Cold-rolled strip steel electrostatic oiling chamber structure

Abstract

The invention relates to the field of cold-rolled strip steel electrostatic oiling processes, in particular to a cold-rolled strip steel electrostatic oiling chamber structure which optimizes oiling control precision, thereby improving the oiling quality. The cold-rolled strip steel electrostatic oiling chamber structure comprises an oiling chamber, an upper knife beam and a lower knife beam are arranged in the oiling chamber separately, a heating oil tank and a knife beam oil supply servo control system are arranged at the top of the oiling chamber, the knife beam oil supply servo control system communicates with the upper knife beam through an upper oil way, and the knife beam oil supply servo control system communicates with the lower knife beam through a lower oil way. In actual use, the oil quantity can be adjusted more sensitively, and thus the oil injection quantity can be flexibly adjusted according to actual oiling needs, and even thicknesses of strip steel surface oil films are guaranteed. In addition, because the heating oil tank is arranged, the oil pressure, the oil temperature and the liquid level of oil in the heating oil tank can be precisely controlled, and therefore the controllability of oil film coating is ensured. The cold-rolled strip steel electrostatic oiling chamber structure is especially suitable for strip steel oil film coating processes.

Description

technical field [0001] The invention relates to the technical field of electrostatic oiling of cold-rolled steel strips, in particular to a structure of an electrostatic oiling chamber for cold-rolled steel strips. Background technique [0002] The anti-rust problem of cold-rolled finished strips has always been one of the key quality control points in the production process. During the production process, the electrostatic oiling technology is mainly used for the anti-rust treatment of the strip surface. Not only from the perspective of reducing cost and increasing efficiency, reducing environmental pollution, it is necessary to ensure that the thickness of the oil film is controlled as small as possible on the basis of strip steel rust prevention. At the same time, the thickness of the anti-rust oil on the strip is required to be within the accuracy range specified by the requirements, so as to prevent the strip from rusting due to the thin oil film. [0003] In the produ...

AI Technical Summary

Problems solved by technology

In order to ensure sufficient anti-rust requirements, cold-rolled strip manufacturers are forced to increase the thickness of the oil film, resulting in a sharp increase in the production costs of themselves and downstream manufacturers, and at the same time causing corresponding environmental pollution and pollution control costs.
