Abstract. The production of raw titanium metal relies on natural and man-made feed materials, including natural rutile, titanium dioxide slags of different grades ("chloride slag," UGS, and "sulfate slag"), and synthetic rutile. Natural rutile was the feedstock of choice at the early years of the Kroll process, but nowadays it comes in ...

In the production line, molten slag was discharged from a furnace that included an atomization system. Due to atomizing, BOF slag solidified into droplets and granules. The entire BOF slag () passed through a 10 mm sieve and none of it passed through a 2.5 mm sieve, which is general ranges of atomized slag [29], [30]. ...

GMAW lacks slag coverage and has higher deposition rates than FCAW or shielded metal arc welding (SMAW). The lack of slag coverage has a noticeable effect on the weld cooling rate, although welds made using GMAW are more likely to exhibit solidification lines due to the higher travel speeds, which intensify a faster cooling rate.
