Amashubhu Ensimbi Engagqwali Engenamthungo Ye-Austenitic Yebanga Le-Urea

Lolu hlobo lwepayipi lensimbi engagqwali elingenamthungo lusetshenziswa kakhulu emishinini ebalulekile nasezinhlelweni eziyinhloko zezitshalo zokwenziwa kwe-ammonia kanye nokukhiqiza i-urea. Izinto zokusetshenziswa zihlungwa nge-electroslag remelting (ESR), okuqinisekisa ubumsulwa obuphezulu kanye nokufana kwesakhiwo. Ngesikhathi sokukhiqiza, ngaphezu kokulawula ukuhlanzeka okuqinile, kugxilwa kakhulu ekuphathweni kokwelashwa kokushisa okunembile ukuze kufezwe ukusebenza kahle kwensimbi.

Njengamanje, imikhiqizo enjalo yensimbi engagqwali ye-urea eShayina isancike kakhulu ekungenisweni kwempahla. Inkampani yethu ikhiqiza ngokuzimela ama-stels angagqwali e-urea e-ultra-pure, ikakhulukazi afaka phakathi i-316Lmod ne-S31050 emsulwa kakhulu. Womabili la mazinga angewensimbi engagqwali e-austenitic ngokugcwele, emsulwa kakhulu, aklanyelwe ngqo ukunqoba izinkinga zokugqwala ezikhethiwe ezibangelwa yizigaba ze-ferrite ezindaweni ze-ammonia ne-carbamate ngesikhathi sokwenziwa kwe-urea.

Kuyo yonke inqubo yokukhiqiza, yonke imikhiqizo yenziwa ngokuhambisana ngokuqinile nezindinganiso ezifanele. Ngemva kokuphumelela ukuhlolwa kweHughes, ikhombisa ukusebenza okuhle kakhulu kokumelana nokugqwala. Ngaphezu kokusetshenziswa kwe-urea ne-ammonia, lezi zinto zisetshenziswa kabanzi embonini yamandla e-hydrogen ngenxa yokumelana kwazo okuhle kakhulu nokugqwala kanye nokuqina kwezinto.

Ukuqinisekisa ikhwalithi ephezulu yobuso bezicelo ezihlanzekile kakhulu nezimelana nokugqwala, kwenziwa ukuhlolwa okuqinile kobulukhuni bobuso ngesikhathi sokukhiqiza. Izinsimbi zokulinganisa ubulukhuni bobuso obunembile kakhulu zisetshenziselwa ukuhlola kokubili ubuso bangaphakathi nobangaphandle, kugxilwe kakhulu esimweni sobuso bangaphakathi. Amaphuzu amaningi okulinganisa aqoshwa ukuqinisekisa ikhwalithi yobuso ehambisanayo nefanayo. Ngezinqubo zokukhiqiza ezilawulwayo kanye nezinqubo zokuhlola eziqinile, amashubhu athola ubuso obubushelelezi, obungenamaphutha, anciphisa ngempumelelo ukugcinwa kwemidiya kanye nezingozi zokugqwala, futhi ahlangabezane ngokugcwele nezidingo zezitshalo ze-urea kanye nezinhlelo zokudlulisa uketshezi oluhlanzekile kakhulu.

Ukuqinisekisa izinga eliphezulu lokuthembeka komkhiqizo kanye nobuqotho besakhiwo, wonke amashubhu ensimbi engagqwali angenamthungo ahlolwa ngogesi ngesikhathi sokukhiqizwa. Le ndlela yokuhlola engonakalisi isetshenziselwa ukuthola amaphutha aphezulu naseduze kobuso, okuhlanganisa imifantu, ama-pinhole, kanye nokunye ukungapheleli okungathinta ukusebenza. Ngokulandela ngokuqinile izinqubo zokuhlola ezijwayelekile nokusebenzisa imishini yokuhlola ethuthukisiwe, siqinisekisa ikhwalithi eqhubekayo kanye nokusebenza okuthembekile kwamashubhu ethu ezisetshenziswayo ezibalulekile njenge-urea, i-ammonia, kanye nezinhlelo zenqubo yokuhlanzeka okuphezulu.

