Customized magnesia carbon bricks are being produced at a rapid pace and can be shipped after the National Day.
Introduction
Magnesia carbon bricks are made of high melting point basic oxide magnesium oxide (melting point 2800℃) and high melting point carbon material that is difficult to be wetted by slag as raw materials, and various non-oxide additives are added. It is a non-burning carbon composite refractory material combined with a carbon binder. Magnesia carbon bricks are mainly used for the lining of converters, AC arc furnaces, DC arc furnaces, and the slag line of ladles.
As a composite refractory material, magnesia carbon brick effectively utilizes the strong slag erosion resistance of magnesia sand and the high thermal conductivity and low expansion of carbon, compensating for the biggest disadvantage of magnesia sand's poor spalling resistance.
Features:
1. Good high temperature resistance
2. Strong slag resistance
3. Good thermal shock resistance
4. Low high temperature creep
Application:
1. Metallurgical industry
In the field of iron and steel metallurgy, magnesia carbon bricks are mainly used for the lining of high-temperature melting furnaces such as ladles, converters, electric furnaces, and refractory lining materials for various slag mouths, pallets, coke nozzles, ladle covers, etc. Magnesium carbon bricks not only ensure the normal high-temperature chemical reaction and continuous production in the furnace, but also greatly extend the service life of the melting furnace and reduce maintenance costs.
2. Chemical industry
In the chemical industry, magnesia carbon bricks are widely used in the lining, gas barrier and lining of various high-temperature reactors, converters, and cracking furnaces. Compared with traditional refractory bricks, magnesia carbon bricks not only have better high temperature resistance, but also have high carbon content and good electrical conductivity, which can effectively prevent arc burn-through.
3. Other industries
In addition to the metallurgical and chemical fields, magnesia carbon bricks are also widely used in high-temperature melting furnaces, electric furnaces, gantries and railway locomotives in the fields of petroleum, metallurgy, and electric power.
