Abstract
A cooling plate for use in a blast furnace is described. The cooling plate contains a copper body having an inner face containing ribs parallel therebetween, having first extremities opposite therebetween and separated by grooves having second extremities opposite therebetween. At least one of these ribs contains at least one housing located between its first extremities and containing at least one insert made of a wear resistant material that increases locally the wear resistance of this rib.
Claims21
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 ribs includes at least one housing located between said first extremities and including at least one insert made of a wear resistant ceramic that increases locally the wear resistance of said at least one of said ribs, a base of the at least one housing being on a plane vertically spaced apart from a base of the groove.
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 extending vertically away from the copper body, 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 ribs includes at least one housing located between said first extremities and including at least one insert made of a wear resistant material that increases locally the wear resistance of said at least one of said ribs, a base of the at least one housing being on a plane vertically spaced apart from a base of the groove, said at least one housing having a cavity holding said at least one insert.
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 ribs includes at least one housing located between said first extremities and including at least one insert made of a wear resistant material that increases locally the wear resistance of said at least one of said ribs, wherein at least one of said grooves comprises at least a part of a multilayer protrusion extending between said second extremities and comprising at least one layer made of said wear resistant material that increases locally the wear resistance of neighboring ribs.
