Ib qho hlau alloy uas nws cov khoom tseem ceeb yog titanium thiab hlau. Nws kuj muaj cov impurities xws li txhuas, silicon, carbon, sulfur, phosphorus, thiab manganese. Siv ua deoxidizer, desulfurizer, degassing tus neeg saib xyuas thiab tus neeg sawv cev alloying hauv steelmaking. Nws tau ntxiv rau cov hlau ua cov khoom siv alloying thaum lub sij hawm steelmaking txheej txheem los kho cov qauv nplej, kho cov ntsiab lus interstitial (C, N), thiab txhim kho lub zog ntawm cov hlau.
ferro titanium hlau
Ib qho hlau alloy uas nws cov khoom tseem ceeb yog titanium thiab hlau. Nws kuj muaj cov impurities xws li txhuas, silicon, carbon, sulfur, phosphorus, thiab manganese. Siv ua deoxidizer, desulfurizer, degassing tus neeg saib xyuas thiab tus neeg sawv cev alloying hauv steelmaking. Muaj peb yam tseem ceeb raws li cov ntsiab lus titanium: FeTi30 (muaj Ti25.0% ~ 35.0%, Al<8.5%, Si<5.0%), FeTi40 (containing Ti35.0%~45.0%, Al<9.5%, Si<4.0%) and FeTi70 (containing Ti65%~75%, A10.5%~5%, Si<0.5%). In addition, there are a variety of titanium-containing composite alloys such as Ti-Si-Fe, Ti-B-Al-V, Ti-B-Al-Cr, Ti-Al, Ni-Ti-Al, Ti-B-Al, Ti -Cr-Al, etc., used as titanium additives.
Ferro Titanium Alloy
Titanium tau tshawb pom los ntawm W. Gregor hauv 1791, tab sis tsis muaj npe thaum lub sijhawm. Nws tsis tau lub npe hu ua "Titans" kom txog rau thaum MH Klaproth nrhiav tau titanium nyob rau hauv 1795. A. Rossi tau thov ib tug patent rau electro-aluminothermic txoj kev ntawm smelting ferro-titanium nyob rau hauv 1901. Nyob rau hauv 1937, lub Soviet Union tau kawm cov txheej txheem ntawm smelting ferro-titanium siv. txoj kev thermite. Los ntawm nruab nrab -1950s, vim qhov nce hauv cov khoom siv hlau titanium, ferrotitanium nrog 70% Ti pib tsim. Tuam Tshoj pib tsim ferrotitanium ntawm kev lag luam nplai siv cov txheej txheem thermite ntawm Jinzhou Ferroalloy Factory hauv xyoo 1959.
