Key words: alumina-magnesia-carbon brick, magnesia-carbon brick, damage mechanism Although carbon-containing refractories have remarkable resistance to molten steel erosion, slag resistance, good thermal shock […]
Masonry characteristics and use precautions of conductive magnesia-carbon bricks for steelmaking electric furnaces
This article describes the masonry characteristics of refractory materials at the bottom of the conductive furnace and the matters needing attention in the normal use of conductive refractory bricks for DC electric furnaces. Key words: steelmaking; conductive magnesia carbon brick; masonry characteristics; precautions Conductive magnesia-carbon refractories for steelmaking electric furnaces were first developed by Radex […]
Application of magnesia carbon brick in iron and steel metallurgy industry
Magnesia carbon bricks are very suitable for the requirements of iron and steel smelting due to their superior high temperature resistance, slag erosion resistance, and good thermal shock stability. Taking advantage of the properties of carbon materials that are difficult to be wetted by slag and molten steel and magnesia, high slag resistance and solvent […]
Reducing the cost of electric furnace steel – Furnace cover continuous feeding equipment
At present, most electric arc steelmaking furnaces adopt the method of removing the furnace cover, feeding the furnace charge in batches from the furnace top, and directly heating the furnace charge with an electric arc. The most common method of electric furnace steelmaking is cold charging, and cold charging can be divided into manual charging […]
What is the difference between magnesia carbon brick and aluminum magnesia carbon brick
What is the difference between magnesia carbon bricks and aluminum magnesia carbon bricks? The difference between magnesia carbon bricks and aluminum magnesia carbon bricks is that the raw materials used are different. Magnesia carbon bricks are resin-bonded bricks made of fused magnesia. Made of sand and graphite. Magnesia-carbon bricks, if necessary, can also add antioxidants, […]
Features of LMM yoyai magnesia carbon brick
There are two kinds of brick-making methods for magnesia-carbon bricks: fired oil-impregnated magnesia-carbon bricks and unburned magnesia-carbon bricks. The former brick-making process is more complicated and is rarely used. Here, only the characteristics of the brick-making process of unburned magnesia-carbon bricks are briefly described. Sludge preparation: The choice of critical particle size is important during […]
What is electric arc furnace steelmaking equipment
AC electric arc furnace steelmaking equipment includes three parts: furnace body, mechanical equipment and electrical equipment. The layout of the electric furnace equipment is shown in the figure. The equipment structure of the electric arc furnace is mainly determined by the steelmaking process, and it is also related to the capacity of the electric furnace, […]

There are two kinds of brick-making methods for magnesia-carbon bricks: fired oil-impregnated magnesia-carbon bricks and unburned magnesia-carbon bricks. The former brick-making process is more complicated and is rarely used. Here, only the characteristics of the brick-making process of unburned magnesia-carbon bricks are briefly described. Preparation of mud. The choice of particle critical size is important […]
What is the use of magnesia carbon brick
The magnesia-carbon brick magnesia-carbon refractory was successfully developed by the United States in the mid-1960s. In the 1970s, the Japanese steel industry began to use magnesia-carbon bricks in water-cooled electric arc furnace steelmaking. At present, magnesia-carbon bricks have been widely used in steelmaking around the world, and have become a traditional use of graphite. In […]
Main properties and uses of magnesia carbon bricks
Magnesia-carbon bricks are made of magnesia, dead-burned magnesia, fused magnesia, high-purity magnesia and high-quality graphite and bauxite additives. The price of magnesia-carbon bricks and its performance have a lot to do with the graphite content in the bricks. As the graphite content increases, the strength of the brick decreases, the thermal expansion rate decreases, and […]
