Continuous caster / slab width measurement
This measuring system consists of two triangulation lasers of the ODS-Series and one PC. Data from the laser systems are transmitted via a RS 422 interface to the PC. Every 10 milliseconds the width is measured. The data needed for slab positioning is linked within the PC. After the complete cycling of slabs through the width measurement all results are transmitted to the supervisory process control system via Profibus or Ethernet interface. Slab data is stored for 30 days so that a subsequent analysis can be made at any time.
Billet Positioning inside the furnace
The Laser Distance Meter measures, through the buffer on the run-in roller table, off the billet front surface. As high measuring rate ensures real time positioning in the furnace. By using a second Laser behind the supply table, measuring at the foot of the billet is possible. This way also double-row filling of short billets into the furnace is accommodated. The Laser is protected by appropriate cooling housing against heat damage from the furnace.
Monitoring of material on the roller table for automatic positioning
The measuring system detects passing slabs on a cold roller table after width measurement. The system tracks the slabs on the roller table until they are pushed into a furnace. The laser scanners (in protective housings) are mounted beside at the roller table. The system extends down a roller table of any length. The devices send the measured values via an Ethernet Interface to the measuring PC.
Slab measurement and storage control from the magnet crane
The measuring system consists of two laser scanners attached to the crane cart. The laser scanners measure across beam and along the slab(s) which hang off the magnet. The pick up and setting down position of the slabs is determined (in co-operation with the warehouse-system) and also the widths and number of slabs recorded. A safe collection of single slabs is possible. The data from the laser scanners is processed by an Embedded PC and passed on by Ethernet to the supervisory stock control management system.
Slab position measuring
With this measuring system slabs can be precisely positioned before being pushed into furnace. The laser system comprises 3 devices scanning devices along a centerline 140 mm above the roller table. When the slabs move or lie in the scan line, the position is measured from the head and lengthways. The raw data from the Laser Scanner (distances and angle) are transferred to the measuring PC. The PC evaluates the measurements and the compressed information for the slab head and slab feed-position will be create. With this Information the supervised roller table control can place the slabs precisely.
Slab Width Measurement
This slab width-measuring system consists of two laser measuring systems which are mounted on both sides of the roller table. The measuring systems measure on the long edges of the slabs. By knowing the distance of both systems to each other and the measured data the slab width can be calculated. The evaluation takes place either in a PC or a SPS. At evaluation it should be noted that the slabs can diagonally pass through whilst being measured and can have different forms.
