Abstract A large amount of water spray can cause error in radiation temperature measurement of slab surface in continuous casting secondary cooling zone. In order to find out the influence of water spray on the radiation temperature measurement of high temperature slab， in this paper an experimental device was designed to study the influence of water spray on the radiation temperature measurement error of high temperature slab. Experimental study of the influence of water spray on the radiation temperature measurement error is carried out by using the experimental device. The study shows that when the water spray exists， the two-color radiation temperature measurement is more accurate than the monochromatic radiation temperature measurement. Its relationship with the actual temperature， water volume and thickness of water mist is T＝T双－（aQ＋b）h－cQ－d. The relationship between pressure and air pressure is ?T＝kh－b1. The parameters are determined through experiments. The research results can provide accurate temperature measurement for continuous casting process.
