Basic Enterprise Information
Hebei Yuantuo Electromechanical specializes in the R&D and manufacturing of complete sets of induction heating equipment. The company provides full-process delivery capabilities including overall equipment design, self-developed power supply, on-site installation and commissioning, and delivers customized equipment solutions for the metal plate heat treatment industry. Our core flagship equipment includes the Galvanized Plate Online Induction Heating Production Line, which is applicable to renovation and new supporting projects of various continuous galvanizing pipeline conditions.
Overall Equipment Structure and Operation Logic
The whole production line consists of six units: feeding conveyor, induction heating main unit, constant temperature detection, PLC control system, cooling protection and discharging guide. The feeding section is equipped with insulated deviation-correcting rollers to prevent spark damage to zinc coating during thin strip operation. The heating main unit is equipped with self-developed IGBT digital power supply, which heats the plate body directly through electromagnetic eddy current, different from open-flame radiation heating mode. The whole control system realizes linkage adjustment of speed, power and temperature to ensure long-term uninterrupted continuous production. The Galvanized Plate Online Induction Heating Production Line supports 24-hour full-load stable operation to meet mass coil processing demands.
Key Technical Parameters
1.Power supply power ranges from 100kW to 3000kW, with support for parallel capacity expansion of multiple units
2.Applicable plate thickness: 0.15mm–3.5mm; applicable plate width: 500mm–2000mm
3.Controllable heating temperature range: ambient temperature to 750°C, stable constant temperature for standard galvanizing processes
4.Conveying operation speed: 20m/min–200m/min, synchronously matched with original galvanizing processes
5.Electric energy conversion efficiency: 65%–80%, energy consumption reduced by 30% to 50% compared with gas heating
Operational Performance Advantages
1.Stable zinc coating protection effect. Centralized and controllable heat input brings small overall plate temperature difference, greatly reducing defects such as zinc coating peeling, oxidation and zinc spattering, and improving finished product yield.
2.No waiting preheating time for startup and shutdown. Power output cuts off immediately after shutdown with no energy consumption from empty furnace heat preservation, lowering daily power operation costs.
3.High automation level. The whole equipment adopts touch screen PLC centralized control with stored multiple sets of process formulas; parameters can be switched with one click when changing plate specifications. Only one patrol inspector is required for a single production line.
4.High safety and environmental protection level. No combustion waste gas, open flame or flammable and explosive media. The overall equipment operating noise is lower than 75 decibels, and closed water circulation causes no external sewage discharge, complying with industrial environmental inspection standards of all regions.
5.Strong installation adaptability with modular split structure. The equipment can be directly arranged in new workshops, and old galvanizing production lines can complete equipment docking and commissioning in a short cycle without large-scale civil engineering demolition.
Practical Application Fields
The equipment matches multiple working procedures for galvanized plate processing: preheating of galvanized strip steel before entering zinc pot, stress relief annealing of galvanized plates, heating pretreatment before stamping and bending, and low-temperature tempering repair of plates with defective coatings after galvanizing. Customers cover manufacturers producing home appliance outer coils, building enclosure galvanized coils, automotive structural steel plates and ventilation duct plates.
Supporting Manufacturer Services
1.On-site survey of site dimensions in the early stage, free provision of equipment layout drawings and power process calculation schemes
2.72-hour full-load test inspection before equipment delivery, with complete wiring drawings, operation manuals and process documents attached
3.Professional engineers conduct on-site complete machine installation, wiring and full-line commissioning, and deliver practical operation training for factory operators simultaneously
4.Customized non-standard solutions available; coil structure, power output parameters and control programs adjusted for plates with special thickness or material
Company environment
Comparison with Traditional Gas Heating Equipment
1.Smaller floor space. The equipment volume is only one-third of gas furnaces with equivalent output, saving workshop space
2.Less labor input. Gas furnaces require two to three full-time operators, while induction production lines only need routine patrol inspection
3.Low post-operation maintenance cost. No regular replacement of refractory furnace lining or annual inspection fees for gas pipelines, with low replacement cost for wearing parts
4.Short construction period for renovation. Retrofit installation on old production lines can be put into production within three to seven days; gas furnace renovation involves construction of flues and explosion-proof pipelines, with a construction period more than twice longer
