Ladle Refractories

Magnesia chrome brick is made of some preliminary synthesis high purity raw materials. The high purity raw refractories should be high pressure formed, ultra high temperature fired and then go through some other post-treatment process and system, finally made the magnesite chrome brick. Magnesia chrome brick has high room temperature compressive strength, low porosity, strong erosion resistance and scouring resistance, etc. Usually it is used for bottom part of VOD.

The company uses high-grade magnesia and strict process to produce magnesium oxide content of more than 90%, with periclase crystalline phase mainly basic refractories. Magnesia brick has high refractoriness, good alkali resistance slag resistance, high load softening starting temperature, but poor thermal shock resistance. Sintered magnesia bricks to magnesia brick as raw material, crushing, ingredients, kneading, after molding at a high temperature 1550 ~ 1600 ℃ firing, high-purity products in firing temperature above 1750 ℃. Unfired magnesite bricks is added to the appropriate chemical binding agent in the magnesia by mixing, forming, drying made. Mainly used for steelmaking basic open hearth furnace bottom and the furnace wall, the permanent lining oxygen furnace, non-ferrous metal smelting furnace, high-temperature tunnel kiln, calcined magnesia brick and cement rotary kiln lining, furnace and hearth furnace wall, glass furnace regenerator checker bricks and so on.

Tundish nozzle well block can be used with all kinds of tundish nozzles. Source: http://www.ruizhirefractory.com/en/product/tundish-nozzle-well-block.html Email: sales@ruizhirefractory.com

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
