| In this paper, it has been introduced that the No 3 BF in Ansteel about structural configuration of crucible and hearth, the bosh of hyperpyrexia burthen area, the belly and the bellowing of the body with copper colling stave. The equipment and technics of the No. 3 BF can satisfy the request of high efficiency and longevity, for achieving that aim in deed, bringing the most economic bebifit. some produce datas of controlling gas current fair distribution and standardization operation have been analysed with the means of mathematical statistics, some right operating duties and operating parameters have been brought forward. Introduced how to judge the crucible operating state, to watch the heart erosion action and judge slag crust stability of copper cooling stave with temperature field. Introduced some manage BF longevity Projects with heat flow intensity and heat load datas, bringed forward some standards of BF managerial system and operating measure. In the end. the effects of computer technology in BF longevity manage have been summarized. |
