Tower Melting Furnaces

Silcarb manufactures Tower Melting Furnaces with capacities from 500 kg to 10,000 kg and a throughput of up to 3,000 kg/hour. Designed for efficiency and simplicity, these shaft furnaces use industry-best castable and backup linings. Charging is done via skip chargers (top-loading) or push-charging systems (end-loading), with burners positioned at the bottom for optimal fuel efficiency. Heat transfer occurs through direct impingement and convection, ensuring effective melting. Some models incorporate a grate system for gradual heating, improving thermal efficiency.

Silcarb offers both stationary and tiltable tower furnaces. Stationary furnaces feature automated pneumatic tap-out systems for minimal turbulence and dross-free metal extraction. Tiltable furnaces use high-capacity hydraulic cylinders with dampers and high-temperature seals for safe metal tapping. With a 50% fresh ingot and 50% shop floor return charge ratio, these furnaces achieve a fuel efficiency of 500 kWh/ton of aluminium melted.
