透明电热炉是近年来由美国麻省理工学院和日本株式会社寿电机制作所研制出的一项新设备,并于一九七九年三月和一九七九年七月由日本“电子技术”“应用物理”杂志分别发表了商品广告(技术指标见附录)。这种电热炉的主要优点是:炉体透明、升降温速率快、体积小、重量轻、耗电少、保温良好、性能稳定、成本低廉。它不但可给科研工作者提供在高温下直接观测工件位置,观察 Transparent electric furnace in recent years by the Massachusetts Institute of Technology and Japan Shou-Motor Manufacturing developed by a new device, and in March 1979 and July 1979 by Japan’s “Electronic Technology ”Applied Physics magazine published commercial advertising (technical indicators see appendix). The main advantages of this electric furnace is: furnace transparent, fast heating and cooling rate, small size, light weight, low power consumption, good insulation, stable performance, low cost. It not only provides scientific research workers with direct observation of workpiece position and observation at high temperature
