steel shell intermediate frequency furnace

Product Overview

Description

Introduction

1.Power source adopts a parallel resonant circuit, the control circuit is fully integrated, intermediate frequency power source zero voltage soft start. Convenient operation and maintenance, stable,reliable, low repair cost.

2. Intermediate–frequency power source has many function, including overvoltage, overcurrent, lack-phase, under-voltage, lack of water, cooling water temperature overrun alarm protection ,it’s safe and reliable.

3.Melting fast and high production efficiency when Stable power and stable operation.

4.Three-phase full-bridge rectifier, small hign-order harmonics, without interference on power grid, the transformer does not heat and low loss.

5.When power source works, electric and water is saved. Small volume, light weight, safty, wide used

Heating characteristics

1. Intermediate frequency furnace smelting process is stable, the castings have high mechanical strength

2. Oxidation loss, no oxidation melting, reduction of the melting loss

3. Liquid iron have electromagnetic stirring itself and homogeneous metal components, can smelt any chip and small scrap, reducing cost

4. Reduce environmental pollution

5. High power density, fast melting, start melting conveniently

6. Flexible and convenient operation, selected frequency

7. Low construction costs

8. Superb coil design, high quality thick-walled copper tubes , Rational selection of induction loop interturn distance makes the highest conversion efficiency of induction coil ,resistance minimum,so more energy can be used for melting, heating, high strength, coils are prone to damage due to arc and expansive fo rce.
