Medium Frequency Metal Induction Heating Furnace for Steel Bars

Overview of Medium Frequency Metal Induction Heating Furnace for Steel Bars

Thyristor is a solid-state semiconductor device composed of four layers of alternating P- and N-type materials. It functions as a bistable switch, conducting current only when triggered by a gate signal, and remains conducting until the voltage across it drops below a certain threshold. Thyristors are widely used for controlling high-power electrical circuits, offering efficient and reliable performance in various industrial and electronic applications.

Features of Medium Frequency Metal Induction Heating Furnace for Steel Bars

• High current and voltage handling capabilities
• Low on-state voltage drop, reducing power loss

Specifications of Medium Frequency Metal Induction Heating Furnace for Steel Bars

Here are the specs for a medium frequency metal induction heating furnace designed for steel bars. This furnace heats steel bars fast and efficiently. It uses electromagnetic induction. The steel bar gets hot quickly inside the coil. It saves power compared to older methods.

The power input runs on standard 3-phase AC. Common voltages are 380V or 415V. The power frequency is medium, typically 1 kHz to 10 kHz. This frequency works well for heating steel bars. Power ratings vary. Models range from 100 kW up to 1500 kW. Choose based on your required output and bar size.

The furnace handles different steel bar diameters. It works for bars from 15mm up to 100mm thick. Heating capacity depends on power and diameter. Expect speeds from 500 kg per hour to over 5 tons per hour. Heating temperature is adjustable. It reaches 1200°C easily. Temperature control is precise, within +/- 10°C. Uniform heating prevents scale loss.

The main unit includes the power cabinet and heating station. The induction coil is water-cooled copper. Cooling water flow is critical. Minimum flow is 10 liters per minute per 100 kW. Water pressure needs at least 0.2 MPa. The water must be clean and soft. The furnace structure is heavy-duty steel. It withstands industrial conditions. Overall dimensions depend on the power level. A typical 500 kW unit might be 3m long, 1.5m wide, and 2m high. Weight is substantial, often several tons.

Operation uses a PLC control system. The interface is simple. Operators set temperature and time easily. Safety features are built-in. Overheat protection shuts things down automatically. Leak detection stops the furnace if water flow fails. Over-current and over-voltage protection guard the electronics. Emergency stop buttons are clearly marked. The furnace meets CE safety standards. Electrical components have IP54 rating for dust and water resistance. Regular maintenance keeps it running smoothly long-term.

Applications of Medium Frequency Metal Induction Heating Furnace for Steel Bars

Medium frequency metal induction heating furnaces work well for steel bars. They heat bars fast and evenly using electromagnetic energy. This method offers many benefits over traditional heating. Factories use these furnaces for several important jobs.

Heating steel bars before forging is a common application. The furnace brings bars to the right temperature quickly. This makes the metal soft enough for shaping. It saves time and energy compared to old gas or coal furnaces. The temperature control is very precise. Workers avoid overheating the steel. This prevents damage and waste.

Annealing steel bars is another key use. The furnace heats the metal to a specific point. Then it cools down slowly. This process softens the steel. It makes the bars easier to machine or bend later. Annealing also reduces internal stress in the metal. This improves the bar’s final quality.

Hardening and tempering steel bars also uses these furnaces. First, the furnace heats the bar very hot. Workers then quench it fast in oil or water. This makes the surface extremely hard. Next, the bar goes back into the furnace for tempering. Tempering uses a lower heat. It reduces brittleness caused by hardening. It balances hardness with toughness. This gives the steel bar the right strength for its job.

Stress relieving is important too. Steel bars can develop internal stress after forming or welding. The induction furnace heats them to a medium temperature. This relaxes the metal structure. It removes those harmful stresses. The bars become more stable and less likely to crack later.

Straightening bent steel bars is a final application. Heating specific spots makes the metal expand. When it cools, it contracts. This controlled heating and cooling pulls the bar straight. It’s efficient for fixing bends without damaging the steel.

5 FAQs of Medium Frequency Metal Induction Heating Furnace for Steel Bars

What does this furnace do?
It heats steel bars quickly using electricity. A magnetic field creates heat inside the metal itself. This is efficient. The steel gets hot fast for forging or heat treatment.

Why is medium frequency good?
Medium frequency penetrates steel well. It heats the bar evenly through its cross-section. Low frequencies heat too deep. High frequencies only heat the surface. Medium frequency is right for bars.

How does it heat steel bars?
The steel bar passes through a water-cooled copper coil. Electric current flows in the coil. This creates a strong magnetic field. The field induces currents inside the steel bar. These currents generate heat throughout the bar.

What bar sizes can it handle?
It handles many diameters. Common sizes are 20mm to 150mm. Larger diameters need more power. The furnace power rating determines the maximum size it heats effectively. Tell us your bar size.

Does it need special maintenance?
Basic maintenance is key. Regularly check the cooling water system. Keep the coil clean. Inspect electrical connections for tightness. Replace worn insulation. This keeps it running reliably. Maintenance is straightforward.
