250kg Medium Frequency Induction Melting Furnace – Reliable, Efficient, and Safe

Looking for a high-performance melting solution? The Hongteng 250kg Medium Frequency Induction Furnace is engineered for durability, safety, and efficiency, ideal for foundries and metal processing plants worldwide.

Robust, Eco-Friendly Furnace Body

• Premium aluminum alloy: No recycled materials; strong, durable, and long-lasting.
• Precision assembly: Coaxial alignment ensures smooth, concentric tilting.
• Safe and green: Asbestos-free, fully compliant with European environmental standards.
• Stainless steel pull rods: High corrosion resistance for longer service life.

Thoughtful Design for Efficiency & Safety

• Furnace Bottom: Anti-expansion material prevents shell damage under high temperatures.
• Cover Plate: Diamond-pattern anti-slip surface for operator safety.
• 
• Furnace Mouth: Aluminum alloy casting lasts longer than traditional refractory bricks and eliminates frequent replacements.

Advanced Insulation

• High-voltage, high-temperature resistant insulation exceeds 5000V, preventing electrical conduction and magnetic leakage.
• Keeps the furnace safe and reliable during continuous operation.

Premium Induction Coil

• Seamless T2 copper (99.98% purity): No welding, no water leaks.
• Dual-layer protection:
  1. High-temperature insulating paint to prevent short-circuit sparks.
  2. 1cm refractory cement coating to protect the yoke from molten metal.
• Safety anti-fall devices included on every coil.

Smart & Durable Control Cabinet

• Heavy-duty steel construction ensures long life.
• SCR system: 17–18 microsecond turn-off time for faster, stable performance.
• 
• Easy installation: Custom high-temperature, tin-plated wires, no welding required.

Internal Components

• Carbon-free rubber hoses last 5–6 years
• Stainless steel water tubes for durability
• Wires and tubes neatly arranged according to automotive standards

Complete Protection System

The furnace protects both equipment and operators with:

• Short-circuit, over-current, and phase-loss protection
• Grid voltage high/low monitoring
• Cooling water temperature, pressure, and flow monitoring
• SCR over-voltage and over-current protection
• Inverter thyristor monitoring (current rise rate, turn-off voltage, and commutation time)
