RAUCH Magnesium dosing furnaces MDO are the answer to the steadily increasing energy prices for electricity. This gas-fired furnace generation achieves up to 30% energy cost savings compared to conventional burners by using preheated combustion air.

The operating cost savings can be up to 80 %, depending on the costs for electrical energy.

As a result:

• Cost-efficient heating.
• Uniform heat distribution to the crucible.
• Exhaust energy is directly used.
• Good controllability through electrical heating of the pumpchamber.
• High life-time of the components.
• Spare- and wear part compatibility to the standard MDO.

Design:

• Design as a two-chamber furnace with melt- and pump chamber.
• Electrically heated pump chamber.
• Melt chamber heated with recuperator burners.

Advantages:

• Constant melt level as well as a stable temperature in the pump chamber, resulting in constant casting conditions.
• Design as an upward or downward pump system.
• Shot weights in a range from 0,2 kg to 30 kg and even more.
• Depending on design, dosing accuracy of ± 0,75 %.

RAUCH Ingot prewarming and feeding units MVE fulfill the procedural and safety relevant requirement of drying and prewarming of the feed material and a steady and gentle automatical feeding of the smelter plant.

Through the continuous feeding, a steady melt temperature and a constant melt level will be guaranteed.

RAUCH Ingot prewarming and feeding units MVE characterize themselves by:

• Optimized prewarming process of different ingot sizes.
• Warming of the ingots to a save core temperature.
• Optimized automatically feeding of the melting furnace in dependence of the melt level.
• Space saving design.
• Installation size from 150 up to 1500 kg/h.
• Electrical heated or with a heat exchange device, which is heated by the exhausted gas of a gas fired melting furnace.

Expendability:

• Ingot extension magazine (MVEE) for the stocking up to 25 ingots.
• Variable assembly through slewable roller conveyor.
• Movable MVE.

The use of the RAUCH Magnesium liquid metal transport systems MFT in a Magnesium die casting foundry or in a Magnesium recycling facility accord the implementation of a trend-setting energy and rationalization concept and opens essential economic advantages.

Use of the RAUCH MFT:

• The melt will be pumped from the melting furnace (MSO) into the electrical heated Magnesium transport container (MSB).
• The Magnesium transport container will be carried with a forklift to the Magnesium dosing container (MDB).
• The dosing container at the die casting machine, used as by the liquid metal transport concept, just needs the holding power.

The main advantages of this concept are:

• Meltback of class 1 return material, up to 40%.
• Low space requirements at the die casting machine.
• Constant melt level in the dosing furnace.
• Low utility service at the die casting machine.
• Constant melt temperature in the dosing furnace.
• Central melting of the whole material quantity in one smelting plant.
• Batch-wise melt quality control possible.

The RAUCH Magnesium melting furnace MSO is a gas fired or electrical heated one chamber melting furnace.

Special characteristics of this furnace technology are:

• Demand-oriented furnace size with a melting capacity of 650 up to 1200 kg/h.
• Modular organization through more melting furnaces by higher melting requirement.
• Fast and steady thermal transfer by using a high-velocity burner.
• Safe furnace handling by using protective gas in 3 separate atmospheres.
• Optimized homogeneity of the melt by using a stirring device or a jet pump.
• Easy transfer of the Magnesium melt in a therefor designed transport container (MSB) via a RPM-regulated dosing pump.
• Feeding of the melting furnace ingot prewarming and feeding unit (MVE) or by manually/automatically insertion of return material.

The RAUCH Magnesium melt container MSB is used to transport or for holding liquid Magnesium alloys.

The RAUCH MSB was developed for the following tasks:

• Riskless and safe transport of the liquid Magnesium with a forklift or a crane.
• Carriage of liquid Magnesium to the casting furnace.
• Steady feeding by an integrated pump.
• Low temperature fluctuation by optimized heat output.

The RAUCH Magnesium dosing container MDB is a stationary dosing furnace, constantly fed with liquid Magnesium to ensure uniform quality.

Basic requirement for this system is a central smeltery.

RAUCH MDB offer:

• Holding and docking places for up to two melt containers.
• High dosing capacity by low dosing time up to 5 kg/sec.
• Fully automatic and steady feeding of the dosing container.
