针对炉缸内衬破损的主要因素,将炼铁工艺设计和高炉长寿实践成果融入炉缸内衬设计,对炉缸内衬进行包含炼铁工艺设计、内衬性能设计、砌体结构设计等方面的体系设计为长寿型现代大型高炉奠定寿命技术基础至关重要。
A series of measures for realizing high blast temperature and long campaign have been taken in the design of ex- ternal combustion type hot air stove provided by Nippon Steel for 4350m~3 blast furnace newly built in Taiyuan Iron and Steel Co.
在新建的太钢4350m~3高炉新日铁外燃式热风炉的设计中,围绕高风温长寿命采取了一系列措施：蓄热室、燃烧室、混风室内墙体与拱顶的拱角相接处,采用迷宫式结构,防止独立砌体间窜风；在开孔部位采用组合砖,以提高这些关键部位的气密性和结构稳定性；蓄热室内采用带凹凸槽的小孔径七孔高效格砖,提高加热面积；采用分离型余热回收装置预热助燃空气和煤气等。
On the basis of analyzing the problem of unicasting QoS routing in Ad Hoc networks, a new distributed QoS routing algorithm in the Ad Hoc network— EBLLD (entropy-based long-life distributed QoS routing) algorithm, is proposed.
其核心思想是提出了衡量路径稳定性的新尺度——熵,并利用熵来选择长寿的路径,减少了重建路由(或路由修复)的次数,从而在 Ad Hoc 网的网络拓扑频繁变化的环境中尽可能地提供 QoS 保证。
