Abstract

The automatic control system of steel-teeming ladle heating-up regime (APCS) is developed under conditions of steel melting shop. The implementation of automatic control system allowed high-temperature heating-up of ladles prior to steel tapping and pouring. As a result, it is possible to increase resistance of monolithic refractory lining and reduce the natural gas charge in average by 130 m3/h or 40 m3/h per ladle heating cycle.
