在线光亮固溶退火设备简称光亮退火，是对高标准要求管材进行在线处理的必备设备。光亮退火设备是将焊管在线加热到1050℃，随后置于氢气保护下快速冷却至100℃以下。

On-line bright solution annealing equipment referred to as bright annealing, is a high standard requirements of the necessary processing equipment on-line equipment. The bright annealing equipment is heated to 1050 ° C on-line and then quickly cooled to below 100 ° C under hydrogen protection.

在线光亮退火采用中频感应加热电源，电源为新型DSP+IGBT结构设计，采用DSP全数字化控制系统，设置有完善的自保护、自诊断功能，具有体积小、升温快、、节能等特点。

On-line bright annealing using medium frequency induction heating power supply, power supply for the new DSP + IGBT structure design, the use of DSP digital control system, set a perfect self-protection, self-diagnostic function, with small size, fast heating, efficient, energy saving and so on.

在线光亮退火流程/Online bright annealing process：

当管材进入设备后，利用卡件进行进口封闭，然后向设备内充进惰性气体将空气排空，管材在经过加热炉时，通过中频电流流过的线圈，从而对管材进行退火处理，加热炉与冷却筒之间用石英管连接，防止进入空气，管材在冷却筒中与惰性气体反应，恢复管材本身亮度，在冷却筒出口处通过密封卡件穿出，即完成整个加工过程。

When the pipe into the equipment, the use of card accessories imported closed, and then filled with inert gas into the equipment to empty the air, the pipe through the furnace, through the IF current through the coil, so the pipe annealing, heating furnace And the cooling tube connected with a quartz tube to prevent access to the air, the pipe in the cooling cylinder with the inert gas reaction to restore the brightness of the pipe itself, at the exit of the cooling tube through the sealing card piercing, that is completed the entire process.
