Izizathu zokuqhekeka kwama-castables ngesikhathi sokubhaka ziyinkimbinkimbi, ezibandakanya izinga lokushisa, ikhwalithi yezinto ezibonakalayo, ubuchwepheshe bokwakha nezinye izici. Okulandelayo ukuhlaziya okuqondile kwezizathu nezixazululo ezihambisanayo:
1. Izinga lokushisa lishesha kakhulu
Isizathu:
Ngesikhathi sokubhaka ama-castables, uma izinga lokushisa lishesha kakhulu, amanzi angaphakathi akhuphuka ngokushesha, futhi umfutho we-steam owenziwe mkhulu. Uma idlula amandla aqinile we-castable, kuzovela imifantu.
Isixazululo:
Yakha ijika lokubhaka eliphusile futhi ulawule izinga lokushisa ngokuya ngezinto ezifana nohlobo nokujiya kokuphonswa. Ngokuvamile, isigaba sokuqala sokushisisa kufanele sihambe kancane, okungcono singeqi ku-50℃/h. Njengoba izinga lokushisa likhuphuka, izinga lokushisa lingasheshiswa ngokufanelekile, kodwa kufanele futhi lilawulwe cishe ku-100 ℃/h - 150 ℃/h. Phakathi nenqubo yokubhaka, sebenzisa irekhoda lokushisa ukuze uqaphe ukushintsha kwezinga lokushisa ngesikhathi sangempela ukuze uqinisekise ukuthi izinga lokushisa liyahlangabezana nezidingo.
2. Inkinga yekhwalithi yezinto ezibonakalayo
Isizathu:
Isilinganiso esingalungile se-aggregate ku-powder: Uma kukhona ama-aggregates amaningi kakhulu kanye ne-powder enganele, ukusebenza kwe-bonding ye-castable kuzokwehla, futhi imifantu izovela kalula ngesikhathi sokubhaka; ngokuphambene nalokho, i-powder eningi izokwandisa izinga lokuncipha kwe-castable futhi ibangele kalula imifantu.
Ukusetshenziswa okungalungile kwezithasiselo: Uhlobo nenani lezithasiselo zinomthelela obalulekile ekusebenzeni kokuphonswa. Isibonelo, ukusetshenziswa ngokweqile kwesinciphisi samanzi kungabangela uketshezi okweqile kwe-castable, okuholela ekuhlukaniseni phakathi nenqubo yokuqinisa, futhi kuzovela imifantu ngesikhathi sokubhaka.
Isixazululo:
Lawula ngokuqinile ikhwalithi yezinto zokusetshenziswa, futhi ukale ngokunembile izinto zokusetshenziswa njengezihlanganisi, izimpushana nezithasiselo ngokuya ngezidingo zefomula ezinikezwa umenzi. Njalo hlola futhi uhlole izinto zokusetshenziswa ukuze uqinisekise ukuthi usayizi wezinhlayiyana zazo, ukuhleleka kwazo kanye nokwakheka kwamakhemikhali kuyahlangabezana nezidingo.
Kumaqoqo amasha ezinto zokusetshenziswa, qala wenze isampula encane yokuhlola ukuhlola ukusebenza kwe-castable, efana noketshezi, amandla, ukuncipha, njll., lungisa ifomula nomthamo owengeziwe ngokwemiphumela yokuhlolwa, bese uwasebenzisa esikalini esikhulu ngemva kokuba sebefanelekile.
3. Izinkinga zenqubo yokwakha
Izizathu:
Ukuxuba okungalingani:Uma i-castable ingaxubeki ngokulinganayo ngesikhathi sokuxuba, amanzi kanye nezithako ezikuyo zizosatshalaliswa ngokungalingani, futhi ukuqhekeka kuzokwenzeka ngesikhathi sokubhaka ngenxa yokungafani kokusebenza ezingxenyeni ezahlukene.
