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. Ubukhulu obukhulu be-Z35 ipleyiti yensimbi luhlobo lwentsimbi yentsimbi eyongezelelweyo esetyenziswa phantsi kweemeko ezithile zokusingqongileyo, ezifana neseyili yesihlalo se-turbine, i-vane yesikhokelo kunye nezinye iindawo eziphambili zeseti yejeneretha, kwaye ukhuseleko lwayo, ukuthembeka kunye nobomi obude benkonzo buphezulu 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 "umbuzo wokhuphiswano lwe-Olimpiki" ovunywe lishishini lesinyithi. 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 anje ngokunyibilikisa, 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 eshinyeneyo ye-A516Gr70-Z35 yeepleyiti zentsimbi ziye zaphuhliswa ngokulandelelana ngokusekwe kwi-EN10025 yoyilo lwamandla kunye noyilo lwe-hydropower. Ipleyiti yentsimbi ye-Z35 enobunzima obuyi-300mm yaphuhliswa ngempumelelo ekugqibeleni. 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-engqingqwa 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.
