Embodiment

[0027] In one embodiment of the present invention, the electromagnetic filter is used to separate out the iron in the emulsion, and the electromagnetic filter includes three working modes: the first working mode is to run for two hours every three hours, and the second working mode is to run every three hours Two-hour power-on operation for three hours, the third working mode is always power-on operation.

[0028] The method for controlling iron content in the emulsion comprises the following steps:

[0029] S01. Determine the deformation of the rolled piece and the material of the rolled piece, and the material of the rolled piece includes ordinary materials and special materials;

[0030] Specifically, the deformation of the rolled piece is the ratio of the absolute deformation of the rolled piece to the original thickness, the absolute deformation of the rolled piece is the difference between the original thickness and the thickness of the rolled piece after rolling, and th...

Abstract

The invention relates to the technical field of cold-rolled sheet strips, in particular to a method for controlling iron content in emulsion. The method is characterized by performing time-sharing control on power-on operation of an electromagnetic filter according to rolled piece deformation and rolled piece materials, so that the iron content in the emulsion is stabilized within a control standard, the problem of unqualified rolled pieces caused by overhigh iron content in the emulsion is solved, further, time-sharing control is carried out on power-on operation of the electromagnetic filter, the problem that the performance of the emulsion is reduced when iron in the emulsion is separated out through the magnetic filter is solved, and the method is suitable for cold-rolled sheet strips.

Description

technical field [0001] The invention relates to the technical field of cold-rolled strips, in particular to a method for controlling the iron content in an emulsion. Background technique [0002] In the rolling process of cold-rolled strips, high-pressure and large-flow spray emulsions are usually used to cool and lubricate the rolls and rolled pieces. Due to the friction between the rolls and the plate surface during the rolling process, iron powder will be produced, and the iron powder will follow the emulsification. The iron powder enters the circulation system of the emulsion. The amount of iron powder produced is related to the lubricating ability of the emulsion, the surface roughness of the roll, the characteristics of the rolled material and the absolute deformation. If the iron content in the emulsion is too high, the rolled piece will be damaged. The cleanliness of the plate surface after processing is reduced, and the emulsion remains. The existing technology is t...
