Abstract

The invention discloses a change method for a working roll of a roll coating machine. The change method comprises the following steps: detecting a new roll; judging whether the new roll meets change requirements or not; disassembling a protective cover of the roll coating machine and an old roll of the roll coating machine; clearing the mounting position of the new roll on the roll coating machine; arranging the new roll at the mounting position; adjusting the position of the new roll to a position required by production, and fixing the new roll; mounting a sealing device; restoring the protective cover; and starting the roll coating machine, carrying out detection and putting the roll coating machine into use after detection shows that the roll coating machine is qualified. According to the change method for the working roll of the roll coating machine, the whole change process is divided into a plurality of steps, and specification and control are carried out on each step, so that the standard specification of the change process of the working roll is realized, the change precision of the working roll is ensured, the machining precision of the roll coating machine is accordinglyensured, and the machining quality of the product is ensured.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method for replacing work rolls of a roll coater. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] In order to ensure the performance of the galvanized steel strip, passivation treatment is generally carried out on the surface of the galvanized steel strip, and the passivation treatment is realized by a passivation roller coater. [0004] The working roll of the passivation roller coater is an important part of the equipment. The working roll includes a pick-up roll and a coating roll. The pick-up roll is used to bring the passivation solution in the passivation tank to the coating roll. The cover roll is in direct contact with the strip, and the passivation solution is applied to the surface of the strip to form a passivation film. [0005] When the passivation r...
