Low-temperature fired titanium-rich corundum composite silicon carbide brick and preparation method thereof
The invention discloses a low-temperature fired titanium-rich corundum composite silicon carbide brick and a preparation method thereof. The titanium-rich corundum composite silicon carbide brick is prepared from the following raw materials: 3-1mm brown fused alumina, 1-0mm brown fused alumina, 3-1mm titanium reinforced corundum, 1-0mm titanium reinforced corundum, 200-325 meshes titanium reinforced corundum, 200-325 meshes silicon carbide, silica fume, metal silicon micropowder and binding clay. In addition, a binding agent is added. Aggregate in the ingredients is mixed, and a mixed material A is obtained; mixing the fine materials to obtain a mixed material B, adding the mixed material A into the mixed material B, and mixing to obtain a total mixed material; and sequentially carrying out compression molding, drying and sintering on the total mixed material to obtain the titanium-rich corundum composite silicon carbide brick. The product provided by the invention has the characteristics of low firing temperature, slag, alkali and molten iron erosion resistance and excellent permeation resistance, is suitable for a lining refractory material for the bottom of a blast furnace hearth, and can reduce the raw material and manufacturing cost and the phenomenon of resource waste.
本发明公开了一种低温烧成富钛刚玉复合碳化硅砖及其制备方法。所述富钛刚玉复合碳化硅砖由原料3～1mm棕刚玉、1～0mm棕刚玉、3～1mm钛增强刚玉、1～0mm钛增强刚玉、200～325目钛增强刚玉、200～325目碳化硅、硅灰、金属硅微粉和结合粘土组成；另外加入结合剂。将配料中的骨料混合，得到混合物料A；细料混合得到混合物料B，然后将混合物料A加入混合物料B中混合，得到总的混合物料；将总的混合物料依次进行压制成型、干燥和烧成，得到富钛刚玉复合碳化硅砖。本发明产品具有烧成温度低、抗渣、碱及铁水侵蚀、抗渗透性能优异的特点，适用于高炉炉缸炉底用内衬耐火材料，可减少原料和制造成本以及资源浪费现象。
