Silicon steel double-roller type coating machine frame swaying device

Abstract

The invention relates to a coating technique of a silicon steel two-roll coating machine, in particular to a swaying method of a framework of a silicon steel two-roll coating machine; the method comprises the following steps: when a band steel channel line (11) is changed and results in the inconsistency of the film thicknesses of an upper coating layer and a lower coating layer, the coating machine is swayed to an axis link between an upper coating roll and a lower coating roll (5, 4) and be perpendicular with the band steel of an outlet, so as to ensure that the band steel is consistent with a contact zone (12) of the upper coating roll and the lower coating roll and the upper surface and the lower surface of the band steel are unified. The swaying angle (A) of the axis of the coating machine is 0 to 10 degrees. The coating technique can overcome the shortcoming that the film thicknesses of the upper surface and the lower surface of the band steel are inconsistent, so as to enhance the coating quality of the surface of the band steel, and realize the replacement between the upper coating roll and the lower coating roll.

Description

technical field [0001] The invention relates to the coating technology of a silicon steel two-roller coating machine. Background technique [0002] For a long time, how to evenly coat the silicon steel coating solution on the upper and lower surfaces of the strip steel, and then dry it to form a uniform and stable silicon steel coating on the surface of the strip steel has become one of the key factors to obtain good product quality one. At present, for the coating of silicon steel coating liquid, the two-roll coating machine is a coating machine with certain achievements in silicon steel units. In addition, the diameter, groove and hardness of the coating roller are also the key to determine the thickness of the coating. Usually, the silicon steel coating solution is applied with a grooved roller, such as figure 1 , figure 2 As shown, through the contact with the coating liquid and the rotation of the coating roller itself, the coating liquid can be kept in the groove...

AI Technical Summary

Problems solved by technology

However, because there is a certain groove shape difference between the upper and lower coating rollers, the upper and lower rollers will not be interchangeable, and the requirements for the roller matching of the upper and lower rollers are more stringent, which greatly increases the turnover of spare parts and production costs
