Abstract:
1. Continuous casting mold for liquid metals, especially liquid steel, comprising: steel charging plates, which are arranged parallel opposite each other to form the casting cross section and are surrounded by water tanks; cassette-type copper plates, which rest against the steel charging plates and bound the casting cavity; possibly end plates, which are inserted at the end faces of the casting cavity for establishing the thickness and/or width of the cast strand and close the casting cavity at the end faces; and coolant channels that connect an inlet with an outlet in the copper plates at their contact surfaces with the steel charging plates; wherein the thickness ( 10 ) of the copper plates ( 3 ) between the coolant ( 11 ) and the hot side ( 3 a ) of the copper plates ( 3 ) varies over the width (2×L) and/or over the height ( 12 ) of the mold, wherein the coolant channels ( 9 ) run in the copper plate ( 3 ) and at least partially in the adjacent steel charging plate ( 2 ); wherein a cross section ( 14 ) of the coolant channel ( 9 ) is smaller in a meniscus region ( 13 ) than elsewhere in the coolant channel ( 9 ).
