Selection method of induction melting furnace capacity

To determine the capacity of an የማዋጣትና የማቃጠያ ምድጃ, it is necessary to comprehensively consider the melting rate or overheating capacity, the weight of a single casting, and the economics of investment.

The molten metal required for a single casting can be considered to be provided by a single electric furnace, or it can be provided by considering multiple electric furnaces operating at the same time. When the molten metal requires a large amount and is used continuously, multiple electric furnaces are usually used to operate at the same time. This liquid supply method is more flexible and reliable, and the equipment is extremely stable. However, compared with a single large tonnage equipment, it covers an area of ​​up to , The investment cost is high. When the demand for molten metal is not large, or when the liquid is supplied intermittently, a single electric furnace is more appropriate.

The higher the melting rate of the electric furnace, the higher the production efficiency. To increase the melting rate, the input power of the power supply must be increased, and the power is directly proportional to the electromagnetic stirring force. Therefore, if the power is too large, it will cause the molten metal to stir vigorously, accelerate the wear of the furnace lining, and affect the life of the furnace lining and the quality of the metal. The power frequency electric furnace is designed according to 1.5-2.5H/furnace, and the induction melting furnace is designed according to 1-1.5H/furnace.
