产品详细介绍

镁铬砖Magnesia-Chrome Brick

本系列产品以烧结镁砂或电熔镁砂、铬矿及其精矿、电熔镁铬砂等为主要原料,经高压成型、超高温烧结制备而成。镁铬砖可分为四类:普通硅酸盐结合镁铬砖、直接结合镁铬砖、半再结合镁铬砖、电熔再结合镁铬砖。

This series of   products are mainly made of sinteredmagnesite or fused magnesite, chrome ore   and itsconcentrate, fused magnesia-chrome sand. Magnesia-chrome brick canbe   divided into four types: ordinary silicate-bondedmagnesia-chrome brick,   direct-bonded magnesia-chrome brick,semi-bonded magnesia-chrome brick and   fused re-bondedmagnesia-chrome brick.

 

普通镁铬砖是以MgO含量小于95的烧结镁砂和SiO2含量高的铬矿等为原料制备而成,其结合相为低熔相,常用于有色冶炼炉、玻璃窑、RH精炼炉等的衬。

Ordinary magnesia-chrome brick is made of sintered magnesia sandwith MgO content less than 95 and chromium ore with high SiO2content. Its binding phase is low-melting phase and it is oftenused in permanent lining of non-ferrous smelting furnaces, glasskilns and RH refining furnaces.

直接结合镁铬砖是以MgO含量大于95的优质烧结镁砂、SiO2含量较低的铬矿等为原料制备而成,其晶界液相少,以(Mg,Fe)(Fe,Al,Cr)2O4复合尖晶石为主,其直接结合程度高,具有强度高、抗热震稳定性好等优点,常用于RH精炼炉中上部槽工作衬、有色冶炼炉熔池、P-S铜转炉熔池、VOD炉熔池、玻璃窑及水泥回转窑烧成带等。

Direct-boned Magnesia-Chrome brick is made of high magnesia with the content of MgO more than 95 and chromeore with low content of SiO2 , with less liquid phase at grainboundary .It is mainly composed of (Mg,Fe)(Fe,Al,Cr)2O4 compositespinel, with a high degree of direct bonding, high strength andgood thermal shock stability. It is often used in the workinglining of middle groove  and upper groove of RH refiningfurnace, melting pool of nonferrous smelting furnace, melting poolof P-S copper converter, melting pool of VOD furnace, firing zoneof glass kiln and cement rotary kiln.
