the unit power consumption of an induction melting furnace ?
the unit power consumption of an induction melting furnace ?
індукційна плавильна піч refers to the total electric energy and metal consumption of the induction melting furnace in the process of heating, melting and (or) heating the scrap metal charge from room temperature to its rated temperature in a unit time (1 hour). The ratio of charge weight in kilowatt-hours per ton (kWh/t).
1. The induction melting furnace includes electric furnace melting equipment and its auxiliary equipment. The auxiliary equipment for casting and melting of the induction melting furnace includes its own supporting hydraulic and electrical transmission system for furnace body tilting, furnace cover opening and closing, water cooling system, control and measurement system, etc. The determination of its unit power consumption should be consistent with the induction melting furnace . The measurement of the unit power consumption of the main circuit of the furnace is carried out at the same time. Therefore, the total power consumption of the induction melting furnace also includes the sum of the unit power consumption of the main circuit of the induction melting furnace and the unit power consumption of the auxiliary equipment.
2. The unit power consumption measurement of the induction melting furnace shall comply with the national standards of GB/T 10067.3-2015 and GB/T 10066.3-2014.
3 Коли індукційна плавильна піч is casting and smelting, the unit power consumption of different smelting temperatures is as follows:

Remarks: With * means including the power loss of the induction melting furnace transformer (that is, the cumulative power consumption of the main circuit input is measured at the primary side of the transformer), without * means not including the power loss of the induction melting furnace transformer (that is, the accumulated power consumption of the main circuit input is at transformer secondary side metering). |
