I-Chromium-nickel alloy 600 kanye nobuchwepheshe bayo bokucubungula

I-alloy 600 (UNSN0660) iyingxubevange ene-nickel njengengxenye eyinhloko nokumelana nezimo ezihlukahlukene zokugqwala. I-alloy 600 (UNSN0660) ingasetshenziswa ezindaweni ezinezinga lokushisa eliphansi kanye nezinga lokushisa eliphezulu lika-20000F (10930C). Ayinawo uzibuthe futhi ingashiselwa ukumelana nokugqwala. Okuqukethwe kwayo kwe-nickel alloy kuphezulu, futhi inokumelana nokugqwala okuqinile nokumelana okuhle nokuqhekeka kokugqwala kwe-chloride. I-Chromium iyenza ifanelekele izindawo ezine-oxidation ephansi.

Izici ezijwayelekile

I-alloy 600 (i-UNS eqokwe ukuthi i-N0660) iyingxubevange ye-chrome-nickel, eklanyelwe izindawo ezisukela kumazinga okushisa aphansi ukuya ku-2000 degrees Fahrenheit (1093 degrees Celsius). Ingxubevange ayinamagnetic futhi kulula ukuyishisela. I-alloy 600 isetshenziswa emikhakheni ehlukene yokulwa nokugqwala. Okuqukethwe kwayo okuphezulu kwe-nickel kubonisa izinga elithile lokumelana nokugqwala ezindaweni ezinedigri encishisiwe yokugqwala, kuyilapho i-chromium ku-alloy inokumelana nokugqwala endaweni ebuthakathaka ye-oxidation. Okuqukethwe kwe-nickel ephezulu ku-alloy kunokumelana okukhethekile ne-chloride corrosion fission.

Inkambu yesicelo:

① Imishini yokucubungula amakhemikhali nokudla

② Isigayo samaphepha kanye ne-alkali digester

③ Isishintshi sokushisa

④ Isithulisi sokwelapha ukushisa kanye ne-evaporator.

Ukwelashwa okushisayo:

Ingxubevange 600 ngeke lukhuni ngesikhathi ukwelashwa ukushisa. Ukuqina kwe-alloy kungathuthukiswa kuphela ngokwelashwa okubandayo. Ngemuva kokusebenza okubandayo, i-alloy iyaxhunywa ukuze kuthambise impahla. Ukuthambisa kudinga ukwenziwa kusukela ekushiseni kokuqala okungu-1600 degrees Fahrenheit (871 degrees Celsius) kuya ku-2100 degrees Fahrenheit (1149 degrees Celsius). Lapho izinga lokushisa likhuphuka lifinyelela ku-1800 degrees Fahrenheit (982 degrees Celsius) noma ngaphezulu, izinhlayiya zizokhula ngokushesha. Nokho, uma impahla ithambe ngo-1900 degrees Fahrenheit (1038 degrees Celsius) ngesikhathi esifushane kakhulu, izinhlayiya zingavinjelwa ukuba zibe zinkulu kakhulu. Ukupholisa kancane nokucisha kungagcina ubulukhuni be-alloy 600 cishe okufanayo.

Iyacubungula:

I-alloy 600 ibonisa izakhiwo ezinhle ezenza ukubanda, ezihlobene nensimbi ye-Ni-Cr equkethe. Okuqukethwe kwayo kwe-nickel ephezulu kuvimbela ukuguqulwa kwayo ukusuka ku-austenitic steel ukuya ku-martensitic steel, okuzokwenzeka lapho kwakhiwa ingxube yensimbi engagqwali engu-301 kanye nengxube yensimbi engu-304 ebandayo. Uma kuqhathaniswa nama-alloy angu-301 kanye nama-alloys angu-304, izinga lokuqina elisebenzayo lama-alloys angu-600 liphansi, futhi lingasetshenziselwa ukwakheka kokugoqa ngezindlela ezihlukahlukene, kodwa inani elikhulu lokuguqulwa lizokwenzeka phakathi kwe-annealing kanye ne-annealing.

Uma kusetshenziswa i-high*temperature annealing, ingxubevange 600 ikhiqiza izinhlayiya ezinkulu uma kuqhathaniswa ukuze kutholwe izici ezilethwa ukunyuka kwezinga lokushisa, futhi indawo engaphezulu yakheka ebangeni eliphezulu ukuze kwakheke ukuguquguquka okusobala, okubizwa ngokuthi “ikhasi lewolintshi”. Lesi simo sibangelwa izinhlayiya ezinkulu, ngokuvamile ezibhekwa njengengozi kuzakhiwo ezibonakalayo.

Welding:

I-standard resistance welding kanye ne-fusion welding yensimbi engagqwali ingasetshenziselwa i-alloy 600. Ama-electrodes nezintambo i-welding alloy 600 nezinye izinto zingatholakala emakethe. Ngenxa yokuthi le alloy izokhiqiza ama-oxide ane-adhesion eqinile, ukuvikelwa kwegesi ye-inert kufanele kusetshenziswe ngokunengqondo.
