For the purpose of supplying useful information to manufacturing organizations, and of systematically examining the effects of temperature and time of annealing on the domestically produced low silicon steel electrical sheets, a series of experiments has been performed. The results show that the lowest obtainable values of core loss of samples box-annealed in its own atmosphere are approximately P_(10)=2.3 watt kg, P_(15) = 5.2 watt/kg, 30% lower than the permissible values set in ROCT 802-41 for э1A.

为了提供生产上有用的数据,为了考察国产低矽钢片在不同温度不同时间的条件下退火以后的效果,我们进行了具有相当系统性的关于退火条件的实验。实验结果表明:在较850℃为低的温度退火不同时间或多次退火,可使铁心损失达到同一最低值;在高于950℃的温度退火以后,即令再度在较低温度退火,也不能达此最低值。此最低值约为:P_(10)=2.3瓦特/千克,P_(15)=5.2瓦特/千克,较ГOCT802-41中对Э1A规定的最高值低30%。

Some points about the measurement of ferromagnetic (core) losses by using alternating current bridge method have been invastigated, showing that as the source of the bridge for the measurement of magnet, its internal impedance must be constant and must be much less than that of the bridge arms, the core losses calculated from Fq (7)coincide with the result of wattmeter.

Magnetio parameters of equivalent fundamental frequency, such ascomplex permeability μ, inductance permeability μ_L, magnetic dissipation factorD_m and quality factor Q, as well as the total core loss P_c can be measured by theautomatic bridge technique. In bridge circuit, the priniple of vector impedance ra- tio measuremeut is applied. Fundamental frequency character is obtained by multi-plication device to overcome the difficulty due to the non-linearity in A. C. magneticmeasurement. Dual-slope A/D conversion method is used for measuring variousratios. With some other auxiliary circuits, parameters of hysteresis loop, such asmaximum induction B_m, magnetizing force H_m, peak permeability μ_p, residual inductionB_T, coercive force H_c and squareness ratio B_T/B_m can be also measured in a singleinstrument. All digital results of measured parameters are displayed or printed inmagnetic unit system for direct reading. Accuracy of measurement is ±1~3%.Working frequency is from 50Hz to 5kHz. Measuring function and range change arecontrolled by logic circuit. This design automatizes the measurement of all A. C. mag-netic properties and results in convenience of designing an automatic measurementsystem for magnetic parameters by microprocessor.
