SMG: Støtek Melting Furnace
Shaft furnace available in several sizes with a melting capacity up to 7 tons/hour.
The tapered shaft design gives optimum melting efficiency and the flat flame burners in the holding section ensures minimal metal oxidation.
Holding section with possibilities for metal alloying, degassing with porous plugs or lance, and treatment with impeller.
The melting speed is equal to the pouring speed. The holding section capacity is 2 - 2,5 times the ratio of the melting speed to ensure the highest possible metal quality Metal take-out through tap cone, tilting or ceramic transfer pumps with launder.
STET – STØTEK Mega Holding Furnace
- Up to 22,5 tons holding capacity
- Electrical heated with energy consumption approx. 50 kW/h (with 22,5 tons volume)
- Developed for keeping maintenance time and cost low
- Easy refilling of the furnace
- Hydraulic tilting for discharge of metal
STE, STI, DTE, DTI – STØTEK HOLDING AND DOSING FURNACES
- Heating with radiant heating in the top or directly in the metal with immersion heating elements.
- Holding furnaces for operation with open ladles.
- Dosing furnaces operated with ceramic dosing units and standard gravity dosing launders. Optional with Pro-Dose launders for dosing up-wards approx. 800 mm compared to standard gravity launder.
- Scissor jack for lifting and tilting.
