StrikoMelter® MH-II Aluminum Melting Furnace

Highly efficient shaft melting and holding furnace for aluminum casting

This aluminum melting furnace delivers when your objective is an easy-to-maintain, reliable, durable melting furnace with minimal loss of metal and the highest melt quality. StrikoMelter has a patented ETAmax stack melting design making it the best choice for your foundry production. The StrikoMelter offers foundries of all sizes unparalleled opportunities for a particularly economical production worldwide. The long lasting StrikoMelter delivers more power, complete metal processing, extremely economical energy consumption through integrated waste heat recovery.

ETAmax Shaft Design

The fundamental design philosophy on the StrikoMelter aluminum melting furnace is the ETAmax System. Unlike any other stack melter on the market, this special shaft geometry of the StrikoMelter and its specially designed burner technology combine preheating and melting in the melting bridge. Following the rapid melting of feed material at the lower area, the outlet flow of the waste gas preheats cold material in the overlying shaft area.The countercurrent flow of molten material and gas permits a very effective use of waste heat recovery down to 300° C according to the principle of regeneration. No add-ons are required. Due to this process, fuel consumption and metal loss are significantly lower than for any known competitive product.

Ready Metal

Regardless of the melting process, liquid metal with homogeneous alloy composition, constant tapping temperature at a high degree of quality and purity is available at any time for your production. In most cases, downstream treatment is not required. The molten metal is transferred turbulence-free and without scratching into the metal bath and is available at the exact metal temperature chosen for the casting process.

Lowest Energy Cost

The StrikoMelter with EtaMax – waste gas recovery is the class leader in terms of energy efficiency. Only 2118 ft3/t (60 m3/t) of natural gas is needed to produce one ton of ready for casting aluminum, for example from 50 % ingot and 50 % returns at 720 °C.*

Days

7,300 days are not uncommon: Due to the sophisticated design and the impressive longevity of all materials and components used, the StrikoMelter achieves top availability rates. Less downtime, fewer repairs. More power, more profit.

High Yield

The biggest cost driver in the manufacture of liquid aluminum is metal loss during melting. Through advantageous burner layout and low furnace temperatures, the StrikoMelter makes up to 99.4 percent of the material used available to the casting process as molten metal. Not only on paper, but measured in actual conditions in the foundry.

Impressive melting capacity.

Up to 7000 kg (15,400 lbs) of raw material per hour can be melted in the largest STRIKOMELTER. The integrated heating of the material being melted significantly accelerates processes. Thanks to the recuperation principle, no other mechanical components are required. Energy that is generated is used immediately. From the largest to our smallest furnace. The well-conceived graduated series of designs offers the right furnace for every need. All the way down to 340 kg/h (770 lbs/h) melting capacity.

Holding

The bicameral principle ensures that up to 20 tons of melt can be kept at a constant heat in the holding area, depending on size of the system. The melt is available in a quality that can generally be used without further treatment in the casting process.
