Secured automatic strand starting on CCM with stopper: application on bloom and slab casters
A specific method for the automatic starting of strands fed through stopper flow control is presented. The methodology includes on one hand the estimation of the flow rate in function of the stopper opening, and on the other hand the qualification of the stopper flow control system prior to strand starting. Moreover, metallurgy and behaviour of different steel grades are considered in order to optimize the mould filling time. Results are given from the installation of the system on one slab caster which produces a wide range of steel grades, and on one bloom caster which produces stainless steel.
