比利时设计的钢丝奥氏体化热处理明火加热炉(FIB),由于加热方式的改进,加热速度快,能利用余热,金相组织晶粒状态良好,故国外普遍采用 FIB 处理钢丝。此型炉数量已达二百五十余座,理由是其炉内气氛能精调,产量匹配一致,维护简便,耗能 Belgium designed austenitizing heat treatment wire furnace (FIB), due to the improvement of heating method, heating speed, the use of waste heat, the grain morphology of the metallographic structure is good, it is widely used in foreign FIB wire. The number of this type of furnace has reached more than 250 seats, on the grounds that the furnace can be fine-tune the atmosphere, consistent output matching, easy maintenance, energy consumption
