Course Description
Refractories are considered the critical factor for the successful and reliable operation of many high-temperature industrial processes. They are often a major cost item both in general maintenance and also in terms of unscheduled downtime of production units arising from premature material failure. There is a continuous need for technical professionals involved in the operation of these processes to be well informed about new technologies related to the refractory material and their physical and technical characteristics.
This training course is designed to provide a detailed discussion of refractory technology as related to high-temperature requirements for different industries. The course will be focused on the practical aspects of refractory evaluation, selection, installation, maintenance, and repair techniques in many industrial applications.
The Training Course Will Highlight ?
- Designing characteristics of refractories: Thermal, Mechanical, and Chemical
- Methods of testing refractories
- Efficient installation of refractories for various applications
- Root cause analysis of failures encountered in the operation
- Guidelines for inspection, maintenance, and repair of refractories
