涉及一种焊管用钛带卷的罩式退火炉退火工艺。具体步骤如下:1将钛带卷放入罩式炉内;2加热罩点火加热,根据炉内热电偶所测温度通过加热罩上的烧嘴对退火温度进行控制;3升温到400~450℃保温2~4 h;4升温到530~570℃保温3~5 h;5升温到600~700℃保温4~10 h;6冷却至200℃以下;7将钛卷出炉送下道次工序。采用本退火工艺退火,可使
Involving a titanium tube with a roll annealing furnace annealing furnace. The specific steps are as follows: 1 the titanium coil into the hood furnace; 2 heating hood ignition heating, according to the temperature measured by the furnace thermocouple through the heating cover of the burner on the annealing temperature control; 3 heated to 400 ~ 450 ℃ Keeping the temperature for 2 to 4 hours; 4, raising the temperature to 530-570 DEG C for 3 to 5 hours; 5 raising the temperature to 600-700 DEG C for 4 to 10 hours; 6 cooling to below 200 DEG C; Annealing using the annealing process can be
