Abstract:
A method of cooling a component formed from cast refractory material having two faces that, during use, is subjected to high heat on one face thereof, comprising the steps of:a) providing at least one passage through the interior of the cast refractory material component that extends continuously between spaced openings located near opposite ends of the passage and which are on the other face of the component; and,b) positioning the cast refractory material component so that, when the component is subjected to heat on the one face thereof during use, the spaced openings are at differing vertical levels and communicate with a body of relatively cooler ambient air at the other face, with at least one of the openings defining an inlet to the passage that is located below at least another of the openings defining an outlet to the passage, so that ambient air may enter the passage inlet, may become convectively heated and rise upwardly through the said at least one passage in the absence of any mechanical inducement to air flow, and may discharge from the passage outlet, thereby to establish a flow of ambient air through the passage to cool the component as it is heated on the one face thereof.
