This training course is designed to give a detailed discussion of the subject of refractory technology as related to high-temperature requirements for different industries. The course will emphasize on the practical aspects of refractory selection, installation, and repair techniques in a number of industrial applications. In order for the course material to suit participants with or without formal training and/or scientific background in the subject, the course will be delivered such that most of technical terms and concepts will be clarified by both scientific definition and examples. The course material will be prepared so that easy follow-up of the lectures and subject in general is achieved. The course is divided into nine main areas: Principles of hot processes and their requirements, Properties of refractory materials (mechanical, thermal and corrosion resistance), Refractory compositions and structures and their relation to property and performance, Refractory selection criteria, Refractory manufacturing methods, Configurations and installations techniques, Refractory system design, Performance in service, Quality and Reliability considerations. The course is designed such that no previous background in metallurgy is necessary. The course can, also, be tailored for specific needs if required by certain participants.
