国内二辊斜轧穿孔技术发展现状及未来展望

Present Development Situation and Future Outlook of Domestic 2-roll Rotary Piercing Technology

通过装备和工艺两个技术维度对当前国内二辊斜轧穿孔技术的发展现状进行了系统总结.指出目前国内二辊斜轧穿孔机装备技术无论是设计能力、制造水平、生产运营状态,还是装备性能均已经能够代表当今世界先进水平.作为当前首选穿孔机型,为适应用户对产品质量、生产效率、生产成本以及生产品种的更高要求,建议未来应该在优化二辊斜轧锥形辊穿孔机工艺设计和生产节奏以及打造智能穿孔等方面实现技术提升.

Systematically summarized in the paper is the present development situation of the domestic 2-roll rotary piercing technology based on the two technical dimensions,i.e.,the equipment and the process.It is regarded that the equipment technology of the domestic 2-roll rotary piercing mill as developed up to now has been qualified to represent the current world level in the very field no matter the design ability,manufacture level,production and operation status or the equipment performance.For the said rotary piercing mill as the primarily selected mill type at present,it is suggested to realize in the future the technology upgrade of the mill in terms of optimization of the process design and production cycle,and development of intelligent piercing technique in a bid to satisfy the higher requirements by the user with respect to product quality,production efficiency,production cost and product varieties.
