摘　　要：825初轧机承担轧制方坯和扁坯任务,其机架前后的辊道与开坯主机同样重要,要适应各品种钢钢锭的开坯,不仅主机要正常,轧机前后辊道必须正常运行;辊道良好的结构运行状态才能保证辊子传输和运送一定的坯料轧件。通过分析现场825轧机机前辊道经常出现故障的原因。改进辊道的自由端的结构,在不改变整个辊道的基础上,通过重新设计轴承选型和配置,在有限的空间内焊接延长辊道端部,提高了辊道使用寿命3-8倍,效果明显,更好地满足825初轧开坯品种钢生产的需要。825 blooming mill undertakes the special function of rolling square billet and flat billet.Not only the main engine but also the front roller table shall operate normally,Its good structure and running state can ensure that the driven roller transmits the blank and rolled piece;By analyzing the causes of frequent failures of the front roller table of the mill;Improving the structure of the free end of the roller table,On the basis of not changing the whole roller table,by redesigning the bearing selection and configuration,the end of the roller table is welded in a limited space to prolong the service life of the roller table by 3-8 times,the effect is obvious.It can meet the needs of the production better.
