What is the frequency of supply used in core type induction furnace?
Core type induction furnaces typically operate at high frequencies, typically ranging from 50 Hz to 10 kHz. However, the specific frequency used in a core type induction furnace depends on various factors, including the size and type of the furnace and the materials being heated.
Lower frequency induction furnaces (around 50-60 Hz) are commonly used for larger capacity applications, such as melting or heating of metals in foundries. These furnaces are often referred to as mains frequency or line frequency induction furnaces.
Higher frequency induction furnaces (in the range of a few kHz) are used for smaller capacity applications, such as laboratory or specialized heating processes. These higher frequency furnaces offer advantages like more precise control and enhanced heating efficiency for specific materials.
How to Calculate Specific Resistance using Operating Frequency?
Specific Resistance using Operating Frequency calculator uses Specific Resistance = (Frequency of Induction Furnace*4*pi^2*Thickness of Cylinder^2*Relative Permeability)/10^9 to calculate the Specific Resistance, The Specific Resistance using Operating Frequency formula is a property that characterizes the electrical conductivity of a material. It is defined as the resistance between opposite faces of a unit cube of the material. While resistivity is relevant for conductive materials, dielectric heating predominantly occurs in insulating materials where resistivity is very high. Specific Resistance is denoted by ρ symbol.
