Tower Melting Cum Holding Furnaces
Silcarb manufactures a Tower Melting-Cum-Holding Furnaces which can be directly coupled along with the die casting machine In a Shop floor which runs die casting of different alloys on each of its machines, a central bulk melter is not always the ideal choice. For these types of shop floor designs, Silcarb manufactures a compact melting cum holding furnace which is directly coupled with the pressure die-casting machine or the gravity die-casting cell.
The furnace comes with a skip charger which charges the shop returns and the fresh ingots into the shaft(tower) of the furnace.
The furnace is essentially divided into three zones
- a)the melt shaft
- b)the holding bay
- c)the tap out well
The melt shaft ensures all the waste gases generated is used in order to preheat the cold charge. The slopesect on the refractory bed is designed with silcarb’s vast experience where the charge spends sufficient time in order to preheat before the actual contact with molten metal.
The holding bay is heated either with a burner or an electric system. If it is an electric system silcarb manufactures both a top heated system as well as an immersion heated system. Sufficient liquid metal is held in the holding bay in order to feed accurate metal temperature and designed to have as low a fuel consumption possible without a compromise on metal quality.
A filter is fixed in between the holding bay and tap out well and a lance pipe for continuous degassing is provided at the junction of the holding bay and the tap out well. The tap out well is fitted with a door which is synchronized with the auto ladle movement where necessary.

Tower Melting-Cum-Holding FurnacesAdvantages
- Reverses flow pattern of flue gases ensures higher retention of the flue in the furnace.
- High steam spent by the flue gasses inside the furnace leads to very low fuel consumption and low melt loss.
- Continuous melting rate ensures better productivity than batch type furnaces.
- No blind corners in refractory which allow easy and thorough cleaning of the furnace.
- Metal tapping is possible through the bottom of the holding chamber.
- Additional heat recuperation can be provided as an option.
Applications
- Diecasting Foundries
- Gravity casting foundries
