Flexible process configuration enables variable production
Demand for various steel products is constantly changing. Quick reaction to market forces requires flexible production processes that can be quickly re-configured for a variety of steel products.
The continuous casting line involves high temperatures, control of powerful forces, strong vibration, and heavy shock. Control system components must be able to operate reliably in such an environment to ensure the uninterrupted production of quality steel. From precise ingot mold reconfiguration for casting liquid metal, to the safe and controlled transport of solid slabs and billets, Balluff sensors and systems deliver the high efficiency and dependability demanded by today's market-driven steel industry.
The continuous casting line requires continuous operation of the casting ladle to keep it supplied. Movement of the casting ladle must take place under complete control at all times... the consequences of uncontrolled movement can never be allowed to occur.
To ensure the integrity of position measurement signals, sensor redundancy is key. Balluff's double-or triple-redundant magnetostrictive linear position sensors provide two or three fully independent, redundant control signals from a single device.
Smooth starting of the continuous casting line under various conditions of alloy and temperature calls for controlled movement of the dummy bar at the mold gate. Balluff's photoelectric sensors are available in either discrete detection or continuous positioning variants, with a variety of sensing modes and light sources to suit the particular application conditions.
The Balluff Rapid Replacement Module "RRM" allows you to quickly and easily replace the electronic portion of Balluff's linear position sensors in hydraulic cylinders. Simply removing two screws on the old module, withdraw it from the pressure flange, and install the new module. The hydraulic seal at the sensor port remains untouched, minimizing the risk of leaks and preventing dirt and air from getting into the hydraulics system. Safer for personnel too, with no risk of spilling hot oil onto unprotected skin.
Balluff's photoelectric sensors are ideally suited to detecting the leading and trailing edges of cut-to-length hot or cold slabs while they are being conveyed. In the case of hot slabs, sensors fitted with band-pass filters allow slab detection without the infrared heat radiation disrupting the sensor's operation.
Precise position checking and the continuous adjustment of rotational movements are extremely important on the walking beam. Balluff's inclination sensors offer non-contact angle measurement for precise walking beam control. The sensors operate by measuring the deviation from horizontal, up to 360° (one complete rotation).
