ZRF - Zinc Remelting Furnace

Overview

The ZRF is designed to remelt recycling material and to premelt ingots of zinc diecasting alloys under safe and stable production conditions. The melting furnace is heated with two heating registers / burners and charged with runners and ingots. The filled level of the furnace is controlled and, if required, automatic feeding by means of a conveyor belt / lifting – tipping device can be used. The molten zinc is drawn off from the crucible in a filled level dependent process by a special zinc liquid metal pump and conveyed in a transport furnace; as an alternative a zinc ingot conveyor belt can be used. A continuous melting process can be implemented by this means. - Zinc recycling system for efficient melting - Robust heating technology with constant temperature control - Melt quality is assured throughout the process - Energy efficient melting ZRF 500 - remelting capacity [kg/h] *: 500; usable crucible content [kg]: 450; heating capacity [kW]: 65 ZRF 700 - remelting capacity [kg/h] *: 700; usable crucible content [kg]: 450; heating capacity [kW]: 87 ZRF 850 - remelting capacity [kg/h] *: 850; usable crucible content [kg]: 450; heating capacity [kW]: 100 ZRF 1000 - remelting capacity [kg/h] *: 1000; usable crucible content [kg]: 550; heating capacity [kW]: 126 ZRF 1200 - remelting capacity [kg/h] *: 1200; usable crucible content [kg]: 750; heating capacity [kW]: 142 * Melting capacity: with continuous charging of ingot Remelting recycling material and premelting ingots of zinc diecasting alloys are explicitly supported. Continuous melting processes can be implemented by the ZRF using filled-level dependent metal extraction and by conveying molten zinc with a zinc liquid metal pump to a transport furnace or by using a zinc ingot conveyor belt. The system can use automatic feeding by a conveyor belt or a lifting–tipping device and provides constant temperature control to assure melt quality while operating energy efficiently.
