Abstract

The invention provides a continuous production process and device of a high-silicon steel magnetic ultrathin strip. A conductive metal strip is taken as a base material, the conductive metal strip istaken as a cathode and pure iron is taken as an anode in an aqueous solution in which iron ions and nano silicon powder are dissolved, a Fe / nano Si composite material magnetic film is prepared throughcodeposition of the iron ions and the nano silicon powder on the surface of the conductive metal strip; and after the prepared Fe / nano Si composite material magnetic film is subjected to low-temperature stress relief heat treatment, the Fe / nano Si composite material magnetic film is stripped from the conductive metal strip, and a Fe / nano Si composite material magnetic ultrathin strip is prepared.The structure of the prepared high-silicon steel magnetic ultrathin strip is a solid solution with the silicon content being 4.5wt% - 8wt% or a composite material magnetic ultrathin strip with a large number of Si nano particles evenly distributed in an iron-silicon solid solution with the silicon content being 4.5wt% - 8 wt% in a dispersed mode, and the prepared Fe / nano Si composite material magnetic ultrathin strip has higher mechanical properties.

Description

technical field [0001] The invention belongs to the field of magnetic materials, in particular to a continuous production process and device for high-silicon steel magnetic ultra-thin strips. Background technique [0002] Silicon steel has excellent soft magnetic properties and is widely used in the fields of electric power, electricity, communication and national defense. Silicon steel is usually used in the form of silicon steel sheets. High-performance silicon steel sheets need to meet: 1) High initial magnetic permeability and maximum magnetic permeability to ensure higher magnetic flux density (magnetic induction) in a given strength of magnetic field, which can reduce the volume of motors and transformers; 2) The iron loss is small to reduce the eddy current loss and hysteresis loss in the alternating magnetic field. For this reason, the silicon steel sheet is required to have the largest resistivity and the smallest thickness; 3) The magnetostriction coefficient is ...
