Abstract

Taking the ladle used by a factory as an example, a three-dimensional finite element model of the ladle was established, and the temperature distribution law of the lining during the ladle transportation was studied using the finite element analysis software ANSYS, which verified the good thermal insulation performance of the nano thermal insulation layer, and analyzed and compared the temperature and distribution law of the refractory lining under the two working conditions of the heavy ladle and the empty ladle. The results show that due to the change of the boundary conditions in the empty ladle state, the temperature change trend of the working layer and slag line layer along the thickness direction changes, but the overall temperature distribution of other layers does not change much; The temperature of the inner liner generally tends to be high inside and low outside, with a large temperature gradient along the radial direction. Therefore, during the production process, it is necessary to try to avoid sharp changes in the temperature of the inner liner, and regularly maintain the refractory materials to extend the service life of the ladle.
