Funda malunga neePropati kunye nokuSetyenziswa kwesinyithi sobhedu

I-Jindalai (Shandong) ye-Steel Group Co., Ltd. inikezela ngeemveliso ezahlukeneyo zobhedu ngobukhulu kunye nobungakanani ukuhlangabezana neemfuno zayo nayiphi na iprojekthi.

2. Iimpawu
Iimpawu ezichanekileyo zobhedu ezahlukeneyo zixhomekeke ekubunjweni kwe-alloy yobhedu, ngokukodwa umlinganiselo wobhedu-zinc. Ngokuqhelekileyo, nangona kunjalo, zonke iibhedu zixabiswa ngenxa yobuchule babo okanye ukukhululeka apho isinyithi sinokubunjwa kwiimo ezifunwayo kunye neefom ngelixa zigcina amandla aphezulu.

Ngelixa kukho iiyantlukwano phakathi kweebrasi ezinezinki eziphezulu nezisezantsi, zonke iibrasi zithathwa njengezingafanekiyo kunye ne-ductile (iibrasi zezinc ezisezantsi ngakumbi). Ngenxa yeqondo eliphantsi lokunyibilika, ubhedu lunokuphoswa ngokulula. Nangona kunjalo, kwizicelo zokuphosa, umxholo ophezulu we-zinc udla ngokuthandwa.

Iibrasi ezinomxholo ophantsi we-zinc zinokusebenza ngokulula, zifakwe kwi-welded kunye ne-brazed. Umxholo ophezulu wobhedu uvumela isinyithi ukuba senze umaleko we-oxide okhuselayo (i-patina) kwindawo yayo ekhusela ukubola, ipropati exabisekileyo kwizicelo ezibonisa isinyithi ukufuma kunye nemozulu.

Isinyithi sinobushushu obuhle kunye ne-conductivity yombane (i-conductivity yayo yombane inokusuka kwi-23% ukuya kwi-44% yobhedu olusulungekileyo), kwaye iyanxila kunye ne-spark resistant. Njengobhedu, iipropati zayo ze-bacteriostatic ziye zabangela ukusetyenziswa kwayo kwiindawo zokuhlambela kunye nezibonelelo zempilo.

I-Brass ithathwa njenge-low friction kunye ne-non-magnetic alloy, ngelixa iimpawu zayo ze-acoustic zibangele ukusetyenziswa kwayo kwizixhobo ezininzi zomculo 'zebhendi yobhedu'. Abazobi kunye nabayili bezakhiwo bayayixabisa ipropathi yobuhle bentsimbi, njengoko inokuveliswa kuluhlu lwemibala, ukusuka kubomvu obunzulu ukuya kumthubi obugolide.

3. Izicelo
Iipropati ezixabisekileyo ze-Brass kunye nokulula kokuveliswa kwemveliso yenze enye yezona zinto zisetyenziswa kakhulu. Ukuqulunqa uluhlu olupheleleyo lwazo zonke izicelo ze-brass'inokuba ngumsebenzi omkhulu, kodwa ukufumana ingcamango yamashishini kunye neentlobo zeemveliso apho ubhedu lufumaneka khona sinokuhlula kwaye sishwankathele usetyenziso oluthile olusekelwe kwibakala lobhedu olusetyenzisiweyo:
● Ibhedu yokusika yasimahla (umz. C38500 okanye 60/40 yobhedu):
● Amandongomane, iibholiti, iindawo ezinemisonto
● Izikhululo
● IiJethi
● Iimpompo
● Izitofu

4. Imbali
I-alloys ye-Copper-zinc yaveliswa kwasekuqaleni kwenkulungwane ye-5 BC e-China kwaye yayisetyenziswa ngokubanzi kumbindi we-Asiya ngenkulungwane yesi-2 neye-3 BC. Ezi ziqwenga zentsimbi zokuhombisa, nangona kunjalo, zinokuthiwa ngcono ngokuba 'zii-alloys zendalo,' njengoko kungekho bungqina bokuba abavelisi babo basebenzise ngobuchule ubhedu kunye ne-zinc. Endaweni yoko, kusenokwenzeka ukuba iialloyi zanyibilikiswa kwintsimbi ekrwada yobhedu enezinki, evelisa iintsimbi ezikrwada ezifana nobhedu.

Amaxwebhu amaGrike namaRoma acebisa ukuba ukuveliswa ngabom kweealloys ezifana nobhedu lwanamhlanje, kusetyenziswa icopperand zinc oxide-rich ore eyaziwa ngokuba yicalamine, kwenzeka malunga nenkulungwane yoku-1 BC. Ubhedu lweCalamine lwaveliswa kusetyenziswa inkqubo yesamente, apho ubhedu lwalunyibilikiswa khona. i-crucible nge-ground smithsonite (okanye i-calamine) ore.

