US 10,954,574 B2 · Water pipe collection box and stave cooler support

Abstract

A water pipe collection box and stave support for a cast copper stave cooler body panel that has disposed within it a circuit of water pipes with a number of loops each with an inlet end and an outlet end, and all such inlet ends and outlet ends clustered together in a single group that exits a backside of the copper stave cooler body panel. A cast copper stave cooler body panel that has disposed within a circuit of water pipes with a number of loops each with an inlet end and an outlet end, and all such inlet ends and outlet ends clustered together in a single group that exits a backside of the copper stave cooler body panel. A blast furnace having stave cooler body panels variously profiled to fit inside, and where each has disposed within it a circuit of water pipes with a number of loops each with an inlet end and an outlet end, and all such inlet ends and outlet ends are clustered together in a single group that exits a backside of each copper stave cooler body panel.

Dependent claims

A stave cooler for supporting and cooling refractory in a pyrometallurgical furnace, comprising:

an outer metal panel housing comprising a pure copper casting;
an inner cooling fluid circuit comprising a cooling fluid inlet, a cooling fluid outlet and one or more cooling fluid pipes or cooling fluid passageways disposed within the outer metal panel housing;
wherein each cooling fluid pipe and/or passageway enables cooling fluid to pass through and between the cooling fluid inlet and outlet;
and
a single external manifold made of carbon steel and comprising a hollow manifold housing and top plate for receiving couplings, and that is attached to support the weight of the stave cooler inside on a blast furnace shell;
wherein the single manifold has one or more inlet pipes, or defines one or more inlet passageways, for providing cooling fluid to the cooling fluid inlet of the cooling fluid circuit of the outer metal panel housing;
and
wherein the single manifold has one or more outlet pipes, or defines one or more outlet passageways, able to receive cooling fluid from the cooling fluid outlet and cooling fluid circuit in the outer metal panel housing;
wherein, all the cooling fluid inlets and outlets are gathered together inside the single external manifold for external coolant connection outside the blast furnace shell.

A stave cooler, comprising:

a cast copper stave cooler body panel that has disposed therein a circuit of water pipes with a number of loops each with an inlet end and an outlet end, and all the inlet ends and outlet ends clustered together in a single group that exits a backside of the copper stave cooler body panel;
a steel anchor frame roughly in the shape of a flat, thick O-ring that surrounds the inlet ends and outlet ends clustered together and set in cast copper flush at the surface at the exit on the backside;
a series of footer openings placed around a lower embedded perimeter of the steel anchor frame that are entrained with copper that froze inside during a copper casting of the stave cooler body panel, wherein the steel anchor frame is thereby mechanically locked into the cast copper stave cooler body panel;
a pipe collection box made of steel, hollow, open at two opposite ends, and one end continuously welded along its entire perimeter to a top exposed face perimeter of the steel anchor frame, wherein all the inlet ends and outlet ends clustered together are passed through inside for external connections of circulating liquid coolants;
wherein, the entire stave cooler is fully supportable inside a blast furnace by the pipe collection box.
