The blast furnaces of ILVA Steel Works in Taranto require 11 tons of high-quality sinter each year. To satisfy these demands, the two sinter plants (400 sq meter of suction area each) must operate with high productivity and efficiency. In recent years, many activities have been undertaken by ILVA and CSM to achieve and maintain the sinter productivity and quality required, and to reduce the sinter costs. Application of an appropriate technique in the blend formation practice, consistent with the characteristics of the employed materials, has allowed optimal quality sinter level. An organizational technique, that concerns daily maintenance, emergency repair service and better planning of maintenance activities derived from the inspections has improved the efficiency (95% in 1993). Sinter mixture characteristics, which determine the rise of permeability, use of hydrated lime, interventions on operating conditions such as higher sinter layer, improvements of control process have resulted in a productivity level of 40 tonnes/sq meter/24 hr productivity. All these actions and the modifications of the ignition furnace have resulted in a reduction in energy consumption from 1,450 to 1,300 MJ/tonne of sinter. Sinter cost reduction has been reached by this lower energy consumption together with optimal use of hydrated lime quantity and heat recovery from the sinter cooling plant.
