Analysis of Factors Affecting Bar Continuous Rolling Round Bar Size

Round steel production is more difficult than thread production; it is mainly reflected in the product quality control of round steel. In the early stage of production, the head and tail of the product were too long, which seriously affected the yield of round steel. After long-term exploration, some factors affecting the dimensional accuracy of […]

Analysis on the Quality of Hot Rolled Coils

The main process equipment of 1580 hot-rolled strip production line are: two three-stage regenerative walking furnaces, post-furnace dephosphorization, one four-high reversible roughing mill, coil box, fine phosphorus removal, and seven four-high finishing mills , Layer cooling roller table, three downcoilers with three auxiliary rollers, walking beam transport area. As the market competition becomes more and […]

How to deal with the problem of reducing the carbon content of magnesia carbon bricks

With the progress of smelting technology and new requirements for refractory materials, traditional magnesia-carbon bricks have found the following problems in the long-term application and practice process: ①Due to the increase of heat loss due to the high thermal conductivity, the tapping temperature is increased, resulting in an increase in energy consumption, and at the […]

Application of magnesia carbon brick

The refractory material used in the early ladle slag line was directly combined magnesia-chrome bricks, Electrofusion combined with high-quality alkaline bricks such as magnesia-chrome bricks. After the MgO-C brick was successfully used in the converter, the MgO-C brick was also used in the refining ladle slag line, and good results were obtained. China and Japan […]

Process of magnesia carbon refractory brick

Raw material The main raw materials of MgO-C bricks include fused magnesia or sintered magnesia, flake graphite, organic binders and antioxidants. Magnesia Magnesia is the main raw material for the production of MgO-C bricks. There are fused magnesia and sintered magnesia. Compared with sintered magnesia, fused magnesia has the advantages of coarse periclase crystal grains […]

The preparation process of magnesia carbon brick

Traditional magnesia-carbon bricks made with synthetic tar binders according to the cold mixing process harden and acquire the necessary strength during tar damage, thus forming isotropic glassy carbon. This carbon exhibits no thermoplasticity, which in time relieves substantial stress during liner baking or handling. The magnesia-carbon brick produced with pitch binder has high high temperature […]

The role of magnesia carbon brick

Magnesia-carbon bricks are made of high melting point alkaline oxide magnesia (melting point 2800C) and high melting point carbon materials that are difficult to be infiltrated by slag as raw materials, and various non-oxide additives are added. Non-burning carbon composite refractory material combined with carbon binder. Magnesia-carbon bricks are mainly used for the lining of […]

Types of Magnesia Carbon Bricks

[vc_row][vc_column][vc_column_text] Magnesia Carbon Bricks Magnesia Carbon Brick is a resin-bonded brick produced from dead-burned or fused magnesia and graphite. Anti-oxidant is also added if needed. Magnesia-Carbon brick works well in thermal resistance, corrosion, resistance, and spalling resistance. Where it is used ? Magnesia Carbon Brick is used in converters, EAFs ( Electric Arc Furnaces ), […]
