Abstract

本实用新型提供了混铁炉出铁时,铁水连续、自 动测温用传感器的探头,其特征是在探头的中心部位 有透镜,将接受的铁水红外辐射聚焦于石英光纤端头 上,光纤与检测仪相接。该探头设有吹氮管,通过吹 氮冷却探头并吹散探头前的烟气与粉尘。

Description

本实用新型涉及用于铁水温度,尤其是混铁炉出铁时所用的测温传感器的探头。
在炼钢过程中,为保证炼钢用铁水的质量,必须随时测定铁水的温度,现有的测温装置一般采用热电偶接触式或光学辐射非接触式等,前者由于铁水罐罐体大,深处与表面、中心与边缘有明显的温度差,有时渣层厚,插入还很困难,而且混铁炉出铁水时冲击力大,操作难度也大;后者由于出铁水时,出铁口上方温度可达二、三百度,且有粉尘、烟雾,因此给一般的辐射测温仪的使用带来不少困难。
本实用新型的目的是提供一种在混铁炉出铁时自动检测铁水温度用探头。
本实用新型的目的是这样实现的:在探头的中心部位装有透镜,将接受铁水的红外辐射通过透镜聚焦于光纤电缆的石英光纤端头上,并通过光纤传输到检测仪上,该探头外层设有氮气管,其出口氮气经弯曲的出口恰能覆盖镜头表层,以起到除去探头前的粉尘、烟气与冷却的作用,探头中的透镜、光纤端头是通过隔着氮气通道及石英平镜来封闭的。
本实用新型因为其主要部件只有光纤、透镜及吹氮气管,无需特殊设备,只要安装在距铁水流一定距离的位置上,即可自动接受铁水红外辐射,为铁水温度的自动测定提供了探头,并减轻了劳动强度。
下面结合附图说明本实用新型的构成。
本发明包括氮气出口(1)、探头管套(2)、石英平镜(3)、氮气通道(4)、钢管(5)、透镜(6)、光纤端头(7)、塑料套管(8)、光纤电缆(9)、氮气入口(10)。光纤电缆(9)与检测仪相连。
本探头使用时,只要把探头安装在离铁水流一定距离处,通过光纤电缆接到检测仪上,即可自动、连续测定铁水温度。

Claims (2)

1、一种包括透镜(6)、光纤端头(7)、氮气通道(4)的铁水测温探头,其特征在于:该探头还有一个能把铁水的红外辐射由透镜(6)聚焦于光纤端头(7)上,并输送红外辐射到检测仪的光纤电缆(9)。
2、如权利要求1所述的探头,其特征在于:
(1)探头中的透镜(6)、光纤端头(7)是通过石英平镜(3)与氮气通道(4)封闭的,
(2)氮气通道(4)的末端还有一个能使氮气覆盖住探头镜头的弯曲氮气出口(1)。
