Online flushing device for drying rollers in cleaning section of annealing line

Abstract

The invention discloses an online flushing device for drying rollers in a cleaning section of an annealing line. The device comprises a tank body (1), wherein a movable guide groove (2) and a roller (3) are arranged at the upper end of the tank body (1); a flushing pipe (5) is arranged above the drying rollers (4); the two ends of the flushing pipe (5) are connected to the movable guide groove (2)through a spray pipe base (6); flushing nozzles (7) are distributed on the flushing pipe (5); and an angle rotation regulating valve (8) is further mounted at a position, close to the end part, of the flushing pipe (5). The online flushing device can realize online flushing for a plurality of pairs of drying rollers in production, is good in flushing effect, effectively solves the problem that iron mud is adhered to the surfaces of the drying rollers, and improves the quality and the production efficiency of strip steel products.

Description

technical field [0001] The invention relates to a squeeze roll in a cold rolling production line, in particular to an online washing device for a squeeze roll in the cleaning section of an annealing line. Background technique [0002] In the cleaning section of the annealing unit, the alkali brush tank and the water brush tank are equipped with squeeze rollers, which can reduce the lye in the alkali brush tank or the water in the water brush tank from being carried to the subsequent process by the strip steel, preventing water The brush tank is mixed with lye to affect the quality of the brushing water. In actual production, the iron sludge on the surface of the strip steel after being cleaned by the alkali brush and the water brush is easily adhered to the surface of the squeeze roller after being rotated and squeezed by the squeeze roller, resulting in Blocky spots on the surface of the steel strip seriously affect the surface quality of the finished product. However, it ...
