板坯连铸辊列图与液心凝固技术分析

Analysis Roller Diagram and Soft Reduction of Slab Caster

板坯连铸机中,扇形段是关键部位。钢水在此区间由液态凝固成固态,应控制好板坯液心凝固的位置,并且由组成扇形段的排列辊进行拉伸矫直,所以辊列图和液心凝固的选择是决定扇形段和板坯质量的重要因素。

The segments are the most important parts of the slab caster, the liquid steel becomes the slabs in this area, the position of soft reduction should be controlled and the slabs be stretched and straighted by the rollers which are made of the segments, the troller diagram and the soft reduction are the keys whicn determine the quaility of the segmentit and the slabs.
