The utility model relates to a temperature measuring probe for molten steel. The temperature measuring probe includes a temperature measuring gun barrel (1) with a copper head (5) with a temperature measuring gun (1), and a temperature measuring probe (3) with a temperature measuring couple head (4) at the top, and the temperature measuring gun barrel (1) is inserted into the temperature measuring probe (3) and makes the temperature measuring gun copper head (5) and the temperature measuring gun (5) and the temperature measuring probe (5) and the temperature measuring probe (1). The temperature measuring couple head (4) contacts; at the temperature measuring gun barrel (1) and the temperature measuring probe (3) tail end equal length corresponding place is provided with at least one positioning protruding (2), the positioning protruding (2) and the temperature measuring probe (3) inner wall interference fit so that the temperature measuring gun body (1) is fixed at the center of the temperature measuring probe large paper tube (3). When the temperature measuring gun is inserted into the steel water, the contact of the temperature measuring probe and the barrel of the barrel of the temperature measuring gun is good, the possibility of the failure of the temperature measurement is reduced, the success rate of the temperature measurement is improved, and the temperature of the molten steel is obtained in time and accurately.

,特别涉及一种测量钢水温度的测温探头。
技术介绍
冶金行业,在炼钢生产中,稳定的钢水温度是连铸工艺的基本要求之一。钢水温度偏低会使钢水发粘,夹杂物不易上浮,导致铸坯表面缺陷,水口冻结浇铸中断;钢水温度偏高会使耐材侵蚀严重,夹杂物增多,吸气严重,坯壳薄易拉漏,产生中心偏析缩孔和裂纹。测量钢水温度的方法一般采取测温探头直接插入钢水中,通过二次仪表显示温度数值,允差±1℃。测温探头主要由测温偶头与大纸管构成。偶头主要有正负偶丝焊接在补偿导线上,外装有防渣帽,大纸管起保护测温枪作用。测量钢水温度时,将测温探头装在测温枪上,仪表准备灯亮,可以进行测温,把测温探头插入钢水,深度以300-400mm为宜,测量时不要测到炉壁或渣子上,当二次仪表得到结果时,应立即提枪,不得连续测量温度,否则会造成温差波动,如果测温失败需要更换新的测温探头再次插入钢水中测取钢水温度。分析测温失败原因发现,现有技术中的测温探头装在测温枪上,也就是测温枪铜头通过大纸管插入测温探头底部,由于大纸管与测温枪枪身为间隙配合,当测温枪插入钢水中时,受钢水浮力的影响,大纸管 ...
