Tower Melting Furnace
Continuous shaft melter with holding bath for die casting and foundry lines
Overview
What it is and where it works
A shaft (tower) furnace where ingots and bulky returns are charged at the top and preheated by the flue gas on their way down to the melting zone, with an integrated holding bath at pouring temperature. A dross and iron inserts trap is included to avoid alloy contamination. It is used in die casting and gravity foundries that need a steady supply of liquid metal over several shifts.
Melt rate 300 to 7,000 kg/h Sized to your plant: tell us your target output.
- Holding bath
- 500 kg to 20,000 kg; sized at 1 to 2 times the melt rate in kg/h
- Energy use
- 580 to 900 kWh/t measured in independent studies
- Charge preheat
- Flue gas preheats the charge in the shaft before it melts
In your plant
Where It Is Used
- Central melting for high-pressure die casting cells
- Gravity and low-pressure foundries with steady demand
- Remelting in-house returns (runners, gates, rejected parts)
- Feeding transfer ladles to holding furnaces at the machines

Frequently Asked Questions
How big should the holding bath be?
A common rule of thumb is a holding bath in kg of at least one to two times the melt rate in kg/h. Below about 150 kg/h tapping rate, two-chamber units lose efficiency.
Can I charge chips or light scrap?
Shaft furnaces are designed for ingots and bulky returns. Chips and light gauge scrap are better handled in a sidewell or vortex furnace or a rotary furnace.
