[ Company News ] Reburned magnesia is an important refractory

Refractory magnesia is a kind of raw material with medium alkalinity and chemical activity, which is not only used as refractory and cementitious material, but also used in other industrial fields. In addition, the development of converter slag splashing technology has further expanded the application range of light burned magnesia powder. At present, slag splashing furnace protection technology mostly uses light burned magnesia powder to form balls, including light burned magnesia powder balls and carbon containing light burned magnesia

[ Company News ] The difference between calcined magnesia and large crystal fused magnesia

The calcined magnesite is mainly composed of 46% magnesite ore, which is calcined at 1600 ℃ - 1800 ℃ through a layer of coal and a layer of magnesite in the iron sheet kiln. The production process is that two tons of ore can produce one ton of heavy burned magnesia, which can be divided into three grades; 1、 Reburning magnesia in front of kiln, II. Underburning reburning magnesia, III, large pieces of reburning magnesia, the main color of reburning magnesia products is hard

[ Industry News ] Guide to use of calcined magnesia

What is the relationship between the operating temperature of the calcined magnesia component and the insulation resistance? For almost all insulating materials, the higher the temperature is, the smaller the insulation resistance value will be. The insulation performance of magnesium oxide powder conforms to this rule. What effect does the minimum insulation resistance value have on the overall design? During product design, we should make clear the minimum value of insulation resistance of components at the highest operating temperature, and whether it can meet

[ Industry News ] Is your calcined magnesia deteriorated and expired

Strictly speaking, magnesia beyond its shelf life will generally affect the activity of the calcined magnesia itself. However, if the stock is large, discard it and worry about waste. Now we tell you that you can check whether it can be used again from the following aspects. The production of desulfurized magnesium oxide shall be initially inspected. Normally, magnesium oxide should be white powder. If oxidized

[ Industry News ] What are the products of refractories reburning magnesia?

Reburned magnesia is very advantageous in producing refractory products because of its fire-resistant properties. It is mainly used in steel industry, glass, cement, nonferrous metallurgy, etc., and is also an ideal high-quality material for manufacturing unshaped refractory bricks. From the perspective of historical development, sintered magnesia is also called metallurgical magnesia, calcined magnesia, medium grade magnesia and high-purity magnesia. Magnesite

[ technical knowledge ] Reburned magnesia has great influence on rubber density

The influence of calcined magnesia on the density of rubber compound is great. The strength and elongation properties and thermal aging have no change after use. The reduction of magnesium reduction by 30% - 70% is much better than that of ordinary magnesium carbonate; The wear reduction loss of magnesium oxide is better than that of ordinary magnesium oxide, which is not reduced. The cost is reduced after the density and magnesium density are reduced, and the weight of desulfurized magnesium oxide is reduced

[ technical knowledge ] Effect of properties of magnesia refractories on refractories

Magnesite is calcined at high temperature from magnesite, bischofite or magnesium hydroxide extracted from seawater. 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. The magnesia produced by the magnesia manufacturer with natural magnesite as raw material is called sintered magnesia by using the one-step or two-step calcination process of high-temperature equipment such as shaft kiln and rotary kiln; With magnesite, etc
