What is a high frequency induction furnace

High frequency induction furnace is also called high frequency furnace, it is a kind of induction furnace. High frequency furnace heating mode is through the tube oscillation circuit to produce high-frequency electromagnetic fields, and then added to the sample, the sample to carry on the induction, produce eddy current (eddy current), resulting in a joule heat, melt sample heated up fast, so called high frequency induction vacuum furnace.
High-frequency induction is an advanced way of heating, because only in the sample is high frequency power output during burning, burning, after the completion of high frequency induction is stopped. High frequency furnace after the start, do not need temperature preheating time, may at any time of the sample for analysis.
Has a very excellent combustion performance, high frequency furnace carbon sulfur conversion rate were higher than tube furnace, carbon can think a few of 100%, sulfur according to relevant data, can reach more than 99%.
The prominent advantages of high frequency furnace is adaptable for samples, especially for tubular furnace, electric arc furnace special material is difficult to burn, for example, high chromium stainless steel, high manganese steel, electrothermal alloy, intermediate alloy, pure metal (Ni, Co, Cu, etc.), silicon in the alloy, chromium iron, ore, slag, sinter, oil shale, graphite, tungsten carbide, rare earth materials and various non-metallic materials, etc., all have good burning effect.
