Modified compact refractory brick for plasma melting furnace and preparation method
The invention discloses a modified compact refractory brick for a plasma melting furnace and a preparation method. The modified compact refractory brick comprises the following raw materials in parts by weight: 30-35 parts of granules, 12-15 parts of borax, 12-16 parts of calcined alumina, 10-15 parts of corundum powder, 10-15 parts of ball clay, 9-14 parts of calamine, 3-5 parts of a modifier, 8-10 parts of chromium dioxide and 1.0-1.5 parts of iron oxide. Comprising the following steps: S1, fine powder processing, S2, slurry preparation, S3, mixing and grinding processing, S4, ageing and molding, and S5, firing, and the modified compact refractory brick obtained by the raw materials and the preparation method has the advantages of large density, small apparent porosity, good thermal insulation effect and good strength performance.
本发明公开了一种等离子熔融炉用改性致密耐火砖及制备方法，改性致密耐火砖原料按重量份数计包括：颗粒料30～35份，硼砂12～15份，熟矾土12～16份，刚玉粉10～15份，球粘土10～15份，炉甘石9～14份，改性剂3～5份，二氧化铬8～10份，氧化铁1.0～1.5份；包括如下步骤：S1、细粉加工，S2、泥浆制备，S3、混碾加工，S4、困料成型，S5、烧成，通过上述原料及制备方法得到的改性致密耐火砖的密度较大，显气孔率较小，同时具有良好的隔热效果以及强度性能。
