SA DELEGATION

PADICON® ( PARALLEL DIFFERENCE POWER CONTROL) (DR. TANNEBERGER GMBH)

• High-energy processes are no longer independent, as before; instead, they are co-ordinated, balancing out peaks and troughs in demand against one another. Power demands undergo less fluctuation. The result: peak performance with no peaks indemand.

REINHARD TWEER GMBH IN BIELEFELDCUTS PEAK DEMAND BY 21 PER CENT

USING PADICON

IMPROVING POWER EFFICIENCY

• “PadiconR gives Reinhard Tweer GmbH a crucial advantage: all the foundry‘s furnaces can be operated simultaneously with no rise in power consumption. Peaks in electricity demand can be controlled precisely and sustainably. This not only guarantees that the workflow is uninterrupted, it also cuts energy costs without lowering production”.

THE VALUE OF MONITORING

• The process also provides a transparent overview of power consumption for every connected unit, at any time. New units can easily be hooked up to the system later.

ALD VACUUM TECHNOLOGIES

VACUUM INDUCTION MELTING FURNACES

• Vacuum induction melting (VIM) is one of the most commonly used processes in secondary metallurgy applied for refining treatment in the liquid state and adjustment of chemical composition and temperature.

• To achieve the increasing quality demands on the• resulting material and at the same time

1. save raw materials such as alloying elements due to higher yield; and2. save energy,

• The application of vacuum in the induction melting process is a must for many specialized materials• The process is suitable for the production of high-

purity metals within an oxygen-free atmosphere• This limits the formation of non-metallic oxide

inclusions.

METALLURGICAL ADVANTAGES

• Melting under oxygen-free atmosphere, this limits formation of non-metallic oxide inclusions and prevents oxydation of reactive elements;• Achievement of very close compositional

tolerances and gas contents;• Removal of undesired trace elements with high

vapour pressures;• Removal of dissolved gases e.g. oxygen,

hydrogen, nitrogen;• Adjustment of precise and homogeneous alloy-

composition and melt temperature.

ADVANTAGES

• For this reason, metallurgical operations, such as dephosphorization and desulphurization, are limited.

• The removal of harmful volatile trace elements, such as antimony, tellurium, selenium, and bismuth in vacuum induction furnaces is of considerable practical importance.

• Fast change of program for different types of steels and alloys;

• Precise temperature control;• Low level of environmental pollution from dust

output;

THE VIM-VMC-FURNACE IS A TWO- CHAMBER
