Pipe and profile manufacturing
with mineral oil-free cooling lubricants
IN most cases, pipes and profiles made
of steel, galvanised steel, stainless
steel, and lightweight or non-ferrous
alloys are produced with cooling
lubricants mixed with water.
Only pipes and profiles with thin walls
can also be manufactured ‘dry’ or with
minimal amounts of cooling lubricants.
Many different requirements apply for
water-miscible cooling lubricants.
The suitable products must feature
the following characteristics: cooling
and lubrication of the roll material
and the transport and forming rollers;
flushing of the transport rollers and
forming rollers to remove metal
abrasions; corrosion protection
for system parts and workpieces;
high resistance against microbial
contamination; no unpleasant odour
development, especially during the
welding of the ends of the roll; low-
foam solutions or emulsions; and good
demulsifying of third party oils. In the
past, mostly mineral oil-containing
cooling lubricants were utilised during
pipe and profile manufacturing. Today,
mineral oil-free qualities, so-called
fully synthetic cooling lubricants, are
gaining ground.
There are good reasons for that.
A switch from mineral oil-containing
to mineral oil-free products bears
the following advantages: significant
reduction of cooling lubricant
consumption (up to 30 per cent);
excellent third-party oil emulsification;
due to the transparent solution, it is
easy to observe the entire production
process; and residue of the cooling
lubricant is fully water-soluble and can
easily be removed with water-based
industrial cleaning products.
Modern Hakuform cooling lubricants
for the pipe and profile production
of Chemische Werke Kluthe GmbH
do not contain mineral oil or critical
ingredients such as boron derivatives
or formaldehyde materials. Chemische
Werke Kluthe GmbH has more than
40 years of experience with the
development, production, and sale of
fully synthetic cooling lubricants for
forming processes. This extensive
expertise is evident in the current
product qualities.
