For heat treatment applications, different types of furnace systems exist which are designed according to processes and through-put performance. Beside the knowledge of process technology which has to be used professionally, one needs for the furnace systems which are operating in a temperature range of 900° to 1300°C, high professional know-how in case problems occur, which influence the product respectively production results negatively e.g.:

• non-uniform temperature-distribution
• burner problems ( high wear,metaldusting etc.)
• sensor problems ( measuring error,aging etc.)
• muffle-wear ( cracks,glasing etc.)
• problems with inner transportation-systems ( chains etc.)
• door – sealing problems
• short life-time of circulation-fans
• unsufficient quenching results
• high wear at graphite-insulation and heating elements
• corrosion at furnace-housings
• problems with the heat treatment atmosphere
• problems with control-systems
