摘要
Abstract
Based on the structural characteristics of runner hub used for Gezhouba hydropower station,the capacity of smelting equipment and the lifting capacity of crane,the pouring process of 5 ladles combined pouring and then 2 ladles pouring in the riser was practiced and cutting the riser in the pit at 880-900℃are formulated in this paper.The parameters of tapping,re-heating and pouring for each ladle was determined via the pouring process with 5 empty ladles,then the runner hub with net weight of 122 tons was successfully poured.Cutting riser in the pit and the annealing process was performed to make up for the shortage of crane capacity and ensure the smooth production of castings.关键词
