SCOPE OF THE PRESENTATION



BASIC DESCRIPTION OF THE ELEMENTSfurnace - quench tank association

• Direct transfer from the furnace into the quench tank• no heat loss (charge is fully located in the heated zone)• Furnace is immediately available for the next load• many combinations possible



Increase production by adding one furnace

• Many possibility to combine furnaces and quench tanks• Additional elements may be included anytime



I. The furnace loading sequence

full or semi-automatic handling



II. The quenching sequence

fully automatic



III. The bath unloading & furnace reloading sequence

full or semi-automatic

Major advantages for your benefit

The performance due to the concept

• Tailored installation by combining modular elements and processes

• Allows to treat parts of various geometrical form requiring specific processes

• Direct transfer of the load from the furnace into the quench tank(s) without lock chambers

• Incomparable flexibility and polyvalence for your production

• High productivity due the immediate availability of the individual elements



The economical performance

• Reduced production costs (consumables, productivity, high process quality (less wasted parts, post machining, etc.)

• High productivity (immediate availability, rapid change of types ofatmosphere, rapid heat up duration, etc.)

• Strongly reduces maintenance costs

• Technology based on continuous - and simultaneous engineering to meet future requirements




The technical performance

• Functional split of the elements (optimal efficiency, no danger, easypreventive and active maintenance without production drop)

• No high temperature mechanics (each mechanical part is accessible from the outside at room temperature)

• Circular disposal of the heating elements in the furnaces, multi-cascade regulation

• Bell-type furnaces (limited gas and power consumption, rapid change of atmosphere, perfect gas agitation, high CPK/CAM)


• Ultra modern processes and process regulation (EASYTHERM)
