Ukwakhiwa kolwelwesi oluhlanganisiwe lwesitofu esishisayo, kusukela phansi kwesithando somlilo kuya enqubweni yokwakha ulayini womlilo ophezulu ~

Uhlelo lokwakhiwa kolwelwesi oluphelele lwesitofu se-blast furnace luhlanganyelwa abakhiqizi bezitini abangabazi.

1. Ukwakhiwa kwe-grouting phansi kwesitofu esishisayo:

Ngemuva kokuthi isitofu sokuqhuma okushisayo silinganiswe ngohlalwane, udaka oluphikisayo kufanele lusetshenziselwe ukugcwalisa igebe phakathi kwetshe ukuze kuthuthukiswe ukuvaleka kwalo namandla.

Inqubo ye-grouting ithi:

(1) Sebenzisa iphampu enengcindezi ephezulu ukuze ucindezele odakeni oluyimibili, yeka ukuhluza lapho enye imbobo yokukhipha i-grout iphuma noma ikhanda lepayipi lenjoloba eliqhumayo liqhuma, bese uqala ukuhluza esikhumulweni esilandelayo.

(2) Ngemuva kokuthi i-grouting egcwele imise ukucindezela, sebenzisa ipulaki yokhuni noma ukuvaleka kwepayipi ukuze uvale imbobo yokukhipha. Ngemuva kokuthi wonke amapayipi e-grouting agcwele i-grouting futhi i-refractory slurry iyaqina, susa ipayipi le-grouting, bese usebenzisa i-steel plate ukuvala nokushisela i-orifice.

2. Ukwakhiwa kokuphonswa phansi kwesitofu esishisayo:

(1) Ingxenye yezinto ezikhandwayo, inani lamanzi elengeziwe, kanye nokuxutshwa nokwakhiwa kufanele kwenziwe ngokuqinile ngokuhambisana neziyalezo zasefekthri zalokhu okugaywayo.

(2) Phakathi nenqubo yokuthulula, ukuphakama kobuso kanye nokucaba kwe-castable kufanele kuhlolwe nganoma yisiphi isikhathi. Kufanele ilawulwe umugqa wokuphakama omakwe kukholomu ye-grate kanye negobolondo lesithando somlilo, futhi igumbi lomlilo kufanele lilawulwe ngamabha ensimbi ashiselwe.

3. Ulwelwesi lwesitofu se-hot blast:

Sebenzisa indlela ye-offset ukuze ukhiphe umugqa ophakathi kwesiphambano phakathi kwe-grate negumbi elivuthayo, bese umaka i-arc yodonga kanye nomugqa osizayo wodonga lwegumbi lomlilo ngebhodi le-arc.

(1) Udonga lwamatshe omlilo:

I-1) Beka i-ceramic fibre ezwakele eduze nobuso bongqimba lwesifutho somzimba wesithando somlilo, futhi i-fiber ezwakalayo kufanele isondelene, futhi ubukhulu kufanele buhlangabezane nezidingo zokuklama nezokwakha.

2) Ngemva kokuba i-ceramic fibre ezwakele ukwakhiwa sekuqediwe, qala ukwakha izitini zokushisa ezishisayo ezinesisindo esincane, futhi ekugcineni wakhe izitini ezisindayo ezinesisindo esinzima songqimba olusebenzayo.

I-3) Yakha udonga lwegumbi lomlilo kuqala, bese wakha udonga lwe-regenerator, futhi ekugcineni wakhe izitini zokuhlola, bese uphinda ukwakhiwa okuya phezulu kuze kufike ekuphakameni okufanayo.

(2) Ukwakhiwa kwezitini okuhlanganisiwe:

1) Okokuqala, khipha ukuphakama okungaphansi kwesitini esiyinhlanganisela yendandatho yangaphandle yengxenye engezansi yesiyingi bese uyimaka egobolondweni lesithando somlilo, bese ufaka induku yesondo emaphakathi nendawo embobeni ukuze ulawule indawo engaba ngamatshe.

2) Yakha izitini eziyinhlanganisela eyingxenye yendandatho engezansi kuqala, ukusuka eringini yangaphandle kuye engaphakathi. Ngemva kokuphothulwa kwe-masonry engaphansi kwesigamu esiyindilinga, setha amathayi angama-arch angama-semi-circular futhi uqale ukwakha izitini ezihlanganisiwe zengxenye engaphezulu.

(3) Ukwakhiwa kwezitini:

1) Hlola ukuphakama okuvundlile, ukucaba kanye nendawo yembobo yegridi ye-grate, njll., konke kufanele kuhlangabezane nezidingo zokuklama nezokwakha.

I-2) Ngemva kokuqinisekisa ukuthi i-grate ifanelekile, khipha umugqa wokuphakama kwezitini zezitini odongeni olukhulu bese uphawula umugqa wegridi yamatshe.

