Abstract

本实用新型公开了一种适合生产φ4.0mm-φ12.0mm线材的高线吐丝弯管。它的外形与对现有吐丝弯管相同,不同的是内径φ为25mm-32.5mm范围内的任一数值。由于吐丝弯管内径小,与线材的间隙小,所以使用寿命提高20%-100%,吐丝后的成形圈形变得规则,生产成本明显降低,轧机作业率显著提高,产品质量改善。

Description

一种高线吐丝弯管
技术领域
本实用新型涉及一种钢铁行业高速线材轧钢生产线设备,尤其是吐丝弯管。
背景技术
目前国内外钢铁行业高速线材轧钢生产线用的吐丝弯管是一根渐开线曲线形式的整体弯管,吐丝弯管的内径范围为φ33mm-φ40mm的几种型号,用这种吐丝弯管生产φ12.5mm-φ26.0mm规格的线材时寿命很高,吐丝圈形良好;但是在生产φ4.0mm-φ12.0mm规格的线材时,由于线材直径细小,与吐丝弯管内径的间隙大,而且轧速高、纯轧时间延长,产生摩擦剧烈现象,导致吐丝弯管的寿命大幅度降低,且吐丝后的成形圈形不规则。这一问题成为国内外高线装备制造厂家和线材生产厂家所关注的焦点:有的采取组合式(内衬磨损后可更换)吐丝管设计、有的对吐丝弯管的曲线进行优化设计等办法,但实际应用效果并不理想。
发明内容
本实用新型的目的是解决现有吐丝弯管供生产φ4.0mm-φ12.0mm的线材时寿命短、吐丝后的成形圈形不规则的技术问题,提供一种高线吐丝弯管,供生产φ4.0mm-φ12.0mm规格的线材使用。
为解决上述问题,本实用新型的外形与对现有吐丝弯管相同,不同的是内径φ为25mm-32.5mm范围内的任一数值。
其积极效果是:
在生产φ4.0mm-φ12.0mm规格的线材时,换下原φ33mm-φ40mm的吐丝弯管,使用φ25mm-φ32.5mm相应直径的吐丝弯管。由于吐丝弯管内径小,与线材的间隙小,所以使用寿命提高20%-100%,吐丝后的成形圈形变得规则,生产成本明显降低,轧机作业率显著提高,产品质量改善。
附图说明
图1是本实用新型高线吐丝弯管的外形图;
图2是图1的断面图。
具体实施方式
下面结合图1和图2进一步说明本实用新型的技术方案。
从图中可以看出,本实用新型高线吐丝弯管是一根渐开线曲线形的整体弯管,内径φ在25mm-32.5mm范围内多种直径规格。
