RE: Kerosene replacement



Hi Judy,

I'm not familiar with this operation but can offer some thoughts.  What is
driving the need for replacement?  A water-based lubricant may work, but then
you will face problems with rusting or will have to introduce a corrosion
inhibitor into the mix.  This leaves you with using oil-based lubricants.

The use of Neatsfoot Oil is interesting since it is mainly used in leather
processing.  It is derived from an animal source so it should be
biodegradable and is considered to be relatively non-toxic.  The fatty acids
contained in the oil will oxidize during use, forming soaps.  I'm guessing
that the kerosene is used to thin the oil and to make sure it doesn't become
too thick over time.  Dilution with kerosene may also help in avoiding
biological degradation of the oil that would lead to odors.

If any changes are going to be made, I would look at the kerosene component.
K-1 kerosene is relatively pure but some brands can contain 1% or more
aromatics such as tri-methyl benzene.  Some synthetic kerosenes have been
developed that consist of pure paraffin.  The dye is added to the kerosene
because of tax law.  You can still purchase clear kerosene at a higher price.
The dye is not suppose to interfere with the use of kerosene as a fuel, I
have no info as to the health safety of the dye.  Perhaps others can shed
more light on this issue.

Subject: Kerosene replacement




I have a client that makes horseshoe nails.  They have been in business since
1881 and are the major manufacturers of the product.  The equipment that they
use was manufacturered between 1890-1920.  The facility is very clean and
modern.  They use 1006 and 1008 grade steel, which is fed into the machine,
goes
through a series of roll dies that shapes the metal into the nail, including
the
head.  They use a 75% Dyed K-1 Kerosene, 25% Neatsfoot Oil mixture as a
lubricant.  The lubricant is squirted manually on the roll dies, which are
located down the front of the machines, as needed.

Question:  does anyone have an experience with alternatives to this
lubricant?
They have tried 3 products from Richards Apex, but claim that within a week
the
lubricants get dirty and the material clogs in the machine.   Any suggestions
would be greatly appreciated.
