Heat Treating 4.0

Bringing Mature Technology into the 21st Century

by Randy Stott, Managing Editor, March/April 2017, Gear Technology

Companies in our industry have been utilizing heat treating for a very long time, and while technology continues to improve, as well as our knowledge of the many processes, many people still view this as pretty unpredictable.

In fact, sending your perfectly to-spec parts you’ve slaved over for hours to be heat treated is something that might make you cringe…

General manager for ECM USA talks about the advances and latest technology. Over the last two years “in-line” heat treating has been the trend. This process allows for bringing smaller loads to customers on an in-line basis, supplying completely heat treated gears, with low pressure carburizing, higher temperatures, and less processing time.

Another trend that has gained interest more recently is quenching in salt. This is a method that has been used in the past and still maintains its dirty, old-school image, but newer processing makes this a viable alternative, especially for gears, providing single-phase quench benefits similar to gas but less expensive, more environmentally friendly than oil, with superior heat transfer, and 99% recovery.

Do No Destructive Testing

by Jack McGuinn, Sr. Editor, Jan/Feb 2013, Gear Technology

The main safety practice in the big gear industry is “if it ain’t test, don’t use it.” Israel Vasquez, an independent quality systems and NDT level 3 consultant, compares the application of NDT on large gears materials, parts and components to examination procedures practiced by today’s medical practitioners (to not harm the patient). Vasquez says “the basic principles behind NDT are to examine materials, components and/or parts for characteristics (that are) detrimental to their use (i.e., defects), by methods that will not induce physical (and costly) changes (damage) to the item being inspected.”

Because bigger gears have bigger manufacturing costs, non-destructive testing makes perfect sense. After all, these outsized gears are often built to order, requiring only a few pieces, sometimes just one. The amount of testing required is based on economic risk factors. Parts used in critical applications, such as aerospace, aircraft, bridges and nuclear facilities require reliability. Testing required may include any or all of the following:

  • Testing at Raw Material Source
  • Testing of Manufacturing Process
  • Initial Inspections during Installation
  • Periodic Inspections (for service-induced defects)

NDT testing uses computer and digital radiography, magnetic particles inspection and ultrasonic inspection (UT). Selection and degree of testing is often negotiated during the contract arrangements. Typically, these gears need to pass inspections for hardness, burns, cracks, inclusions, porosity and discontinuity.

Gear Grinding gets Integrated at IMTS

by Matthew Jaster, September 10-15, 2012, Gear Technology

More than 100,000 visitors arrived at IMTS in Chicago from September 10–15, making it the strongest showing for the manufacturing technology trade show in over a decade. While many attendees and customers were looking for expert partners, some were acutely aware that they needed gear grinding capabilities that would improve grinding times without sacrificing gear quality. This meant customers were seeking Advanced Solutions.

Customers were also looking for technologically cutting edge solutions at a competitive price and process flexibility. Overall, the following features, capabilities and concepts were discussed during IMTS:

  • Faster setup times
  • Higher productivity
  • Maximizing machine utilization
  • Quality
  • Process flexibility
  • Total cost ownership

Worldwide Steel Output Remains Strong

by Ilya Leybovich, October 27, 2011, Thomas Net Industry News

Worldwide Crude Steel Outputs: Aug 2011 – 125 million metric tons, Sept 2011 – 124 million metric tons.

In spite of the September drop in global crude steel production and month-to-month slowdown in several key steel-producing regions last month (September 2011), the forecast remains strong for the global steel sector. Currently, U.S. steelmakers have produced 64.7 million metric tons of crude steel (which is 6.2 percent more than the same period of 2010).
