INVESTIGATION AND ANALYSIS OF THE ENERGY PARAMETERS OF A NEW INDUCTION CRUBICLE FURNACE „INDUGA“ MFT CU 25000 IN COPPER ALLOY FACTORY „SOFIA MED“

Boris Vassov

Тhere is a high consumption of reactive energy in „Sofia Med“ copper alloy factory. This is due to the specifics of the electrical equipment and the technological processes in the industry.

The main task, that have to be solved, is to increase the power factor and to reduce the consumption of reactive energy. For this purpose the main high energy consuming consumers by workshops have been identified. Each of them is subject to individual research.

The following report examines the research of the energy parameters of a newly installed electrical consumer in the foundry of ”Sofia Med” and analyzes its impact on the energy efficiency of the factory. This is an induction crucible furnace ”MFT Cu 25000”, which is used for melting copper and copper alloys. There is a brief deion of the furnace and its parameters. To perform this task have been used a three-phase network power quality analyzer ”Kyoritsu” KEW 6315, a specialized data processing program ”KEW Windows” and ”Excel”. Quantitative and qualitative indicators of voltage and current on the MV side were recorded. The record covers one working cycle - charging, melting and draining. The furnace works continuously, repeating the working cycles. The good thing about this type of furnaces is, that in case of downtime they can be turned off without the risk of freezing of the metal, because it can be drained. This avoids the operation of the power transformer in a mode close to that at idle mode.
