Description

一种轧件的扭转导卫
技术领域
本实用新型属轧钢用辅助工具领域,具体涉及一种在轧机轧制过程中,轧件的出口导卫。
背景技术
    在轧钢生产工艺过程中,轧件每轧制一定的道次后需要进行翻钢,继而进行立轧。在连续式轧制过程中,轧件的翻身是依靠扭转导卫来进行的。通常情况下,扭转导卫在生产状况下短时间内磨损较大,造成扭转角度误差。材料不耐热,即在使用过程中,温度升高后,表面粘连,被磨损下来的钢渣和氧化铁皮,粘结在磨擦的表面,从而对轧件表面造成划伤。轻度划伤可以在轧件后消除,但重度划伤造成产品缺陷。
实用新型内容
   本实用新型所要解决的技术问题是提供一种轧件的扭转导卫
,耐磨损、使用寿命长。
为实现上述目的,本实用新型提供一种轧件的扭转导卫,所述的扭转导卫,为轴对称结构,扭转导卫的出口断面为六角形,其六角形的顶角α比轧件顶角角度小,可减少边端的磨擦。
优选地,扭转导卫出口断面的扭转角度为23°,所述扭转导卫的顶角为80°-89°,这样,轧件在扭转过程中,以槽底做为主要受力面,轧件的尖角不接触导卫,减小了磨擦,避免划伤两侧边的金属。
优选地,所述扭转导卫的顶角为86°。
优选地,扭转导卫的材质为Cr20Ni35,使耐热温度提高到1150℃。
本实用新型所提出的一种轧件的扭转导卫,减小了轧件在扭转过程中扭转导卫的磨损,既耐磨又耐热,使用寿命长,由划伤造成产品缺陷的现象不在出现,节省了材料和成本,降低了消耗,改善了产品质量,提高了企业经济效益。
附图说明
图1是本实用新型提出的一种轧件的扭转导卫结构示意图。
具体实施方式
本实用新型具体实施方式结合附图,进行详细的描述。
一种轧件的扭转导卫,所述的扭转导卫,为轴对称结构,扭转导卫的出口断面1为六角形,其六角形的顶角α比轧件顶角角度小,可减少边端的磨擦。
优选地,扭转导卫出口断面的扭转角度为23°,所述扭转导卫的顶角α为80°-89°,这样,轧件在扭转过程中,以槽底2做为主要受力面,轧件的尖角不接触导卫,减小了磨擦,避免划伤两侧边的金属。
优选地,所述扭转导卫的顶角为86°。
优选地,扭转导卫的材质为Cr20Ni35,使耐热温度提高到1150℃。
本实用新型所提出的一种轧件的扭转导卫,减小了轧件在扭转过程中扭转导卫的磨损,既耐磨又耐热,使用寿命长,由划伤造成产品缺陷的现象不在出现,节省了材料和成本,降低了消耗,改善了产品质量,提高了企业经济效益。
