Method for treating steel for directional electromagnetic steel plate and method for producing directional electromagnetic steel plate

A surface temperature of a slab is decreased down to 600 °C or lower between start of continuous casting (step S2) and start of slab reheating (step S3). The surface temperature of the slab is held at 150 °C or higher between the start of the continuous casting (step s2) and the start of the slab re...

description A surface temperature of a slab is decreased down to 600 °C or lower between start of continuous casting (step S2) and start of slab reheating (step S3). The surface temperature of the slab is held at 150 °C or higher between the start of the continuous casting (step s2) and the start of the slab reheating (step S3) . The surface temperature of the slab in the slab reheating (step S3) is set to not lower than 1080 °C and not higher than 1200 °C.
