在修建鐵路所需的鋼鐵材料問(wèn)題上，張之洞在奏請(qǐng)修建盧漢鐵路的奏折中提出“造路之鐵可用華產(chǎn)”“購(gòu)買(mǎi)材料取之海外漏危太多，實(shí)為非計(jì)”。他主張修建鐵路必先自造鋼軌，因此他開(kāi)始一并籌辦漢陽(yáng)鐵廠。但*過(guò)了一年，因東北局勢(shì)緊張，清**將盧漢路款調(diào)撥給東北鐵路，盧漢鐵路暫?；I建，直到1895年甲午***后，清**才決定借債再次修筑盧漢鐵路。開(kāi)辦漢陽(yáng)鐵廠的目的本就是為盧漢鐵路提供鋼軌，修建盧漢鐵路是一波三折，漢陽(yáng)鐵廠的開(kāi)辦更是困難重重。1890年5月，張之洞在武昌成立湖北鐵政局，經(jīng)過(guò)親自勘察、反復(fù)研究和慎重考慮，張之洞決定將廠址建在漢陽(yáng)大別山下。1891年9月，漢陽(yáng)鐵廠破土動(dòng)工，張之洞對(duì)建廠事務(wù)“躬親細(xì)務(wù)，錙銖必較，急如星火，日夜操勞”?？朔酥刂乩щy后，漢陽(yáng)鐵廠于1893年年底完工，包括煉鐵廠、熟鐵廠、鋼軌廠、鋼材廠等10個(gè)分廠，蔚為壯觀，于1894年2月正式點(diǎn)火。</p><p>
