Abstract

A foundry core for the production of small diameter elongate holes within a casting comprises a refractory tube within which is arranged a reinforcement. The reinforcement may be soft iron or Cu wires and the tube woven or knitted refractory fibres, such as glass, carbon or asbestos. The core is removed by extracting the wires and pulling out the tube. <IMAGE>
