Resistance Furnace Temperature Control System Design

Heat treatment is a main means of improving metal material and metalwork. In recent yeas, with the development of industry, there are more and more supernal request for metalwork, so heat treatment is hammering at high quality and efficient, low-power and zero-social effects of pollution. Resistance furnace is a used broadest heating equipment in heat treatment, and measurement and control of temperature in heating is becoming pivotal technic. These urge people study methods of controlling heating process.In this thesis,using the temperature control system of laboratory resistance furnace as the background to describe the technological transformation of the old equipment. Based on basic experimental conditions, we design the Distributed Control System(DCS). Host computer plays the role of monitoring and information management. Slave computer realizes basic control, data acquisition, control output, real-time display and communication functions. MCS-51 Single-Chip Microcomputer as a processor, the modified temperature controller possess automatic detection, real-time data acquisition and real-time display. The modified temperature improves stability and control precision, The control panel of temperature control system is very concise and convenient.The modified temperature control system satisfies technical requirements.
