Non-cracking anti-erosion high-aluminum castable and application thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a non-cracking anti-erosion high-aluminum castable and application thereof.The non-cracking anti-erosion high-aluminum castable is prepared through the following steps: 1, pouring main materials and additives are proportionally added into a blender mixer, and pouring pug is prepared; (2) a forming mold is manufactured and placed in an equipment iron shell to be placed on a vibration platform; (3) an anti-explosion fiber layer and a heat preservation layer are arranged in the equipment iron shell; (4) pouring pug is injected, compaction forming is carried out, and a refractory lining green body is prepared; (5) the forming mold is taken down, the inner side of the green body is maintained, and redundant pouring pug is scraped away; 6) low-temperature heat treatment is performed on the green body; and 7) the green body is sintered to obtain a finished product. And 8) finished products are randomly sampled and detected. The casting main material is prepared from flint clay aggregate, rho-aluminum oxide, dispersed aluminum oxide, fiber powder, white corundum and a composite additive; and the composite additive is composed of cryolite, explosion-proof fiber and pure calcium aluminate cement. The refractory material prepared from the castable is compact in internal structure, has good thermal shock resistance, aluminum adhesion resistance and erosion heat resistance, and is not easy to crack.
本发明属于耐火材料技术领域，具体涉及一种不开裂抗侵蚀高铝浇注料及其应用，包括如下步骤：1)浇注主料和外加剂配比加入混料机，制成浇注泥料；2)制作成型模具置于设备铁壳内部放到振动平台上；3)设备铁壳内设防爆纤维层和保温层；4)注入浇注泥料，振实成型，制得耐火内衬坯体；5)取下成型模具，坯体内侧养护，刮除多余浇注泥料；6)坯体低温热处理；7)坯体烧结，制得成品；8)随机取样成品检测。浇注主料由焦宝石骨料、ρ‑氧化铝、分散型氧化铝、纤维粉、白刚玉和复合添加剂组成；复合添加剂由冰晶石、防爆纤维和纯铝酸钙水泥组成。采用该浇注料制作的耐火材料内部组织致密，具有良好的抗热震、不粘铝和抗侵蚀热，不易开裂。
