Abstract
A cooling element for a melting furnace includes at least one cooling pipe for passing through a coolant, and a support element to which the at least one cooling pipe is fastened. At least one cove plate is welded to the at least one cooling pipe. The at least one cooling pipe has at least one bead which extends in the longitudinal direction of the at least one cooling pipe and to which the at least one cover plate is welded.
Claims13
A cooling element for a melting surface, comprising:
- at least one cooling pipe for passage of a coolant, said cooling pipe provided with two oppositely disposed identical beads extending in a longitudinal direction of the cooling pipe and located diametrically at opposite sides of a longitudinal axis of the cooling pipe;
- a plate-shaped support element at which the cooling pipe is fastened via each of two leg ends of the cooling pipe;
- and
- cover plates, each oppositely disposed relative to the cooling pipe,
- wherein each of the cover plates is welded together with one of the oppositely disposed beads of the cooling pipe,
- wherein the cover plates are made from copper or a copper alloy,
- wherein each of the two beads has a cross section with a trapezoidal shape, and each of the beads has two legs which extend tangentially from a cylindrical area of the cooling pipe to an end of the bead which forms an outer surface of the cooling pipe, and
- wherein one of the beads narrows along a first direction extending radially outward from the longitudinal axis and the other of the beads narrows along a second direction extending radially outward from the longitudinal axis, the first direction being opposite to the second direction.

A process for producing a cooling element for a melting furnace, comprising the steps of:
- providing a blank metal bar with beads extending along a longitudinal extension of the metal bar;
- boring lengthwise through the blank metal bar to form a channel for allowing passage of a coolant and to produce a cooling pipe, said cooling pipe provided with two oppositely disposed identical beads extending in a longitudinal direction of the cooling pipe and located diametrically at opposite sides of a longitudinal axis of the cooling pipe;
- providing a plate-shaped support element at which the cooling pipe is fastened via each of two leg ends of the cooling pipe;
- and
- providing cover plates, each oppositely disposed relative to the cooling pipe, wherein each of the cover plates is welded together with one of the oppositely disposed beads of the cooling pipe,
- wherein the cover plates are made from copper or a copper alloy, and
- wherein each of the two beads has a cross section with a trapezoidal shape, and each of the beads has two legs which extend tangentially from a cylindrical area of the cooling pipe to an end of the bead which forms an outer surface of the cooling pipe, and
- wherein one of the beads narrows along a first direction extending radially outward from the longitudinal axis and the other of the beads narrows along a second direction extending radially outward from the longitudinal axis, the first direction being opposite to the second direction.
