This symposium will continue its past focus on the development of “state of the art” refractory liner materials and on the advancements needed in material performance driven by changes in industrial processes or by the development of new processes. Drivers for change; such raw material availability, environmental concerns, controlling energy loss in processes, liner materials for evolving industrial process, or the need for relevant information on refractory material properties or on the processes contained by refractory materials will be discussed. Symposium topics will include sustainable refractory raw materials and product development; the installation of refractory material and the evaluation of finished refractory properties; the analysis of refractory wear/failure, thermal management, and thermodynamic process modelling; and how to address the education needs of refractory users and manufactures in a changing workforce. Contributed papers will include the achievements and challenges from the perspective of refractory producers, users, and academia; and will focus on shaped and unshaped (monolithic) refractory materials composed of natural and/or synthetic raw materials.
Session Topics

CP-1 Raw materials needs

  • Natural raw material and their characterization and performance – including changing industry needs, reductions in energy consumption to produce raw materials, and raw material sustainability
  • New/improved refractory raw materials and additives (natural and synthetic) to meet changes in refractory performance needs (wear, corrosion, or thermal management/insulation)
  • Raw material phase relationships and reactions occurring during product installation, sintering, or use that impacts microstructure development and/or product performance
  • Spent refractory reuse/recycling

CP-2 Product testing and quality control

  • Testing and improving physical properties; such as thermal shock, spalling, hot strength, fracture resistance, creep, thermal conductivity, and MOE
  • Quality control and analytical tools used to improve refractory product quality, consistency, performance
  • Evaluating and controlling monolithic materials property changes that occur during storage, mixing, installation, drying, and firing; including those caused by composition and additives
  • Monitoring process variables and/or material properties related to refractory failure during service
  • Microstructure analysis or phase changes as it relates to material performance (using SEM, TEM, cathodoluminescence, high temperature confocal laser microscopy, optical microscopy, or other analytical tools)
  • Advances in refractory manufacture, installation, and/or system repair/maintenance

CP-3 Specialized refractory use / issues

  • Iron and steel
  • Non-ferrous metals
  • Preheat and hot work furnaces
  • Cement
  • Glass and ceramics industry
  • Petrochemical, gasification, and waste incineration
  • Industry wide environmental and recycling issues
  • Needs in energy management/coolant water conservation

CP-4 Modelling and simulation of the process environment

  • Thermodynamic modelling and its use to understand/control refractory properties/performance through predictions of material interactions
  • Thermal and stress management through modelling (thermal profile, materials diffusion, crack propagation, sintering, grain boundary motion, phase transformation, etc.)

CP-5 Refractory failure analysis

  • Analysis of refractory liner corrosion/wear caused by slag, molten glass, metal, hot gases, particulates, or combinations of them targeting improved refractory performance
  • Determining the causes of refractory failure and the use of that information to make necessary system changes

CP-6 Refractory materials for novel or advanced applications

  • Fabrication and performance of ceramic liner materials made by additive manufacture
  • Electrically conductive/non-conductive liner materials for magnetohydrodynamic systems
  • The use of refractory grain as a stable structure for processes catalysts or as oxygen carriers in chemical looping combustion
  • Other novel application requiring high temperature severe service materials or protective barriers (including battery materials, high temperature microwave processes, or high speed re-entry vehicles)

CP-7 Future refractory testing and refractory education needs (refractory producers, users, and industry)

  • Refractory education needs brought about by the changing workforce, industrial environments, or changing process environments – what training/education is needed to meet those needs
  • Needs for refractory wear or industrial process monitoring to ascertain refractory wear, material stability, or process performance

CP-8 Refractory materials and manufacturing process changes related to global decarbonization

The reduction of fossil fuel use and subsequent CO2 emissions is causing industrial processes to be re-engineered, bringing about different refractory liner materials needs. This session will discuss drivers for change; such raw material availability, environmental concerns (including the need to reduce CO2 emissions), controlling energy loss in processes, liner materials for evolving industrial process, or the need for relevant information on refractory material properties or processes contained by refractory materials. Examples of process changes include but not limited to:
  • Iron and steelmaking practices shifting from the blast furnace/basic oxygen furnace process route to a direct reduced iron/electric arc furnace route.
  • Other carbo-thermal/non carbo-thermal processes are being studied for potential CO2 reductions, along with their possible impact on containment material needs. This would include processes for the production of Al, Cu, glass, and/or cement.
  • Some industrial chemical processes, such as gasification used to produce synthesis gas for chemical and power generation, are being evaluated for lower temperature processing or for the use of non-fossil energy carbon sources (such as plastics). Many of the process changes will need a re-evaluation of refractory containment materials for material performance/service life.
