Ukukhetha impahla eluhlaza
Ukunambitheka kwempahla eluhlaza kufanele kuthuthuke ngokunambitheka kwezethusiizinhlobo.Uma uncibilikisa ithusi elingabalulekile, uma izinga lokushaja lithembekile, ngezinye izikhathi ukusetshenziswa kwezinto ezindala kungafinyelela ku-100%.Kodwa-ke, ukuze kuqinisekiswe ikhwalithi yokuncibilika futhi kuncishiswe ukulahleka kokuvutha, ukusetshenziswa kweshaja ehlukaniswe kancane njengama-sawdust ahlukahlukene noma ama-zinc chips akufanele kudlule ama-30%.Indawo yokuhlola: Uma usebenzisa u-50% we-cathode copper kanye no-50% wezinto ezindala zethusi, isikhathi esidingekayo sokuncibilikisa yisona eside kakhulu futhi ukusetshenziswa kwamandla kuphezulu kakhulu.Uma ingot ye-zinc ishisiswe kuqala ibe ngu-100 ~ 150 ℃ futhi yondliwe ngamaqoqo, kunenzuzo kakhulu ukuthi izike futhi inyibilike echibini elincibilikisiwe ngokushesha, okunganciphisa ukulahlekelwa okuvuthayo kwensimbi.Ukwengeza inani elincane le-phosphorus kungakha ifilimu elinwebeka kakhulu le-oxide elakhiwe ngo-2ZnO.p2o2 ebusweni bechibi elincibilikisiwe.Ukwengeza inani elincane le-aluminium, elifana ne-0.1% ~ 0.2%, lingakha ifilimu evikelayo ye-Al2O3 ebusweni bechibi elincibilikisiwe, futhi kusize ukugwema nokunciphisa ukuguquguquka kwe-zinc nokuthuthukisa izimo zokuphonsa.Lapho inani elikhulu lezinto ezindala zisetshenziselwa ukuncibilikisa ithusi, kufanele kwenziwe isinxephezelo sangaphambi kwesikhathi esifanele kwezinye izakhi ezinokulahlekelwa okukhulu kokuncibilika.Isibonelo, inani lesinxephezelo langaphambili le-zinc lingu-0.2% uma kuncibilikiswa ithusi elinezinc ephansi, inani lesinxephezelo langaphambili le-zinc lingu-0.4% -0.7% lapho kuncibilikiswa ithusi le-zinc eliphakathi, kanye nenani lesinxephezelo langaphambili le-zinc. 1.2% -2.0% lapho kuncibilika ithusi elinezinki eliphezulu.
Ukulawula inqubo yokuncibilika
Ukuhleleka okujwayelekile kwezengezo lapho kuncibilika ithusi: ithusi, impahla endala kanye ne-zinc.Lapho kuncibilika ithusi elivela ezingxenyeni zensimbi ezihlanzekile, ithusi kufanele lincibilike kuqala.Ngokuvamile, lapho ithusi lincibilika futhi lishiswa ngokweqile lifinyelela izinga elithile lokushisa, kufanele likhishwe ngendlela efanele (isb. nge-phosphorus) bese i-zinc kufanele incibilike.Uma ukushaja kuqukethe ukushaja kwethusi elidala, ukulandelana kokushaja kungalungiswa ngokufanele ngokuvumelana nezimo zangempela ezifana nezici zezingxenye ze-alloy kanye nohlobo lwesithando somlilo sokuncibilika.Ngenxa yokuthi izinto ezindala ngokwazo ziqukethe i-zinc, ukuze kuncishiswe ukuncibilika kwesici se-zinc, izinto ezidala zethusi kufanele zivame ukungezwa futhi zincibilike ekugcineni.Kodwa-ke, izingcezu ezinkulu zenkokhelo azifanele ukushajwa kokugcina nokuncibilika.Uma ukushaja kumanzi, akufanele kufakwe ngokuqondile ekuncibilikeni.Uma ukushaja okumanzi kwengezwa ngaphezu kwesinye inkokhelo engancibilikisiwe, kuzodala isikhathi sokumisa nokushisa ngaphambi kokuba kuncibilike, okungazuzisi nje kuphela ukugwema ukuncibilika kwe-inhalation, kodwa futhi nokugwema ezinye izingozi.Ukwengezwa kwe-Zinc ekushiseni okuphansi kuyisimiso esiyisisekelo okufanele silandelwe cishe kuzo zonke izinqubo zokuncibilikisa zethusi.Ukwengeza i-zinc ekushiseni okuphansi akukwazi nje ukunciphisa ukulahlekelwa okuvuthayo kwe-zinc, kodwa futhi kusiza ukuphepha kokusebenza kwe-smelting.Uma kuncibilikiswa ithusi esithandweni sokungenisa amandla se-iron-core induction, ngokuvamile akudingekile ukwengeza i-deoxidizer ngoba incibilika ngokwayo, okungukuthi, ichibi elincibilikisiwe lesikhashana, liqukethe inani elikhulu le-zinc.Kodwa-ke, lapho izinga lokuncibilika liphansi, i-0.001% ~ 0.01% i-phosphorus nayo ingangezwa ngokuvumelana nesisindo esiphelele senkokhelo ye-deoxidation eyisizayo.Ukwengeza inani elincane le-copper-phosphorus master alloy ekuncibilikeni kungakhuphula ukuncibilika kokuncibilika ngaphambi kokuba kukhishwe esithandweni.Uma sithatha i-H65 yethusi njengesibonelo, indawo yayo yokuncibilika ingu-936°C.Ukuze wenze igesi kanye nomagazini ekuncibilikeni kuntante futhi kukhishwe ngesikhathi, ngaphandle kokubangela ukuguquguquka okuningi kwe-zinc kanye nokuhogela kokuncibilika, izinga lokushisa elincibilikayo livame ukulawulwa ku-1060 ~ 1100 ° C.Izinga lokushisa linganyuswa ngokufanelekile libe ngu-1080 ~ 1120 ℃.Ngemuva kokuthi "ukushisa umlilo" izikhathi ezi-2 kuya kwezi-3, uphonswa kusiguquli.Mboza ngamalahle abhakiwe ngesikhathi sokuncibilika, futhi ugqinsi lwesendlalelo sokumboza kufanele lube lukhulu kuno-80mm.
