本文研究了离子轰击加热时工件的温度不均匀性问题。试验证明:影响温度不均匀性的主要因素是工件的形状因素。工件不同形状部位的温度差别是由于工件不同形状部位电流分布及散热条件不同而造成;在普通离子氮化炉中增设封闭隔热层的方法,可以基本解决离子轰击加热工件温度的不均匀性问题,而且可以大大节省能源,使在不同温度保温时所需单位表面积上功率消耗降低65%～80%。此外,由于该种方法仍用离子轰击单一加热的方法,因而保持了离子轰击化学热处理速度快速一特点。
This paper studies the temperature nonuniformity of workpiece during ion bombardment heating. Tests show that: the main factor affecting the temperature non-uniformity is the workpiece shape factors. Different parts of the workpiece temperature difference is due to different parts of the workpiece current distribution and cooling conditions caused by different; ordinary ion nitriding furnace to add a closed insulation layer method can basically solve the problem of ion bombardment heating the workpiece temperature non-uniformity , But also can greatly save energy, so that when the temperature at different temperatures per unit surface area required to reduce power consumption 65% to 80%. In addition, due to the method of ion bombardment with a single heating method, thus maintaining the ion bombardment chemical heat treatment speed a feature.
