The revolutionary concept of precast refractory shapes has been well received in different industries. It involves the design, casting and dry-out of complete sections of refractory blocs off-site, under controlled conditions, in purpose-designed production facilities.
The blocks are manufactured under stringent quality control procedures, ensuring that consistent mixes of the refractory material are casted in highly accurate moulds, dried at suitable temperatures to allow for the formation of a ceramic bond and are properly cured as to achieve enhanced service life.
Precast shapes offer the added benefit of ease of installation and shortened repair times and are characterised by the following:
Consistent and controlled manufacturing process.
Unique purpose developed materials and shapes for each application.
Work done off site resulting in minimum interface with production.
Areas of higher wear can be engineered with optimal refractory materials.
Easier slag or dross removal due to lower porosity.
Less down time due to quicker installation and heat-up times are minimized.
Shapes from 1 kg to 9 metric tons, resulting in less joints and faster installation.