Kubushushu obuphezulu, i-zinc ekhoyo kwintsimbi ekrwada ijika ibe ngumphunga kwaye igqobhoze kubhedu, ngaloo ndlela ivelisa ubhedu olusulungekileyo olunomthamo we-zinc oyi-17-30%. Le ndlela yokuvelisa ubhedu yayisetyenziswa phantse iminyaka engama-2000 ukuya kutsho ekuqaleni kwenkulungwane ye-19. Kungekudala emva kokuba amaRoma efumene indlela yokuvelisa ubhedu, le ngxubevange yayisetyenziselwa ingqekembe kwimimandla yeTurkey yanamhlanje. Kungekudala oku kwasasazeka kubo bonke uBukhosi baseRoma.

5. Iintlobo
'Ubhedu' ligama eliqhelekileyo elibhekisa kuluhlu olubanzi lweealloyi zobhedu-zinc. Enyanisweni, kukho ngaphezu kwe-60 iintlobo ezahlukeneyo zobhedu ezichazwe yi-EN (i-European Norm) iMigangatho. Ezi ngxubevange zinokuba noluhlu olubanzi lweziqulatho ezahlukeneyo ngokuxhomekeke kwiipropati ezifunekayo kwisicelo esithile.

6. Imveliso
I-Brass idla ngokuveliswa kwi-copper scrap kunye ne-zinc ingots. Ubhedu olulahliweyo lukhethwa ngokusekelwe kukungcola kwalo, njengoko izinto ezithile ezongezelelweyo zifunwa ukwenzela ukuvelisa ibakala elichanekileyo lobhedu olufunekayo.
Ngenxa yokuba i-zinc iqalisa ukubila ize ibe ngumphunga kwi-1665°F (907°C), ngaphantsi kwendawo yokunyibilika kobhedu ngo-1981° F (1083°C), ubhedu kufuneka luqale lunyibilike. Xa inyibilika, i-zinc yongezwa ngokomlinganiselo ofanelekileyo kwibakala lobhedu oluveliswayo. Ngelixa isibonelelo esithile senziwa kwilahleko ye-zinc ukuya kumoya.

Ngeli xesha, naziphi na ezinye izinyithi ezongezelelweyo, ezifana nelothe, i-aluminium, i-silicon okanye i-arsenic, zongezwa kumxube ukwenza i-alloy efunekayo. Emva kokuba i-alloy etyhidiweyo ilungile, igalelwe kwi-molds apho iqina kwii-slabs ezinkulu okanye iibhilidi. Iibhilithi - rhoqo zealpha-beta brass - zinokusetyenzwa ngokuthe ngqo zibe yiingcingo, imibhobho, kunye neityhubhu ngokusebenzisa i-extrusion eshushu, ebandakanya ukutyhala isinyithi esishushu kwidiyizi, okanye iforum eshushu.

Ukuba azikhutshwanga okanye zenziwe, iibhilithi ziphinda zifudunyezwe kwaye zondliwa ngeerola zensimbi (inkqubo eyaziwa ngokuba yi-hot rolling). Isiphumo singama-slabs anobunzima obungaphantsi kwesiqingatha se-intshi (<13mm). Emva kokupholisa, ubhedu luthi lutyiswe ngomatshini wokugaya, okanye i-scalper, enqumla umaleko obhityileyo kwisinyithi ukuze kususwe iziphene zokuphosa umphezulu kunye ne-oxide.

Ngaphantsi kwe-atmosphere yerhasi ukuthintela i-oxidization, i-alloy iyafudunyezwa kwaye iqengqeleke kwakhona, inkqubo eyaziwa ngokuba yi-annealing phambi kokuba iphinde isongwe kumaqondo obushushu apholileyo (cold rolling) ukuya kumaphepha amalunga ne-0.1" (2.5mm) ubukhulu. isakhiwo sangaphakathi seenkozo zobhedu, okubangela ukuba isinyithi esinamandla ngakumbi kwaye sinzima kakhulu.

Ekugqibeleni, amashiti ayasarha aze achetywe ukuze avelise ububanzi nobude obufunekayo. Onke amaphepha, atyhidiweyo, akhutshiweyo, akhutshiweyo, kunye nezinto zobhedu ezikhutshiweyo zinikwa ukuhlamba iikhemikhali, ngokuqhelekileyo, ezenziwe nge-hydrochloric kunye ne-sulfuric acid, ukususa isikali esimnyama sobhedu kunye nokungcolisa.

I-Jindalai inventory sheets zethusi kunye neekhoyili kubukhulu ukusuka kwi-0.05 ukuya kwi-50mm, kwaye kwi-annealed, ikota yobunzima, isiqingatha sobunzima, kunye nobunzima obugcweleyo. Eminye imimoya kunye nealloys ziyafumaneka ngokunjalo. Thumela umbuzo wakho kwaye siya kukuvuyela ukubonisana nawe ngobuchule.
