LaCam® - EAF laser profile measuring unit for non-contact measurements of refractory linings in metallurgical reaction and transport vessels.
LaCam®- EAF refractory lining measuring system (electric arc furnace)
New laser profile measuring system based on a laser scanner of the new generation.
The LaCam® profile measuring system has been developed for non-contact measurement of refractory linings in metallurgical reaction and transport vessels. LaCam®- EAF refractory lining measuring system (EAF installation) is a model of the LaCam® series profile measuring systems. This new system generation is designed for installation at Electric Arc Furnaces.
The graphical user-interface permits detailed investigations of the wear development as well as automatically printed reports of the measurements.
The LaCam®-EAF refractory lining measuring system (EAF installation), including laser measuring head and the appropriate coupled electronic units, is stationary-installed at the EAF and can be remoted from the control room. Connection to a control and measuring unit as well as to an optional workstation is realized by a local computer net.
If measurement is necessary, start and monitoring of results will be made at the operator desk (console and monitor). After automatic scanning of the surface, the results are available within a few seconds on all PCs connected to the net.
The LaCam®- EAF refractory lining measuring system (EAF installation) determines:
- Residual brick thickness of the refractory lining.
- Brick development of the refractory lining.
- Rate of wear of the different refractory materials.
- Volume of EAF.
- Deformation of EAF shells.
Furthermore, the LaCam®- EAF refractory lining measuring system (EAF installation) enables:
- maximizing EAF life time.
- control of gunning material consumption.
- specific application of gunning material.
- area dependent optimization of lining material quality.
- trend analysis and forecast of the durability of EAF lining.

2. Control and operator unit
The control and operator unit reads-in the measuring data of the laser measuring head and controls it. The distance between control and measurement unit and laser measuring head is – depending on local situation – up to 10 m. For each laser measurement system, one control and measuring unit is designated. A measurement can be made directly at this unit or via remote control from a workstation at the control room. Furthermore, all measurement results are represented and can be evaluated. A modem for remote service is included.
