by the factory is around $0.5m, which is relatively high for a factory in a developing country. As mentioned above, the automatic control system and measures used to control the process of melting iron and steel scrap, was analyzed and reviewed in order to evaluate its effect on the mechanical and electrical maintenance of the factory.
The process of steelmaking has undergone many changes because of technological and economical reasons. Large, integrated steel mills were built in the 1950s and 1960s at high capital costs and limited flexibility. They produced steel in batches by refining iron ore in several steps. Increasing energy costs made thermal efficiency in steel mills a
