Pipe and profile manufacturing with mineral oil-free cooling lubricants

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

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.
