Changer switch: The changeover switch is an electric quick change switch used in medium frequency electric furnace: easy to operate, safe and reliable 

The utility model has the advantages of convenient use, shortening the switching time of the furnace, improving the efficiency, reducing the labor intensity of the worker, and easily realizing the switching of the intermediate frequency power source to the heat preservation furnace body and the melting furnace, and has great practicality.

 Automatic constant temperature function: The furnace water temperature requirement range value can be preset, and the one-key start can realize the automatic constant temperature purpose; compared with the traditional manual control temperature, the automatic constant temperature function will save time and trouble, be more sensitive and accurate, and the furnace water temperature will be more Easy to control, less oxidative burning loss, better quality of metal components and even casting products;

 Automatic oven function: The oven is a relatively complicated and long-term curve heating process. It is necessary to prolong the service life of the intermediate frequency furnace and reduce the production cost. It is very important to build the furnace oven correctly. The company's innovative automatic oven function can pre-set the time and temperature required for different oven stages according to the oven temperature requirements of different furnace lining refractories; one-button start according to the preset time and temperature of PLC Automatic matching does not control the size of the intermediate frequency power, control the heating rate, prevent cracks in the lining, and achieve the purpose of automatic curve oven. That is to avoid manual misuse and reduce the labor time and intensity of workers.

 Anti-wearing furnace alarm function: Hengyang's unique double anti-wearing furnace alarm function adopts dual combination detection of differential current mode and DC injection type. Provides an extremely reliable leak protection for the furnace system and all-round rapid protection of any ground fault. The detection system has an early warning function. When the furnace lining is thinned to a certain extent, an alarm light alarm will be made in advance to remind the user that the life of the lining will be reached, and the purpose of safe production is predicted in advance. Solve the trouble of the customer because it has been used until it can not be turned on, and the furnace has material and cannot continue to melt.

 Furnace weighing function: According to the customer's demand, the weighing system can be installed in the furnace body, and the weight data of the molten iron can be transmitted to the operating platform PLC , and displayed through the touch screen, which is convenient and intuitive to reflect the weight of the current molten body in the furnace body. The operator makes component adjustments and production schedules. At the same time, the system can also be automatically melted . According to the formula of each grade material, it can automatically control the weighing and distribution of the charge, the error automatic compensation, the automatic alarm of the tolerance, the printing and recording of the batching data, the high precision and fast speed of the ingredients; the accurate ingredients ensure the stable composition of molten iron, and the quality of production is high. Hot metal provides a strong guarantee!

 Furnace lining structure: Once the furnace temperature is cooled to below 400 °C, the furnace body is turned to 90 degrees, the crane is lifted and pushed out, and the cylinder connection flange is placed in the pre-designed rail at the bottom of the furnace body to start the hydraulic pump station. , easily launch the lining. Reduced work intensity and improved work efficiency.
