鞍(an)鋼(gang)生(sheng)產的(de)核一(yi)級設(she)備(bei)(bei)安(an)注(zhu)箱裝備(bei)(bei)用(yong)鋼(gang)SA-533Ty.B Cl.1在交付用(yong)戶后順(shun)利通過爆炸復合實驗，各項指標符合要求。這是鞍(an)鋼(gang)在核一(yi)級設(she)備(bei)(bei)安(an)注(zhu)箱用(yong)鋼(gang)領(ling)域(yu)的(de)首(shou)筆訂單，將(jiang)為核電(dian)機組堆芯撐起(qi)“保護(hu)傘(san)”。
核(he)反(fan)應(ying)堆(dui)堆(dui)芯(xin)因(yin)核(he)燃(ran)料裂變(bian)產生巨大(da)熱能(neng)，是一(yi)回路(lu)(lu)系統(tong)(tong)中(zhong)的(de)核(he)心(xin)。而安(an)注箱是一(yi)回路(lu)(lu)系統(tong)(tong)中(zhong)對核(he)反(fan)應(ying)堆(dui)堆(dui)芯(xin)起到保護作用的(de)重要(yao)應(ying)急安(an)全(quan)設備，當(dang)反(fan)應(ying)堆(dui)出現異常情況時，要(yao)求安(an)注箱能(neng)夠快(kuai)速將硼酸溶液注入(ru)堆(dui)芯(xin)防止燃(ran)料棒熔化(hua)，保證(zheng)核(he)電站的(de)核(he)心(xin)設備安(an)全(quan)。
近年(nian)來，經過不斷努力(li)，國內鋼企實現了(le)大部分三代核(he)電機(ji)組建設碳(tan)素結(jie)構用(yong)鋼和(he)低合金結(jie)構用(yong)鋼的(de)國產化(hua)，但作為核(he)一級設備的(de)安注(zhu)箱外部材(cai)料所需的(de)SA-533Ty.B Cl.1鋼板，卻(que)長期以(yi)來一直(zhi)依(yi)賴進口。
作(zuo)為國內重要(yao)的核(he)電用(yong)(yong)(yong)(yong)鋼(gang)(gang)生產企業，鞍鋼(gang)(gang)肩負著實現核(he)電用(yong)(yong)(yong)(yong)鋼(gang)(gang)關鍵材料國產化(hua)的重任。為滿足安注(zhu)箱裝備用(yong)(yong)(yong)(yong)鋼(gang)(gang)SA-533Ty.B Cl.1技術條件(jian)的苛刻要(yao)求，鞍鋼(gang)(gang)核(he)電用(yong)(yong)(yong)(yong)鋼(gang)(gang)項目組(zu)針對該(gai)鋼(gang)(gang)種的特性，從(cong)化(hua)學成(cheng)分(fen)到熱處理工藝均進行精心設計。在采用(yong)(yong)(yong)(yong)低(di)磷、低(di)硫(liu)成(cheng)分(fen)設計，嚴格控制各類非金(jin)屬夾(jia)雜物等級的基(ji)礎(chu)上，進一步(bu)優化(hua)軋制和調質處理工藝，成(cheng)功(gong)解決了鋼(gang)(gang)板內部質量、強韌性匹配以及(ji)鋼(gang)(gang)板頭尾(wei)性能(neng)差異等技術問題，一舉打破(po)國外(wai)技術壟斷，成(cheng)功(gong)研發出安注(zhu)箱裝備用(yong)(yong)(yong)(yong)鋼(gang)(gang)SA-533Ty.B Cl.1，并(bing)開始給徐大堡核(he)電機組(zu)供貨。
近(jin)年來，鞍鋼(gang)(gang)(gang)(gang)在核(he)(he)電(dian)(dian)機組關鍵設(she)(she)備用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)研(yan)制生產、下(xia)游(you)重(zhong)點核(he)(he)電(dian)(dian)項(xiang)目用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)市場開拓及(ji)產品(pin)標準(zhun)制訂的(de)(de)資質上(shang)取得的(de)(de)成績備受矚目，一躍成為(wei)當前國內(nei)核(he)(he)電(dian)(dian)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)市場上(shang)的(de)(de)“領(ling)跑者”。在國內(nei)率先具(ju)備了生產核(he)(he)反應(ying)堆(dui)安(an)全(quan)殼(ke)系(xi)(xi)(xi)列(lie)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)、核(he)(he)島(dao)主設(she)(she)備系(xi)(xi)(xi)列(lie)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)、核(he)(he)電(dian)(dian)常規(gui)島(dao)及(ji)配套系(xi)(xi)(xi)列(lie)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)等(deng)(deng)產品(pin)的(de)(de)能力和(he)資質，研(yan)發領(ling)域(yu)涵(han)蓋三代核(he)(he)電(dian)(dian)機組模塊用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)、鋼(gang)(gang)(gang)(gang)制安(an)全(quan)殼(ke)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)（MC級部件(jian)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)）、核(he)(he)反應(ying)堆(dui)壓力容器支撐(cheng)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)等(deng)(deng)。近(jin)一兩年，重(zhong)點開發核(he)(he)一級設(she)(she)備安(an)注箱用(yong)(yong)(yong)(yong)SA-533等(deng)(deng)鋼(gang)(gang)(gang)(gang)種。
