<p>A high-temperature resistant blast pipe is primarily intended for delivering gas, such as oxygen, and, when appropriate, solid material to metallurgical processes, and incorporates a layer of refractory material comprising a refractory mixture of solid particles and an alkali-silicate based binder. The blast pipe is characterized in particular in that the major constituent of the binder is of the type polymerized alkali silicate.</p> |
