A 1 day interactive seminar, covering the following topics:
Introduction to Refractories
The introduction consists of a description and definition of what we regard as refractory materials, including such factors as chemistry, melting points and limiting temperatures of use.
Categories
Here we discuss the different way we can categories the various materials focusing on chemical properties, but also touching on the terms in general industry use.
Bricks or Monolithics?
The various criteria for making this crucial decision are discussed, and further details on the critical properties of the differing types are listed.
Installation
In this section, the most important factors relating to proper placement are listed and discussed. Practices concerning Bricks and shapes, Plastics, Castables, Gunning, and Shotcreting are included, with comments on their general application, and criteria for choice.
Dry-out & Heat-up
This subject is largely misunderstood and the reasons behind its requirements are rarely fully appreciated. These are presented in some detail from a basic level.
Design Factors
Although this is an advanced area, some introduction to the critical factors in Mechanical and Thermal design, including the importance of Expansion allowances and Interface temperatures.
Lining Wear & Failures
Here we explore the various failure mechanisms from a forensic point of view, especially the different types of Spalling and effect of 'tramp" compounds in the operating environment.
Reading the Data Sheet
This is the major technical communications channel between supplier and user. The facts disclosed on this are often misinterpreted by those unfamiliar with test methods and 'jargon'. These are addressed through a 'generic' data sheet for a mainstream product.
The Tender process
This section is specifically designed for non-engineers, e.g. Purchasing officers, or operators with limited refractories knowledge. It basically outlines the essential factors to be addressed in the forming of the RFT and how the responses should be evaluated.
Safety Issues
This section discusses some of the refractories specific issues, discussing such materials as:
Silica, Chrome, Fiber, and issues such as Overhead protection & Confined Space entry.
Workshop/Current issues
In this last section, we open the floor and discuss problems raised by the participants, or discuss other major contemporary issues .
The course/seminar is positioned at a practical level, keeping technical jargon to a minimum, while communicating the main points and issues of this discipline.
