Abstract
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.
Claims13
A blast pipe which is intended for delivering a material which can be a gas, or a solid, to molten metal in metallurgical processes and which is capable of withstanding high temperatures, said blast pipe having internal and external surfaces and including at least one layer of refractory material on at least one of said surfaces comprising:
- a refractory mixture of solid refractory particles and an alkali silicate based binder, wherein the improvement being that the major constituent of said binder is a polymerized alkali silicate.
