Steel Industry Process Control Systems
Pennies saved during daily steel production cycles result in hundreds of thousands of dollars by year-end. Vishay billet weighing, roll force measurement, ladle crane, and tundish weighing systems save more than money; they reduce scrap while extending equipment life and service time. We control all vital mill functions with precision accuracy to give you the best production runs possible.
Billet Weighing Systems
Typical caster torches cut all billets to a given length. Cutting to length, however, results in large variances in actual billet weight. Rolling mills roll by weight rather than length. Overweight billets leave rolling mill customers with extra “scrap” steel, which has to be returned and remelted. Cutting by weight, rather than length, resolves the scrap/remelt problem.
Roll Force Measurement
RFS-3 Roll Force Systems are uniquely designed for retrofitting older mills not equipped with force measuring systems and mills with aging load cell based systems. Extensometer kits weld directly to existing posts so no mill modification is required. Extensometers on both the work and drive sides of the mill enable the user to achieve a balanced force at all times. RFS-3 instrumentation provides vital status/alarm indication and work/drive force output signals.
Ladle Crane Scales
Vishay has extensive application expertise in turning ladle cranes into overhead
scales for both original and retrofit mill installations. Cylindrical load cells
or axel, thereby turning the crane into a scale without major rework.
Tundish Weighing Systems
Vishay tundish weighing systems, designed for continuous casting operation, not only control the level of molten steel, they also monitor the integrity of the molds themselves. High temperature load cells (400F) and multiple A-D converter instrumentation based systems provide excellent precision without reducing the sample rate.
