Method of Reducing Silicon Burning Probability in Medium Frequency Furnace The following describes the method of reducing the probability of silicon burning in the medium frequency furnace. The thyristor is the heart of the medium frequency power supply of medium frequency furnace, its correct use is very important for the operation of equipment. It is normal to damage several thyristors occasionally during the use of medium frequency furnace. If silicon is often burned, it will cause alarm. The working current of the thyristor is several thousand a and the voltage is usually one or two thousand v. good protection of the main control board and good water-cooling conditions are necessary. Overload characteristic of thyristor: the damage of thyristor is called breakdown. Under normal water-cooling conditions, the current overload capacity can reach more than 110%; without voltage overload capacity, that is to say, silicon is definitely damaged under overpressure. Considering the
