Abstract

Presented as part of the International Journal of Engineering Science and Technology (IJEST)01 January 2013,Two of the major problems in continuous casting are cracks and breakouts. Usually primary cracks are associated with breakouts and can also develop into more pronounced cracking in the secondary cooling zone. This paper aims at designing a fuzzy control system to control the dynamism associated with the continuous casting process in order to eliminate cracks and breakouts. The fuzzy control system, (which is a multi-input, multi-output system), obtains inputs of temperature related values from the thermocouples attached to the mould wall. The major outputs of the controller are casting speed and cooling rate and these are controlled with the aid of variable speed drives. The fuzzy controller attempts to eliminate primary and secondary cracks that could be linked to high casting temperatures by varying the secondary cooling rates. The controller is simulated using MatLab to observe its response to various inputs.,International Journal of Engineering Science and Technology (IJEST)
