Kuyini insimbi?
Insimbi iyi-alloy ye-iron kanye nento eyinhloko (eyinhloko) ye-aloying element iyikhabhoni. Kodwa-ke, kunokunye okuhlukile kule ncazelo efana ne-InterSteritial-Free (uma) ama-Steel futhi uhlobo lwensimbi engama-409 Ferritic Ferrititic, lapho kubhekwa khona ikhabhoni njengokungcola.
Yini i-alloy?
Lapho izinto ezahlukene zixutshwe ngamanani amancane endaweni eyisisekelo, umkhiqizo ophumayo ubizwa ngokuthi yi-alloy yento eyisisekelo. Ngakho-ke insimbi iyinhlangano ye-iron ngoba i-iron yinto eyisisekelo (isakhi esiyinhloko) ngensimbi kanye nento eyinhloko ye-alloying yi-carbon. Ezinye izinto ezinjenge-manganese, i-silicon, i-nickel, i-chromium, i-molybdenum, i-aluminium, i-niobium, i-aluminium, njll.
I-Jindalai (Shandong) yensimbi Co, Ltd. Isiprofetho esikhethekile kanye nomhlinzeki oholayo wemigoqo yensimbi engenazinsimbi / amapayipi / amakholi / amakhethini. Thumela uphenyo lwakho futhi sizokujabulela ukukubona kahle.
Yiziphi izinhlobo ezahlukene zensimbi?
Ngokusekelwe kwizingoma zamakhemikhali, insimbi ingahlukaniswa ngezinhlobo ezine (04) eziyisisekelo eziyisisekelo:
● I-Carbon Insimbi
● insimbi engagqwali
● insimbi ye-alloy
● Ithuluzi Insimbi
1. I-Carbon Steel:
I-Carbon Steel iyinsimbi esetshenziswa kakhulu ezimbonini nama-akhawunti angaphezu kwama-90% okukhiqizwa kwensimbi okuphelele. Ngokusekelwe kokuqukethwe kwekhabhoni, ama-carbon steel ahlukaniswe futhi abe ngamaqembu amathathu.
● i-carbon yensimbi ephansi / insimbi emnene
● Insimbi Ephakathi Ikhabhoni
● Insimbi ephakeme yekhabhoni
Okuqukethwe kwekhabhoni kunikezwa etafuleni elingezansi:
| Cha. | Uhlobo lwensimbi yekhabhoni | Amaphesenti ekhabhoni |
| 1 | I-carbon yensimbi ephansi / insimbi emnene | Kufika ku-0.25% |
| 2 | I-Medium Carbon Steel | 0.25% kuya ku-0.60% |
| 3 | Insimbi ephezulu yekhabhoni | 0.60% kuya ku-1.5% |
2. Insimbi Engagqwali:
Insimbi engenasici iyinsimbi ye-alloy equkethe i-chromium engu-10,5% (ubuncane). I-Stainless Steel Ekhombisa Ukumelana Nama-Corrosion Ukumelana, Ngenxa yokwakheka kwesendlalelo esincanyana se-CR2O3 ebusweni bayo. Le ungqimba yaziwa nangokuthi ungqimba olungenasisekelo. Ukukhulisa inani le-chromium kuzokwengeza ukumelana nokugqwala kwezinto ezibonakalayo. Ngaphezu kwe-chromium, i-nickel ne-molybdenum nayo ingezwe ukuletha izakhiwo ezifiselekayo (noma ezithuthukisiwe). Insimbi engenasici futhi iqukethe amanani ahlukahlukene ekhabhoni, i-silicon, kanye nabangane.
Ama-steanless ahlukaniswa futhi anjengokuthi;
1. I-Ferritic Steel engenasici
2. Ama-Martensitic Steel Agnainless
3. I-Autenitic Steel engenasici
4
I-5
● I-Ferritic Insimbi Engagqwali: Ama-Ferritic Steel aqukethe i-Iron-Chromium Alloys enezinhlaka ze-Cubic Crystal ezigxile kakhulu emzimbeni (BCC). Lokhu ngokuvamile kuvamile kazibuthe futhi akunakuba lukhuni ukwelashwa okushisa kepha kungaqiniswa ukusebenza kubanda.
