Abstract

The as-cast microstructure of niobium-containing slab was observed and characterized by metallographic microscope and scanning electron microscopy. The results show that the as-cast microstructure of the niobium-containing silicon steel slab is ferrite and a small amount of pearlite. There is no obvious difference in the microstructure of the niobium-containing silicon steel slab, and the as-cast (Cu, Mn) S, in addition to niobium carbon, nitride precipitation, AlN mainly strip and square, sulfide and niobium carbon, nitride was mainly Spherical or ellipsoidal. The number of precipitates in the slab is small but larger in size, and the size of precipitates is in the range of 100 nm to 500 nm.
