REPORTEDLY UNUSED MELTING PLANT FOR PRODUCING COPPER ALLOYS TOTAl CAPACITY UP TO 120 000 TONS PER YEAR. CONSISTING OF: A. Power-supply system; B. Melting stock collecting and loading units; C. Induction smelting furnace (6 units) each capacity up to 20,000 tons/year; D. Waste gases exhaust and cleaning systems; E. Casting and piling mechanisms; F. Horizontal continuous casting machine. The units are designed to smelt scrap for production: Ingots 55 000.00 tons per year Castings 45 000.00 tons per year Equipment may also be used for other purposes that stipulate the processing of scrap of both non-ferrous and stainless steel and pig iron. DETAILS: A. Power supply system (110 kV and 6.3kV/380V) The power supply system includes: High-voltage power-supply system, 110 kV; Transformer 16 MW (110kV/6.3kV); Average-voltage distribution plant (6.3 kV); Transformers (6.3 kV/380 V); Low-voltage distribution plant; Emergency powers supply systems. B. Melting stock collecting and loading units The melting stock collecting and loading complex consists of: 6 loading transportation trays for loading melting stock in 6 induction smelting furnaces; 2 lifting and tilting mechanisms; 5 fork-lift 6-tons trucks; 5 transfer and casting ladle with 3 gas burners. C. Smelting machine The smelting machine includes the following equipment: 6 high frequency induction crucible furnaces, ITMK5 type /6.5 tons 6 frequency converters, electric power 1,850 kW, frequency 150 Hz 6 furnace transformers 6 condenser batteries 6 furnace weigher process control system, small sized closed cycle water cooling system slag removal device removal of crucible lining device D. Waste gases exhaust and cleaning system The system includes: drawing-off hoods pipe-lines fans supplied with sound-proofing devices filters for cleaning waste gas The main locations of drawing-off devices: 6 induction crucible furnaces casting areas in front of smelting furnaces transportation trays for molten metal to continuous casting devices hot-air ovens in front of continuous casting devices casting stations in front of 2 lines with ingot molds The drawing-off device that uses cooling air has the capacity of 240 000 m3/h. To eliminate components of gases HCI and HF, special lime is injected in dry filters. Drawing-off fans are supplied with sound-proofing devices. E Equipment for casting and piling ingots The complex of the equipment includes: 2 casting machines (for ingots), each of them having 2 casting platforms supplied with automatic weighing devices 1 ingot piling device. F Horizontal continuous (or semi-continuous) casting machine The continuous casting machine was intended for manufacture of cylindrical copper alloy castings. The machine proper consists of the continuous casting unit (castings of 150mm, 185mm and 250mm in diameter) and channel-type induction furnace. Besides, the supplied equipment includes several ingot molds for three strand casting, and circular saw for cold cutting.
