Φ325钢管矫直机主传动系统设计
摘 要
在市场行情日益紧张的今天,钢管行业供需矛盾进一步恶化,无缝钢管厂库存创新高,个别民营钢厂因连续亏损出现停产现象。为了在竞争中取得优势,只有靠质量取胜。目前,国内无缝钢管的生产主要还是依靠热轧技术,而在热轧的过程中,钢管会存在纵向弯曲和圆度误差,这些缺陷是通过矫直工艺来予以消除的。 因此,矫直工艺决定了无缝钢管的几何形状,同时也影响其力学性能。在矫直过程中,如果矫直机调整合适,可以消除无缝钢管的纵向弯曲和圆度误差,并能适当提高其力学性能。目前,国内外的矫直技术飞快发展,其中以多辊矫直机应用最为广泛。本次设计的主要目的是进一步掌握矫直机主传动系统,并对主其要部件进行设计和计算校核。在查阅大量文献和了解相关知识,并且到鞍山钢铁集团公司无缝钢管厂?219、?159和PQF三条国内先进的生产线进行实习调研,掌握现代轧管机的发展及设备结构特点状况后,确定了两台电机通过万向接轴直接带动工作辊工作的总体传动设计方案。通过对矫直机的主要力能参数的计算,合理选择电机,联轴器、减速器主要零件以及万向联轴器和连接轴,并进行强度计算和校核。同时,确定润滑方式,并进行经济性和环境保护的分析。

The Main Driving System Design Of Φ325Roll Tube Straightener
Abstract
In todays increasingly tight market conditions, supply and demand further deterioration of the steel industry, high inventory seamless steel pipe plant, individual private steel mills shut down due to continuous losses occur phenomenon. In order to gain advantage in the competition, only by the quality to win. At present, the domestic production of seamless steel tubes mainly rely on hot rolling, and in the course of hot rolling, steel buckling and there will roundness error, these defects are to be eliminated by the straightening process. Thus, the straightening process determines the seamless steel pipe geometry, and also affects its mechanical properties. In the straightening process, if appropriate adjustment leveler, eliminate buckling and roundness error of seamless steel tubes, and properly improve its mechanical properties. At present, domestic and foreign straightening technology fast development, in which mufti-roll leveler most widely used. The main purpose of this design is to further understand the main drive system, and its main components should be designed and calculated check. After a review of the extensive literature and understand the relevant knowledge, and Anshan Iron and Steel Group Seamless Steel Tube Plant ?219, ?159 and PQF three advanced production lines internship research, development and equipment to master the structural features of t
