It also can be concluded that reduction efficiency was influenced by slab thickness greatly, and slab width and steel grade have little effect on reduction efficiency.
板坯宽度与钢种对压下效率的影响较小，板坯厚度对压下效率的影响大。

Recently, it has been proven that the casting technology is advanced because the slab grinding ratio of grade 304 is on the same level at the reference plant.
