Description
「ストリップ(1)の搬送路(2)に沿って配置されたストリップ(1)の装入側冷却領域(3)と、装入側冷却領域(3)に続いて設けられ、内部温度が焼鈍温度に保たれた焼鈍領域(4)と、焼鈍領域(4)の後に設けられたストリップ(1)の搬出側冷却領域(5)と、焼鈍領域(4)と搬出側冷却領域(5)を連結する中間領域(6)と、還元性雰囲気ガス(10a)を炉内に供給するガス供給装置(7)とで構成された連続式光輝焼鈍炉(A)にて装入側冷却領域(3)の装入口(12)及び搬出側冷却領域(5)の搬出口(14)から炉内の還元性雰囲気ガス(10a)(10b)を放出しつつストリップ(1)を還元性雰囲気内で連続的に光輝焼鈍する方法であって、
装入口(12)より搬出口(14)の炉内ガス排出抵抗を小さくし、且つ、ガス供給装置(7)の装入側ガス供給口(8)を装入側冷却領域(3)に接続して、供給された還元性雰囲気ガス(10a)を装入側冷却領域(3)から焼鈍領域(4)方向に流すと共に、
中間領域(6)にガス供給装置(7)の分岐ガス供給口(9)が更に接続され、分岐ガス供給口(9)から供給された還元性雰囲気ガス(10a)を搬出側冷却領域(5)方向に流す」ことを特徴とする。
