SS Weaving Lubricant

Vineet,

A product very very successfull for a more difficult fine wire drawing is Drawmet 44. Almost all the copper wire drawing machine in India use this product. There have been a number of instances of Drawmet 44 being used for fine steel wire drawing as well. On the other hand Drawmet 22 has been widely and very successfull used for all types of Aluminium wire drawing.

Castrol S4 (posssibly Syntillo No 4 which is a nitride based product and is highly prone to rusting). The nitride composition would not allow it to be used in any western country today.

Dear Adeni

Thnks for the suggestions . But as application is not of SS wire drawing it is of weaving of ss fine wire ( SS Screans or net).

Will Drawmet 44 work in this application

Vineet,

There are two ways of looking at the problem, one to bench mark against and best results and second benchmark against worst conditions or results.

Copper is a "difficult-to-draw" metal, as it is ductile and in fine guage wire drawing prone to breakages. Thus die-lubricant for copper or cuprous alloys is heavily fortified with fats.In most cases the die-lubricant consists of an emulsion, where the concentrations can be as high as 20 to 25% Oil (fats ) to give ideal results. It is here that Drawmet 44 "consistently" scores over other known products in India.

For the wire drawing of low guage SS or Tungsten neat oils( in fact ISI VG 460 or 680 Cylinder oils) or even plain engine oil have been successfully used.

In your case i.e. Steel fine guage wire drawing, Drawmet 44 with 2 to 5% concentrations should suffice. The main requirement is heat removal from die ( hence water based product.) The secondary requirement, is a litte concentartion of oil, for lubricity and post wire drawing, a bit of rust protection.
