For the production of flat products, liquid steel is generally cast in form of slabs in continuous slab casting machines. These slabs are inspected, scarfed and then reheated in slab reheating furnace to the rolling temperatures before being rolled to hot rolled coils in a semi continuous or continuous hot strip mill. Development of thin slab casting and rolling (TSCR) is a step forward to reduce the number of process steps in the production of hot rolled coils (HRC). Originally TSCR technology was developed with the primary goal of reducing the production and investment costs but today it has become one of the most promising production routes to maintain steel as a leading material in technological application and it is being considered as the technology which has reached a high degree of maturity. Casting speed of 6.0 m/min for slab thickness of 50/55 mm is quite common. Initially, only commercial quality plain carbon steels were being cast through thin slab caster route. But presently most of the steel grades including low, medium & high carbon, HSLA line pipe grades and steel grades for automotive application including IF grades can be cast through thin slab caster route. In fact this technology has brought paradigm shift in steel technology of casting and rolling. The thin slab casting and rolling technology was made possible because of the following improvements in casting and rolling processes.
