Oil Application

05/30/2007 6:32 AM

Please can anyone help me,Advice on oils I am an Electrical Technician at a coil processing company where we take 30 ton coils and cut them into plates for our customers,On the one line we have to apply an oil film over the cut plates which the customer insists be Castrol Rustilo DWX30 however we currently use a spray process that uses compressed air in a vessel and forces the oil through the nozzles and atomises the oil to form a fine mist,However due to the mist spray the machine operator cannot work due to the fumes/spray as it becomes hard to breath.

  • Is the another oil one can use that is thin enough to be sprayed on to the plates and not causes the fumes when atomised?
  • besides spending alot of money and building an extraction unit is there another way of getting a fine layer of oil onto the steel plates.

we only apply the oil on the top of the plate then it is stacked in bundles one ontop of the other where the untreated side then sits ontop of the treated side.

Have you tried contacting the oil company? They will have a number of handling suggestions.

Re: fumes and atomisation - if you atomise you're going to get fumes - that's the way it works - fumes are made up of vapour and tiny (<20nm) condensed droplets.

An alternative approach would be to protect your operator - whether with an NBC-type suit or in a separate room.

In Eurpoe, we would not be allowed to have such a process "in the open". The spraying would have to be done in a sealed chamber, without personnel access, and there would have to extraction with condensing and collecting of the oil vapour, which would have to be a) recycled round the system and/or b) disposed of correctly i.e. not vented to atmosphere.

As a minimum - get your operator into a suit with its own air supply.

Same rules here, however, some companies are either ignorant of the law or too cheap to protect the workers from a known carciogen such as oil.

I bet the workers have not even read the MSDS sheets for the chemicals they are working with.

Hi grryvg

I do not know where you are.....the mist spry system does not work...if you lift the lower plates you will see that the oil has formed small circles and at places there is just none the mass pushes it out.IS the product you cut into plates mild steel for pressing plants..there is a machine that has been used for many a year that does just what you are asking...one type is german and the second from the usa...ask Ian currin on 0825554989 to assist and I am sure he will.

best

I've been thinking - what you need are a set of rollers - "foam" covered - foam is oil soaked - plate gets coated both sides as it passes through. Such a machine could easily be added to the end of your process line. Life of foam dependent on material chosen - perhaps felt would be better.

There is an application called vapour Phase Corrosion Inhibitors. These VCIs come in many forms and can be applied to sheets and even enclosed spaces. Check the Google search with vapour phase corrosion Inhibitor and you will get excellent suppliers of VCIs for your application. The application is simple and designed to last under salt spray corrosion also.

application called vapour Phase Corrosion Inhibitors. These VCIs come in many

These are "Volitile Corrosion Inhibitors" and are impregnated in to plastic sheets, paper and bars. They would not be applied to the steel sheets directly. However, there are a multitude of chemical rust ihibitors out there like the Castrol product. They are rarley put on full strengh. You don't have to atomize the spray for effective application. Reducing the nozzle pressure may help.

Have you looked into the possibility of using an electrostatic oiler?
