Constant temperature control system for aluminum bar heating

The invention relates to the technical field of extrusion processing, in particular to a constant temperature control system for aluminum bar heating. According to the technical scheme, the constant-temperature control system for aluminum bar heating acts on an aluminum bar extruder and comprises a control center, a temperature control module and a speed control module, the temperature control module and the speed control module are regulated and controlled by the control center, and the temperature control module and the speed control module give negative feedback to the control center; and the temperature control module comprises a thermodetector used for detecting the temperature of a mold outlet of an aluminum bar and a modeling simulation unit used for receiving a temperature measurement result of the thermodetector and carrying out overall modeling on the extruded aluminum bar, the control center comprises an analysis processing unit used for receiving temperature distribution simulation information fro