I-3) Ngemuva kokuthi izitini zokuhlola esitezi sokuqala zibekwe ngaphambili, hlola futhi ulungise ithebula lezitini zokuhlola kanye nezikhundla zegridi.

4) Ubukhulu bejoyinti lokunweba phakathi kwesitini sokuhlola nodonga kufanele bube ngu-20-25mm, futhi buqine nge-wedge yokhuni.

I-5) Ngokwezidingo zokuhlelwa kokuklama kwezingqimba zesibili nezesithathu zezitini zokuhlola, imigqa yegridi yamatshe nayo imakwe odongeni. I-masonry kanye nokuhlelwa kwesendlalelo sesine kufana nesendlalelo sokuqala, futhi usayizi ophazamisayo wezingqimba ezingaphezulu nezingaphansi zivunyelwe. Ukuchezuka akufanele kube kukhulu kuno-3mm.

(4) Imasonry yevault yesitofu se-hot blast:

1) Nquma umugqa wobude wongqimba lwezitini eziphikisayo zongqimba lokuqala lwesigaba se-cylindrical ngokusho kokuphakama kwendawo engezansi yesitini esihlangene se-catenary arch foot. Qinisekisa ukufaneleka.

I-2) Ingaphezulu le-masonry kwindandatho ye-pallet kufanele ilinganiswe nge-high-power castable.

I-3) Nquma isikhundla sesikhungo sokulawula sesigaba se-cylindrical ngokusho kwesikhungo sembobo ephezulu.

I-4) Ngemuva kokuthi ikamelo elivuthayo nezitini zokuhlola zakhiwe futhi ikhwalithi iqinisekisiwe ukuthi ifanelekile, qala ukufaka ipuleti lesondo eliphakathi.

Sebenzisa i-rubber pad ukuze umboze sonke i-regenerator, bese ususa ipuleti elilengayo legumbi elivuthayo, bese usebenzisa ishede elivikelayo ukuze uvale ngokuphelele igumbi elivuthayo. Faka i-shaft ejikelezayo emaphakathi, uyilungise phezulu naphansi phakathi nendawo yembobo yesibhakabhaka kanye nephedi yenjoloba, faka isifanekiso se-radian, bese umaka umugqa wobude besitini ebhodini.

5) Njengoba ukuphakama kwe-masonry kwesigaba sekholomu ye-vault kuphakama, ukuphakama kwe-scaffold erection kuyaphakanyiswa ngokuhambisana.

I-6) Uma wakha ingxenye yekholomu ye-vault, ukukhanya kwendawo kufanele kuhlolwe nganoma yisiphi isikhathi, futhi iphutha elivumelekile lokulawula kufanele lilungiswe libe ngaphansi kuka-1mm ngesikhathi.

(5) Ngemva kokuqeda ukwakhiwa kwengxenye ye-cylindrical ye-vault, qala ukwakha izitini ezihlangene. Ukwakhiwa kwezitini ezihlangene kufanele kwenziwe kusukela phansi kuya phezulu. Izitini ezihlangene zibekwa kuqala bese kubekwa izitini ezihlangene.

1) Ngokwakhiwa kwezitini ezihlangene eziphansi, izitini ezihlangene kufanele zibekwe kuqala, futhi amalunga okunweba kufanele agcinwe ngokuvumelana nezidingo zokwakha ngesikhathi sokwakhiwa kwamatshe, futhi amalunga kufanele agcwaliswe amalunga okunweba futhi ahlanganiswe nezintambo zensimbi. .

2) Ingaphezulu le-masonry yezitini ezihlangene ze-convex kufanele ihlolwe nganoma yisiphi isikhathi ngokuphakama kwayo, ukucaba kanye ne-radius ye-masonry, futhi akufanele kube khona ukungahambi kahle, futhi ukuguqulwa kwe-arc kufanele kube bushelelezi.

3) Ngemuva kokuthi ukwakhiwa kwezitini ezihlangene ze-convex sekuqediwe, qala ukwakha izitini ezihlangene ze-concave. Njengoba lesi sitini esihlangene singasebenzisi udaka oluphikisayo ekwenzeni ama-masonry, ama-wedges amancane okhuni kufanele asetshenziselwe ukulungisa ngaphambi kokwakhiwa kwamatshe.

I-4) Uma ubeka ungqimba olungaphezulu oluhlangene, indlela yokumisa iyafana, kodwa asikho isidingo sokugcina amalunga okunweba.

(6) Uma i-vault top ibekwe ebangeni elingama-1.5–2.0m ukusuka embobeni ephithizelayo, qala ukusetha i-arch tire masonry ukuze wakhe indawo engaphezulu egobile.

Njengoba ukuphakama kwe-masonry ye-vault emise okwe-arc kuphakama, ukuthambekela kuya ngokuya kuba kukhudlwana. Ngalesi sikhathi, amakhadi e-hook kufanele asetshenziselwe ukwandisa ukuzinza kwezitini eziphikisayo zamatshe.
