高线无孔型轧制技术的开发与应用

无孔型轧制是一项可以优化线棒材生产的先进技术。本文依托新兴铸管盘螺生产机组开展了无孔型轧制工业试验和研究，具体介绍新兴铸管股份公司在高线车间粗中轧1-12^#轧机上采用了无孔型轧制工艺并介绍了其工艺特点，通过制定合理的轧制工艺参数正确的使用轧辊、导卫，解决开发中发现的问题，并分析了高线无孔型轧制技术带来的效益。实践证明，无孔型轧制技术开发成功后，可优化轧制工序，能达到统一坯料、去除氧化铁皮、节约生产时间、降低轧辊和导卫消耗、降低劳动强度和减少固定资产投入等目的。无孔型轧制技术具有广阔的发展应用前景，技术价值和经济价值较大，特别适合小型材生产的老线改造和新线建设。

Development and application of grooveless rolling technology for high speed wire rod mill

The grooveless rolling is an advanced technology which can optimize steel bar and wire rod production. The industrial experiment and research of grooveless rolling technology are conducted on the continous high speed wire rod mill of Xinxing ductile iron pipes stock Co.,Ltd.o The grooveless roiling technology at 1H and 12V stands of mill coiled reinforced bar produetiong in rough and intermediate rolling of Xinxing were introduced. The characteristics,test schemes,parameters design of this techlogy were specifically described,and its economic benefit was analyzed. Practice shows that grooveless rolling can optimize rolling sequence and can help achieve the purposes like unifying billets,descaling,saving productiong time ,lowering roll and guide consumption,reducing work strength and reducing fixed assets investment etc. With greater technical and eeonomicvalues,this technology has broad development and application perspective,esp.in the remoulding of old system and constructiong of new system in small shape production.
