Lubricant replaces soap for steel tube
drawing
For severe reduction in the cold drawing of steel, tube makers generally use phosphate soap, but a polymer-based lubricant avoids phosphate chemicals disposal and energy consumption.
John Neale has developed a polymer enhanced lubricant for the severe cold drawing reduction of steel for a tube manufacturer in Birmingham, UK Severe cold drawing of steel is often carried out using phosphate soap; this has problems associated with disposal of phosphate chemicals, mess, waste, and energy consumption

Lubricant additives benefit SS tube drawing
Work to significantly enhance the lubrication of highly chlorinated tube drawing lubricants - and deep drawing - has lead to the discovery of additives which offer considerable performance benefits.
Lubricants smooth severe cold metal reductions
A range of lubricants can be applied as a coating for the most severe cold reductions in stainless steel alloy, and titanium and are suitable for the most arduous operations.
The specialist tube drawing customer was moving factory and wanted to remove this wet process and all the associated requirements of space for tanks, heating, extraction, odour, etc.
John Neale designed a product which could offer sufficient lubricity to offer trouble-free, severe reduction, drawing of tubes up to 5m long.
Not only does this sort of lubricant need to give superb extreme pressure lubrication but also give cool running through the dies which is particularly difficult on this length of tube.
Traditional high performance tube lubricants give considerable 'judder' through the dies while extreme temperatures effect die life and tolerances when used in this type of application.
After some optimization Superdraw 30/60 based on advanced polymer technology has been selected.
It gives smooth judder-free drawing and low temperatures through the dies.
The surface finish is excellent.
Superdraw 30/60 gave the performance required at a low manageable viscosity and very cost effectively.
