Henan magnesite refractory product manufacturer competitive price magnesia carbon bricks for ladle and EAF electric arc furnaces

Magnesia carbon bricks for steel converter and bof steelmaking are made of high-melting alkaline oxide magnesium oxide (melting point 2800℃) and high-melting carbon materials that are difficult to be infiltrated by slag as raw materials, with various non-oxide additives added. A non-burning carbon composite refractory material combined with a carbon binder. Magnesia carbon bricks are mainly used for lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladle.

As a composite refractory material, magnesia carbon bricks effectively utilize the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, which compensates for the biggest disadvantage of poor spalling resistance of magnesia.

Magnesia carbon bricks are made of dead burnt magnesia (or fused magnesia) and carbon materials (mainly crystallized graphite) as raw materials, using resin as a binder to prepare and press, and heat treatment. In order to improve the oxidation resistance, antioxidants such as metals are often added.

Magnesia carbon bricks is an ideal lining material with good thermal shock stability, corrosion resistance and spalling resistance.

The main characteristics of magnesia carbon bricks are:

Good high temperature resistance;
Strong slag resistance;
Good thermal shock resistance;
Low high temperature creep.

Technical data of Magnesia carbon brick:

Magnesia carbon bricks usage:

Magnesia carbon bricks have a wide range of uses, and can be used in key parts of thermal equipment such as steel-making converters, electric arc furnaces, ladles, and out-of-furnace refining furnaces.

Since the use of magnesia carbon bricks instead of magnesia chrome bricks in my country's refined ladle slag line bricks, the comprehensive use effect is obvious. The 300t ladle slag line of Baosteel Co., Ltd. started to use MT-14A magnesia carbon bricks in July 1989, and the life of the slag line was maintained above 100 times; the 150T electric furnace ladle slag line used low-carbon magnesia carbon bricks to smelt cord steel, and the tapping temperature 1600℃~1670℃, the obvious effect has been achieved.