Ukudlidliza okungahlanganisiwe: Phakathi nenqubo yokuthulula, ukudlidliza okungahlanganisiwe kuzobangela ama-pores nama-voids ngaphakathi kokuphonswa, futhi lezi zingxenye ezibuthakathaka zivame ukuqhekeka ngesikhathi sokubhaka.
Ukunakekela okungalungile:Uma amanzi angaphezulu kwe-castable engagcinwa ngokugcwele ngemva kokuthululwa, amanzi ahwamuka ngokushesha, okuzobangela ukuncipha okukhulu nokuqhekeka komhlaba.
Isixazululo:
Sebenzisa ukuxuba ngomshini futhi ulawule ngokuqinile isikhathi sokuxuba. Ngokuvamile, isikhathi sokuxuba se-mixer ephoqelelwe asikho ngaphansi kwemizuzu engu-3-5 ukuqinisekisa ukuthi i-castable ixubene ngokulinganayo. Phakathi nenqubo yokuxuba, engeza inani elifanele lamanzi ukuze wenze okuphonswayo kufinyelele uketshezi olufanele.
Lapho udlidliza, sebenzisa amathuluzi afanele okudlidliza, njengezinduku ezidlidlizayo, njll., futhi udlidlizele ngokulandelana okuthile kanye nesikhala ukuze uqinisekise ukuthi okuphonswayo kuminyene. Isikhathi sokudlidliza asifanele amabhamuza nokucwila ebusweni be-castable.
Ngemuva kokupholisa, ukuthambisa kufanele kwenziwe ngesikhathi. Ifilimu yepulasitiki, amacansi otshani abamanzi nezinye izindlela zingasetshenziswa ukugcina ubuso bomswakama obuphonswayo, futhi isikhathi sokuphulukisa ngokuvamile asibi ngaphansi kwezinsuku ezingu-7-10. Kuma-castable amavolumu amakhulu noma ama-castable akhiwe endaweni enezinga lokushisa eliphezulu, ukuphulukiswa kwesifutho nezinye izinyathelo nazo zingathathwa.
4. Inkinga yendawo yokubhaka
Imbangela:
Izinga lokushisa le-ambient liphansi kakhulu:Uma ubhaka endaweni yokushisa ephansi, isivinini sokuqina kanye nokomisa kwe-castable sihamba kancane, futhi kulula ukuqandisa, okuholela ekulimazeni kwesakhiwo sangaphakathi, ngaleyo ndlela kuqhekeke.
Ukungena komoya okungalungile:Ngesikhathi senqubo yokubhaka, uma umoya omncane ungabushelelezi, amanzi aphuma ngaphakathi kwe-castable awakwazi ukukhishwa ngesikhathi, futhi aqoqa ngaphakathi ukuze enze ukucindezela okukhulu, okubangela ukuqhekeka.
Isixazululo:
Uma izinga lokushisa lendawo lingaphansi kuka-5℃, kufanele kuthathwe izinyathelo zokushisisa, njengokusebenzisa i-heater, ipayipi lesitimu, njll. ukuze kushiswe kuqala indawo yokubhaka, ukuze izinga lokushisa lendawo likhuphuke libe ngaphezu kuka-10℃-15℃ ngaphambi kokubhaka. Phakathi nenqubo yokubhaka, izinga lokushisa elizungezile kufanele futhi ligcinwe lizinzile ukuze kugwenywe ukushintshashintsha kwezinga lokushisa okweqile.
Setha ngokufanelekile izimbobo ukuze uqinisekise ukungena kahle komoya ngesikhathi sokubhaka. Ngokusho kobukhulu nokuma kwemishini yokubhaka, ama-vents amaningi angasethwa, futhi ubukhulu bezikhala bungalungiswa njengoba kudingeka ukuze kuqinisekiswe ukuthi umswakama ungaphuma kahle. Ngesikhathi esifanayo, ukunakekelwa kufanele kuthathwe ukuze kugwenywe ukubeka ama-castable ngqo emigodini ukuze kugwenywe ukuqhekeka ngenxa yokoma komoya wendawo ngokushesha.
