中文摘要 | 中鋼壹號高爐(簡稱 #1BF )內容積為 2434M^3, 第二爐代於 1985 年 1 月 25 日 Blow in,於 1996 年 9 月 21 日 Blow out,共計操計了 11 年 8 個月, 累計爐代鐵 水產量為 18,511,736 噸。 為了減少爐內待清殘留爐料量, 進而縮短大修更新時間,#1BF 第二爐代之停風作業採用降 料位至鼓風嘴高程之空吹停爐作業方式。 1996 年 9 月 20 日早上 06:00 開始依計劃降料 位操作, 待料位到達 24.5 米、爐頂氣分析值中氧含量≧ 0.5 %,且由鼓風管窺規孔中所 見之鼓風嘴空前吹狀況符合標準,遂於 9 月 21 日早上 01:07 進行高爐氣隔離作業。降料 位操作開始後約 21.5 小時,爐頂氣中氧含量開始爬升≧ 5 %,9 月 21 日早上 06:50 料 位約 25 米時,順利完成 #1BF 第二爐代停風作業。 |
英文摘要 | Second campaign of CSC No.1 blast furnace started on January 25, 1985 and ended its life of 11 years and 8 months on September 21, 1996 after producting 18.51 million tons of hot metal. The blow out operation was performed by lowering the stock line to the tuyere level with aim to reducing the remained materials and to shortening the relining period consequently. The burden descending operation was started at 6.00 a.m. September 20, 1996. After stock level approaching to 24.5 m and both top gas analysis O �砥� 0.5% and empty blow condition being confirmed from blow pipe peep sight, gas cut was executed at 1.07 a.m. September 21. Approximately after 21.5 hours of burden descending operation and top gas condition of 5% O ��, the blast furnace was completely shut down at a stock level of 25 m, at 06:50 a.m. September 21. 1996. |
