Abstract

本发明涉及一种连铸大包长水口氩封保护装置。大包长水口一端有碗口,碗口的轴心有钢流孔,大包长水口的碗口外密封固定套筒,套筒与碗口外表面之间有空腔,套筒壁上有与空腔相通的接头,套筒上有与所述的钢流孔对应的风流孔。它结构简单,氩封通气孔不会被堵死,氩气完全将钢流与空气隔绝,对钢流起到保护作用。

Description

连铸大包长水口氩封保护装置
技术领域
本发明涉及一种连铸大包长水口,特别涉及一种连铸大包长水口氩封保护装置。
背景技术
如图1所示,目前,大包长水口12的氩封通气孔11在碗口10的侧壁上,在浇钢过程中经常被溅钢溅渣堵死,起不到氩封的效果,使得钢水被二次氧化,造成质量事故。
发明内容
为了克服现有技术的缺点,本发明提供一种连铸大包长水口氩封保护装置。它结构简单,氩封通气孔不会被堵死,氩气完全将钢流与空气隔绝,对钢流起到保护作用。
本发明解决其技术问题所采取的技术方案是:大包长水口一端有碗口,碗口的轴心有钢流孔,大包长水口的碗口外密封固定套筒,套筒与碗口外表面之间有空腔,套筒壁上有与空腔相通的接头,套筒上有与所述的钢流孔对应的风流孔。
本发明结构简单,氩封通气孔不会被堵死,氩气完全将钢流与空气隔绝,对钢流起到保护作用。
附图说明
下面结合附图和实施例对本本发明进一步说明。
图1为现有技术剖视图;
图2本发明剖视图。
具体实施方式
如图2所示,大包长水口7一端有碗口1,碗口1的轴心有钢流孔2,大包长水口7的碗口1外密封固定套筒4,套筒4与碗口1外表面之间有空腔5,套筒4壁上有与空腔5相通的接头6,套筒4上有与所述的钢流孔2对应的风流孔3。
所述套筒4的内壁上固定有导流板(图中未画出)。作用一是保证空腔5的间隙均匀、固定不变,二是对引导风向,使风流孔3出风均匀。
所述的导流板为多头螺旋板。
所述的导流板为直板。
