HotEye^TM

Technology that sees hot objects

OG Technologies, Inc. (OGT) has invented HotEye^TM, a breakthrough technology in non-contact sensing¹. HotEye^TM is a proprietary imager, designed for high temperature applications. This technology can capture the image of an object that is as hot as 1,450°C (tested, equivalent to 2,640°F) with the same image quality as if the object were at room temperature. This innovation is based on OGT's expertise in optics, CCD technology, and electronic signal processing. HotEye^TM can be used in imaging systems for dimensional measurement and surface defect detection at up to 1,450°C.

To date, the technology has been applied to two distinct applications:

(a) HotEye™ RSB Systems

The HotEye™ Rolled Steel Bar Systems are designed for both the bar and rod mills to address the ever-lasting surface defect problems. Successful tests and verifications have been documented in detecting both transverse and longitudinal defects, such as seams, checking marks, tears, slivers, overfills, and so forth. Details can be found in the HotEye™ RSB Brochure (PDF format) and the 2004 AIST Technical Conference Paper (PDF format).

Integrating a HotEye™ RSB system into a rolling mill is simple. HotEye™ RSB comes in as two modules. The sensor module is to be installed in line, with the bar path centerline aligned. The computing module is to be installed on the mill floor. A cable bundle will be supplied to link the two modules. The HotEye™ RSB is linked to the rolling mill through one relay signal connection and one TCP/IP connection, in addition to all other required utilities. HotEye™ data will be available to any offices and pulpits that have PCs linked to the mill network. The connections is illustrated in the schematic of the Installation Layout (PDF format).

Products installed in North America and Asia.

(b) HotEye™ BECS

The HotEye™ Bar End Control System is designed to address the bar end issues associated with the Hot Shearing of a Hatebur hot forming presses. Details can be found in the BECS brochure (PDF format). The system

• Measures each cut-off length as the steel bars are sheared (+/-0.005");
• Detects and tracks bar end positions (+/-0.125" at shear);
• Monitor the shear knife and the first station for any residual slivers or bar ends; and
• Is calibration free.

OGT is current working on expanding the monitoring capability into the 2nd, 3rd and 4th forming stations for correct material transfer and proper alignment.
