Cast iron fine chips at Alu block cause problems

Hi all, I have met with the following problem. Our customer, a large automotive producer, now during holiday season, prolonged the exposure of Alu blocks with these chips that are hardly accessible, from 1 shift to 2-3 (during weekend)-it just stays freely on the line. Normally, they are washed away in further steps. But now, these chips get dry and make very uneasily removable crusts, and one can also watch the rust traces of corrosion likely galvanic type where two metals with different potential are in touch, on Al block (engine).

metal chip warming

Hello, We have a issue but we don’t know what can we do. The problem is that the chips are warming we haven’t finding the reason for this issue, the warm is too high that vapors are present, not only is warming the chip is turning darkness. This is the first time that we have a problem as this, we never had hear about a similar situation What can I recommend?

R.O. vs. D.I. vs. Tap Water when mixing MWF

After attending a MWF seminar in 2000, I was convinced that D.I. water was the best type of water for mixing coolant. The shop was in the country, and there were many dissolved minerals not to mention 'hardness' in what came from the well. Today, I work in a shop that is in a city. The municipal water is used 'as-is' in order to mix coolant - A couple of questions: 1) Do different types of coolant (e.g. Water Soluble vs. Synthetic) require different water? 2) As the city looks after chorination, fluoridation, hardness, etc., is there no advantage left for Deionization?
