Abstract
The invention discloses a high-strength magnetoconductive steel plate which comprises a main component of Fe and further comprises the following components in percentage by mass: no less than 0.04% and no more than 0.10% of C, no less than 0.6% and less than 1.0% of Mn, no more than 0.20% of Si, no more than 0.04% of P, no more than 0.007% of S, no less than 0.02% and no more than 0.06% of Als, no less than 0.02% and no more than 0.05% of Nb, no more than 0.03% of Ti and inevitable impurities. The invention also discloses a production method of the steel plate. According to the technical scheme, by controlling the smelting chemical components and establishing an appropriate process, a cold-rolled annealed steel plate having high mechanical properties and favorable direct-current magnetic properties is obtained. The cold-rolled steel plate has high yield strength and magnetoconductive properties, and can endure a high load without deformation in use.
Description
technical field [0001] The invention belongs to the technical field of metallurgical industrial products and their production, and relates to steel plate steel strip products and their production methods. More specifically, the present invention relates to a high-strength magnetically permeable steel plate and a production method of the steel plate. Background technique [0002] For applications that require the establishment of a magnetic field, the way to increase the magnetic field strength is to use magnetically permeable materials to amplify the magnetic field strength. With the increase of the magnetic field intensity or the increase of the stress intensity caused by the movement, the magnetic permeable material is required to have at least two properties, that is, the magnetic permeable material is required to have high magnetic induction intensity and high mechanical performance (strength) index. [0003] Improving the strength of materials is generally achieved by ...
