Technological Advantages:

Tilting Cylinder System: Includes a hydraulic pump station and a tilting control panel. Designed for full-load tilting, it consists of a hydraulic pump and drive motor, emergency pump, motor starting device, oil tank, return oil and suction oil filter (with explosion-proof valve). Tilting, stopping, and resetting of the furnace are achieved via buttons and handles on the hydraulic control panel. The furnace can be tilted 95 degrees by the hydraulic cylinder, emptying all molten metal, and can stop at any position during the tilting process as needed.

Automatic temperature control function: The required range of furnace water temperature can be preset, and one-button start can achieve automatic temperature control. Compared with traditional manual temperature control, the automatic temperature control function is more time-saving and convenient, more sensitive and accurate, easier to control furnace water temperature, less oxidation loss, and more uniform metal composition, resulting in better casting quality!

Automatic Furnace Drying Function: Furnace drying is a relatively complex and lengthy curve heating process. To extend the service life of the medium-frequency furnace lining and reduce production costs, proper furnace construction and drying techniques are crucial. Our innovative automatic furnace drying function allows for pre-setting the required time and temperature for different drying stages based on the drying temperature requirements of different refractory lining materials. Based on the PLC’s preset time and temperature values, it initiates with a single button press, automatically matching and steplessly adjusting the medium-frequency power to control the heating rate and prevent cracks in the furnace lining, thus achieving automatic curve drying. This avoids human error and reduces worker labor time and intensity.

Furnace Breakage Prevention Alarm Function: The unique dual furnace breakdown prevention alarm function employs a combination of differential current and DC injection detection. This provides highly reliable, comprehensive, and rapid protection for the furnace system against furnace leakage and any grounding faults. The detection system has an early warning function; when the furnace lining thins to a certain extent, it will sound an alarm to remind the user that the furnace lining’s lifespan is nearing its end, thus preventing furnace breakdown and ensuring safe production. This solves the problem of customers using the furnace until it cannot be started again, with material remaining in the furnace and melting unable to continue.

Furnace Weighing Function: A weighing system can be installed in the furnace body according to customer needs, transmitting the molten iron weight data to the operating platform PLC and displaying it on a touchscreen. This provides a convenient and intuitive view of the current weight of the molten iron in the furnace, facilitating composition adjustments and production scheduling for operators. Simultaneously, the system can achieve automatic smelting. Based on the formula of each grade of feedstock, it can automatically control the weighing and distribution of furnace feedstock, with automatic error compensation, automatic alarm for exceeding tolerances, and printing and recording of feedstock data. The feedstock distribution is highly accurate and fast; accurate feedstock distribution ensures stable molten iron composition, providing a strong guarantee for the production of high-quality molten iron.
