"Refractories for monolithic lining of
hot metal mixer and installation technique" were developed independently
by our company to replace the conventional brickwork to give good integrity,
higher safety and good insulating effect. Consequently, the problem of roof
brickwork collapse has been overcome and the service life of slag line and tap
hole zone has been significantly improved. This achievement was approved as a
science and technology achievement organized by Department of Science and
Technology of Henan Province and granted national invention patent. The
technology has been successfully applied in domestic hot metal mixers with
capacities of 300, 600, 900 and 1300 tons, with service lives of 1 to 3 times that
of the original brickwork linings.
According to application and service conditions, we have developed
mullite castables, mullite-zirconia castables, high alumina-silicon carbide
castables and high alumina-mullite castables for roof, slag line, tap hole and
bottom respectively. We can offer full service from lining design, refractory
supply, installation to working out operation regulations, maintainance, etc.
