随着科学技术的发展,要求能锻造出形状复杂、加工余量少的零件——即采用少无切削加工新工艺。电感应加热新工艺,虽能以极快的速度将锻坯加热到所需的锻造温度,从而减少锻坯的氧化,为实现少无切削提供有力措施,但由于缺少适当的测温手段,无法保证锻造质量,使这种新工艺的推广受到限制。用中频感应炉代替传统的加热方式,可达到使工件快速升温的目的。这时,由于热电偶响应时间长和受高频感应影响,不宜再用做测温工具。红外测温仪具有非接触和响应时间快的优点,是感应加热测温的合适手段。
With the development of science and technology, it is required to forge parts with complex shapes and low machining allowances - that is, to adopt a few new processes without cutting. Induction heating of the new technology, although the speed can be very fast forging billet heated to the required forging temperature, thereby reducing the oxidation of forging billet, in order to achieve less no cutting provide effective measures, but due to the lack of appropriate temperature measurement means can not Guarantee forging quality, so that promotion of this new technology is limited. Frequency induction furnace instead of the traditional heating methods, to achieve the purpose of rapid heating of the workpiece. At this time, due to the thermocouple response time and affected by the impact of high frequency, should not be used as a temperature measurement tool. Infrared thermometer has the advantages of non-contact and fast response time, is the appropriate means of induction heating temperature measurement.
