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.

在線光亮退火采用中頻感應加熱電源，電源為新型DSP+IGBT結構設計，采用DSP全數字化控制系統，設置有完善的自保護、自診斷功能，具有體積小、升溫快、高效、節能等特點。

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.

在線光亮退火流程/online bright annealing process：

當管材進入設備后，利用卡件進行進口封閉，然后向設備內充進惰性氣體將空氣排空，管材在經過加熱爐時，通過中頻電流流過的線圈，從而對管材進行退火處理，加熱爐與冷卻筒之間用石英管連接，防止進入空氣，管材在冷卻筒中與惰性氣體反應，恢復管材本身亮度，在冷卻筒出口處通過密封卡件穿出，即完成整個加工過程。

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.
