Icwecwe leNsimbi le-Q345b

Ukuqhubela phambili okuqhubekayo kwe-Q345b iteknoloji yepleyiti yensimbi ekunyibilikeni kunye nonyango lobushushu, kunye nophuhliso kunye nokuveliswa kweplate yentsimbi edibeneyo (i-cast) ngokuqengqeleka ifezekise iziphumo ezineziqhamo.Ubuninzi bentsimbi yentsimbi enokuthi ithathe indawo yokubumba (i-casting) ifikelele kwi-410mm, kwaye ubunzima beyunithi enkulu yi-38 toni.Thatha ukhokelo ekuguquleni nasekufezekiseni izixhobo ezinkulu zemveliso ye-ingot e-China, ukugcwalisa umsantsa weemveliso eziphezulu kwintsimi yasekhaya ebanzi kunye neplate enzima kunye nokuthatha indawo yokungenisa.Ubukhulu obukhulu be-Z35-grade plate yensimbi, ithatha inzuzo yeteknoloji kunye nezixhobo, i-Z-direction plate yensimbi enobukhulu obuyi-200mm-300mm.Ipleyiti yentsimbi ye-Z35 enobukhulu obukhulu luhlobo lwentsimbi etyebileyo eyongezelelekileyo esetyenziswa phantsi kweemeko ezithile zokusingqongileyo, njengeringi yesihlalo se-turbine, i-vane yesikhokelo kunye nezinye iindawo eziphambili zeseti yejenereyitha, kunye nokhuseleko, ukuthembeka kunye nobomi obude benkonzo. ziphezulu kakhulu.Ukuphuhlisa i-200mm-300mm ipleyiti yensimbi eninzi kunye nobukhulu obukhulu bezinga le-Z35, kuyimfuneko ukuqinisekisa ukuba ukusebenza kwe-anti-lamellar yokukrazula kufinyelela kwibakala le-Z35.Lo ngumbuzo onzima kakhulu "wokhuphiswano lwe-Olimpiki" oluqatshelwe lishishini le-metallurgical.Kuyimfuneko ukoyisa ubunzima bobugcisa obufana nolawulo lokuqina lwee-ingots ezinkulu zentsimbi, unyango lobushushu lweepleyiti ezinkulu zentsimbi, ubushushu obuphantsi befuthe lokuqina kweepleyiti ezinkulu zentsimbi kunye nokumelana nokukrazula kwe-laminar.Imigaqo: Enye kukuqinisekisa ukuba ineweldability elungileyo;enye kukuqinisekisa ukusebenza kwicala lobunzima;eyesithathu kukuqinisekisa ukuba inefuthe elaneleyo koovimba bokuqina kunye nobushushu obuphantsi be-ductile brittle transition kwiqondo lobushushu bokusebenzisa;okwesine kukuphucula ukhuseleko lwesakhiwo.Sebenzisa ubugcisa obucokisekileyo ukuphuhlisa umgangatho ophezulu weemveliso zentsimbi ze-Z ezinobunzima obukhulu bombane wamanzi.Kuwo onke amakhonkco enkqubo anjengokunyibilikisa, ukuqengqeleka, unyango lobushushu, yonke le nkqubo ilandelwa, kunye nemitha yobushushu obuphezulu obungama-500 degrees Celsius iyanyanyezelwa, kunye ne-200mm eshinyeneyo S355J0-Z35 kunye ne-270mm engqindilili ye-A516Gr70-Z35 iipleyiti zentsimbi ziye zaphuhliswa ngokulandelelanayo. ngokusekelwe kwimigangatho ye-EN10025 kunye noyilo lombane wamanzi Ngokweemfuno zobugcisa zeziko, i-Z35 ipleyiti yensimbi enobunzima be-300mm ekugqibeleni yaphuhliswa ngempumelelo.Emva kokuhlolwa, inokuhlangabezana ngokupheleleyo neemfuno zemigangatho yobugcisa efanelekileyo kwaye ifikelele kwinqanaba langempela.Uphuhliso lwayo oluyimpumelelo luqhubele phambili kakhulu kwinqanaba lophuhliso lombane welizwe lam obunzima obukhulu be-Z-steel technology.Uphando oluyimpumelelo kunye nophuhliso lwentsimbi yentsimbi eyi-300mm engqindilili ye-Z35 iyitshintshile imeko yokuba ishishini lombane welizwe lam kudala lixhomekeke ekuthengisweni kwentsimbi eshinyeneyo engu-Z-direction enkulu, ebaluleke kakhulu kusetyenziso lwasekhaya lwezixhobo ezinkulu.I-300mm-thick ye-Z35 ipleyiti yensimbi i-node entsha yobukhulu obukhulu be-Z-direction yensimbi yokungena kwishishini lombane wamanzi.Oku kuya kukhuthaza impumelelo eqhubekayo ekuphuhliseni ubukhulu obukhulu bentsimbi ye-Z-direction for hydropower.Okubaluleke ngakumbi, ipleyiti yentsimbi eyi-300mm engqindilili ye-Z35 ayinakusetyenziswa kuphela kwishishini lombane wamanzi, kodwa nasekuveliseni ezinye izixhobo ezingundoqo ezinkulu, ezinethemba elibanzi.
