The invention provides a control device for a natural gas high-temperature heat treatment furnace. The natural gas high-temperature heat treatment furnace comprises a furnace body and multiple natural gas branch pipes connected to the furnace body; the control device comprises a shell, a man-machine control panel and a main control panel; the shell is arranged on the outer side of the natural gas high-temperature heat treatment furnace, the man-machine control panel is arranged on the shell, the main control panel is arranged in the shell and is electrically connected with the man-machine control panel, a PLC and a PLC main control peripheral circuit are integrated on the main control panel, and multiple temperature sensors are further distributed in the furnace body; each natural gas branch pipe is further provided with a flow valve, a pressure sensor and a flow sensor; the PLC is electrically connected with the multiple temperature sensors, the multiple pressure sensors, the flow sensors and the flow valves, and the flow valves are regulated and controlled according to data of the temperature sensors, the pressure sensors and the flow sensors. According to the technical scheme, the flow of the multiple natural gas branch pipes can be stable, and it is ensured that the temperature in the furnace is uniform.
Description
technical field [0001] The invention relates to the technical field of heat treatment furnaces, in particular to a control device for natural gas high temperature heat treatment furnaces. Background technique [0002] Heat treatment furnace refers to the electric furnace or fuel furnace used for heat treatment and heating of charge. Existing heat treatment of castings, commonly used natural heat gas heat treatment furnace. When the natural gas heat treatment furnace heats the castings, the flow of natural gas is unstable, and the temperature in the furnace is uneven, which leads to uneven heating of each casting and affects the processing efficiency. There is no effective solution to this. Contents of the invention [0003] Based on at least one of the above technical problems, the present invention proposes a new control device for natural gas high-temperature heat treatment furnace. The overall structure design is reasonable, which can stabilize the flow of multiple nat...
