HIGH-PERFORMANCE QUENCHING OILS WITH VERY FAST QUENCHING SPEED

DURIXOL high-performance quenching oils distinguish themselves by their very fast quenching speed. They are used primarily for quenching in continuous lines and shaft furnaces with open quenching systems and for quenching in immersion baths after flame and induction heating.

The superior product stability ensures particularly high process reliability. The quenching oils require minimum monitoring and bath care, yet boast virtually unlimited service life. 

High evaporation resistance, low viscosity, low specific consumption and particularly good cleaning properties ensure unsurpassed economy even at difficult applications.

HIGH-PERFORMANCE QUENCHING OILS WITH FAST QUENCHING SPEED

Characteristic for our DURIXOL high-performance quenching oils with fast quenching speed is their intensive and at the same time particularly low-stress and low-distortion quenching behaviour. The oils are therefore suited for a wide range of applications in terms of materials, components and heat treatment and offer top flexibility of use in a diversity of heat treatment processes in multi-purpose chamber furnaces, shaft furnaces, pusher type furnaces or fixture hardening systems. 

The superior product stability ensures particularly high process reliability. The oils require minimum monitoring and bath care, yet boast virtually unlimited service life. 

The extraordinary high evaporation resistance of the oils with simultaneously low viscosity will allow very good flow also through optimised batches. Low specific consumption and good cleaning ability are also advantageous in terms of surface quality and overall process costs.

MULTI-RANGE QUENCHING OILS WITH LOW-DISTORTION QUENCHING PERFORMANCE

The most important feature of the DURIXOL and SYNABOL multi-range quenching oils with low-distortion quenching performance is their increased, yet also particularly low stress, quenching characteristic. The oils are therefore particularly suited for quenching of high alloy steel and high complexity components sensitive to distortion and cracking. Particularly consistent and low-distortion hardening results are achievable.

The special product concept of the multi-range quenching oils also allows adjustments to the quenching characteristics by increasing the oil bath temperature. 

The superior product stability ensures particularly high process reliability. The oils require minimum monitoring and bath care even at high application temperatures, yet boast virtually unlimited service life. 

Exceptionally high evaporation resistance allows particularly consistent cooling over the entire cross section of a batch. Increased stability of dimension and form will in addition contribute to the lowering of process costs

MARQUENCHING OILS

DURIXOL marquenching oils offer extraordinary low distortion after quenching. They are thus used for quenching of components of varying sizes and geometries that are particularly sensitive to distortion and cracking. 

They are also used for tempering as well as sealing cup oil.

The oils have a very high evaporation resistance and a very high flash point. A particular advantage, apart from the extraordinary low-stress quenching, is the superior thermal stability and minimal need for monitoring and bath care.

VACUUM QUENCHING OILS

DURIXOL vacuum quenching oils offer controlled quenching characteristics and are also easily degassed. The oils have only a low tendency to absorb moisture and are creating particularly bright component surfaces. 

The oils are designed especially for use in vacuum furnaces with integrated oil baths. They supplement the high pressure gas quenching process where steel quality and component geometry demand higher quenching performance. 

The oils show a very low oil vapour formation and have a high evaporation resistance. The unsurpassed thermal stability with simultaneously low need for monitoring and bath care is a particular advantage, apart from the intensive and at the same time low-distortion quenching performance.
