Magnesia Refractories Bricks for Ladles

Magnesia-based Refractory Bricks for Ladles

According to the construction characteristics of the spray material, combined with the problem that the inner wall of the RH impregnation pipe is washed by high temperature molten steel and the outer wall is corroded by molten slag, the high quality magnesite and magnesia-chrome sand are selected as the main raw materials, and the unique composite binder and admixture are added. This series of products has the characteristics of high adhesion strength, low rebound rate, easy sintering, erosion resistance, erosion resistance, etc. It is the ideal material for spray repair maintenance of RH furnace impregnation pipe and prolonging the service life of RH furnace。

Magnesia Bricks

Magnesia Carbon Brick

PN series magnesia carbon brick is made of high purity, high density fused magnesia or large crystalline fused magnesia, high purity graphite as the main raw material, adding appropriate amount of antioxidants, phenolic resin as the binder, through high pressure forming process。
The product is mainly used in the slag line of ladle, molten pool and the bottom of ladle and other working parts, can significantly improve the service life of ladle, especially when applied to the slag line parts, its service life can be significantly higher than other refractory materials. The product has the advantages of high strength, good slag resistance, good thermal shock stability and high refractoriness. Different grades of magnesia-carbon bricks can be selected according to the smelting conditions and the different grades of steel

Alumina Magnesia Spinel Brick

Magnesia Chrome Brick

PN series magnesia chrome brick is composed of chromium ore and magnesia composite alkaline refractory material, through different combination of pressing molding, high temperature or ultra-high temperature firing, with excellent slag resistance, high temperature strength, erosion resistance and fatigue resistance. Suitable for AOD refining furnace, VOD refining envelope lining, non-ferrous smelting furnace lining and cement kiln lining material.

Alumina Magnesia Carbon Brick

PN series aluminum magnesia carbon brick using super grade bauxite or corundum as aggregate, and focus on strengthening the matrix, phenolic resin as a binder, the use of press molding, with anti-erosion, anti-spalling, high strength characteristics, suitable for steel bag bottom and wall and other parts. PN series magnesia aluminum carbon brick is based on the adjustment of the process and technology of magnesia aluminum carbon brick, enhance the corrosion resistance and anti-stripping of the material, suitable for the bottom of the steel bag and the wall and other parts, can significantly improve the service life of the ladle.

Magnesia-Calcium-Carbon Brick

PN series magnesia-calcium carbon brick is made of special calcium-containing material as raw material and special resin as binder by special waterproofing process. It is mainly used in refining ladle, which can adsorb non-metallic inclusions in molten steel during use and achieve the purpose of purifying molten steel.
The production process of the product solves the problem that the calcium-containing material is easy to hydrate, ensures the quality stability of the product, and improves the slag resistance.
