Optical Coil Protection (OCP)

Increased safety through early detection of wear and crucible damage

OCP

OCP is a patented system for measuring local temperature distributions on the inner face of coils installed in coreless induction furnaces. It reliably identifies wear and crucible damage such as erosions, cracks and metal tongues as well as elevated yoke temperatures. This system also provides reliable monitoring of the sintering process in addition to normal melting and holding operations. OCP can be installed in most any coreless induction furnace.

 

Benefits:

Increased safety for people and equipment
Safety is improved by early detection of crucible damage and prevention of coil damage and breakthroughs
of molten metal.

Improved process reliability
Our OCP is the only system to offer full-scale temperature monitoring already during the sintering
process. Presence of moisture does not affect the measurements. Full functionality is ensured even for
the melting of zinc alloys and galvanized scrap.

Increased equipment availability
Visualisation of the temperature in front of the induction coil helps detect local crucible wear, thus facilitating
repairs of local defects and the scheduling of relines.

Low investment and operating costs
The OCP sensor cable is embedded in the permanent lining, eliminating additional costs when replacing the
crucible. This results in significantly reduced maintenance costs overall, compared to other crucible
monitoring systems.
