In the beginning of rolling mill time there were no load cells. Mill setup was entrusted to the skills of experienced operators who made careful manual adjustments on a slab to slab or strip to strip basis. When strain gages, and then extensometers, and finally load cells became available, they were used to monitor roll force at first only for ...
