Wednesday, October 25, 2017: 4:20 PM
A213-215 (Greater Columbus Convention Center)
Mr. Thomas Bako , Gefran, Inc, Winchester, MA
The purpose of this presentation is to outline challenges faced by the Heat Treat Industry related to momentary short circuits when electrical furnaces are used in the production process. The common causes of the problem will be outlined along with some examples of the types of equipment and processes that are impacted by these phenomena. The heat control loop, focusing specifically the power control and semiconductor protection will be analyzed and discussed. Newly developed technologies to overcome these issues and the benefits of such technologies will also be discussed. Some common causes of SCR Power control failures and technologies related to integrated thermal protection and diagnostics, and how these technologies are in line with Industry 4.0 will also be presented.
