漢陽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，漢陽鐵廠的開辦更是困難重重。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大別山下。1891年9月，漢陽鐵廠破土動(dòng)工，張之洞對建廠事務(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。但是，鐵廠剛開始投產(chǎn)就面臨一個(gè)**大的實(shí)際問題——資金不足。清**所撥費(fèi)用已全部用完，而投產(chǎn)所需資金至少100萬兩白銀。張之洞奏請朝廷，提出設(shè)備“分量、分撥”投產(chǎn)，以解決資金周轉(zhuǎn)問題，減少開工費(fèi)。他還建議朝廷將建造湖北***炮廠等工廠的資金“撥借”過來。緊接著，有一個(gè)大難題接踵而來，由于缺乏經(jīng)驗(yàn)，前期技術(shù)準(zhǔn)備不充分，所用的原材料大冶鐵礦砂和煉鋼爐不匹配，無法提取大冶鐵礦砂中所含高濃度的磷，造成試軋出的鋼軌質(zhì)脆易裂，不能普遍使用，鐵廠經(jīng)營陷入了困境。1896年，漢陽鐵廠改為官督商辦，張之洞舉薦盛宣懷接手，之后又對冶煉設(shè)備進(jìn)行了重整改造，鋼鐵質(zhì)量轉(zhuǎn)佳，經(jīng)營銷售一度頗有生機(jī)。烏魯木齊的重軌低價(jià)資料</p><p
