The utility model discloses a gas heat treatment system, including argon protection control system and mixed heating system, the argon protection control system includes argon tank 1 and argon pipeline 2, the argon in argon tank 1 is through pressure and flow control and is passed into different argon pipeline 2, and pressure and flow control are controlled respectively through automatic valve 6 and pressure gauge 5. Divide micro-positive-pressure argon and high pressure argon, the micro-positive-pressure argon is introduced into crucible 3, the high pressure argon is introduced into heat treatment coil, the mixed heating system is used to preheat micro-positive-pressure argon and high pressure argon, and the argon is controlled through flow and pressure, and is divided into two paths, one path is micro-positive-pressure argon, and the argon in this pipeline is introduced into crucible 3, and the coil is maintained in a stable temperature range, the other path is high pressure argon, and the high pressure argon is introduced into the heat treatment coil, and the purpose is also to maintain the coil in a stable temperature range, both paths of argon have the effect of removing gas impurities generated in the heat treatment process, avoid the problems of inaccurate temperature control and poor uniformity of the temperature in the furnace, and improve the heat treatment effect and final performance of the coil material.

[0017] In order to make two paths of argon be introduced into respective preheaters, referring to the drawing, Figure 1As shown, the argon protection control system further comprises a heat exchanger 4, a pressure gauge 5 and an automatic valve 6, the argon pipeline 2 is connected with the argon tank 1, the heat exchanger 4 and the vertical gas furnace 7, the argon pipeline 2 is further connected to the crucible 3 in the vertical gas furnace 7, realizing the circulation of argon, according to the temperature curve and the monitored abnormal situation, making the feedback response, ensuring the temperature curve required by the coil, the automatic valve 6 is used for controlling the flow of argon, and the pressure gauge 5 is used for monitoring the pressure of argon. According to the different functions of the two argon, the part of the heated argon is divided into two parts, and the two parts are introduced into the respective pre-heaters. The hot heater is a spiral pipe installed outside the crucible 3, and the spiral pipe is arranged in the vertical furnace. The high-temperature gas in the vertical furnace preheats the argon first, so that the outlet temperature of the argon reaches the required temperature. The mixed heating system comprises a natural gas heating system and an electric heating system. The electric heating system comprises a thermocouple 9 arranged outside the vertical gas furnace 7 and an electric heating pipeline 8. The electric heating system is used for heating the micro-positive-pressure argon. The preheated argon is compensated by the micro-positive-pressure and high-pressure electric heating compensators respectively, so as to achieve the purpose of accurate temperature control and rapid response. The argon discharged from the coil and the crucible 3 is cooled and then tested according to requirements. The coil needs to meet the requirements of heat treatment time, temperature curve, temperature uniformity and gas impurity content. The electric heating pipeline 8 heats the micro-positive-pressure argon through the thermocouple 9. Because the gas impurities in the winding coil and the crucible 3 are different, and the argon in the winding is high-pressure argon, the argon discharged from the winding can be considered to be introduced into the micro-positive-pressure argon inlet pipeline after cooling and testing, so as to save argon. The natural gas heating system comprises a burner 10 arranged on the vertical gas furnace 7. The natural gas is burned through the burner 10. The generated gas forms a spiral flow throughout the whole furnace body in the vertical gas furnace 7.

The micro-positive-pressure argon introduced into the crucible 3 is heated by the electric heating after preheating. The thermocouple 9 is located outside the vertical furnace, and the pipeline has heat preservation material for heat preservation. After the argon is preheated, the temperature approaches the required temperature of the coil. The electric heating is compensated by the accurate control of the thermocouple 9, so that the temperature meets the requirements of the coil and the temperature uniformity of the coil. The argon introduced into the coil needs to be connected in parallel with four groups of the same coil. After the high-pressure argon is preheated by the gas, the temperature approaches the required temperature of the coil. The temperature is compensated by the electric heating, so that the temperature reaches the required temperature.
