This article presents a case study that reviews the design of a solution heat-treatment system based on specific customer requirements. What complicated the design, and what was done to solve the problem? Let’s find out.
Many variables affect natural gas combustion, including environmental conditions. Corrective measures and enhanced controls can reduce the impacts of these variables and can provide optimum control continuously, maximizing the efficiency of industrial burners.
Attendance at the October 2013 Nadcap meeting was better than most years, but it still yielded fewer heat treaters than there ought to have been. That said, in this article we’ll take a look at the arrival of new specification AMS 2750 Rev. E and some of the changes.
No other segment of heat treating has seen more changes in
technology than data-acquisition (DAQ) systems. While the investment in a new
data-acquisition system can seem quite high, the benefits and return on the
investment can happen quickly if the use is maximized.
Control-room instrumentation has come a long way from the days of drag pens on paper chart recorders and manually tuning temperature loops with trim pots. Most of these instruments were large and heavy steel-cased units that performed adequately for that time. Actually, some of these instruments may still be in use in some facilities if they have been well taken care of.
For many years, single-spot radiation thermometers (sometimes called pyrometers) have been widely used in the steel industry. They have many advantages compared to contact devices like thermocouples. They can be positioned at a distance to “look” at the process and measure the infrared radiation that is emitted by the target object. In this way, they can operate out of harm’s way. Because they don’t touch the surface, they can accurately measure fast-moving objects like steel strip, whereas a thermocouple would suffer from a frictional effect on the measurement.
