The continuous casting process is used for the solidification of molten ste
el into semi-finished shapes. Several factors influence the quality of cast
steel, including mould level oscillation and cooling patterns in the secon
dary cooling zone. This article presents a dynamic model that can be used t
o study heat transfer in the continuous casting process. Temperature measur
ements in the secondary cooling zone are infeasible due to the effects of s
cale and steam on the measurement equipment. Two different feedforward cont
rollers are proposed and compared to eliminate the effects of varying casti
ng speed on the strand temperature; thus reducing the defects in the finish
ed product. The first controller is based on typical controllers found in p
ractice and a design methodology is proposed for the design of this control
ler The second controller has dynamic properties and makes full use of the
plant and disturbance transfer functions in its design. It is shown that di
sturbance rejection of the second controller is better than that of the fir
st controller.
