Symposium Papers

Volume:

57

Abstract:

Because of the numerous advantages of specialty refractories, such as availability, cost, ease of installation, etc., in industrial applications, their utilization has increased significantly in recent years. A large portion of that increase involves the usage of refractory concrete, and thereby the effect of water content or consistency on properties and performance acquires increased importance.

Abstract:

In summary, I have seen a big improvement in the construction and use of more modern and sophisticated gunning and placing equipment used in the refractory industry. The introduction of the open top rotary guns, the use of special nozzle designs for better wetting and the placing of refractory castable using the dry guns along with the concrete placing head has opened up a new market. I feel you will see in the near future more sophisticated equipment for predampening refractory materials and because of these improvements more materials will be gunned and placed.

SP57-09

Date: 

January 1, 1978

Author(s):

R. L. Wessel

Publication:

Symposium Papers

Volume:

57

Abstract:

The use of refractory castables in steelplant applications is expanding continually, and their use has been accelerated by periods of energy and/or fired-refractory-material shortages. . .Projections for the future of refractory concretes in the steel industry suggest a trend toward the use of high-purity and synthetic raw materials and greater interest in composity materials containing metallic fibers.
