Abstract
The tuyere for a blast furnace, the tuyere having a body part (10) with cooling means extending rearwardly from a nose portion of the body (10). In order that a failure of the tuyere when in service does not result in large quantities of water entering the furnace, the cooling means are constituted by a plurality of heat pipes, the heat pipes being formed either in tubes (12) cast in the body part (10) or being formed in holes (112) drilled in said body part.
Claims6
A method of manufacturing a tuyere for use in a blast furnace, the method comprising the step of casting in a mold a tuyere body with one or more cast-in tubes so that said tube(s) extend generally longitudinally of said tuyere body between its wall thickness, and thus extend rearwardly from near a nose portion of said body, and the subsequent step of forming in situ a low pressure, boiling/condensing heat pipe of each of said tube(s) by installing a wick material, evacuating the tube(s), introducing a working fluid, and sealing the tube(s).
