提高产品质量,降低每吨成品钢板的金属、燃料和电力消耗,提高轧机的生产能力,减少操作人员是国内外发展厚板生产的主要目标.在可逆式轧机生产钢板时,金属的损耗在很大的程度上取决于板形和边部与端部切损.长期以来,实际上是保持延伸和宽展大约相等的系数比例,作为控制板形的唯一方法.这个方法在大多数情况下效益很小,使用受到限制。在顿涅茨黑色冶金科学研究所进行了一系列理论和试验研究,包括板坯侧面和端面在立辊与粗轧机延伸和宽展时,压下量对板
Improve product quality, reduce metal, fuel and electricity consumption per tonne of finished steel, improve rolling mill production capacity and reduce operator’s main goal of developing thick slab at home and abroad.When the steel is produced by reversing mill, the loss of metal is very high To a large extent, it depends on the shape of the plate and on the edge and on the end of the cut. For a long time, the ratio of the coefficients of approximately equal extension and spread is actually maintained as the only way to control the plate shape. This method is effective in most cases Small, limited use. A series of theoretical and experimental studies were carried out at the Donetsch Institute of Black Metallurgy Science and Technology, including the side and end of the slab as the vertical rolls and the roughing mill extended and spread,
