INNOVATIVE BILLET WEIGHING SOLUTIONS
BLH Nobel’s billet weighing solutions supports conveyor weighing as well as installations that require the billets to be lifted for weighing. The main concerns in steel production are high temperatures, harsh environment and how to synchronize lifting of the billet in order to perform the weight measurement in a fast, secure, and stable manner. Our extensive experience in the metal industry allows us to understand your specific needs and to be your partner offering full on-site installation, commissioning and technical support.
The BLH Nobel billet weighing solution is a fully integrated system with a documented yield increase that gives the customer an improved return-on-investment (ROI). Our high accuracy billet weighing system supports conveyor weighing applications and installations that require the billets to be lifted for weighing.
Unique KIS Load Cell:
The KIS load cell is capable to withstand dynamic forces, high lateral forces, shear stress and bending effect. Its smart features make it resistant to high overload forces no matter the direction. This unique construction makes the scale stronger, more accurate and globally less expensive than the standard U shape one. Thanks to the smart design of our KIS 1 load cells, complicated mechanical arrangements such as rods are avoided in the coil weighing system. BLH Nobel can provide OIML applications with KIS 11 load cell and our unique G5 PM with OIML R76 approval
CASE STUDY FOR BILLET WEIGHING
The Challenge:
BLH’s customer is one of the world’s leading steel producers. Their goal was to improve the billet cutting process in the continuous billet caster by controlling the billet weight and improving production supervision. The billets vary in cross-section size from 120 mm2 to 140 mm2, and in length from 9 m to 11 m. Target weight ranges from 1.1 to 1.6 tons. The main concerns were the high temperatures involved, and the need to synchronize lifting of the billet in order to perform the weight measurement in a fast, secure, and stable manner. The customer had considered several alternatives but did not find a system suiting their needs.
The Solution:
BLH Nobel proposed a solution in which the billets would be weighed in the ripper area. The operating temperature is lower in the ripper area, so the BLH Nobel solution required fewer components—resulting in easier installation, lower maintenance requirements and a more cost-efficient investment. The equipment, supplied by BLH Nobel, included a mechanical block with cylinders and load cells, and the G4 instrument for weight display and communication to the customer’s PLC system and operations room. This system offered high accuracy and excellent control of production.
