Lining compact material for plasma furnace and preparation method of lining compact material
The invention discloses a lining compact material for a plasma furnace. The silicon carbide ceramic material is prepared from the following components in percentage by mass: 20 to 30 percent of calcium hexaluminate fine powder, 3 to 6 percent of silicon powder, 6 to 7 percent of aluminum powder, 0.5 to 1.5 percent of titanium dioxide powder, 1 to 2 percent of aluminum oxide powder, 0.5 to 1.5 percent of silicon dioxide powder, 1 to 2 percent of vanadium carbide fine powder, 0.05 to 0.1 percent of toughening agent, 0.3 to 0.5 percent of pore forming agent, 7 to 8 percent of binding agent and the balance of silicon carbide powder, the preparation method comprises the following steps: S1, mixing the raw materials; s2, spark plasma sintering is carried out; s3, alternate dipping; s4, heat treatment; according to the lining compact material, silicon carbide and calcium hexaluminate are compounded to prepare a porous compact material by adding the pore-forming agent, so that the internal compactness of the material is improved, and the material has excellent slag corrosion resistance; and by adding a small amount of toughening agent, the fracture resistance and thermal shock resistance of the material are improved while the compactness of the material is improved.
本发明公开了一种等离子炉用的内衬致密材料，按质量百分比计包括以下组分：20～30％的六铝酸钙细粉、3～6％的硅粉、6～7％的铝粉、0.5～1.5％的二氧化钛粉、1～2％的氧化铝粉、0.5～1.5％的二氧化硅粉、1～2％的碳化钒细粉、0.05～0.1％的增韧剂、0.3～0.5％的造孔剂、7～8％的结合剂以及余量的碳化硅粉体；其制备方法包括以下步骤：S1、混合原料；S2、放电等离子烧结；S3、交替浸渍；S4、热处理；本发明内衬致密材料通过添加造孔剂使碳化硅与六铝酸钙复合制成多孔致密材料，提高材料内部致密度，从而具有优异的抗渣侵蚀性；并且通过添加少量增韧剂，在提高材料致密性能的同时提高材料的抗断裂性和抗热震性。
