tundish channel electromagnetic induction heating and refining apparatus both low superheat thermostat casting casting process, but also the use of electromagnetic force pinch effect purification of molten steel casting quality is improved, while new active temperature control mode can effectively reduce large baotou water temperature of 10-15 ℃, energy saving effect is remarkable and reducing consumption of refractories, it is suitable for large-scale promotion of the new low-carbon energy technologies.
heating rate: 1-2 ℃ / min;
temperature accuracy: target temperature±3 ℃;
inclusion removal effect is obvious: in particular the reduction of 25μm or less small inclusions especially effective;
decreased about 10%.
