We offers the widest range of ceramic beads for heat treatment. Our95% Alumina Ceramic Beads is manufactured by dry press method and sintered at temperature upto 1650° C. The production is under careful material selection of high grade alumina spray drying granulation from what we call calcined alumina, thus the quality stability is maximally ensured. It enjoys high temperature resistance, excellent insulating property, and efficient thermal conductivity and heat transfer. Thanks to its property, the ceramic beads is widely used as components of flexible ceramic heating pad and channel heaters at operation of pre and postweld heat treatment; Welding process, stress-relieving, ship-building, other heat-resistance-environment. Compared with hot press method, it proves higher density, higher surface finish and better uniformity, and be repeatedly used much longer.Compared with the traditional electric heater energy consumption can be reduced by 30%.
