Converter Furnace Refractories

Magnesia Carbon Brick for Converter Magnesia carbon brick for convertor is made adopting fused magnesite, high carbon graphite as principal raw material, mixed with antioxidant, use phenolic resin as binding agent, pressed with high pressure. Magnesia carbon bricks for convertor has good erosion resistance and thermal shock resistance, mainly used in convertor. http://www.ruizhirefractory.com/en/product/magnesia-carbon-brick-for-converter.html

Tap Hole Brick Tap hole brick is made by adopting high purity fused magnesite and graphite as principal raw material, use unique antioxidant and resin as binding agent, formed by isostatic compaction. It has good oxidation resistance, high strength, good erosion resistance and integrity, easy to be changed, low service life, is an ideal material for tap hole of large and middle sized converter. http://www.ruizhirefractory.com/en/product/tap-hole-brick.html

refractory materials First, with refractories mainly in the following areas: 1) Refractory for converter The current converter furnace cap, tapping port, before and after the large surface, the pool and the bottom are used magnesia carbon brick ; trunnion and slag line parts using high-strength magnesia carbon brick. Magnesia carbon refractory brick in the content of MgO is generally 70 ~ 75%, graphite content of 16 ~ 20%, bulk density of 2.8 ~ 2.9g / cm3, compressive strength of 25 ~ 30MPa. High-strength magnesia carbon brick, the composition with magnesia carbon brick, but the pressure strength of 30 ~ 42MPa. 2) refractory for electric furnace Electric furnace furnace bottom, furnace slopes and melting pond for the overall blistering of magnesia, or the use of magnesia carbon brick and tar asphalt combined with magnesia bricks ; hot and slag line area, the use of high quality magnesia brick; furnace door on both sides and tapping El For the magnesia brick, chrome magnesia brick;

refractory material The natural minerals of silica are called quartz. Refractory materials , clay and siliceous refractory material contain more silica. Silica is acidic at high temperatures, and siliceous refractories are resistant to acid residue corrosion. The main raw material for the production of clay refractory brick is natural refractory clay, the main mineral is kaolinite (molecular formula Al2O3 · 2SiO2 · 2H2O), clay brick containing SiO2 between 45% and 65%, are weak acid refractory, Have a certain resistance, but easy to be alkaline slag erosion. Low alumina clay refractory suppliers refers to the alumina content of 10% to 30%, SiO2 content of less than 85%, semi-silica refractory brick ≥ 65% SiO2 content of not less than 93%, natural quartzite as the main raw material of refractories known as silica, mainly silicon bricks, special silica bricks, quartz glass and its products. China's literature generally referred to these products as "silicon refra
