细长工件如长轴、丝杠、光杠以及大型机床塞铁、剪刀板等,在热处理时,首先遇到的问题就是如何吊挂、装炉。此问题解决得好,不仅可保证加工质量,还可提高产量。但如考虑不周,不但影响生产任务的完成,而且还可能在热处理过程中发生工件掉落事故,使炉子损坏,或被迫停炉,给生产造成不应有的损失。 Slender workpiece such as the long axis, screw, light bar and large machine tool plunger, scissors, etc., in the heat treatment, the first problem encountered is how to hang, loading furnace. This problem is well resolved, not only to ensure the quality of processing, but also increase production. However, if the consideration is not good, it will not only affect the completion of production tasks, but also may cause a workpiece falling accident during heat treatment, causing the stove to be damaged or forced to shut down the stove, causing undue losses to production.
