1·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。
2·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.
目前，以304钢种为代表的板坯修磨率达到了样板厂水平，板坯表面质量达到了设计要求，工艺设计被证明是合理的。
3·Based on the theoretical expression of reduction efficiency, the effects of steel grade and slab size on reduction efficiency were investigated.
结合轻压下效率的理论计算式，考察了钢种、板坯断面对连铸板坯轻压下效率的影响规律。
