Esimisweni sezimboni sanamuhla, ama-coil ensimbi ashiswayo ayizinto eziyisisekelo, futhi ukuhlukahluka kwawo kwamamodeli kanye nokwehluka kokusebenza kuthinta ngqo indlela yokuthuthukiswa kwezimboni ezingezansi. Amamodeli ahlukene ama-coil ensimbi ashiswayo adlala indima engenakuphikwa emikhakheni yokwakha, izimoto, amandla, njll. ngokwakheka kwawo okuyingqayizivele kwamakhemikhali kanye nezakhiwo zemishini. Okulandelayo kuzogxila ekuhlaziyeni amamodeli e-coil ensimbi ashiswayo anesidingo esikhulu semakethe kanye nokwehluka kwawo okuyinhloko.
Amandla Ayisisekelo Ayinhloko: Q235B kanye ne-SS400
I-Q235B iyinsimbi yesakhiwo esetshenziswa kakhulu eShayina, enokuqukethwe kwekhabhoni okungaba ngu-0.12%-0.20%, futhi inezakhiwo ezinhle ze-plasticity kanye nokushisela. Amandla ayo okukhiqiza angama-≥235MPa futhi isetshenziswa kabanzi ezakhiweni zozimele, izisekelo zamabhuloho kanye nezingxenye ezijwayelekile zemishini. Embonini yokwakha, izinsimbi ze-I, izinsimbi zesiteshi kanye nezinye izinsimbi ezenziwe ngamakhoyili ensimbi ashiswayo e-Q235B zingaphezu kuka-60%, zisekela uhlaka lwengqalasizinda yasemadolobheni.
I-SS400 iyinsimbi yesakhiwo sekhabhoni esetshenziswa emhlabeni wonke enamandla afana ne-Q235B, kodwa ilawulwa ngokuqinile ukungcola kwe-sulfur ne-phosphorus kanye nekhwalithi engcono ebusweni. Emkhakheni wokwakha imikhumbi, ama-SS400 coils ashiswayo avame ukusetshenziselwa izingxenye zesakhiwo se-shell. Ukumelana kwayo nokugqwala kwamanzi olwandle kungcono kunensimbi yekhabhoni evamile, okuqinisekisa ukuphepha kohambo lolwandle.
Abameleli abanamandla aphezulu: Q345B kanye ne-Q960
I-Q345B iyinsimbi enamandla aphezulu ene-alloy ephansi ene-manganese engu-1.0%-1.6%, futhi amandla okukhiqiza angaphezu kuka-345MPa. Uma kuqhathaniswa ne-Q235B, amandla ayo anda cishe ngo-50%, kuyilapho igcina ukushibilika okuhle. Kubunjiniyela bebhuloho, ama-box girders enziwe ngama-coil ensimbi ashibilikayo e-Q345B anganciphisa isisindo ngo-20%, okunciphisa kakhulu izindleko zobunjiniyela. Ngo-2023, ukwakhiwa kwebhuloho lasekhaya kuzodla amathani angaphezu kwezigidi ezingu-12 ama-coil ashibilikayo e-Q345B, okwenza u-45% womkhiqizo wonke walolu hlobo.
Njengommeleli ojwayelekile wensimbi enamandla kakhulu, i-Q960 ifinyelela amandla okukhiqiza angu-≥960MPa ngobuchwepheshe be-microalloying (ukwengeza i-vanadium, i-titanium nezinye izakhi) kanye nezinqubo zokupholisa ezilawulwayo nezilawulwayo. Emkhakheni wemishini yobunjiniyela, ubukhulu bengalo ye-crane eyenziwe nge-Q960 hot-rolled coil bungancishiswa bube ngaphansi kuka-6mm, futhi amandla okuthwala umthwalo anda izikhathi ezi-3, okukhuthaza ukuthuthukiswa okulula kwemishini efana nemishini yokumba kanye ne-crane.
Isilinganiso Esikhethekile: I-SPHC ne-SAPH340
I-SPHC iwumkhiqizo osezingeni eliphezulu phakathi kwezinsimbi ezigoqeka kancane ezinekhabhoni eshisayo. Ngokwenza inqubo yokugoqa ibe ngcono ukuze kulawulwe usayizi wezinhlamvu, ukunwebeka kufinyelela ngaphezu kuka-30%. Embonini yemishini yasekhaya, amakhoyili agoqeka kancane e-SPHC asetshenziselwa ukukhiqiza izindlu ze-compressor zesiqandisi. Ukusebenza kwayo okujulile kokudweba kuqinisekisa ukuthi izinga elifanelekile lokwakheka kwendawo egoqekile eyinkimbinkimbi lidlula u-98%. Ngo-2024, ukusetshenziswa kwamakhoyili agoqeka kancane e-SPHC ensimini yemishini yasekhaya kuzokhula ngo-15% unyaka nonyaka kuya kumathani ayizigidi ezingu-3.2.
Njengensimbi yesakhiwo sezimoto, i-SAPH340 ifinyelela ibhalansi phakathi kwamandla nokuqina ngokungeza i-carbon engu-0.15%-0.25% kanye ne-trace boron. Ekukhiqizweni kwamafreyimu ebhethri lezimoto ezintsha zamandla, amakhoyili ashiswayo e-SAPH340 angamelana nemithwalo enamandla engaphezu kwe-500MPa futhi ahlangabezane nezidingo zezinqubo zokushisela amabala. Ngo-2023, isilinganiso samakhoyili ashiswayo alolu hlobo asetshenziswa ezimotweni zamandla ezintsha zasekhaya sifinyelele ku-70% wezingxenye zesakhiwo sebhethri.
| Imodeli | Amandla Okukhiqiza (i-MPa) | Ukwelulwa (%) | Izimo Ezijwayelekile Zokusebenza |
| Q235B | ≥235 | ≥26 | Izakhiwo zezakhiwo, imishini ejwayelekile |
| Q345B | ≥345 | ≥21 | Amabhuloho, imikhumbi yokucindezela |
| I-SPHC | ≥275 | ≥30 | Izinto zikagesi zasekhaya, izingxenye zezimoto |
| I-Q960 | ≥960 | ≥12 | Imishini yobunjiniyela, imishini esezingeni eliphezulu |
Uma ufuna ukwazi okwengeziwe ngensimbi, sicela uqhubeke nokulalela noma usithinte.
