Periclase and Graphite Refractory Brick MT14A for Steel Ladle Slag Line in Henan Xinmi

Henan Xinmi Industrial furnace refractories magnesia carbon brick for steel ladle slag line MT14A

Magnesia carbon bricks for steel ladle 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 form a carbon skeleton bond when used at high temperatures. Since magnesium oxide and carbon do not have a mutual soluble relationship, the excellent fire resistance of the original components is retained. Carbon has good thermal conductivity, low thermal expansion coefficient and low elasticity coefficient, which can effectively prevent high-temperature spalling and slag penetration, and is not prone to structural spalling, which greatly changes the fatal weakness of degraded structure spalling caused by magnesia refractory slag penetration.
 
Coupled with the non-wetting of carbon to slag, the corrosion resistance is also good. These series of characteristics of magnesia carbon bricks make it 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.

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.
