Light burned magnesia is an alkaline refractory raw material. The raw material for producing magnesia is magnesium carbonate, commonly known as magnesite. Magnesia can be roughly divided into heavy burned magnesia, medium grade magnesia, high-purity magnesia, fused magnesia, large crystal fused magnesia. The main component of these magnesia is Mgo magnesia. Our factory recommends that the refractory coating should choose over 90% of heavy burned magnesia or 95% of heavy burned magnesia

Light burned magnesium powder is the product of light burning of natural magnesite or brucite at about 900 ℃. It is commonly known as light calcined powder. The main chemical composition of calcined powder is magnesium oxide. Generally speaking, magnesium oxide refers to magnesium oxide produced by chemical method. It is the magnesium oxide obtained by calcining the magnesium carbonate or magnesium hydroxide produced by chemical method using magnesium containing raw materials& n

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

The market competition risks in the bond industry for light burned magnesium pellets can be subdivided into market, price risk and operation risk. First, demand risk. 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, sales will encounter difficulties; The second is price risk. If the price of binder products for refractory materials is high

Introduction of light burned magnesia powder in China. In recent years, the situation of light burned magnesia powder steel industry is severe, the cost pressure before iron production increases sharply, and the quality of iron ore powder continues to deteriorate. In order to stabilize the sinter quality and further reduce the ironmaking production cost, Jingtang Company of Shougang has finally realized natural magnesium sintering through a series of basic research, with sinter grade, strength, particle size, metallurgical performance and droplet performance

Light burned magnesia powder also contains three substances (as the saying goes): under fired products, over fired products and active magnesium oxide 1: The so-called under fired products are some magnesium carbonate that does not form magnesium oxide. (The control of the setting speed of magnesite products mainly depends on the number of under fired products.) If there are more under fired products, the burning vector will be high, and the setting speed of the produced magnesite products will be particularly fast, which will lead to the bursting of magnesite products,

The service life of light burned magnesium spheres is a comprehensive technical index for converter steelmaking. Increasing the furnace life can not only reduce the consumption of refractory materials, but also help to balance the organization of production and promote the virtuous cycle of production. Therefore, it is always the goal of iron and steel enterprises to greatly increase the converter life. The converter lining works under the condition of high temperature and high oxidation, usually at the speed of 0.2-0.8mm/furnace

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

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

Light burning magnesium ball rotary kiln incinerator, also known as rotary kiln, is a slightly inclined steel hollow cylinder lined with firebricks. Most waste materials are heated by the gas generated in the combustion process and the heat transferred by the kiln wall. Solid waste is sent into the kiln from the front end for incineration, and the purpose of mixing waste is achieved by rotating. Proper inclination shall be maintained during rotation to facilitate the sliding of solids
