4. Ipuleti lensimbi elibilayo kanye nepuleti lensimbi elibulewe:

1. Ipuleti lensimbi elibilayo ipuleti lensimbi eligoqiwe elishisayo lisuka kunsimbi ebilayo ye-carbon structural evamile.Insimbi ebilayo iwuhlobo lwensimbi ene-deoxidation engaphelele.Inani elithile kuphela le-deoxidizer ebuthakathaka lisetshenziselwa ukukhipha insimbi encibilikisiwe.Okuqukethwe komoyampilo kwensimbi encibilikisiwe kuphezulu uma kuqhathaniswa.Lapho insimbi encibilikisiwe ijovwa ekubunjweni kwe-ingot, ikhabhoni nomoya-mpilo kusabela ukukhiqiza inani elikhulu legesi, okwenza insimbi encibilikisiwe ibile., Insimbi ebilayo yathola igama layo kulokhu.Insimbi ene-rimmed inokuqukethwe kwekhabhoni ephansi, futhi ngenxa yokuthi ayisebenzisi i-ferrosilicon ukwenza i-deoxidation, okuqukethwe kwe-silicon ensimbi nakho kuphansi (Si<0.07%).Ungqimba lwangaphandle lwensimbi ebilayo lucwebezeliswa ngaphansi kwezimo zokuyaluza okunamandla kwensimbi encibilikisiwe okubangelwa ukubilisa, ngakho ungqimba olungaphezulu luhlanzekile futhi luminyene, lunekhwalithi enhle, ipulasitiki enhle kanye nezakhiwo zokunyathela, azikho izimbobo ezinkulu zokushwabana ezigxilile, nekhanda elisikayo. Izinga lokukhiqizwa kwensimbi ene-rimmed lilula, ukusetshenziswa kwe-ferroalloy kuncane, futhi izindleko zensimbi ziphansi.Amapuleti ensimbi abilayo asetshenziswa kakhulu ekwenzeni izingxenye ezihlukahlukene zokugxiviza, izakhiwo zokwakha nezobunjiniyela kanye nezinye izingxenye zesakhiwo somshini ezingabalulekile kangako.Kodwa-ke, kukhona ukungcola okuningi emnyombweni wensimbi ebilayo, ukuhlukaniswa kubi kakhulu, isakhiwo asiminyene, futhi izakhiwo zemishini azilingani.Ngesikhathi esifanayo, ngenxa yokuqukethwe kwegesi ephezulu ensimbi, ukuqina kuphansi, ukuqina okubandayo nokuzwela ukuguga kukhulu ngokuqhathaniswa, kanye nokusebenza kokushisela nakho kubi.Ngakho-ke, amapuleti ensimbi abilayo awafanele ukukhiqiza izakhiwo ezishiselwe nezinye izakhiwo ezibalulekile ezithwala imithwalo 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, yingakho igama lensimbi ebulewe.Ngaphansi kwezimo ezijwayelekile zokusebenza, awekho ama-bubbles ensimbi ebulewe, futhi isakhiwo sifana futhi sihlangene;ngenxa yokuqukethwe kwe-oxygen ephansi, insimbi iqukethe izinto ezincane ze-oxide, ukuhlanzeka okuphezulu, i-brittleness ebandayo ephansi kanye nokuthambekela kokuguga;ngesikhathi esifanayo, ukuhlukaniswa kwensimbi ebulewe kuncane, Ukusebenza kufana nomfaniswano futhi izinga liphezulu.Ukungalungi kwensimbi ebulewe ukuncipha okugxilile, isivuno esiphansi kanye nenani eliphezulu.Ngakho-ke, insimbi ebulewe isetshenziselwa ikakhulukazi izingxenye ezimelana nomthelela emazingeni okushisa aphansi, izakhiwo ezishiselwe, nezinye izakhi ezidinga amandla aphezulu.

Amapuleti ensimbi ane-alloy ephansi womabili amapuleti ensimbi abulewe nabulawa kancane.Ngenxa yamandla ayo aphezulu nokusebenza okuphakeme, ingasindisa insimbi eningi futhi inciphise isisindo sesakhiwo, ukusetshenziswa kwayo sekuye kwanda kakhulu.

5. Ipuleti lensimbi yesakhiwo sekhabhoni ephezulu:

Insimbi yekhwalithi ephezulu ye-carbon structural steel iyinsimbi ye-carbon ene-carbon content engaphansi kuka-0.8%.Le nsimbi iqukethe i-sulphur encane, i-phosphorus kanye ne-non-metallic inclusions kunensimbi ye-carbon structural, futhi inezici ezingcono zemishini.

Insimbi yesakhiwo sekhabhoni esezingeni eliphezulu ingahlukaniswa izigaba ezintathu ngokuya kokuqukethwe kwekhabhoni ehlukene: insimbi enekhabhoni ephansi (C≤0.25%), insimbi ye-carbon ephakathi (C ingu-0.25-0.6%) kanye nensimbi enekhabhoni ephezulu (C>0.6) %).

Ngokusho kokuqukethwe kwe-manganese ehlukene, insimbi yekhwalithi ephezulu ye-carbon structural ingahlukaniswa ngamaqembu amabili: okuqukethwe kwe-manganese evamile (okuqukethwe kwe-manganese 0.25% -0.8%) kanye nokuqukethwe kwe-manganese ephakeme (okuqukethwe kwe-manganese 0.70% -1.20%).Eyakamuva inomakhenikha abangcono.Ukusebenza nokucubungula ukusebenza.

1. Ishidi eliphezulu lensimbi yesakhiwo se-carbon structural steel hot-rolled strip kanye nomugqa wensimbi Ishidi lensimbi elincanyana le-carbon structural eligoqelwe elicolisekile elicwengekile kanye nomugqa wensimbi kusetshenziswa embonini yezimoto, yezokundiza kanye neminye imikhakha.Amabanga ayo ensimbi ayinsimbi enamasondo: 08F, 10F, 15F;insimbi ebulewe: 08, 08AL, 10, 15, 20, 25, 30, 35, 40, 45, 50. Amapuleti ensimbi ekhabhoni aphansi angaphansi kuka-25 no-25, 30 nangaphezulu kuka-30 yi-medium carbon steel plate.

2. Insimbi yekhwalithi ephezulu ye-carbon structural steel hot-rolled steel stall kanye namapheshana ensimbi abanzi Amapuleti ensimbi awugqinsi wekhwalithi ephezulu yekhabhoni eshisayo aginqike namapheshana ensimbi abanzi asetshenziswa ezingxenyeni ezihlukahlukene zesakhiwo.Amamaki ayo ensimbi angama-carbon steels aphansi ahlanganisa: 05F, 08F, 08, 10F, 10, 15F, 15, 20F, 20, 25, 20Mn, 25Mn, njll.;medium carbon steels zihlanganisa: 30, 35, 40, 45, 50, 55, 60, 30Mn, 40Mn, 50Mn, 60Mn, njll;high carbon steel ihlanganisa: 65, 70, 65Mn, njll.

6. Ipuleti lensimbi lesakhiwo esikhethekile:
