Abstract:

Proceedings of the second ACI sponsored Refractory Concrete Symposium. Ten papers are presented. Topics include recent advances in refractory concrete technology; problems and solutions in using these materials as liners in coal gasification equipment, aluminum melting and holding, refining and petrochemical operations, and steelmaking; nondestructive testing and evaluation; and repair techniques.

Abstract:

Plastic refractories fail from anyone of five general causes. One of these is improper installation. A case history is presented of a large monolithic job where several fundamentals of installation were not followed and subsequent replacement was required.

Abstract:

The purpose of this paper is to provide a description of performance criteria for refractory concretes, or castables, in the melting, holding, and transfer of aluminum alloys in ingot plants. Refractory concretes in these applications have three mechanisms of failure which are attributed to anomalies in refractory installation, thermomechanical stability and chemical stability. Chemical stability indicates the refractory concrete's resistance to corrosive effects of chlorine gas, molten metal, and alkali vapors.

Abstract:

Refining and petrochemical operations, such as fluid catalytic cracking units, naphtha reformers, incinerators, and furnaces subject refractory linings to a variety of aggressive actions, such as erosion, spalling, slagging, and chemical attack. A number of different types of monolithic refractory material are used to resist these actions. The types of refractory failure commonly experienced in refineries and petrochemical plants are discussed and methods of repairing or replacing the deteriorated areas are outlined. The effect of placement techniques, curing conditions, and start up procedures on the serviceability of repaired sections is also discussed.

Abstract:

Early failures of monolithics are always a disheartening experience to the supplier, but they often are useful learning experiences as well. A number of field problems are described. These problems were solved by such adjustments as changes in material selection, improvements in existing materials and/or the development of new materials, changes in design, improvements in installation technique and modifications to the bake out procedure.
