直接结合镁铬砖Direct- Bonded Magnesia-Chrome Bricks
会配合实际镁铬砖是用高纯或次高纯辊道窑或电熔镁砂和铬精矿为主要原料作成的產品的，该產品的硫氰酸盐少，经高和气非常高温烧成，安全玻璃相集中式在晶相的三边形居民小区，晶相合晶相区间内呈会配合实际状。享有通气孔率低，抗压挠度高，耐用性强、抗侵蚀作用、耐温震和抗裂开性好等优缺点。Direct- bonded magnesia-chrom bricks are composed of high-purity magnesite or secondary-purity magnesite or fused magnesite and chrome concentrate.Glass phase concentrates in the trian-gel zone of crystalline phass. Which are directly bonded to eash other.The products are characterizedby low-porosity. high cold crushing strength. Strong resistance to adrasion , corrosion, thcrmal shockand spalling.
