Sol-bonded high-temperature high-strength wear-resistant castable and application method thereof
The invention discloses a sol-bonded high-temperature high-strength wear-resistant castable, which is prepared from the following raw materials in parts by weight: 30-50 parts of 0.044-8mm corundum-mullite, 20-30 parts of 0.05-6mm industrial Si3N4-SiC, 2-6 parts of aluminum oxide less than or equal to 5mu m, 3-6 parts of 0.01-1mm of metal silicon powder, 4-12 parts of 0.02-5mu m of silicon oxide,10-20 parts of a binder, 4-8 parts of silica sol, and 0.1-0.3 parts of a stabilizer. The invention discloses an application method of a sol-bonded high-temperature high-strength wear-resistant castable. The application method comprises the following steps: (1) preparing materials; (2) crushing and grinding; (3) uniformly stirring to obtain a castable; (4) guiding the castable into a prefabricatedmold, and performing vibration compaction; and (5) naturally drying and curing for 8-24 hours, demolding, and then baking. In the application, Sialon is formed through solid solution between corundum-mullite and Si3N4-SiC, and permeation of aluminum oxide, silicon oxide and metal silicon powder is added, so that the castable has the characteristics of high strength, good wear resistance, good thermal stability and good corrosion resistance.
本发明公开了一种溶胶结合高温高强度耐磨浇注料，由以下重量份的原材料组成：刚玉‑莫来石0.044～8mm，30～50份，工业Si3N4‑SiC 0.05‑6mm，20‑30份，氧化铝≤5um，2～6份，金属硅粉0.01‑1mm，3‑6份，氧化硅0.02‑5um，4‑12份，结合剂10‑20份，硅溶胶4～8份，稳定剂0.1～0.3份。本申请一种溶胶结合高温高强度耐磨浇注料的应用方法，包括以下步骤：（1）备料；（2）粉碎研磨；（3）搅拌均匀，得浇注料；（4）将浇注料导入预制好的模具中，并进行振动密实；（5）自然干燥养护8‑24h后脱模，随后烘烤即可。本申请中，通过刚玉‑莫来石及Si3N4‑SiC之间固溶形成赛隆（Sialon），并加入氧化铝、氧化硅及金属硅粉的渗入，使得浇注料具备高强度、耐磨性良好、热稳定性良好、耐腐蚀性好良好的特点。
