Embodiment Construction
[0015] figure 1 It schematically shows a furnace temperature control system for a vacuum gas quenching furnace according to an embodiment of the present invention. Such as figure 1 As shown, the furnace temperature control system of the vacuum gas quenching furnace includes an interlayer 2 coated on the side wall of the furnace body 1, a cooling water system and a control system. The cooling water system includes a water inlet pipe 51 , a water outlet pipe 52 , a first manual solenoid valve 61 , a second manual solenoid valve 62 and a solenoid valve 7 .
[0016] The interlayer 2 is communicated with a water inlet pipe 51 and a water outlet pipe 52 respectively. The bottom of the interlayer 2 is provided with a first water inlet 21 , a second water inlet 22 and a third water inlet 23 . The first water inlet 21 , the second water inlet 22 and the third water inlet 23 are located on a straight line. The first water inlet 21 is far away from the furnace door 11 . The third wa...

The invention discloses a temperature control system for a furnace body of a vacuum gas quenching furnace. The temperature control system comprises a sandwich and a control system of a cooling water system, wherein the cooling water system comprises a water inlet tube and a water outlet tube; the water inlet tube separately communicates with a first water inlet, a second water inlet and third water inlets of the sandwich; the water outlet tube communicates with three water outlets; a first manual solenoid valve is arranged on a pipeline for communicating the water inlet tube to the first water inlet; a second manual solenoid valve is arranged on a pipeline for communicating the water inlet tube to the second water inlet; a solenoid valve is in parallel connected on a pipeline for communicating the water inlet tube to the second water inlet; a first temperature measuring thermal resistor is arranged on the bottom of the sandwich; a second temperature measuring thermal resistor is arranged on the top of the sandwich; a thermometer is arranged on a furnace door; and the control system is separately connected with the solenoid valve, the thermometer, the first temperature measuring thermal resistor and the second temperature measuring thermal resistor. According to the temperature control system disclosed by the invention, the temperature in the furnace body is controlled by cooling water in the sandwich, so that condensation, inside a furnace wall as a result of plates and the like, of water vapor can be effectively reduced, and therefore, quality of tapped products is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of metal heat treatment equipment, and more specifically designs a furnace temperature control system for a vacuum gas quenching furnace for heat treatment. Background technique [0002] With the improvement of mechanical industry products' requirements on metal surface properties and the environmental protection awareness of the whole society, more and more product manufacturers choose vacuum heat treatment equipment. Among them, vacuum gas quenching is an ideal process technology for improving the surface shape of metal parts or raw materials. Especially for some special parts and materials used in aerospace and microelectronics technology, vacuum quenching is required to meet the requirements. Since the user of the equipment has high requirements on the surface properties of the baked products and needs to ensure the stability of the surface properties of the baked products, the vacuum degree is high duri...
