中文摘要 | 煉鋼廠轉爐設備,屬於轉動磨損機件或自然劣化之組件,在維護上,必需進行 定期更換;為降低因停機上之生產調度影響,或環保之顧慮,抑或在能源回收上之減 少,我們針對部份之設備組件,進行材質改良改善。經過多年之觀察,結果良好,不 僅節省鉅額之備品及施工費用,且大幅地增強設備調度之穩定性。 這些改變材質之實例包括: 1.#1∼#3轉爐誘引抽風扇葉片材質改為特殊不�袗�。 2.煉鋼一廠#1,#2二次集塵抽風扇葉片表面黏貼陶瓷片。 3.煉鋼廠一,二號轉爐氣儲槽之橡膠氣囊,材質由CR改為NBR。 此外,針對廢氣處理設備之護罩膜管,目前正進行氣體側表面之熔射噴焊開發 工程,預期可以大幅降低膜管之磨損速率,有效提升護罩之使用壽命。 |
英文摘要 | There are some wearing parts for rotation machines and natural degradation parts for moving or fixed equipments in BOF Plant of Steelmaking Department. For maintenance purpose, it has to replace these parts by regularly. In order to reduce machine shutdown period, less the environmental protection concerns, and short the loss of energy recovery, we perform the material amelioration for some equipment parts. After some years observation, the service life of these parts has been extended much longer than before. The examples are as follows: (1)Impeller material of I.D. Fan was changed to special stainless steel on #1∼#3BOF. (2)Anti-abrasion ceramic liner was attached onto the impeller surface on #1∼#3BOF No.1 & 2F.E.Fan. (3)The rubber seal of No.1 & 2 L.D. Gas Holder was changed to NBR material from original CR on #1∼#6 BOF. Furthermore, we are under testing a thermal spray method onto the gas side of hood membrane pipe in L.D.Gas treatment equipment to lengthen the service life. |
