Abstract

PURPOSE: To provide a nonoriented silicon steel sheet with a uniformized irol loss value and stabilized magnetic characteristics by adding B to a low C-low sol. Al-Si steel in a certain balance ratio to the N content of the steel and further adding a very small amount of a rare earth element.
CONSTITUTION: This nonoriented silicon steel sheet consists of ≤0.015% C, 1.5W 3.5% Si, 0.05W1.0% Mn, 0.005W0.08% sol. Al, ≤0.015% S, ≤0.10% O, ≤0.005% N, 0.4W2.0 B in a B/N ratio, a 0.001W0.020% rare earth element and the balance Fe and inevitable impurities. Molten steel adjusted to the composition of specified range is cast and rolled by an ordinary method to manufacture the steel sheet of high quality. The compsn. provides a high class nonoriented silicon steel plate having stabilized magnetic characteristics and low iron loss.
