The series and parallel master control board technologies used are all domestically leading control technologies, developed internally by our company, with independent intellectual property rights, and are not sold externally.
To ensure equipment quality and operational stability, all key electrical components use well-known domestic and international brands.
All equipment is equipped with a computer smelting management system, which collects equipment operation data and monitors alarms in real time.
Using independently developed computer-aided design software and simulation systems to ensure the power supply and furnace achieve optimal matching.
The copper bars and copper pipes inside the power supply use well-known domestic brands. The copper bars are sandblasted and passivated, and are manufactured according to standards. The components in the power supply are arranged reasonably, the wiring and cabling are standard, and maintenance is convenient.
Closed-type capacitor cabinet design, wide output copper bars, low loss, and more optimized cabinet layout.
Designed with fuses for quick blowing, providing effective protection for the medium-frequency power supply and transformer.
The technical parameters of all equipment shall not be less than 1.3 times the rated power to improve the reliability of the equipment.
Gap-free Rotation Technology: The furnace rotates without gaps during tilting, effectively preventing molten iron from entering the furnace and ensuring safe equipment operation.
Structure of the furnace side panel: The furnace side panel structure adopts the one-piece steel plate molding technology, ensuring robustness and durability.
Fall-proof guard: The furnace is equipped with a fall-proof protection device. During furnace tilting, the fall-proof guard automatically rises to form a protective barrier, preventing personnel from falling and ensuring safer operation.
Goose-tail unwatered magnetic yoke: Designed with 0.23mm-thick high-permeability oriented silicon steel sheets produced by Baosteel and Wuhan Iron and Steel. The silicon steel sheets on both sides of the yoke gradually recede backward by 15mm, forming a goose-tail shape, effectively preventing magnetic field diffusion at the yoke edges from causing stainless steel baffles to heat up and expand. The yoke's arc-shaped cross-section seamlessly adheres to the inner and outer walls, covering 85% of the area, increasing effective magnetic permeability while also providing better support for the coil.
Dual Leakage Furnace Alarm System: Utilizing both DC injection and AC induction dual alarm systems, it detects furnace lining thickness based on leakage current magnitude. When metal penetrates or approaches the induction coil, the alarm device is activated in advance to cut off power, effectively preventing furnace penetration incidents.
The induction coil of the medium frequency furnace is wound on a dedicated mold using oxygen-free copper tubes made of Luoyang Copper, with no joints in the middle. The ends are welded by pure copper argon arc welding, and the copper tubes are made of high-quality cold-rolled copper tubes with TU1 (99.97%) material. There are no weld seams inside each set of induction coils.
Stainless steel water-cooled rings are installed at the upper and lower parts of the induction coil in the medium-frequency furnace, integrated and wound with the induction coil to ensure uniform axial heating of the furnace lining material and extend its service life. Faraday short-circuit rings are also installed at the upper and lower parts of the induction coil to fully absorb the leakage magnetic flux at both ends and prevent overheating of the furnace cross-section. The wiring uses side lead wires to reduce the torque generated by the large-section water-cooled cables during furnace tilting.
The induction coil undergoes 7-11 layers of insulation treatment, ensuring enhanced safety and reliability.
