摘要：

The effects of heating rate and surface oxidation on magnetic induction of thin-gauged 3% Si-Fe strips have been investigated. Magnetic induction increased with increasing final annealing temperature. Before and after 1150 degrees C, the planar orientation of grains shifted from (100)[011] to (110)[001], resulting in magnetic induction higher than 1.90 T. Magnetic induction after final annealing was higher in case of a faster heating rate. This is because enough time for growth of (110) grains is given in the case. Irrespective of transient annealing temperature, magnetic induction after final annealing was mostly higher than 1.90 T. A maximum, 1.97 T, was obtained at a transient annealing temperature of 800 degrees C. This is because iron oxide formed at 800 degrees C inhibited the surface-energy-induced selective growth of (100)[011] grains during heating up to 1200 degrees C.
