Abstract
A method and a device for casting a strand from molten metal is presented. The molten metal is poured into a mold and then pulled out of the mold as a strand having a liquid core characterized by a solidified shell and a tapering liquid pool. The pouring level associated with the rate at which the liquid metal is poured into the mold is regulated by determining the pouring level and influencing the inflow of liquid metal into the mold by means of a controller whose control parameters are adapted on-line, by means of fuzzy techniques, to any change in the parameters of the controlled system corresponding to the pouring apparatus and the mold.
