For the steelmaker involved in the hot rolling of steel slabs or billets, knowledge of steel temperature is vitally important. Accurate measurement of the steel temperature can be invaluable in determining the final metallurgical properties and quality of the metal.
The Land fibre-optic system (available from Protea Automation Systems) can be located at different positions under the mill roller table, view the target between the rolls and provide continuous accurate measurement without being in physical contact with the scale-free metal surface.
This rugged system is easy to install and designed for trouble-free operation. A low-cost sighting tube/purge unit houses a readily demountable, modular fibre-optic probe. The associated electronic amplifier unit, located remotely, is linked by a sealed fibreoptic light guide. An airline, connected to the sighting tube, is provided to purge a sight path for the thermometer and is the only service regularly required by the thermometer optic head. No water-cooling is required and no special tools are required for removing the probe.
The electronics unit is provided with electrical power from the associated Systems 4 Landmark Graphic signal processor which provides electronic signal treatment of the thermometer output allowing averaging, peak picking or sample and hold outputs and temperature display. An optional serial communications facility gives digital RS232C or RS422A outputs and allows access for system parameter adjustments from a remote computer.
The picture (inset) shows the land 'Fibroptic' system for understrip temperature measurement in steel rolling mills.
