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.
