Abstract
An apparatus for continuous upward casting of a metal object comprises a nozzle having an upper part, a cooler surrounding the upper part of the nozzle and defining a cooling chamber for receiving a flow of cooling agent, a separating element dividing the cooling chamber into an inner part and an outer part. A guide structure is formed in the cooler near the bottom of the cooler, for influencing flow of cooling agent and intensifying cooling of the metal object near the bottom of the cooler, whereby a solidification front is formed in the nozzle between molten metal and solid metal near the bottom of the cooler.
