1. What is the Equivalent Inductance of Furnace?

The equivalent inductance of a furnace represents the total inductance in the induction furnace system, which is crucial for determining the electrical characteristics and efficiency of the furnace operation.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ L = \frac{\pi \times 4\pi \times 10^{-7} \times N_{coil}^2 \times D_{melt}^2}{4 \times H_{melt}} \]

Where:

\( L \) — Equivalent inductance (Henry)
\( \pi \) — Archimedes' constant (approximately 3.14159)
\( N_{coil} \) — Number of coil turns
\( D_{melt} \) — Diameter of melt (meters)
\( H_{melt} \) — Height of melt (meters)

Explanation: This formula calculates the inductance based on the physical dimensions of the furnace coil and melt material.

3. Importance of Inductance Calculation

Details: Accurate inductance calculation is essential for designing efficient induction furnaces, optimizing power transfer, and ensuring proper furnace operation.

4. Using the Calculator

Tips: Enter the number of coil turns, diameter of melt in meters, and height of melt in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is inductance important in induction furnaces?
A: Inductance affects the power factor, efficiency, and resonant frequency of the furnace system, making it crucial for optimal performance.

Q2: What are typical inductance values for induction furnaces?
