Abstract
The utility model relates to a low-consumption leveling liquid isolating device. The low-consumption leveling liquid isolating device is arranged at one end, close to a working roll, of the upper surface of an antiwind guide plate which is arranged above a strip steel at an outlet of a temper mill. A movable support is connected on the antiwind guide plate and can do rotational motion around a connecting shaft. A flexible scraping plate on the movable support can move along with the fixed support. A driving device is connected with the antiwind guide plate and the movable support and can drive the movable support to do rotational motion. A position sensing device is arranged in the driving device. A water baffle is arranged at the lower end of the antiwind guide plate, and drain holes are formed in two sides of the water baffle. The space between the two drain holes along the width direction of the water baffle is larger than the width of the strip steel. According to the low-consumption leveling liquid isolating device, effective and low-energy-consumption seal can be formed at the joint between the antiwind guide plate in the temper mill and the working roll. The condition that leveling liquid passes through a gap between the working roll and the antiwind guide plate and is splashed on the surface of the strip steel to enable the leveling liquid residues to be left on the finished strip steel is avoided. Consequently, the working roll above the strip steel and the antiwind guide plate are combined into a complete leveling liquid blocking layer, and the leveling liquid residues on the surface of the finished strip steel are reduced.
