For the low alloy steel castings which are applied to Russia train bolsters and side frames, whether the low temperature impact toughness meets the requirements or not is closely related to the service life of the product and the safety of the train. In order to enable the low-temperature impact toughness of steel castings to meet the requirements, the author, firstly, on the basis of understanding the performance, metallurgic phase and material requirements of the low-alloy steel products, analyzes and researches the problems in the product trial process of casting and heat treatment according to determined process and test methods, secondly, ascertains the influence of casting height of test rod, opening time, heat treatment temperature, heating time, cooling speed and related process parameters in the process of casting and heat treatment on low temperature impact toughness of low alloy steel castings in an attempt to ensure the quality of bolsters and side frames.
