密封水套是镍冶炼矿热电炉电极密封装置的关键零件,安装在电极孔附近,并部分伸入炉内,在800℃左右高温、高强磁场及浓SO_2气体环境中工作。七九年十月以前用不锈钢焊接制作,使用半年均因烧蚀、气体腐蚀、电化学及应力腐蚀而损坏。冶炼厂工程技术人员大胆革新,改革原结构,设计了铜合金密封水套。一、选用新材料根据水套工作条件,制造这种零件的材料
Sealed water jacket is the key part of the electrode sealing device of nickel smelting thermoelectric furnace installed in the vicinity of the electrode hole, and partially extended into the furnace, working at about 800 ℃ high temperature, high magnetic field and concentrated SO2 gas environment. Before October 1979, it was produced by stainless steel welding and was damaged by ablation, gas corrosion, electrochemistry and stress corrosion for half a year. Smelter engineering and technical personnel bold innovation, the original structure of the reform, the design of the copper alloy seal water jacket. First, the choice of new materials According to the water jacket working conditions, the manufacture of such parts of the material
