在热电偶退火处理中,目前多是采取人工调节温度,控制退火时间。这种方法虽然简单,但调节麻烦,形式落后。本文介绍一种热电偶退火自动化装置。一、自动化装置的结构热电偶在空气中退火有通电退火和炉中退火两种方法,该自动退火装置应能满足这两种退火方法的要求,并能保证热电偶按照确定的时间退火,使其金相组织完全、充分地完成转变、扩散过程。这除了控制一定的保温时间以外,还要有适当的升温和降温时间。因此装置中应包括:程序给定器、PID连续调节器、温度显示记录仪、电流转换器、可控硅电压调整器、可控硅元件、退火炉及退火柜等。退火运
In the thermocouple annealing process, the current is to manually adjust the temperature to control the annealing time. Although this method is simple, but the adjustment of trouble, the form of backwardness. This article describes a thermocouple annealing automation device. First, the structure of the automation device Thermocouple annealed in air energized annealing and furnace annealing two methods, the automatic annealing device should be able to meet the requirements of these two annealing methods, and to ensure that the thermocouple annealed at a determined time, so that Its metallurgical organization completely and fully completed the transformation and diffusion process. This in addition to controlling the holding time, but also have appropriate heating and cooling time. Therefore, the device should include: program setter, PID continuous regulator, temperature display recorder, current converter, SCR voltage regulator, SCR components, annealing furnace and annealing cabinet.
