为稳定连续退火酸洗线生产的建筑用纯钛表面光泽度，研究了炉内氧气浓度和退火时间对酸洗纯钛表面光泽度的影响，结果表明：3%O2退火后的表面光泽度低于5%和10%O2退火后的表面光泽度。当氧浓度低时，形成难以通过在熔融盐浴中浸渍去除的细小氧化皮，因此难以酸洗，降低了总质量。当退火时间短时，光泽度低，晶粒生长不充分，增加了表面上酸洗纯钛的峰的数量。将这些发现应用到APL操作中，可以精确控制建筑用纯钛的光泽度。
The effect of oxygen concentration in the furnace and annealing time on the gloss of pickled pure titanium was studied to stabilize the gloss of pure titanium for construction manufactured by the continuous annealing and pickling line (APL).The gloss of pickled pure titanium annealed in 3% O2 was lower than that annealed in 5% or 10% O2. When the oxygen concentration was low, fine scale formed that was difficult to remove by dipping in a molten salt bath and thus difficult to pickle, lowering gross. Gloss was low when annealing time was short, and grain growth did not occur sufficiently, increasing the number of peaks of pickled pure titanium on the surface. Applying these findings to APL operation made it possible to control precisely the gloss of pure titanium for construction.
