【摘要】 对某炼钢厂四流小方坯连铸机上新安装的20 t中间包进行了水模型研究,用染色剂显示了中间包中的流动状态。结果表明,加挡墙后中间包内钢液的流动情况明显改善,且流场很大程度上受挡墙上孔位置的影响,而且孔的位置靠上时更能避免底部的短路流。更多还原

【Abstract】 The water model of 20 t four-strand billet caster tundish in a steel plant was studied. The flow state of the molten steel in tundish was shown using coloring agent. The results show that the flow of the molten steel in tundish is improved obviously after adding baffle, and the flow field is largely influenced by the hole position of baffle. When the position of the hole closes to the top, it can avoid the short circuit flow.更多还原
