Abstract
A cooling plate for use in a blast furnace is described. The cooling plate has a copper body having an inner face containing ribs parallel therebetween, having first extremities and separated by grooves having second extremities. At least one of these grooves containing at least a part of a multilayer protrusion extending between its second extremities and having at least one layer made of a wear resistant material that increases locally the wear resistance of the neighboring ribs.
Claims15
A cooling plate for a blast furnace, said cooling plate comprising a copper body having an inner face having a plurality of parallel ribs separated by grooves, the ribs having first extremities facing laterally away from the copper body, the grooves having second extremities facing laterally away from the copper body, wherein at least one of said grooves includes at least a part of a multilayer protrusion extending between said second extremities, the multilayer protrusion having at least two layers made of different materials, and wherein at least one of the two layers is made of a wear resistant material that increases locally the wear resistance of neighboring ribs.
A cooling plate for a blast furnace, said cooling plate comprising a copper body having an inner face having a plurality of parallel ribs separated by grooves, the ribs having first extremities facing laterally away from the copper body, the grooves having second extremities facing laterally away from the copper body, wherein at least one of said grooves includes at least a part of a multilayer protrusion extending between said second extremities and comprising at least one layer made of a wear resistant material that increases locally the wear resistance of neighboring ribs, wherein said multilayer protrusion comprises a first layer made of a material having a high thermal conductivity, and a second layer made of said wear resistant material and set on top of said first layer.
