Why Choose this Training Course?

Refractoriness is the ability to withstand high temperatures. In general, any material which in service greater than 600 C0 is called refractory. Refractories are vital components of industrial manufacturing and are used in just about every type of industrial process that utilises heat and, in many cases, chemical processing.

The right definition is that refractories should withstand high temperature, resistance to thermal and thermo chemical load, posse’s high-volume stability, resistant to erosion and abrasion, be tough, and resistant to chemical corrosion etc. There is no refractory material which posses all these properties 100 %. Overall it is a compromise with all these properties. Choice of refractories depend on the operating and mechanical conditions of the kiln.

The right choice of refractory material can lead to the safe, low maintenance and cost-effective protection of vital industrial heat processing equipment for a five to ten-year period. However, the wrong choice can lead to downtime, equipment failure and accidents.

The aim of this AZTech training course is to gain knowledge about the classification of refractory and insulation materials, their chemical and physical properties, conditions for their use and application. The delegates will become well-versed in the use of suitable refractory materials and thermal insulation materials for the type of equipment in practice and be able to design the possibilities of solving their application.

This training course will feature:

  • Types of Refractories and Selection
  • Properties of Refractories
  • Manufacturing methods of Refractories
  • Refractories Wear, attack and Failure
  • Testing Methods and Safety

What are the Goals?

Refractories are at the centre of process, manufacturing and petrochemical industries. The engineer is, in particular, interested in safe containment of heat related processes. Hence, this training course focuses on the central areas of the selection and safe use of refractory materials and guides the delegates in developing both fundamental and practical understandings of key issues. Delegates will be able to recognize refractory material, divide refractory materials according to their characteristics and make informed decisions about the application of refractory ceramic materials in practice that will be used in a variety of industries.

Who is this Training Course for?

This training course is suitable to a wide range of Technical professionals but will greatly benefit:

  • Technical & non-technical personnel in process and manufacturing industries with a need to understand and discuss fundamental issues related to the use of refractory materials.
  • Maintenance and project engineers, production engineers, trainee mechanical engineers and plant operators.
  • Non-experienced personnel needing a basic understanding of refractory materials concepts

How will this Training Course be Presented?

This AZTech training course will utilize a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes combined sound engineering principles, methods, and applicable codes & standards and best industry practices. Case studies and examples will cover a range of levels, making the course also suitable for non-technical staff.

The training course combines structured and focused presentations and discussions of topics covered with relevant examples and question & answer sessions to maximize the benefits to the participants. Participants will be provided with comprehensive course notes and copies of all presentation material. These will be very valuable for detailed study and future reference.
