Abstract Improving the ratio of continuous casting is an effective measure to improve the production efficiency and rolling yield, save energy and reduce cost, and is also a key index to reflect the smelting level of steel mills. The viscosity standard of continuous casting protective slag recommended by China's metallurgical industry——internal cylinder rotation method is not clear because of its the guidance of the test method, which leads to large fluctuation of the measurement results in practical work. Combined with the actual work,the test conditions of the viscosity of continuous casting protective slag were studied. The results show that when the carbon content of the sample is less than 0.5%, the length of the constant temperature zone of the furnace body meets the requirements, the temperature fluctuation of the constant temperature zone is less than 3 ℃, the graphite head immersed in the melt was controlled at 10-20 mm, the furnace body was sealed, and the excellent graphite dry pot is used, the furnace body is sealed. The determination result is stable and reliable.
