Sink roll scraper device is one of the most important auxiliary equipment of continuous hot galvanizing production line, it is used to clean up the attachment on the roll and make the roll ‘s surface certain smoothness in operation period, because nodulation without slag could effects the quality of steel's surface. Sink roll scraper device is always in poor working conditions, which made the device wear more, corrode more and have a shorter life. The people of Jiuquan Steel Group galvanizing line technical personnel developed a safe and reliable scraper device after two years of long service technological innovation which have a longer life and could effectively get rid of slag that comes from zinc pot sinking.Meanwhile, The device settle down a series of problems such as the deformation of screw clamping, nut wearing, poor lubrication and a problem that sink roll surface pressure moved by force is not stable. The application of the device is prefect, and the comprehensive cost of the production unit is reduced. The surface quality of galvanized sheet is well improved.
