Product Description

TR Series magnesia fire brick is using high grade magnesia clinker as raw material , the paper pulp as a binder. After mixing and high-pressure forming, in high-temperature tunnel kiln firing which over ***0 ℃. Periclase to the main phase of the basic fire-resistant products. The quality of our products fully exceed the national standards GB/T********1. Product features: Stability of the size and residue of anti-erosion Excellent performance of basic slag resistance, high refractoriness, thermal stability, anti-erosion and anti-peeling Excellent strength of pressure bending, abrasion proof Excellent performance of high-temperature firing, high rates of associative property , anti-erosion ability Excellent thermal shock resistance and spalling resistance Excellent ability of high refractoriness, anti-erosion of alkaline residue; High temperature load of refractoriness under load. Product application: Wall and bottom of steel furnace basic open-hearth furnace, electric furnace, iron alloy furnace wall and bottom Permanent lining of oxygen converter High temperature industrial furnace of mixer, non-ferrous metal smelt industry, Building materials of cement, annealing magnesia the lining of the kiln, glass furnace brick of lattice top, high-temperature tunnel kiln etc Wall and furnace wall of hot rolling mill and soaking pit furnace Item Index MZ**7A MZ**7B MZ**5A MZ**5B MZ**3 MZ**1 MZ**9 MZ**7 MgO/% ≥ *7 *6.5 *5 *4.5 *3 *1 *9 *7 SIO2/（%） ≤ 1.0 2.0 2.0 2.0 3.5 － － － CaO （%） ≤ － － 2.0 2.0 2.0 3.0 3.0 3.0 Apparent porosity /（％）≤ *6 *8 *6 *8 *8 *8 *0 *0 Cold crushing strength/（MPa）≥ *0 *0 *0 *0 *0 *0
