调整部分功率式控温,介于“通、断”式调节与“连续”式调节之间,它基本吸取了二者的长处,具有调节简单(用“位”式仪表),升温快,定温准,炉内电流连续且变化率小,温度波动较小,热冲击、电磁场冲击较小等优点。特别适合加热周期较短(几分钟至十几分钟)的工具热处理。它的基本特征就在于只调整馈入功率中的一小部分。采用可控硅技 Adjust some of the power temperature control, between the “on and off” regulation and “continuous” regulation between, which basically absorbed the strengths of both, with easy regulation (with “bit” instrument), warming fast, constant temperature Accurate, continuous current in the furnace and the rate of change is small, less temperature fluctuations, thermal shock, electromagnetic field impact and smaller advantages. Particularly suitable for heating cycles shorter (minutes to ten minutes) tool heat treatment. Its basic feature is that only a small part of the feed power is adjusted. Using SCR technology
