在盐浴炉加热中,温度的高低、保温时间的长短直接影响工作的质量。我们在盐浴炉上加上了工艺记时器,解决因人为因素不能准确掌握保温时闻的问题,保证了零件的热处理质量。一、工艺记时器的结构及控制该工艺记时器是由两只时间继电器,一只接触器,一只中间继电器,两只按钮开关,一只电铃,三只指示灯组成。时间继电器、指示灯、按钮开关装在面板上,其余装在铁盒内。用220V交流电源。电气原理见附图。根据工艺将面板上的时间继电器调整到所需的时间。当盐浴到温
Salt bath furnace heating, the level of temperature, the length of the holding time directly affect the quality of work. We add the craft chronograph on the salt bath stove to solve the problem that the temperature can not be accurately grasped because of the human factor and the heat treatment quality of the part is guaranteed. First, the structure and control of the craft chronograph The craft chronograph is composed of two time relay, a contactor, an intermediate relay, two button switches, an electric bell, three indicator lights. Time relay, light, button switch mounted on the panel, the rest installed in the tin box. With 220V AC power. See the attached electrical principle. Depending on the process, adjust the time relay on the panel to the desired time. When the salt bath to warm
