Abstract: The principle,structure and characteristics of a fully automatic thermal shock resistance tester using 3D laser scanning technology were introduced.The tester was designed according to the relevant requirements of the thermal shock resistance test through water quenching in GB/T 30873—2014.Compared with the traditional testing method,it can automatically complete the measurement and calculation of the damage of the test end face,data archiving and recording and shutdown judgement during the thermal shock resistance test.The application results show that the tester greatly improves the testing efficiency and accuracy,eliminates the human error,and provides rich data and image information for the result analysis and process analysis of the thermal shock resistance.

Key words: laser scanning method, thermal shock resistance, automatic testing, refractories
