Abstract
The severe working conditions often puts the conticaster rolls out of operation. In this paper, the detonation spray coating was used to try and protect the rolls. Using the orthogonal test, suitable technological parameters were obtained. The experimental results show that the coatings processed were dense with good bonding to substrate as well as high resistance to high temperature oxidation and wear. Reports from the in-service test at Bao Shan Steel Company indicate that the Cr 3C 2–NiCr detonation spray coating produced by authors has at least doubled the roll life.
