產品詳細介紹

鎂鉻磚Magnesia-Chrome Brick

本系列產品以燒結鎂砂或電熔鎂砂、鉻礦及其精礦、電熔鎂鉻砂等為主要原料,經高壓成型、超高溫燒結制備而成。鎂鉻磚可分為四類:普通硅酸鹽結合鎂鉻磚、直接結合鎂鉻磚、半再結合鎂鉻磚、電熔再結合鎂鉻磚。

This series of products are mainly made of sintered magnesite or fused magnesite, chrome ore and its concentrate, fused magnesia-chrome sand. Magnesia-chrome brick can be divided into four types: ordinary silicate-bonded magnesia-chrome brick, direct-bonded magnesia-chrome brick, semi-bonded magnesia-chrome brick and fused re-bonded magnesia-chrome brick.

普通鎂鉻磚是以MgO含量小于95的燒結鎂砂和SiO2含量高的鉻礦等為原料制備而成,其結合相為低熔相,常用于有色冶煉爐、玻璃窯、RH精煉爐等的襯。

Ordinary magnesia-chrome brick is made of sintered magnesia sand with MgO content less than 95 and chromium ore with high SiO2 content. Its binding phase is low-melting phase and it is often used in permanent lining of non-ferrous smelting furnaces, glass kilns and RH refining furnaces.

直接結合鎂鉻磚是以MgO含量大于95的優質燒結鎂砂、SiO2含量較低的鉻礦等為原料制備而成,其晶界液相少,以(Mg,Fe)(Fe,Al,Cr)2O4復合尖晶石為主,其直接結合程度高,具有強度高、抗熱震穩定性好等優點,常用于RH精煉爐中上部槽工作襯、有色冶煉爐熔池、P-S銅轉爐熔池、VOD爐熔池、玻璃窯及水泥回轉窯燒成帶等。

Direct-boned Magnesia-Chrome brick is made of high quality sintered magnesia with the content of MgO more than 95 and chrome ore with low content of SiO2 , with less liquid phase at grain boundary .It is mainly composed of (Mg,Fe)(Fe,Al,Cr)2O4 composite spinel, with a high degree of direct bonding, high strength and good thermal shock stability. It is often used in the working lining of middle groove and upper groove of RH refining furnace, melting pool of nonferrous smelting furnace, melting pool of P-S copper converter, melting pool of VOD furnace, firing zone of glass kiln and cement rotary kiln.
