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 1 500℃,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%.
Titanium-containing Blast Furnace Slag Produced Titanium-silicon-aluminum Alloy by Aluminothermic Reduction
This is an article in the field of metallurgical engineering.At the protection of argon gas,titanium-containing blast furnace slag produced titanium-silicon-aluminum alloy by aluminothermic reduction.The test result shows at 1 500℃,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.
