A kind of magnesia-chromium non-burning brick for AOD furnace and preparation method |
| abstract |
The invention relates to a magnesia-chromium non-burning brick used in an AOD furnace and a preparation method thereof. A magnesia-chromium non-burning brick used in an AOD furnace comprises the following raw materials in parts by weight: 5-10 parts of crystalline magnesia; 15-20 parts of low-ferrous fused magnesia-chromium 20 sand with 0<grain size≤1mm; 25-30 parts of low-ferrous fused magnesia-chromium 20 sand with 1mm<grain size≤3mm; 3mm<grain size≤ 10-15 parts of 5mm low-iron fused magnesia-chromium 20 sand; 10-15 parts of low-iron fused magnesia-chromium 20 sand of 200 mesh fine powder; 8-10 parts of low-iron fused magnesia-chromium 36 sand of 325 mesh fine powder ; 1-3 parts of chromium oxide green; 5-10 parts of Pakistan chrome ore ultrafine powder; 2-4 parts of binder. The advantages are: using low-iron fused magnesia-chrome sand as the main raw material to make unburned chrome-magnesium bricks, the use effect is far superior to the currently used sintered magnesia-chrome bricks and magnesia-calcium bricks. |
