摘要
在剖析德国Fuchs和美国PTI喷枪保护套的结构特点和损坏原因后,研制出可拆分体式喷枪保护套。该保护套由底板和围罩两部分组成,分别埋纯铜管和各自铸造、加工成型,并由连接件组成整体。经杭钢电炉两千多炉次的使用,证明具有冷却效果好、使用寿命长、成本低和拆装方便等特点,成功地替代了国外进口件,并具有独立自主知识产权。
After dissecting the structure characteristic and the damage reason of the ejector sleeve from FUCHS in German and from PTI in America, we develop a new type of ejector sleeve. This sleeve includes a lower copper-cast plate and a copper-cast cover, which a pure copper tube is embedded in each copper-cast part. The ejector sleeve is experimentally used in Hanggang Arc-furnace, and its life is more than two thousands heats .The better cooling efficiency and the longer life and the lower cost and the convenient dismantlement etc. are confirmed.