• Okuqukethwe okuphansi kwe-silicon ukuvimbela ukugqwala kwesevisi ye-urea

• Ukumelana okuhle kakhulu nokugqwala kwe-ammonium carbamate

• Isakhiwo esingenamthungo siqinisekisa ukumelana nokucindezela okuphezulu

• Isakhiwo esincane sensimbi engagqwali esihlanzekile kakhulu

• Ifanele izindawo ezinokushisa okuphezulu kanye nezinga eliphezulu le-urea

Amashubhu ensimbi engagqwali e-austenitic angenamthungo e-Urea asetshenziswa kabanzi ezindaweni ezibucayi nezingcolisa kakhulu lapho kudingeka khona ubumsulwa obuphezulu kanye nokumelana nokugqwala. Izicelo ezijwayelekile zifaka:

• Amayunithi okwenziwa kwe-Urea kanye nokukhiqiza i-ammonia

• Imishini yokucindezela okuphezulu ezitshalweni zokucubungula umanyolo namakhemikhali

• Ama-condenser e-Carbamate, ama-stripper, kanye nama-heat exchanger

• Izinhlelo zamapayipi egesi ahlanzekile kakhulu kanye noketshezi

• Amandla e-hydrogen kanye nezikhungo zamandla ahlanzekile ezihlobene nawo

Lawa mashubhu ahlinzeka ngokusebenza okuthembekile ngaphansi kwezimo zokushisa okuphezulu, umfutho ophezulu, kanye nezimo zemidiya ezinamandla, okuqinisekisa ukuphepha nokusebenza kwesikhathi eside.

Q1: Iyini ishubhu yensimbi engagqwali ye-austenitic ye-urea-grade?
Ishubhu lensimbi engagqwali le-austenitic elisezingeni le-Urea liyishubhu elingenamthungo elihlanzekile kakhulu elenzelwe ngqo isevisi ye-urea ne-ammonia. Linokungcola okuphansi kakhulu kanye nokuqukethwe kwe-ferrite, okunikeza ukumelana okuhle kakhulu nokugqwala okukhethiwe ezindaweni ze-carbamate ne-ammonia.

Umbuzo 2: Kungani okuqukethwe kwe-ferrite okuphansi kubalulekile ekusetshenzisweni kwe-urea?
Izigaba ze-Ferrite zisengozini enkulu yokugqwala okukhethiwe ezindaweni zokwenziwa kwe-ammonia ne-urea. Izinsimbi ezingagqwali ze-Urea zenzelwe isakhiwo esiqinile ngokuphelele ukuze kuqedwe izingozi zokugqwala ezihlobene ne-ferrite nokuqinisekisa ukuthembeka kwenkonzo yesikhathi eside.

UMBUZO 3: Yimaphi amamaki avame ukusetshenziswa kumashubhu angenamthungo ebanga le-urea?
Amazinga avamile ensimbi engagqwali ebanga le-urea afaka phakathi i-316Lmod emsulwa kakhulu kanye ne-S31050. Lawa mazinga enzelwe ngqo ukumelana nokugqwala okuphezulu kanye nokuqina ngaphansi kwezimo zesevisi ye-urea yokushisa okuphezulu kanye nengcindezi ephezulu.

Umbuzo 4: Yiziphi izinqubo zokukhiqiza ezisetshenziswayo ukuqinisekisa ikhwalithi yomkhiqizo?
Izinto zokusetshenziswa zihlungwa ngokusebenzisa i-electroslag remelting (ESR), kulandelwe ukulawulwa okuqinile kokuhlanzeka kanye nezinqubo zokwelashwa kokushisa. Ithubhu ngalinye lihlolwa ngokuphelele, okuhlanganisa ukuhlolwa kwamanje kwe-eddy kanye nokuhlolwa kokugqwala njengokuhlolwa kwe-Hughes.
