由(you)德(de)國(guo)維替(W&T )公司牽頭，聯(lian)合中國(guo)多家(jia)相關單位及院校共同攻堅的(de)濕法冶煉裝(zhuang)備(bei)——閃蒸汽(qi)閥(fa)與耐磨抗腐蝕球閥(fa)研發項目(mu)取得圓滿成功！

此次突破(po)三大技(ji)術(shu)里程碑：

1、打(da)破技術壟斷：項目團隊在(zai)苛(ke)刻工況下(xia)的材料(liao)耐蝕性、閃蒸流體控制等(deng)12項關鍵技術瓶頸，產(chan)品(pin)經俄方嚴格(ge)測(ce)試完(wan)全(quan)達(da)標，標志著中國在(zai)特種閥門領域(yu)實現自主可控；

2、產(chan)學研(yan)協同創新：通過產(chan)業鏈上下游聯(lian)合研(yan)發，創新采用(yong)新型碳化硅基(ji)復合材料、多級減壓(ya)閃(shan)蒸(zheng)結(jie)構、智能表面強化技術等(deng)實現使用(yong)壽命(ming)更長(chang)；

3、服務中國'一(yi)(yi)帶一(yi)(yi)路'建(jian)設

首批交付俄(e)羅斯(si)某大(da)型冶煉廠的(de)閥(fa)(fa)門(men)組(zu)，在(zai) 210℃的(de)稀硫酸工(gong)況下穩定運(yun)行超 2880 小時，在(zai)國(guo)際市場獲(huo)得相關客戶高度認(ren)可(ke)。此(ci)次突破不僅填補了(le)中國(guo)技術空白(bai)，更帶動了(le)特種材料、精(jing)密加工(gong)等配套產業鏈升(sheng)級(ji)，工(gong)業閥(fa)(fa)門(men)，為(wei)中國(guo)智造點(dian)贊！
