Yiziphi izinyathelo zokwakha zokusebenzisa ama-castable?

Kunezici eziningi ezithinta ukusebenza kwama-castable, njengokukhethwa kwempahla, ukwakhiwa, nokunakekelwa. Ukubaluleka kokwakha nakho kudlala indima ebalulekile ekusebenzeni kwama-castable. Umhleli olandelayo uzokuchazela izindlela zokwakha ezisetshenziswayo ezisetshenziswa kakhulu:

A. Ukuthela indlela yokwakha

1. Ukuhlola: Hlola ukuthi isikhunta sisekelwe kahle yini, azikho izikhala nokuchezuka, futhi imfucumfucu esesikhunjini iyahlanzwa, ukuthi amahange (izipikili zensimbi engagqwali ezingashisi ezingashisi) ashiselwe ngokuqinile, kanye nobuso bamahange. imbozwe ngopende noma isikhwama sepulasitiki ukuze isivimbe amandla Anweba ngemva kokushisisa.

2. Ukuthulula: Thela okuxubile okuthulula esibunjeni, faka induku edlidlizayo ukuze idlidlize, bese unyakazisa induku edlidlizayo ngesivinini esifanayo, bese uyikhipha kancane.

3. Indawo yokuthela inkulu kakhulu, ingathululwa ngezingqimba nezingxenye, futhi ingasebenza ngokuphambana. Udonga luthululelwa ngezingqimba, isikhathi ngasinye mayelana ne-900mm, phezulu kwesithando somlilo kuhlukaniswa futhi kuthululwe, bese kuphakanyiswa.

4. Ukuphulukisa nokudiliza: izinga lokushisa kwemvelo> 20 ℃, isikhunta singahlakazwa ngemva kwe-4H, <20 ℃, isikhunta singahlehliswa ngemva kokuphulukiswa kwe-6-7H, uma imiphetho yendawo namakhona konakalisiwe, ingalungiswa. . (Isikhathi esithile sokudiliza sincike ezimeni zesayithi).

B. Indlela yokwakha yokugcoba

1. Okokuqala hlola ukuthi amahange (izinzipho zensimbi engagqwali ze-palladium ezingashisi) ashiselwe ngokuqinile. Penda amahange noma uwasonge ngezikhwama zepulasitiki ukuze uvale amandla okunweba ngemva kokufudumeza.

2. Sebenzisa ukugcotshwa okwenziwa ngesandla kwe-castable exubekile ngqo endaweni yokusebenza.

3. Indawo yokusebenza kufanele isetshenziswe ngokuqhubekayo ngezingqimba ukusuka phansi kuye phezulu. Ukuphakama kwesendlalelo ngasinye kungaba ngu-900mm, kanti ukujiya kongqimba ngalunye kungaba ngu-80mm. Uma ukujiya kufinyelela kusayizi odingekayo, sebenzisa ithuluzi ukupholisha indawo yokwakha.

4. Faka isicelo ngokuqhubekayo phezulu kwendawo yokwakha ezingxenyeni, nesigaba phakathi kwamalungu amabili okwandisa, isikhathi ngasinye 30-50mm, lapho ubukhulu bufinyelela ubukhulu obudingekayo, sebenzisa ithuluzi lokupholisha indawo yokwakha.

5. Ukuze kufakwe i-thermal insulation lining yamapayipi avundlile anobubanzi obukhulu, indlela yokwakha i-lining ezigabeni kuqala bese ibeka uxhumano kufanele yamukelwe. Lapho ipayipi lakhiwe ngokwezigaba, beka ipayipi ngokuvundlile, sebenzisa ulwelwesi olungaphansi oluyisiyingi kuqala, futhi ngemva kokwelapha ngokwemvelo amahora angu-4-8, vula ipayipi libe ngu-180° futhi ufake olunye uhlaka oluyisiyingi, futhi wenze ukwelashwa ngokuhlanganyela ngemva kokuba ipayipi kuxhunyiwe.

C. Futha indlela yokwakha

1. Shisela izinzipho zensimbi ze-palladium noma i-mesh yensimbi (insimbi engagqwali engashi) egobolondweni lesithando somlilo kuqala.

2. Faka upende wokufutha emshinini wokufutha, sebenzisa umoya ocindezelwe (ingcindezi engu-0.10-0.15MPa) ukuze uthumele ingxube emlonyeni, bese wengeza inani elifanele lamanzi noma i-ejenti yokuhlanganisa amakhemikhali ukuze uxube nempahla, bese uyifafaza ku-nozzle. indawo yokwakha.

3. I-nozzle outlet kufanele ibe yi-perpendicular ebusweni bokwakha, ibanga liyi-1-1.5m, ukufafaza kufanele kuqhubeke, futhi ubukhulu bokufafaza ngakunye kufanele bube ngaphansi kuka-200mm.

4. Uma uhlaka lokufafaza kwendawo yokwakha likhulu kakhulu, kufanele lufafazwe ngezingqimba, kodwa kufanele lwenziwe ngemuva kokuba ungqimba lwangaphambili lunamandla anele. Ngemuva kokufafaza, indawo yokusebenza kufanele yenziwe bushelelezi futhi i-rebound material kufanele ihlanzwe.

Ukufingqa, ukulandela ngokuqinile izindlela zokwakha nezinyathelo kudlala indima ebalulekile ekusebenzeni kwama-castable aphikisayo.
