退火是金属纤维生产过程中最为关键的环节,对金属纤维性能有着重要的影响。传统生产工艺下,数百公斤的复合体装入炉罐,通入保护气体,在井式炉中加热炉罐,进而完成复合体的退火过程。该方法升、降温速率较低,使得复合体在敏化温度区间停留时间过长,从而造成纤维表面碳化物的析出,给纤维性能带来极坏影响。另外,炉罐内温度分布不均,造成复合体退 Annealing is the most crucial part of the metal fiber production process, and has an important impact on the performance of metal fibers. Traditional production process, hundreds of kilograms of complex into the furnace, the introduction of protective gas, furnace furnace in the pit furnace, and then complete the complex annealing process. The method has the advantages of low cooling rate and long residence time of the complex in the sensitization temperature range, thereby causing the precipitation of carbides on the fiber surface, which has a very bad influence on the fiber properties. In addition, uneven temperature distribution within the furnace, resulting in complex retreat
