Quality of strip is mainly characterized by mechanical property, dimensional tolerance, and surface appearance.Uniform mechanical property, desired tolerance, and high surface finish are essential to produce high end products. In caseof mechanical property, while much of this can be achieved through sophisticated process control and good operationalpractice, needless to say that a good quality slab is an imperative for this. Thus, cleanliness, and internal soundness of slabs are some of the prerequisites. Danieli’s philosophy of Quality Strip Production involves through-process control and optimization of casting and rolling processes. The automation solutions for casting process such as Liquid Pool Control System, Dynamic Secondary Cooling, and Dynamic Soft Reduction provide slab with internal soundness, which is free from internal defect, segregation and give favourable grain structure through improved solidification. On the other hand, rolling solution such as Coil Quality Estimation ensures desired mechanical property and its uniformity over entire length of a strip in real-time processing in the rolling mill. An intergrated solution, therefore, is the key. Furthermore, Danieli is planning to integrate automation solutions for bulging control and Inclusion Control to present the inclusion map of the slab. Thus, the integration and control of automation solutions for casting and rolling provide the key for future products of superior quality.
