What does "P" in Baosteel's silicon steel sheet "B23P090" mean?
According to different products, cold rolling process is divided into multi stand mill rolling and single stand rolling, in which single frame rolling mainly produces oriented silicon steel products.
Silicon steel rolling for hot rolling and cold rolling processes of two, using the traditional hot rolling production process silicon steel currently has been rarely used, mainly for hot rolling and cold rolling process to produce two, known as the cold-rolled silicon steel products.
The English name is silicon steel sheets. It is a soft ferromagnetic alloy containing low carbon content. Generally, the silicon content is 0.5 ~ 4.5%. The addition of silicon increases the resistivity and maximum permeability of the iron, reduces the coercivity, the core loss (iron loss) and the magnetic aging.
