Technology has played a major role in nearly all aspects of achieving higher quality and greater efficiency in heat-treating processes. These and other factors help drive customer demands for higher quality and faster delivery. The challenge for many heat treaters is meeting such demands while justifying the cost of implementing the technology that makes it possible. Many heat treaters use incremental improvements to existing technology to yield positive results. In this context, incremental improvements are steps to automation. The first step may be automated recipe controls retrofitted into an existing control cabinet. A typical next step would be a plant-wide Supervisory Control and Data Acquisition (SCADA) system providing widely enhanced visibility to what is happening on the shop floor.
Better technology allows for greater trust in the heat-treating process. In addition, it gives the heat treater the opportunity to free up resources for different tasks.
Data acquisition, the logging of process-related data for later analysis, has been around for a very long time. Historically, it existed with paper chart recorders and has evolved into electronic, computerized formats providing information to all areas of the business. It is almost impossible to read an article related to data acquisition (or to information technology in general) and not see the term big data. This term implies the fact that we are gathering more information than ever before. The challenge, naturally, becomes putting that information to good use.
What makes data “usable” is specific to each operation, and each operation is different. Business drivers in heat treating tend to be initiated from quality control, where electronic information requirements provide proof of traceability or of meeting industry requirements such as CQI-9 and AMS 2750. We find that quality is the biggest driver for investments in data-acquisition technology, but the benefits should not stop there. Every part of the business – operations, quality, sales and maintenance – can benefit from a data-acquisition strategy. Information can be gathered from all areas of a business and evaluated holistically to make better decisions on current operations.
Preventive-maintenance programs are common to all heat-treating operations, and all of them are well-intentioned. In our experience, a large percentage of maintenance is reactive. When maintenance is reactive, unplanned downtime takes place with a significant impact on production planning as well as the possible load impact of rework or scrap parts. Preventive maintenance is planned, with planned activities and planned downtime that allow the maintenance department to work around production schedules. Data-acquisition and control technology both provide additional parameters (for example, the operating time of an element, pump or burner or the number of times a door has been opened and closed) useful for ensuring that maintenance is less reactive and more preventive.

It is better to be prepared for an emergency and never have to use it, than to have an emergency happen and not be prepared. For this reason, preparing your combustion equipment for electrical outages is very important. In this article by Jason Safarz from CEC Combustion Safety he reviews 10 tips that will help…
The installation of electric duct heaters can take one of two forms – flanged or slip-in mounting. If you are trying to compare and contrast slip-in vs flanged the following article will give you the basics. Existing Ducts For retrofits into existing ducts, flanged mounting like that available on the INDEECO QUZ model is usually preferred. With…
The use of specialty, industrial circulation heaters has grown dramatically in the past two decades. Most notably, circulation heaters are used in the petrochemical industry for refining crude into gasoline and other byproducts, the nuclear power industry for precise control of coolant and other fluids as well as in the chemical industry for effectively cleaning…
The AHR Expo is the World’s largest HVACR market. Over 2,ooo companies and 40,000 visitors will come together this January 26-28, at the McCormick Place in Chicago, Illinois. There will be over 100 educational seminars, workshops (presented by ASHRAE and others), and new product presentations. This show is a great opportunity to stay current with the…
Safety is of paramount importance in the petrochemical industry not only for the employees at the plant or refinery, but also for the end-user. Otherwise, a dangerous situation at a refinery could cause it to be shut down at a moment’s notice and cost significant amounts of time, effort and money to rectify. This single…
It can be frustrating to hear a reference to something and not understand what they are talking about. For this reason we want to explain what Delta T is in relation to the heating industry. While no one expects you to remember the Greek alphabet in its entirety, unless you were educated in Greece of…
This article gives great advice on when shutting down for regular scheduled maintenance. Follow the five P’s of maintenance shutdown for a smooth and easy going experience. Routine maintenance shutdowns of thermal fluid systems involve a staged process before, during and after the operation to reduce the amount of idle time incurred in the plant….
