摘　　要：这是一篇冶金工程领域的文章。在氩气保护下,用铝还原含钛高炉渣制得钛硅铝合金。实验结果显示:在1500℃,氩气保护下,铝粉占高炉渣的30%~40%、石灰占5%~15%、萤石≥5%时,还原得到的合金主要为钛硅相、铝硅相、钛相;合金中钛、硅、铝的含量为分别35%~40%、26%~33%、23%~32%,钛、硅、铝的回收率分别为73%~88%、84%~95%、67%~77%。This is an article in the field of metallurgical engineering.At the protection of argon gas,titaniumcontaining blast furnace slag produced titanium-silicon-aluminum alloy by aluminothermic reduction.The test result shows at 1500℃,at the protection of argon gas,when aluminum powder accounts for 30%~40%of blast furnace slag,lime accounts for 5%~15%and fluorite≥5%,the alloys obtained by reduction are mainly titanium-silicon phase,aluminum-silicon phase,titanium phases.In the alloy,the content of titanium,silicon,aluminum were 35%~40%,26%~33%,23%~32%,respectively.The recoveries of titanium,silicon,aluminum were 73%~88%,84%~95%,67%~77%,respectively.
