Titanium-rich corundum composite silicon carbide unburned brick and preparation method thereof
The invention provides a titanium-rich corundum composite silicon carbide unburned brick and a preparation method thereof. The titanium-rich corundum composite silicon carbide unburned brick is prepared from the following raw materials in percentage by mass: 0 to 10 percent of brown fused alumina of 5 to 3mm, 0 to 40 percent of brown fused alumina of 3 to 1mm, 0 to 25 percent of brown fused alumina of 1 to 0mm, 0 to 10 percent of titanium reinforced corundum of 5 to 3mm, 0 to 35 percent of titanium reinforced corundum of 3 to 1mm, 0 to 25 percent of titanium reinforced corundum of 1 to 0mm, 15 to 25 percent of titanium reinforced corundum of 200 to 325 meshes, 10 to 20 percent of silicon carbide of 200 to 325 meshes, 1 to 3 percent of silica fume and 5 to 8 percent of binding clay. And a binding agent accounting for 3-5% of the total weight of the raw materials is additionally added. The raw materials are subjected to compression molding and low-temperature treatment cooling to obtain the product. The method adopts low-temperature treatment, does not need high-temperature sintering, has the characteristics of slag, alkali and molten iron erosion resistance and excellent permeation resistance, shortens the production cycle and reduces the cost.
本发明提供一种富钛刚玉复合碳化硅不烧砖及其制备方法，所述富钛刚玉复合碳化硅不烧砖由以下质量百分比原料制成：5～3mm的棕刚玉0～10%、3～1mm的棕刚玉0～40%、1～0mm的棕刚玉0～25%、5～3mm的钛增强刚玉0～10%、3～1mm的钛增强刚玉0～35%、1～0mm的钛增强刚玉0～25%、200～325目的钛增强刚玉15～25%、200～325目的碳化硅10～20%、硅灰1～3%和结合粘土5～8%组成；外加占上述各种原料总重量3～5%的结合剂。各原料压制成型，低温处理冷却得到产品。本发明采用低温处理，不需要高温烧成，具有抗渣、碱及铁水侵蚀、抗渗透性能优异的特点，缩短生产周期、降低成本。
