Problems solved by technology

Especially since the implementation of constant speed pouring in slab continuous casting, there have been more stringent requirements on the temperature and composition of refined molten steel, and the accuracy of manual temperature measurement and sampling can no longer meet the requirements for the quality of molten steel in the next process. Accurate temperature measurement and sampling during the refining process is of great significance to improving the accuracy of molten steel temperature measurement and smelting quality, reducing raw material consumption and labor intensity of employees

[0003] When refining manual temperature measurement and sampling, it is difficult to meet the specified requirements for the position and depth of the insertion point of the temperature measurement gun, and the stability of the manual temperature measurement gun will deteriorate if it is heated for a long time, which will affect the accuracy

Therefore, the accuracy of the temperature value obtained by manual temperature measurement and sampling is poor, and the composition of the shape fluctuates, which affects the production efficiency of the continuous casting machine and the quality of the slab
