本文概述了用电渣熔铸方法,研制ZGl7—4MoPH水电站用导叶的工艺情况.介绍了所用备、结晶器、自耗电极、渣系、电参数、工装工艺、炉前工艺以及设研制过程中如何解决一些关健技术难题等:报告了某些检测分析结果.电渣工艺可以大幅度提高工件的某些性能,尤其是不改变强度指标的前提下,显著提高了冲击韧性指标.电渣工艺代替锻造方法生产外型复杂的工件,不仅技术上是可行的,而且具有一系列优越性,特别是由于大量节约金属,在经济上是颇有竞争力的.
In this paper, the process of electrogalvanizing casting is introduced to develop the guide vane for ZGl7-4MoPH hydropower station.Presents the preparation, crystallizer, consumable electrode, slag system, electrical parameters, tooling, pre-furnace technology and research and development process How to solve some key technical problems: Reported the results of some testing and analysis.Electroslag process can significantly improve certain properties of the workpiece, especially under the premise of not changing the strength index, significantly improve the impact toughness.Electrochemical slag The production of workpieces with complex shapes instead of forging is not only technically feasible but also has a number of advantages, particularly economically competitive due to the large metal savings.
