Proximity Switches hese robust sensors are designed for the difficult conditions of the steel industry. The High Temperature Inductive Proximity Switches IH can work in ambient temperatures up to 180 °C. The MHM Magnetic Proximity Switches detect a variation of the magnetic field and are used in conjunction with a magnet. They are used for position control of mechanics in high ambient temperature. Laser Distance Measuring Sensors he Trilas TL series and Dilas FT series are digital, high resolution, non-contact laser distance meter sensors. The target may be hot (up to 1300 °C) or cold, stationary...

Continuous Caster Slab Caster • Detection with scanning HMD Rota-Sonde DC. • Slab width measurement with Laser Triangulation sensors Trilas TL. • Dummy bar detection with Laser Barriers V5 or Optical Barrier VFT1. • Detection on cooling bed with VFT1 without reflector. In order to deliver the right products to the hot rolling mills, it is important to measure the dimensions of slabs, billets or bloom produced in the continuous caster. DELTA has designed special laser sensors able to make non-contact measurement with high accuracy on hot products and to withstand the difficult environment of the...

Bloom / Billet Caster • Detection with scanning HMD Rota-Sonde DC. • Bloom / Billet length measurement on the cooling bed with two Dilas FT sensors. • Detection with VFT1 without reflector. Run-Out Table • Slab dimensions measurements (width length – thickness) on the run-out table just before the marking machine with laser triangulation sensors Trilas TL, time of flight Laser Sensor Dilas FT and Laser Barrier V5 or Optical Barrier VFT1. • Control of the slab pile level with high power Optical Barrier V

e Bloom / Billet Reheat Furnac Length measurement • Length measurement with two Laser Sensors Dilas FT. • Dimensions calculation with Dilas FT and MXP processing unit. The charging operation is critical. It is important before moving the billet or bloom into the furnace to know the length and the position of the head and tail in order to avoid any damage. On the discharging side, it is also important to detect the product and to know its position and eventually the skew.

Charging • The Detection is made using Optical Barrier VFT1 or Dilas FT. • Laser sensors Dilas FT are used for positioning and in combination with a Laser Barrier V5 or Optical Barrier VFT1 for length measurement. Discharging • Detection of bloom / billet inside reheat furnace with high power Laser Barrier VLP21/VRH. • Measurement of the position and skew of the billet / bloom with Laser Sensors Dilas FT420

Long Product Rolling Mill Bar/Wire • Speed measurement with Velas DL velocimeter Bar / Wire • Tracking of hot product with scanning HMD Rota-Sonde DC. • Cropping control with high accuracy scanning HMD Rota-Sonde DC. • Detection of a bar with the scanning HMD Rota-Sonde DC or Stato-Sonde Z50/Z56/Iris Z6500. Hot Metal Detectors (HMD) are designed for tracking hot products at the different stages of the hot rolling process. In critical operation such as for the control of the shear (head/tail crop, or cut to length) it is important to rely on accurate sensors which will detect in less than 1 ms...

Horizontal loop Vertical loop • Horizontal loop measurement with the Infrared Loop Scanner Rota-Sonde TS. • Vertical loop measurement with the Infrared Loop Scanner Rota-Sonde TS.

Long Product Rolling Mill Length measurement • On the fly length measurement with Laser Sensor Trilas TL and Laser Barrier V5 or Optical Barrier VFT1. Tube • On the fly length measurement The Velas DL measures the speed of product and, by integration in the time, measures the length. For more accuracy, Laser Barrier V5 detects head and tail. Tube • Detection of the exact position of head/tail with Rota-Sonde DC4500-F equiped with special Flame Filter. The optimization of hot rolling processes requires the use of accurate and reliable sensors for detection and measurement. DELTA has developed...
