HotEye®Technology
that sees hot objects OG Technologies, Inc. (OGT)
has invented HotEye® a breakthrough technology in non-contact sensing1. HotEye® 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® 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 applications in the hot rolled long product mills as HotEye®
RSB Systems.
The HotEye® Rolled Steel Bar (RSB) Systems are designed for both the bar and rod mills to address the
ever-lasting surface defect problems. The applications are now extended into
the rail/shape mills and seamless tube mills. 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. Capability of automatic detection, classification, marking on the images, repeating pitch calculation, and alarming for roll marks (repeating defects) is also well documented. Details can be found in our publications with AIST first in 2004 and also in 2018 (Iron & Steel Technology, Aug 2018), both available upon request. Benefits have been reported with reduced internal rejects and improved customer satisfaction, resulting in quick return on investment. Integrating a HotEye® RSB
system into a rolling mill is simple. HotEye® comes in as three 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. A cooling module is equipped
to ensure the system operation in harsh mill environment. 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.
Products installed in North
