Light burnt magnesia powder is an important refractory [ 2021-07-12 ]

Light-fired magnesia powder is a kind of raw material with medium basicity and chemical activity. In addition to being used as refractory and cementitious material, light-fired magnesia powder is also used in other industrial fields. In addition, the development of slag splashing technology for converter protection further expands the application scope of light burning magnesia powder. At present, the slag splashing technology mostly uses light-burned magnesia powder as pellets, such as light-burned magnesia powder pellets, carbon-containing light-burned magnesia pellets and carbon-containing calcium-containing light-burned magnesia powder pellets.

Magnesium oxide and light burnt powder have their respective roles [ 2021-07-12 ]

"Light burning powder" is a product of natural magnesite or brucite lightly burned at about 900 C. It is commonly known as light burning powder. Magnesium oxide is the main chemical composition of light burning powder. Magnesium oxide in general sense refers to magnesium oxide produced by chemical method. Magnesium carbonate or magnesium hydroxide is produced by chemical method using magnesium-containing raw materials, and magnesium oxide is obtained by calcination. Therefore, the so-called magnesia, in general, is the purity, particle size, and other indicators and light-burned powder have significant differences.

Introduction of Light Burning Powder [ 2021-07-12 ]

As magnesite is generally reduced by about 50%, the content of MgO in ores can be almost doubled by light burning. In this sense, light burning of magnesia is the most effective means of MgO enrichment. In addition, light burning is also a preparatory operation for thermal separation and some gravity separation of magnesite. Light burning of magnesia has high activity and is an ideal raw material for producing high bulk density magnesia.

Current Situation and Development Trend of Refractories Industry [ 2021-07-12 ]

Refractories generally refer to inorganic non-metallic materials with refractory degree above 1580 C, including natural ores (refractory raw materials) and various products (refractory products) processed according to a certain process flow according to certain purposes and requirements, which have certain high temperature mechanical properties and good volume stability. Refractories are important basic materials related to high temperature industry, such as iron and steel, non-ferrous metals, petrochemical, building materials, machinery, electricity, environmental protection and national defense.

Introduction of Magnesium Oxide [ 2021-07-12 ]

Magnesium oxide (chemical formula: MgO) is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Light-burned magnesia and magnesia exist in nature in the form of periclase, which is the raw material for magnesium smelting.

Light Burning Powder to Fuel Overall Revitalization [ 2021-07-12 ]

Resources and Exploitation of Magnesium Raw Materials Magnesium raw materials refer to magnesium-containing minerals which can be used to produce magnesia refractories, magnesia chemical materials, metal magnesium and other products. They are mainly divided into solid minerals such as magnesite, dolomite, brucite and liquid minerals such as sea water and Salt Lake brine. Magnesite is one of the most important refractory materials in the world. It is mainly used for calcining light-burned magnesia (CCM), sintered magnesia (DBM), fused magnesia (FM) and other refractory materials. It is the basic material for producing magnesia refractories.

How to detect the activity of magnesium oxide? [ 2021-07-12 ]

Magnesium oxide is widely used in daily life. Light burning powder plays a vital role in the production of some raw materials in industry. It is necessary to test the activity of magnesium oxide when purchasing magnesium oxide. For raw materials, if the activity of magnesium oxide is not enough, it will easily lead to the quality of materials not up to the standard, so its activity is very high. Important, then how to test it? Xiaobian will give you an introduction. Taking magnesium oxide for adhesive as an example, I would like to explain it to you. I hope it will be helpful to you.

Production Advantages of Light Magnesium Oxide [ 2021-07-12 ]

Light burnt magnesium oxide contains three kinds of substances: underburned, overburned and activated magnesium oxide. 1: The so-called underfired products are part of magnesium carbonate which does not form magnesium oxide. (Controlling the setting speed of magnesite products mainly depends on the amount of underfired products;) If there are more underfired products, the burning vector will be higher, and the setting speed of magnesite products made is very fast, which will cause the bursting and deformation of magnesite products.

(Summary description)The function of light burning powder: magnesite calcined at 750-1100 temperature is called "light burning", and its product is called light burning magnesia powder light burning magnesia. Because magnesite burns down about 50%, the content of MgO in the ore can be almost doubled by light burning. In addition, light burning is also a preparatory operation for magnesite thermal separation and some heavy separation. Light burning magnesia has high activity and is an ideal raw material for producing high-volume and dense magnesia.

Information

The function of light burning powder: magnesite calcined at 750-1100 temperature is called "light burning", and its product is called light burning magnesia powder light burning magnesia. Because magnesite burns down about 50%, the content of MgO in the ore can be almost doubled by light burning. In addition, light burning is also a preparatory operation for magnesite thermal separation and some heavy separation. Light burning magnesia has high activity and is an ideal raw material for producing high-volume and dense magnesia.

Light burnt magnesia mainly produces cementitious materials, such as magnesia cement, insulation and sound insulation building materials, as well as ceramic raw materials. After chemical treatment, light burnt magnesia can be made into a variety of magnesium salts, which can be used as raw materials for medicine, rubber, man-made fibers, papermaking and so on. Heavy burnt magnesia. Most of the refractories used for metallurgy are used to make magnesia bricks and Chrome-Magnesia bricks. Magnesia, metallurgical powder and fused magnesium oxide are mainly used for smelting special alloy steel, lining of medium and high frequency induction furnace for nonferrous and precious metals, magnesium crucible and high temperature electrical insulation material.
