The difference in production flexibility between an intermediate frequency induction melting furnace and a power frequency induction melting furnace

The intermediate frequency induction melting furnace has greater flexibility in production arrangements, and greater flexibility in melting operations. The power frequency induction melting furnace requires uninterrupted operation. It is not advisable to empty the molten iron in each furnace, because intermittent work will increase the cold start, which not only increases the melting time and energy consumption, but also must use a start block every time. When the intermediate frequency induction melting furnace is used for a short period of time intermittently, it can be cold-started without using a starting block, and the molten iron can also be emptied from the furnace. It is very convenient to replace the charge, which is conducive to material replacement in a short time and is convenient for production organization This arrangement has created favorable conditions for the production of machinery repair plants in the iron and steel metallurgical industry that mainly undertake the manufacture of some non-standard equipment, and the demand for castings is large, small in batches, and more varieties.
