D-gun can make surface strengthening and functional coating layer for the roll in high temperature section of CGL and CAL, so that life time is effectively extended for various kinds of roll, strong guarantee is given for stable running of production line. This technology has been successfully widely applied in Baosteel, Shougang, Masteel, Bengang, Ansteel, Tangsteel, Baogang ,Tagal and overseas steel plants.
D-gun is a kind of technology which is to mix fuel with oxygen to generate explosion energy in pulse type, powder is heated and speeded up in gun, and shot to the surface of base of part to be coating layer. By means of selection of special coating material and optimized spraying process, it can make functional protective coating layer for high temperature oxidation, wearing and anti-corrosion and anti-build-up coating layer.
