Abstract


Torpedo car is one kind of huge equipment used to transport fluid-steel in most of the steel companies, native and foreign. Even a very little decline of the fluid-steel temperature, in the torpedo car, will enhance the energy cost obviously. This is a bad thing to the preprocessing of fluid-steel, energy saving, iron making process and production management.In order to improve the life of the torpedo car body and solving the temperature decline of the fluid-steel, the research was done in this paper, ANSYS software was used to analyze the temperature field, thermal flux field and thermal stress field of 320-Tons Torpedo Car. In the analysis, considering the non-linear change of physical parameters which flow the temperature change and the non-linear of the radiation, the non-linear temperature field and thermal flux was simulated with finite element software. The temperature and Thermal flux distribution in different layer and the temperature decrease were analyzed according to the original temperature of fluid-steel, temperature of atmosphere and heat-character of different hot-bearing material. The heat lost between out surface of torpedo car body and atmosphere caused by the change of natural convectional heat-change modulus was analyzed. Fluid-steel’s temperature decline caused by reducing the work layer and adding a heat-keeping one were discussed in this article, too.The result was tested by experience. In the experience, the result got form the finite element analysis was tally to the temperature of the torpedo car body, tested by infrared temperature measuring equipment.The result of this article was helpful to the usage, maintain, energy saving and increasing the life of the torpedo car.
