［摘要］鍛造法蘭作為新型節(jié)點(diǎn)連接形式，在特高壓鋼管塔所占比重較大、造價(jià)較高。通過分析目前特高壓鋼管塔鍛造法蘭的應(yīng)用情況，提出了鍛造法蘭按強(qiáng)度級差設(shè)計(jì)的新方法。針對錫盟-勝利1 000千伏交流輸電線路鋼管塔的受力特點(diǎn)和鋼管庫規(guī)格，研究提出了Q345強(qiáng)度級差鍛造法蘭規(guī)格庫，完成了鋼管塔采用強(qiáng)度級差鍛造法蘭的經(jīng)濟(jì)性分析。研究表明：在特高壓鋼管塔設(shè)計(jì)中采用強(qiáng)度級差鍛造法蘭，最大程度地降低了鍛造法蘭的比重，能夠進(jìn)一步提高特高壓鋼管塔的經(jīng)濟(jì)性。

Abstract:As a new type of joint, the proportion and cost of forging flange in Ultra High Voltage(UHV) steel tubular tower are high. By analyzing the application of forging flange in UHV steel tubular towers, design method of strength graded forging flange was advanced. According to the bearing characteristic of steel tube tower and the steel tube specifications of Ximeng-Shengli 1 000kV Alternating Current(AC) transmission lines, serial specifications of Q345 strength graded forging flange were proposed and the economic analysis on strength graded forging flange used in steel tubular towers was carried out. Research shows that the application of strength graded forging flange in tower design can wholly reduce the proportion of forging flange, which can further improve the economy of UHV steel tubular tower.
Keywords:UHV AC; steel tubular tower; forging flange; strength graded; economy
