目前,一般企业热处理所用的控温设备较陈旧,炉子配用的仪表和控制柜,多数是电炉生产厂家的常规产品,例如用带位式调节的EWY、XWB、XWC型电子电位差计和GLC-BD型控制柜。由于炉温波动幅度达10～20℃,难以满足对温度参数有严格要求的热处理工艺(如铝合金焠等)。更为令人担心的是,由于继电器剩磁,触点沾接等疵病而导致工件过烧、跑温等。为此,我们研制了一台杜绝跑温事故的精密控温装置。该装置带有TA-031型或TA-041型电子调节仪表来控制温度,以提高调温品质,解决了加热时的超调现象。原配的电子电位差计作为记录和报警之用。在运行中,如果主控仪表失控,副控仪表便自动承
At present, the general temperature control equipment used in business heat treatment older than the furnace with the use of instruments and control cabinets, most of the conventional products are electric furnace manufacturers, such as with the position adjustment EWY, XWB, XWC-type electronic potentiometer and GLC -BD type control cabinet. As the furnace temperature fluctuations of 10 ~ 20 ℃, it is difficult to meet the strict requirements of the temperature parameters of heat treatment process (such as aluminum quenching, etc.). Even more worrying is that due to relay residual magnetism, contact stained and other defects caused by the workpiece over-burning, running temperature and so on. To this end, we developed a precision temperature control device to eliminate running accidents. The device with TA-031 or TA-041-type electronic regulation instrument to control the temperature, in order to improve the quality of temperature control to solve the overshoot phenomenon when heated. The original electronic potentiometer as a record and alarm purposes. In operation, if the master instrument out of control, Vice-control instrument will automatically bearing
