How should you maintain induction coils used in hardening applications? Elbow grease — a little goes a long way. After each use, a simple solution of soap and hot water will remove sticky quench and debris. Scrub hardened dirt with a Scotch-Brite pad. Check for pitting, arcing, and insulator damage. If all is good, use a hot water rinse, and it’s ready for use. If the inductor is to remain on the machine for an extended period, it is advised to wash it and the associated bus daily. Check for damage. Following this simple procedure will reduce business waste.

2. Maintaining Tooling Fixtures for Induction Hardening

Tooling fixtures are usually maintained simply by storing them inside a mandrel and a box. This system will prevent coils from getting distorted.

Most tooling should be rinsed in hot water to wash off the polymer and then dried and stored away for future use.

It is a good practice to use deionized water for cooling the power supplies.

3. Switch to Aqueous

As industry tries to become more “green,” a number of companies are switching from lubricants that are petroleum or mineral oil-based to water-based (“aqueous”) lubricants instead. However, some of these companies then make the mistake of not changing their degreasing fluids that they use to remove these lubricants prior to their next processing operations, and stay with their standard degreasing fluids, such as acetone or alcohol, which are not effective at fully removing water-based lubricants. Instead, they need to run tests to find an appropriate alkaline-based degreasing fluid for such water-based lubricants, since alkaline-based degreasers will be effective at removing such lubricants. Commonly available dish-detergents (alkaline-based) have been shown to be highly effective for such use.

Heat Treat Today’s Meet the Consultants: Daniel Kay

Heat Treat Today recently unveiled its Heat Treat Consultants page in the October 2018 print edition (available in digital format here) and at FNA in Indianapolis, Indiana. We offer this comprehensive listing of heat treat industry consultants as part of our efforts to help minimize the effects of heat treat “brain drain.” With so many heat treat brains growing older, the expertise that once used to reside inside of manufacturing operations is dwindling. Where, then, do manufacturers with in-house heat treat departments go when they need heat treat answers?

Turn to Heat Treat Today and our comprehensive list of heat treat industry consultants, which we will introduce to you one by one in this occasional feature, “Meet the Consultants”. There is no more comprehensive list of heat treat consultants. Learn more about Dan Kay of Kay and Associates, and then click through to the page to read more details about each consultant. We are adding more regularly. Contact them directly, or call us and we’ll introduce you to them. Whether it’s a technical process question, a safety concern, a compliance issue, or a business related question, one of our heat treat consultants will be able to help. If you are a consultant and would like to be listed, please contact Doug Glenn.
