鱼雷罐喷补料的研制开发与应用

以致密高铝矾土、碳化硅、白刚玉细粉、SiO2微粉、Al2O3微粉和纯铝酸钙水泥等为原料,开发了鱼雷罐喷补料,研究了微粉加入量对喷补料性能的影响,比较了氯化钙、聚合氯化铝、三乙醇胺、铝酸钠的促凝效果.结果表明,加入7％的SiO2微粉和3％的Al2O3微粉,对提高施工性能和使用性能有利；以三乙醇胺为促凝剂有较好的促凝效果.开发的喷补料在鱼雷罐大修时一次喷补,可提高鱼雷罐使用寿命200次以上,喷补工艺简单、施工性能好,吨铁降成本约0.3元.

Deve1opment and Application of the Jetting Refractory for Torpedo Ladle

The jetting refractory for torpedo ladle was developed by density bauxite,silicon carbide,white corundum powder,fine silica powder,fine alumina powder and pure calcium aluminate cement as material.The influences of the fine powers on the properties of the jetting refractory were investigated.And the accelerating effects of CaCl2,polyaluminium chloride,triethanolamine and NaAlO2 were compared.The results showed that adding 7% fine SiO2 powder and 3% fine Al2O3 powder was beneficial to the construction performance and using performance of the gunning refractory and the triethanolamine had better accelerating effect.The developed jetting refractory increased the life of torpedo ladle for more than 200 times for once when the torpedo ladle was overhauled.The jetting process is simple and the construction performance is good.The cost of per ton iron was decreased by 0.3 Yuan(RMB).
