    中频炉坩埚的直径和高度怎样规定？ 中频炉从加热效率来考虑，坩埚越细长，效率越高，因为这时的感应线圈的磁力线最密集，热效率最高。感应线圈直径太细太深了会影响加料的速度，也会影响有效熔化容积太小，所以一般直径与高度之比最好为1比1.5左右。 How to specify the diameter and height of the crucible of the induction melting furnace? The induction melting furnace considers the heating efficiency. The longer the crucible, the higher the efficiency, because the magnetic field lines of the induction coil at this time are the densest and the thermal efficiency is the highest. If the diameter of the induction coil is too small and too deep, it will affect the feeding speed and the effective melting volume is too small. Therefore, the ratio of the diameter to the height is generally about 1 to 1.5.
