小规格带肋钢筋四切分轧制工艺开发和优化实践

Development and Optimum Practice on Four-strand Splitting Rolling Process for Small-size Ribbed Steel Bar

介绍了柳钢棒线型材厂小规格带肋钢筋四切分工艺的孔型、导卫装置和和轧制通道的设计特点,以及生产中的优化措施。目前Ф12mm带肋钢筋四切分班产比三切分班产提高30%。

The design characteristics of pass, guides and guards, rolling channel of four-strand split- ting rolling process for small-size ribbed steel bar, and the optimized countermeasures during production in Bar and Section Plant were introduced. The shift production of four-strand splitting rolling process for φ12 mm ribbed steel is 30% higher than that of three-strand splitting rolling process.
