Present-day high-performance cooling systems shall be protected with high-quality refractories. The effect of hot gases, chemically aggressive substances, operating contingencies, intensive abrasive wear, and the complexity of geometrical shapes require searching for new solutions in order to create refractories that meet these requirements. Our technical solutions are applicable to the various sections of the lining of air-quenching coolers may be established using a variety of technologies: vibropacking, mortaring, and a modular lining.
