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 …

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 …

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 …

Introduction to the characteristics of magnesia carbon bricks

The melting point of high temperature resistant graphite is 3850℃±50℃, and the boiling point is 4250℃. Even if it is burned by ultra-high arc, the loss of quality is very small, and the coefficient of linear expansion is also very small. The strength of graphite increases with the increase of temperature. At 2000 ℃, the …
