本報訊(xun)近日，寶鋼股(gu)份(fen)厚(hou)(hou)板(ban)事業部5m厚(hou)(hou)板(ban)產線交(jiao)付完(wan)成了“華龍(long)一(yi)號”陸豐核(he)電(dian)(dian)(dian)項目(mu)(mu)安注(zhu)箱關(guan)鍵(jian)(jian)設備用全部350噸18MND5鋼板(ban)。這是繼(ji)2018年(nian)寶鋼股(gu)份(fen)助力“華龍(long)一(yi)號”惠州核(he)電(dian)(dian)(dian)項目(mu)(mu)關(guan)鍵(jian)(jian)設備首次實現(xian)“中國(guo)(guo)造(zao)”之后，再次與用戶緊密合作(zuo)，進(jin)一(yi)步鞏固(gu)關(guan)鍵(jian)(jian)材料(liao)的(de)國(guo)(guo)產化力作(zuo)，為我國(guo)(guo)核(he)電(dian)(dian)(dian)走向世(shi)界的(de)“國(guo)(guo)家名片”貢獻寶鋼厚(hou)(hou)板(ban)力量。

2021年6月，寶(bao)鋼(gang)股份(fen)承(cheng)接了“華龍一(yi)號”陸豐核電站(zhan)全部機組(zu)安(an)注(zhu)箱用封頭和(he)筒體用18MND5鋼(gang)板(ban)(ban)的生(sheng)產任(ren)務。該安(an)注(zhu)箱封頭用板(ban)(ban)屬特(te)厚(hou)的超(chao)寬板(ban)(ban)，筒體板(ban)(ban)屬大單重、特(te)厚(hou)、超(chao)寬、超(chao)長板(ban)(ban)，成品(pin)單重達(da)33.1噸。該批鋼(gang)板(ban)(ban)成品(pin)檢測項(xiang)目繁(fan)多、性(xing)能(neng)(neng)指標(biao)要(yao)求高(gao)，要(yao)同時兼顧(gu)交貨態(tai)和(he)模(mo)擬焊后熱處理態(tai)下室溫(wen)和(he)高(gao)溫(wen)下多項(xiang)性(xing)能(neng)(neng)指標(biao)，工(gong)(gong)藝窗口極窄(zhai)。為了實現鋼(gang)板(ban)(ban)成分、性(xing)能(neng)(neng)全部達(da)標(biao)，研發(fa)團隊設計了寶(bao)山基地冶煉連鑄坯、生(sheng)態(tai)圈伙伴電渣重熔(rong)鋼(gang)錠、寶(bao)山基地5m厚(hou)板(ban)(ban)軋制(zhi)及(ji)調(diao)質(zhi)熱處理的生(sheng)產工(gong)(gong)藝，并對各工(gong)(gong)序生(sheng)產過(guo)程提出(chu)嚴(yan)格的質(zhi)量管控要(yao)求。

盡(jin)管(guan)整個生產(chan)過程持(chi)續時間長，關鍵工序環節(jie)控(kong)制(zhi)(zhi)點多，憑借(jie)多年(nian)積(ji)累的核電用(yong)鋼制(zhi)(zhi)造(zao)、管(guan)理和質量(liang)控(kong)制(zhi)(zhi)能力(li)，厚板(ban)(ban)(ban)核電產(chan)銷研團隊克服(fu)困難(nan)，用(yong)了8個多月的時間就完(wan)成(cheng)了全(quan)部(bu)1張封(feng)頭評定板(ban)(ban)(ban)、6張封(feng)頭板(ban)(ban)(ban)、12張筒體板(ban)(ban)(ban)的生產(chan)。在(zai)用(yong)戶(hu)和業主全(quan)程監造(zao)下，19張鋼板(ban)(ban)(ban)的各項(xiang)性能、尺寸、表面質量(liang)及探傷(shang)等全(quan)部(bu)一次驗收合格，為陸豐核電項(xiang)目(mu)安注(zhu)箱按節(jie)點推進(jin)制(zhi)(zhi)造(zao)贏得了時間。目(mu)前，封(feng)頭鋼板(ban)(ban)(ban)已順利(li)壓制(zhi)(zhi)成(cheng)封(feng)頭。

下(xia)一(yi)步，寶(bao)鋼股(gu)份(fen)將與相關方精誠協同(tong)，尋求更(geng)加(jia)高效簡(jian)潔(jie)、制造(zao)(zao)周期更(geng)加(jia)短的“華龍一(yi)號”核(he)電安注箱快速制造(zao)(zao)的整(zheng)體解決(jue)方案(an)，為中國核(he)電事(shi)業繼續貢獻寶(bao)鋼厚板力量。
