High gas temperatures, sulphuric compounds, phosphoric acid and highly aggressive hydrofluoric acid require coordinated lining materials as well as experienced detailed engineering designs for various processing stages and critical areas, such as inlet ducts or outlets.
Sealing layers consisting of rubber, Rhepanol or synthetic resin systems are applied in these areas. Lightweight refractory bricks, foam glass and acid-resistant ceramic qualities are utilised as insulation in the various processing zones. For process conditions involving fluorides and fluoric acid, carbon bricks provide reliable protection against chemical attack and higher temperatures. We can also supply refractory brick qualities specially designed for use in converters or other special areas.
