magnesia carbon brick

magnesia carbon brick

Magnesia carbon brick is a kind of important refractory material used in steelmaking converter, steel making electric furnace, steel refining furnace and its ladle as lining (lining). As the erosion resistance, not easy to slag, so the use of magnesia brick can significantly improve the life of steel-making furnace (bag).

Magnesia carbon bricks is the use of high-quality fused magnesia, high purity flake graphite, metal additives and other raw materials, phenolic resin as a binder by high-pressure molding, about 200 ℃ heat treatment made of a refractory material. High quality magnesia carbon bricks to ensure the service life and safety, the use of poor quality magnesia carbon brick masonry furnace easy to burn, the occurrence of running steel, leakage of steel, casualties and other vicious accidents, so the procurement must be good Quality off.

Magnesia carbon refractory brick the classification of magnesia carbon bricks and provides the corresponding technical performance indicators, the user can be used as a procurement conditions.

The appearance of the black and white carbon bricks, the appearance of oil black shiny, cross-section neat; poor magnesia carbon refractory brick appearance rough white point, cross-section has a layer, resulting in particle segregation, and particles continue.

Magnesia carbon bricks physical and chemical indicators with the naked eye is difficult to judge, the user can randomly send the authority to send the department for quality inspection. Magnesia carbon brick requirements of the physical and chemical indicators are as follows: MgO content, C content, significantly porosity, bulk density, room temperature compressive strength, high temperature bending strength.

Magnesia carbon bricks is easy to hydrate, so the magnesia carbon brick must be kept in the rain, moisture-proof warehouse. Packaging and transportation should also take measures to prevent rain and moisture, the magnesia carbon bricks once the damp, product quality will decline, serious will lead to magnesia carbon brick products scrapped.

Alumina magnesia carbon brick With the development of new technologies such as refining and continuous casting, the temperature of molten steel and the residence time of molten steel in ladle can be prolonged, and the refractory material of steel ladle refractory lining is more serious. So the alumina magnesia carbon brick is developed and achieved the expected effect. Al2o3-mgo-c brick is characterized with simple construction, moderate cost, convenient unpacking and good use effect. According to the production need, ladle bricks must have good comprehensive performance.In the high alumina matrix, adding MgO powder, aluminum magnesium spinel can be formed at high temperature, improve the performance of the refractory brick . In order to improve alumina magnesia brick slag resistance, thermal shock resistance, adding the right amount of carbon materials. In order to improve the oxidation resistance of the refractory brick, adding the amount of antioxidant. Alumina magnesia carbo

ladle slide gate plates 1 Preparation of refractory mud: Phosphate mud and graphite powder in accordance with the ratio of 2: 1 poured in the mud bucket, the powder particles or debris in the group have to pick the net uniform mixing plus 20% diluted with water , Mix evenly, and covered with plastic paper to prevent dust, debris, etc. into the refractory mud. 2 Check the fire-resistant clay, skateboard brick, brick nozzle quality and site reserves, when the mud appears wet caking, skateboards and bricks do not meet the acceptance criteria prohibit the use of. 3 Check to confirm the work of two hot fix hydraulic station, working pressure should meet 12 ~ 15Mpa, cantilever crane rotation, lifting and other working conditions are normal, there are problems in time to contact the maintenance staff to deal with. 4 Check All kinds of energy medium pipeline, fittings, valves, hoses no leakage point, there is a leak must contact the handle before use. 5 All kinds of tools used in productio

Green mortar mass Green mortar mass Introduction: Green mortar mass has good adhesion and high refractoriness, which is an ideal product to fill gaps in between slide gate plate and nozzle. The green mortar mass is to process the green mortar to the finished product as a mass, which is convenient for transportation and more convenient for customers to use. Advantage: The Green mortar mass is convenient for customers to transport and use. Green mortar mass has strong fluidity, no sintering, and no steel leakage. Green mortar mass is also commonly used in the tundish quick-change nozzle. The green mortar mass is used between the slide gate plate and the mechanism to prevent the slide gate plate from loosening steel and sticking to the machinery during use.
