Abstract

The invention provides a magnetically soft alloy strip surface oxide layer removing method and a removing device thereof, and belongs to the field of magnetically soft alloy material surface treatment. The method comprises the steps that a transmission mechanism is utilized for conveying a magnetically soft alloy strip, tensioning is conducted through a tensioning device, meanwhile, the magnetically soft alloy strip is closely attached to a grinding device, grinding is conducted through rotation of the grinding device, meanwhile, mixed air blowing is conducted on the surface of the magnetically soft alloy strip, and grinding and ground magnetically soft alloy strip packaging are conducted at the same time. Operation is simple, manual operation is replaced, and the grinding efficiency is improved by about 5 times.

Description

technical field [0001] The invention relates to the field of surface treatment of soft magnetic alloy materials, in particular to a method for removing an oxide layer on the surface of a soft magnetic alloy strip and a removal device thereof. Background technique [0002] Because of its high magnetic permeability and low coercive force, soft magnetic alloy strips are widely used in the production of current transformer cores, magnetic heads, magnetic shielding and other devices. They are used in industries such as military industry, aerospace, electronics, precision instruments and meters. At present, it is mainly obtained by rolling. Whether it is hot rolling or cold rolling, there will be an oxide layer and pits on the surface of the soft magnetic alloy strip during the rolling process. These defects determine whether it can be used for the above industry and accessories. [0003] At present, the oxide layer on the surface of the soft magnetic alloy strip is usually manua...
