Furnace system for copper industry

ANDRITZ provides conversion, melting and refining furnaces for primary and secondary production, as well as for the copper processing industry .ANDRITZ Maerz supplies turnkey furnace systems for copper and metallurgical metallurgy precious.

Directly to the wire

Direct-To-Wire is a filter technology that optimizes the production of "highly refined copper coils" (FRHC coils) for the production of copper scrap rods. Copper FRHC liquid can be used directly in the process of casting and rolling steel wire. This technology is based on the long experience of ANDRITZ metal in furnace construction and, due to its versatility, can be installed in existing or new copper rod plants. Depending on the required production capacity, Direct-To-Wire can be made with three different furnace concepts.

ANDRITZ METALS concept furnace with Direct-To-Wire technology 240 to 600 t / d: efficient furnace for melting combined with two drum type furnaces for filtration and casting

40 to 300 t / d: Flexible tilt furnace for melting, refining and casting, can be expanded by second furnace, 20 to 30 t / d: Blast furnace for melting, refining and casting, expansion By second furnace for minimum investment. To achieve optimum performance and cycle time, all ANDRITZ METALS furnaces are equipped with high-pressure and high-pressure hoses in addition to other technical advantages.

Furnaces and ovens

or the effective melting of the various copper qualities, ANDRITZ Maerz provides furnace shafts and heaters. The heater enables the melting of copper cathodes, anode residues, and high-grade copper scrap with very high energy efficiency. High efficiency is achieved thanks to the one-burner control system and optimal furnace geometry. The material is charged to the shaft with a bypass hoist. The burner is mounted around the lower shaft, providing the molten energy. Emissions move upward through the shaft to pre-heat solid waste at the top of the shaft. Copper liquids can be brought to the next step by means of a cooker or washing machine.

The furnace is equipped with an additional fireplace to keep, reduce, and handle additional copper. Therefore, low quality scrap can also be used. The molten copper is passed through a washing machine to refine the furnace. Production capacity up to 90 t / h can be achieved.

Rotating switch

MAERZ TBRC is a specialized instrument for the production of brass and precious metals. A central feature of the Top Turning Transformer (TBRC) is its high melting and refining efficiency. Typical input materials include different quality copper alloys, alloys containing precious metals from lead production, and anode lubricants from copper electrolysis. Depending on the task, various water-cooled types are used to melt, oxidize and reduce.

High performance is achieved through variable rotation speed of the vessel combined with the use of oxygen technology. By rotating in the melting process, the hot lining continuously underneath the material is cooled, resulting in optimum heating performance. In addition, the refining process is accelerated by continuous mixing of liquid baths. For castings or reductions, the entire conversion vessel can be tilted to cast into a washing machine or truck. Capacity ranges from 5 to 50 tons and even more can be achieved using different designs.
