ABSTRACT OF THE DISCLOSURE: With a continuous casting mold, the mold side walls each are formed by a supporting wall and an internal plate fastened thereto and getting into contact with the metal melt. On the side of the internal plate facing the supporting wall parallelly arranged coolant channels are provided, which are designed as slits open towards the supporting wall and whose width is smaller and whose depth is larger, than the width of the ribs located between the slits. In order to render the cooling performance particularly effective, the width of the cooling ribs is smaller than, or equal to, 13 mm and the flow speed of the coolant is adjusted such that the heat transmission coeffi- cient alpha between the internal plate and the coolant is between 20 and 70 kW/m2K, preferably between 25 and 50 kW/m2K, such that the heat flow density for the internal plate is larger than the heat flow density for a smooth internal plate having no ribs.