● Insimbi Engagqwali Engagqwali: Ama-autenitic steel iningi elivimbela kakhulu. Kungeyona i-magnetic ne-non-herloble. Ngokuvamile, ama-auntenitic ansimbi ashibilika kakhulu.
● Insimbi Engagqwali Engagqwali: Ama-Martensitic Steress agwini aqine kakhulu futhi anzima kodwa awekho njengokumelana nokuphikisana namanye amakilasi amabili. Lezi zinsimbi zisebenza kakhulu, kazibuthe, futhi zilapha ukushisa.
● I-Dumplex Steel engenacala: Insimbi engenacala ye-Dumplex iqukethe i-mistolotion yesigaba ezimbili ne-mistolotion enezinhlamvu ze-Ferritic ne-auntenitic yensimbi engagqwali (ie Ferrite + Auston + Auston). I-Duplex Steel imayelana nokuqina okuphindwe kabili njengensimbi e-auntenitic noma ye-Ferritic.
● I-Treapitature-Harding (PH) Ama-Steringless Steel: I-Treapitation-Harding (PH) Ama-Steel Anamandla aphezulu aphezulu ngenxa yokuqina kwezulu.
3. Insimbi yensimbi
Ku-alloy steel, izilinganiso ezihlukile zezinto ezenziwayo ezisetshenziswayo, ukufezekisa izakhiwo ezifiselekayo (ezithuthukisiwe) ezifana nokushaywa kwe-weldurall, i-cortility, ukuqina kwemishini, njll. Ezinye zezinto ezenziwa ngokugqwala, njll. Ezinye zezinto ezenziwayo ezisetshenziswa kakhulu nemiphumela yazo zimi ngokulandelayo;
● I-manganese - yandisa amandla nobulukhuni, yehlisa i-actility kanye nokushiswa.
● I-Silicon - esetshenziswa njenge-deoxidizers esetshenziswa kwinqubo yokwenza insimbi.
● I-Phosphorus - yandisa amandla nobulukhuni futhi yehlisa ubulukhuni be-notch nomthelela wensimbi.
● I-Sulfure -DeCreases Cuctility, i-Notch Impact Glounce, kanye nokushiswa. Etholakala ngendlela yokufaka sulfide inclusions.
● I-Copper - ukumelana okuthuthukile kokugqwala.
● I-Nickel - Ikhulisa Ubunzima kanye namandla Omthelela Wensimbi.
● I-Molybdenum - yandisa ukuqina kwe-hardiaty futhi ithuthukisa ukumelana nokumelana kwama-low-alloy.
4. Insimbi yensimbi
Amathuluzi Amathuluzi anokuqukethwe okuphezulu kwekhabhoni (0.5% kuya ku-1.5%). Okuqukethwe okuphezulu kwe-carbon kunikeza ubunzima obukhulu namandla. Lezi zinsimbi zisetshenziselwa kakhulu ukwenza amathuluzi nokufa. Insimbi yethuluzi iqukethe amanani ahlukahlukene eTungsten, i-Cobalt, Molybdenum, ne-vagadium ukukhulisa ukushisa nokugqoka ukumelana nokuqina kwensimbi. Lokhu kwenza amathumbu ensimbi elungele ukusetshenziswa njengamathuluzi wokusika nokumba.
Iqembu lensimbi yeJindalai lihlala ligcwele ngokuphelele ngokusungula okuhle kwemikhiqizo yensimbi embonini. IJindalai ingakusiza ukhethe izinto ezifanele zensimbi ukuze uqinisekise ukuthi uthola okudingayo ngokushesha ngangokunokwenzeka lapho sekuyisikhathi sokuthenga. Uma ukuthengwa kwensimbi yensimbi kuseduze okuzayo, cela isilinganiso. Sizohlinzeka ngokuthola okukuthola ngqo imikhiqizo oyidingayo ngokushesha.
