposed in an instant, active light-burned magnesium oxide powder can be obtained. The use of large kilns in tunnel kilns reflection kilns, long calcination time, will often cause over-burning of the surface internal burning, which will reduce the activity of lightly burned magnesium oxide powder. The rotary kiln is used to calcine the granular magnesite, the situation is somewhere in between, which can also keep the lightly burned magnesia powder maintain good activity.

Light burned magnesium powder is a kind of raw material with medium alkalinity chemical activity. It is also used in other industrial fields besides being used as refractory gelling material. In addition, the development of converter slag splashing furnace protection technology has further expanded the application range of lightly burned magnesium oxide powder. At present, the slag splashing furnace protection technology mostly uses lightly burned magnesium oxide powder into balls. There are lightly burned magnesium oxide powder balls, carbon-containing lightly burned magnesium oxide sub-balls carbon-containing calcium-containing lightly burned magnesium balls.
