Study on Spraying Technology of Super-hard Ceramic Corrugated Roll

with the rapid development of the carton packaging industry in China, intense marketing competitions urge the companies to give more consideration on the qualities and costs of carton products. The core part, corrugated roll, plays an important role in carton products quality and economic benefits, but the traditional corrugated roll can't meet the requirements any more. In order to improve the working life of corrugated roll and meet the requirements of the wider and wider web and the faster and faster speed of carton producing line, the study on the spraying technology of super-hard ceramic corrugated roll was performed. In this paper, the corrugated roll was respectively treated with three techniques including ceramic rod flame spray, high velocity oxygen flame WC/TiO2 and electroplated diamond, dimension variances of flute shape were observed, the surface performances were tested and the good processing technology was determined.
