Abstract
To maintain the safety of an open-type hot-metal car and to reduce wheel-rail wear during transportation, simulation models of the main components of such car were built using Pro/E software and then tested. In particular, the Pro/E models were imported into ADAMS/Rail for assembly and then used to construct a complete hot-metal car dynamic model. Locomotive wheel-rail attack angle, wheel-rail lateral force, and wear index were used as evaluation parameters during the simulation to analyze the effects of bogie parameter, rail parameter, and speed of the hot-metal car on wheel-rail wear. An improvement scheme for reducing wheel-rail wear was proposed based on the result of the dynamic simulation, wherein wheel-rail wear and curving performance were analyzed and compared. The simulation provided an important reference for evaluating and improving the dynamic performance of the hot-metal car. The applied effect showed that the improvement scheme is effective.

Summary
A hot-metal car is a special vehicle for transporting hot iron for iron works. With the rapid development of the steel industry, fundamental standards for hot-metal cars have been established in terms of safety, efficiency, and load capacity. Steel manufacturers aim to further develop hot-metal cars. The advantages of appropriate capacity, low cost, huge market demand, and technical difficulty have made hot-metal cars with the 140 t capacity the most competitive in
