Mag chrome brick is what we make at Ruitai Lianxin when you need real survival in harsh slag. In the non-ferrous metallurgy industry, kilns eat a standard basic refractory fire brick very fast if the quality is poor.
If you build or repair a smelting furnace, you need a strong magnesia chromite brick to handle the severe chemical attack from both acidic and basic slags.
1.Why magnesia chrome brick works in smelters
Why use magnesia chrome brick? Because copper, lead, and zinc smelting slags are brutal.
The combination of high-purity dead-burned magnesia and quality chrome ore gives this magnesia refractory brick a high melting point and great thermal shock resistance.
Our factory workers press these blocks under heavy tonnage. A standard magnesia-chrome brick from our production line forms a dense secondary spinel phase when fired at ultra-high temperatures.
This physical structure directly stops the liquid slag from penetrating the brick pores. We just make sure the bulk density is high enough to resist erosion on the factory floor.
2.Refractory brick for non-ferrous smelting
As a direct factory, we supply the exact refractory brick for non-ferrous smelting you need.
Whether it is a flash smelter, an anode furnace, a Peirce-Smith converter, or an Ausmelt furnace, we have the right mix. For the heavy wear zones, a direct-bonded magnesite chrome brick is strictly necessary.
We check the apparent porosity and cold crushing strength right here in the Ruitai Lianxin refractory bricks supplier testing room before we pack them for export. Sometimes, we also suggest our magnesia-alumina spinel bricks or high alumina bricks for less aggressive zones to save you maintenance costs.
If your furnace lining is wearing out too fast from aggressive slag, talk to us. We are the factory-direct refractory manufacturer. We ship solid, high-density mag chrome brick directly from our kilns to your smelter.
Give us your slag composition and operating temperature, and we will match the exact brick grade for your project.
