4. Ipuleti lensimbi elibilayo kanye nepuleti lensimbi elibulewe: 1. Ipuleti lensimbi elibilayo ipuleti lensimbi eligoqiwe elishisayo elenziwe ngensimbi evamile ye-carbon structural abilayo.Insimbi ebilayo iwuhlobo lwensimbi ene-deoxidation engaphelele.Inani elithile kuphela le-deoxidizer ebuthakathaka lisetshenziselwa ukukhipha insimbi encibilikisiwe.Okuqukethwe komoyampilo kwensimbi encibilikisiwe kuphezulu uma kuqhathaniswa., yingakho igama lensimbi ebilayo.Insimbi ebilayo inokuqukethwe kwekhabhoni ephansi, futhi njengoba i-ferrosilicon ingakhishwa yi-deoxidized, okuqukethwe kwe-silicon ensimbi nakho kuphansi (Si<0.07%).Isendlalelo sangaphandle sensimbi ebilisa icwecwe ngaphansi kwesimo sokunyakaziswa okunamandla kwensimbi encibilikisiwe okubangelwa ukubilisa, ngakho-ke ungqimba olungaphezulu luhlanzekile futhi luminyene, lunekhwalithi enhle, ipulasitiki enhle nokusebenza kokubhoboza, azikho izimbobo ezinkulu zokuncibilika ezigxilile, iziphetho ezinqunyiwe.kancane, isivuno siphezulu, futhi inqubo yokukhiqiza insimbi ebilisa ilula, ukusetshenziswa kwe-ferroalloy kuncane, futhi izindleko zensimbi ziphansi.Ipuleti lensimbi elibilayo lisetshenziswa kabanzi ekwenzeni izingxenye ezihlukahlukene zokugxiviza, izakhiwo zokwakha nezobunjiniyela kanye nezinye izingxenye zesakhiwo somshini ezingabalulekile kangako.Kodwa-ke, kukhona ukungcola okuningi enkabeni yensimbi ebilayo, ukuhlukaniswa kubi kakhulu, isakhiwo asinamandla, futhi izakhiwo zemishini azifani.Ngesikhathi esifanayo, ngenxa yokuqukethwe kwegesi ephezulu ensimbi, ukuqina kuphansi, i-brittleness ebandayo kanye nokuzwela ukuguga kuphezulu, nokusebenza kwe-welding nakho kubi.Ngakho-ke, ipuleti yensimbi ebilisayo ayifanele ukwakhiwa kwezakhiwo ezishiselwe nezinye izakhiwo ezibalulekile ezibhekene nemithwalo yethonya futhi zisebenze ngaphansi kwezimo eziphansi zokushisa.2. Ipuleti lensimbi elibulewe ipuleti lensimbi elenziwe ngensimbi evamile ye-carbon structural ebulawe insimbi ngokugingqika okushisayo.Insimbi ebulewe iyinsimbi e-deoxidized ngokuphelele.Insimbi encibilikisiwe ikhishwe ngokuphelele kwi-ferromanganese, i-ferrosilicon ne-aluminium ngaphambi kokuthululwa.Okuqukethwe kwe-oxygen yensimbi encibilikisiwe kuphansi (imvamisa i-0.002-0.003%), futhi insimbi encibilikisiwe izolile ngokuqhathaniswa nesikhunta se-ingot.Ayikho into ebilayo eyenzekayo, yingakho igama lensimbi ebulewe.Ngaphansi kwezimo ezijwayelekile zokusebenza, awekho ama-bubbles ensimbi ebulewe, futhi isakhiwo sifana futhi siminyene;ngenxa yokuqukethwe kwe-oksijini ephansi, insimbi ine-oxide encane ehlanganisiwe, ukuhlanzeka okuphezulu, kanye ne-brittleness ebandayo ephansi kanye nokuthambekela kokuguga;ngesikhathi esifanayo, insimbi ebulewe inokuhlukaniswa okuncane, Ukusebenza kufana nokufana futhi izinga liphezulu.Ububi bensimbi ebulewe ukuthi igxilise imigodi enciphayo, isivuno esiphansi kanye nenani eliphezulu.Ngakho-ke, insimbi ebulewe isetshenziselwa ikakhulukazi izingxenye ezithintekayo emazingeni okushisa aphansi, izakhiwo ezishiselwe nezinye izingxenye ezidinga amandla aphezulu.Amapuleti ensimbi aphansi abulawa insimbi kanye namapuleti ensimbi abulawelwe kancane.Ngenxa yamandla ayo aphezulu nokusebenza okuphezulu, ingakwazi ukonga insimbi eningi futhi inciphise isisindo sesakhiwo, futhi ukusetshenziswa kwayo sekuye kwanda kakhulu.5. Ipuleti lensimbi yesakhiwo sekhabhoni yekhwalithi ephezulu: Insimbi yekhwalithi ephezulu ye-carbon structural iyinsimbi ye-carbon enokuqukethwe kwekhabhoni engaphansi kuka-0.8%.Le nsimbi iqukethe i-sulphur encane, i-phosphorus kanye ne-non-metallic inclusions kunensimbi ye-carbon structural, futhi inezici ezinhle kakhulu zemishini..Insimbi yesakhiwo sekhabhoni esezingeni eliphezulu ingahlukaniswa izigaba ezintathu ngokuya kokuqukethwe kwekhabhoni: insimbi ye-carbon ephansi (C≤0.25%), insimbi ye-carbon steel (C ingu-0.25-0.6%) kanye ne-carbon steel ephezulu (C>0.6%).Insimbi yesakhiwo sekhabhoni yekhwalithi ephezulu ihlukaniswe ngamaqembu amabili ngokuya kokuqukethwe kwe-manganese okuhlukile: okuqukethwe kwe-manganese evamile (i-manganese 0.25% -0.8%) kanye nokuqukethwe kwe-manganese ephakeme (i-manganese 0.70% -1.20%), lokhu okulandelayo kunezinto ezingcono zemishini.ukusebenza kanye nokusebenza.1. Ikhwalithi ephezulu ye-carbon structural steel Amashidi namapheshana ensimbi yekhwalithi ephezulu ye-carbon structural steel hot-rolled asetshenziswa embonini yezimoto, yezokundiza neminye imikhakha.
Amabanga ensimbi yawo ayinsimbi ebilayo: 08F, 10F, 15F;insimbi ebulewe: 08, 08AL, 10, 15, 20, 25, 30, 35, 40, 45, 50. 25 nangaphansi kukhona amapuleti ensimbi anekhabhoni ephansi, 30 futhi Ngaphezu kuka-30 ipuleti lensimbi ye-carbon steel.2. Insimbi yekhwalithi ephezulu yensimbi eshisayo egoqelwe ngamapuleti ensimbi agqinsile namapheshana ensimbi abanzi Amapuleti ensimbi awugqinsi aginqike ngekhabhoni esezingeni eliphakeme kanye nemicu yensimbi ebanzi ezingxenyeni ezihlukahlukene zesakhiwo.
Amamaki ayo ensimbi ayinsimbi ephansi ye-carbon ehlanganisa: 05F, 08F, 08, 10F, 10, 15F, 15, 20F, 20, 25, 20Mn, 25Mn, njll.;medium carbon steel kuhlanganisa: 30, 35, 40, 45, 50, 55, 60, 30Mn, 40Mn, 50Mn, 60Mn, njll;
