Abstract
The invention discloses a silicon steel sheet used for a transformer. The silicon steel sheet comprises, by percentage, 0.07-0.1% of C, 3-3.4% of Si, 0.2-0.3% of Mn, 0.05-0.07% of Cr, 0.02-0.03% of P, 0.1-0.2% of S, 5.8-6.0% of Al, 0.04-0.06% of Ni, and the balance Fe. The silicon steel sheet is high in magnetic conductivity and specific resistance, good in magnetization and low in cost, internal stress is good, current consistency is good, and the components are simple.
Description
Technical field
The present invention relates to transformator parts technical field, be specifically related to a kind of stalloy for transformator.
Background technology
Transformator utilizes mutual inductance principle.Transformator is that the principle utilizing electromagnetic induction is to change the dress of alternating voltage
Putting, main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage becomes
Change, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformator) etc..Can divide by purposes
For: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer,
Oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc..
Transformator is in electric equipment and radio-circuit, and transformator is commonly used for buck/boost, coupling impedance, peace
Full isolation etc..In electromotor, no matter it is that coil movement passes through magnetic field or Movement in Magnetic Field passes through fixed coil,
All can in coil induced potential, these two kinds of situations, the value of magnetic flux is the most constant, but with coil intersecting chain
Magnetic flux quantity but has variation, and this is the principle of mutual induction.Transformator is exactly that one utilizes undesirable mutual electromagnetic inductance to answer,
The device of voltage of transformation, electric current and impedance.The most basic form of transformator, including two groups be wound with wire it
Coil, and each other inductively to claim to unify.
Stalloy is the silicon-iron soft magnetic alloy that a kind of carbon containing is extremely low, and general silicon content is 0.5～4.5%.Add
Silicon can improve resistivity and the maximum permeability of ferrum, reduces coercivity, core loss and magnetic aging.Mainly
It is used for making the iron core of various transformator, motor and electromotor.
The performance of existing stalloy needs further Optimal improvements.
Summary of the invention
For the problems referred to above, the invention provides a kind of stalloy for transformator, there is higher magnetic conductance
Rate and resistivity, service life is long.
In order to solve the problems referred to above, the technical scheme that the present invention provides is:
A kind of stalloy for transformator, each composition and percentage ratio thereof is: C:0.07 0.1%, Si:3
3.4%, Mn:0.2 0.3%, Cr:0.05 0.07%, P:0.02 0.03%, S:0.1 0.2%,
Al:5.8 6.0%, Ni:0.04 0.06%, surplus is Fe.
Preferably, each composition and percentage ratio thereof are: C:0.08 0.1%, Si:3.2 3.4%, Mn:0.22
0.3%, Cr:0.06 0.07%, P:0.025 0.03%, S:0.12 0.2%, Al:5.85
6.0%, Ni:0.04 0.055%, surplus is Fe.
Preferably, each composition and percentage ratio thereof are: C:0.085%, Si:3.3%, Mn:0.28%, Cr:
0.065%, P:0.025%, S:0.12%, Al:5.85%, Ni:0.05%, surplus is Fe.
Preferably, each composition and percentage ratio thereof are: C:0.09%, Si:3.25%, Mn:0.22%, Cr:
0.068%, P:0.028%, S:0.15%, Al:5.9%, Ni:0.045%, surplus is Fe.
(1) carbon can increase the magnetic hystersis loss of stalloy.
(2) silicon can weaken the ill effect of carbon, i.e. reduces magnetic hystersis loss, can improve again pcrmeability simultaneously
And resistivity, the aging action that the magnetic that prolongation life-time service brings degenerates.
Compared with prior art, the invention have the benefit that
The stalloy pcrmeability of the present invention and resistivity are high, and magnetizability is good, and internal stress is good, and Current compliance is good,
Composition is simple, low cost.
