对低公差,表面光亮,无脱碳高质量线材不断增长的需要,甚至对环境保护的严格控制,迫使所有工业线材生产厂和用户对完全能满足这些要求的热处理设备给予更多的考虑,必须明确阐明,在考虑高质量的同时也要有实在的经济效益。线材的主要热处理工艺是软化退火和晶粒细化,以便材料进一步加工。除去材料组织变化之外,几乎对所有热处理操作的共同要求是退火线材的表面尽可能不氧化。这样无需附加任何昂贵的酸洗或机械去除氧化皮的工序。
The growing need for low-tolerance, bright-surfaced, non-decalcified high-quality wire and even stringent environmental controls force all industrial wire producers and users to give more consideration to heat-treatment equipment that fully meets these requirements and must Clearly stated that in considering the high quality, but also have real economic benefits. The main heat treatment wire is softening annealing and grain refinement for further processing of the material. In addition to the changes in the microstructure of the material, the common requirement for almost all heat treatment operations is that the surface of the annealed wire should be as non-oxidizing as possible. This eliminates the need for any costly pickling or mechanical descaling steps.
