Material development

Refraline has developed its own range of monolithic refractory materials, which has undergone significant testing. The companies R&D facility enables us to develop customer specific refractory materials and set new trends. Our customer-focused approach looks at a specific refractory problem with the aim to improve the campaign life of a lining.

Materials include:

  • Conventional castables
  • Medium cement castables
  • Low cement castables
  • Ultra low cement castables
  • No cement castables
  • Phosphate bonded castables
  • High strength / wear resistant castables
  • Freeflow castables
  • Insulation castables
  • Insulation gunning
  • Conventional gunning
  • Low porosity gunning
  • Conventional mortars
  • High strength mortars
  • Ramming mixes
  • Plaster / trowelable mixes
  • Gel bonded castables

Refraline also markets the highly successful environmentally friendly tap hole clay, which contains no coal tar pitch violates (CPTV’s) and not only allows for less volatile organic compounds (VOC’s) being released into the atmosphere thereby limiting greenhouse gases, but also providing a work environment that limits the exposure of workers to VOC’S / VPTV’s, allowing healthier employees.

Refractory Precast Shapes

Precast shapes are manufactured under controlled conditions to a higher degree of completeness than castables installed in situ. This has significant advantages, as the conditions in a precast shop can be better controlled than on site and the curing process can be done prior to installation of the precast shape to avoid curing on site, which is usually part of the critical path during commissioning. Refraline Refractory & Corrosion Engineering manufactures precast shapes for a variety of industries. Our inhouse designed curing furnace and frequency controlled vibrating equipment, combined with special moulding techniques to ensure highest product quality.
