Ungabhekana kanjani nezimbobo zesihlabathi ekukhiqizweni kobukhulu obuncane bodonga oluncane lwe-rouctile iron izingxenye zomugqa wokubumba ovundlile?

Mayelana nezinkinga zesihlabathi ezenzeka ekwenziweni kwama-cartile iron castlings ezincane (ukushuba odongeni Izindlela ezithile zokwelashwa zinjengokulandelayo:

1. Hlaziya izimbangela zezimbobo zesihlabathi. Umongo wezimbobo zesihlabathi ukwakheka kwezimbobo ebusweni noma ngaphakathi kwezimali ngenxa yokufakwa noma ukuguguleka kwezinhlayiya zesihlabathi ngesikhathi senqubo yokugcwalisa yensimbi ebilisiwe. Ama-carings amancane azwela ngokwengeziwe ekuhlanganeni, emandleni, kanye nokuqina kokuqina kwesihlabathi sokubumba ngenxa yobukhulu babo obuncane, ukuqina okusheshayo, kanye nenani eliphakeme lokugeleza insimbi ephezulu. Izimbangela ezijwayelekile zifaka ukusebenza kokubumba okunganele kokubumba, ukuhlanganiswa okuphansi, amandla aphansi amanzi, ukuphindaphinda okunganele (okufana nokuqukethwe okuphansi kwe-sio Izinkinga zenqubo yokumodela: Ukuhlanganiswa kwendawo okungekho emkhakheni kwesihlabathi (njengamakona nezindawo zokuhlukanisa), ukuvuza kwesihlabathi okubangelwa yi-template / i-sand box ukugqoka (kanye nekhwalithi ephansi yokulungiswa kokubumba (njengamandla aphansi wezinto zokulungisa). Idizayini engenangqondo yohlelo lokuthulula: Izinga eliphezulu lokugeleza kwesiteshi sangaphakathi sokuthulula esisusa udonga, amandla abuthakathaka okuvinjwa okuvinjelwe kohlelo lokuthulula (ukuguquguquka okuthe xaxa ekushintshashintsheni okuphezulu.

2. Izinyathelo ezihlosiwe ezihlosiwe

a. Lungiselela ukusebenza kwesihlabathi sokubumba ukuze uthuthukise ukuhlanganiswa kanye nokufana: lungisa amapharamitha womshini wokubumbana (ngokuvamile, ukuphazamiseka kwesihlabathi sokubumba esigcwele (ngokuvamile) Ukwenza ngcono ukwakheka kwesihlabathi: isihlabathi sobumba: Ukungeza i-bentonite ephezulu ye-sodium based based basent (esikhundleni se-calcium esekwe) kuya ku-4-6% (accounting for isihlabathi sokuqala) ukuthuthukisa amandla okubopha; Lawula okuqukethwe okusebenzayo kwamalahle amalahle ngo-3-5% (kwakha i-carbon file anti sloiding sand), futhi inani lesihlabathi esivuselelekile kufanele libe ngu-50% (ukunciphisa uthuli nobucwebe kanye nobucwebe). Ukulawula umswakama: Ukuqukethwe komswakama kwesihlabathi esiluhlaza kufanele kugcinwe ku-3.5-4.0% ukugwema ukuba phezulu kakhulu (ukunciphisa amandla) noma okuphansi kakhulu (okukhulayo okuphansi kakhulu

b. Thuthukisa i-Modeling Press template kanye nokulungiswa kwebhokisi lesihlabathi Ukulawulwa kwekhwalithi yokulungiswa kokubumba: Gwema ukwenza isikhunta sinciphile kakhulu. Sebenzisa isihlabathi sokubumba esiphakeme (njengokungeza inani elincane lobumba) futhi kuhlanganiswe indawo yokulungisa. Kwenqatshelwe ukugcwalisa ngodaka ngentando.

c. Lungiselela ukwakheka kohlelo lokuthulula ukunciphisa izinga lokugeleza kanye nokuguguleka: Vumelana uhlelo oluvaliwe (F ngqo: 1 Ngeza i-buffering nokuhlunga: Faka izikhwama ze-buffering (njengezindandatho ze-ceramic) ezansi kwe-sprie, bese ubeka izihlungi ze-ceramic (ngosayizi we-pore we-0.5-1,0mm) endaweni engaphambili ye-spried is slue bese uhlupha i-slag. Ukuqhathanisa amapharamitha athululayo: Ukuthela izinga lokushisa Ukuthela ngejubane: ukuthulula okusheshayo nokuqhubekayo ukugwema ukuphazamiseka okubangela ukufakwa okubandayo noma izimbobo zesihlabathi sendawo.

d. Qinisa ukuvikelwa komhlaba kwesihlabathi futhi usebenzise izimbotshana ezivimbela umlilo Ngemuva kokumiswa, yakha ungqimba wedwa ukunciphisa ukungena kwensimbi encibilikisiwe. Ukuhlanganiswa kufanele kube umfaniswano futhi uvikele ukuqongelela (uma kungenjalo ukuphefumula okumpofu kwasendaweni kungadala ama-pores).

e. Lawula ikhwalithi nokuqina kwenqubo yensimbi ebiwe: Qinisekisa izinga lokushisa nokwakheka kwensimbi ebilisiwe ku-1550-1560 ℃ (ukugwema ukwakheka okuphansi okuphansi), futhi ugweme ukuqina okuqinile kokuqina), futhi ugweme ukuqina okuqinile kokuqina okubangelwa ukuphambuka. Ukwelashwa kweSlag: Ngaphambi kokuthela, hlanza i-slag engaphezulu yensimbi ebiwe noma usebenzise i-slag block ukotini / i-skimmer ukuvikela i-slag ukuthi ingeniswe ku-caversing yombumbane.

f. Ukuhlaziywa kwedatha kanye nokuqinisekiswa kwezimpawu zephutha: Bala indawo (eduzane nesango, indawo yokushintshana, kanye ne-morphology (eyodwa / eyodwa) yezitebele zesihlabathi (njengendawo ethile yendlela). Ukuhlolwa kokuqhathanisa: Ngemuva kokushintsha isilinganiso sesihlabathi noma ukuthela amapharamitha, ukukhiqizwa kwesimangalo esincane kwenziwa ukuqhathanisa isilinganiso semfucumfucu ye-SANV Hole futhi uqinisekise umphumela wokuthuthuka.

3. Isifinyezo

Izimbobo zesihlabathi ezindaweni ezinamalaka amancane zidinga ukuthi zilawulwe ngokuphelele "ngokuqinisa isihlabathi + ukuqina + ukuqina kwenqubo". Isihluthulelo ukuthuthukisa amandla nokumelana nomlilo kwesihlabathi sokubumba, qamba uhlelo olufanele lokuthulula ukunciphisa izinga lokugeleza, futhi lilawule ngokuqinile imininingwane nekhwalithi yensimbi ebilisiwe. Uma kungukubumba isihlabathi, inzuzo yayo ephezulu yamandla inganikezwa ukucatshangelwa okubaluleke kakhulu; Isihlabathi sobumba sidinga ukulungiswa okuhle kwe-bentonite, i-coal powder, kanye nomswakama, kuhlanganiswe nokuvikelwa kwe-coaging, ukunciphisa ngempumelelo amaphutha esihlabathi.
