Ulwakhiwo oludityanisiweyo lolwakhiwo lwesitovu sokuqhushumba, ukusuka ezantsi eziko ukuya kwinkqubo yolwakhiwo oluphezulu lomlilo ~

Isicwangciso sokwakha i-lining iyonke ye-blast furnace hot blast stove kwabelwana ngayo ngabavelisi bezitena eziphikisayo.

1. Ulwakhiwo lwegrouting emazantsi esitovu soqhushumbo olushushu:

Emva kokuba umzantsi wesitovu soqhushumbo oshushu ulinganiswe ngegrabile, udaka oluphikisayo kufuneka lusetyenziswe ukuvala umsantsa phakathi kwegrabile ukuqinisa ukutywinwa kunye nokomelela kwayo.

Inkqubo ye-grouting yile:

(1) Sebenzisa impompo yoxinzelelo oluphezulu ukucinezela eludakeni lwe-refractory, uyeke ukugrumba xa elinye izibuko lokugalela liphuma okanye intloko yombhobho werabha egayiweyo igqabhukile, kwaye uqalise ukugrumba kwizibuko le-grouting elilandelayo.

(2) Emva kokuba i-grouting epheleleyo iluyekile uxinzelelo, sebenzisa iplagi yomthi okanye umbhobho ovalekileyo ukuvala imbobo yokutsala. Emva kokuba yonke imibhobho ye-grouting igcwele i-grouting kwaye i-slurry ye-refractory iqinisiwe, susa umbhobho we-grouting, kwaye usebenzise ipleyiti yentsimbi ukutywina kunye nokuwelda i-orifice.

2. Ukwakhiwa kokugalelwa ezantsi kwesitovu esiqhumayo:

(1) Umyinge wezinto ezikhatywayo, ubungakanani bamanzi adityanisiweyo, kunye nokuxuba kunye nokwakhiwa kufuneka kuqhutywe ngokungqongqo ngokuhambelana nemiyalelo yomzi-mveliso yokuphosa.

(2) Ngethuba lenkqubo yokugalela, ukuphakama komphezulu kunye ne-flatness ye-castable kufuneka ihlolwe nangaliphi na ixesha. Kufuneka ilawulwe ngumgca wokuphakama ophawulwe kwikholomu ye-grate kunye negobolondo yesithando somlilo, kwaye igumbi lokutshisa kufuneka lilawulwe yimivalo yensimbi edibeneyo.

3. Ilayini yesitovu esiqhumayo:

Sebenzisa indlela yokucima ukukhupha umgca ophakathi komnqamlezo phakathi kwegrate kunye negumbi lokutsha, kwaye uphawule i-arc yodonga kunye nomgca oncedisayo wodonga lwegumbi lokutsha kunye nebhodi ye-arc.

(1) Ubume bodonga lweziko:

I-1) Beka ifayibha ye-ceramic ivakale kufutshane nomphezulu womgangatho wokutshiza womzimba wesithando somlilo, kunye nefiber evakalelwa kukuba kufuneka isondelene kunye, kwaye ubukhulu kufuneka buhlangabezane neemfuno zoyilo kunye nokwakhiwa.

2) Emva kokuba i-ceramic fiber ivakale ukwakhiwa kugqityiwe, qalisa ukwakha izitena zokugquma ukukhanya kwe-thermal, kwaye ekugqibeleni wakhe izitena ezinzima zobunzima bomgangatho osebenzayo.

3) Yakha udonga lwegumbi lokutsha kuqala, emva koko wakhe udonga lokuhlaziya, kwaye ekugqibeleni wakhe izitena zokukhangela, kwaye uphinde uphakamise ukwakhiwa phezulu kwinqanaba elifanayo.

(2) Ukwakhiwa kwezitena ezidibeneyo:

1) Okokuqala, khupha umphakamo osezantsi wesangqa esingaphandle sesitena sesemicircle esezantsi kwaye uyiphawule kwiqokobhe lesithando somlilo, kwaye ufakele intonga yevili embindini womngxuma ukulawula iradiyasi yobumeki.

2) Yakha izitena ezihlanganisiweyo zesiqingatha-sangqa esisezantsi kuqala, ukusuka kwindandatho yangaphandle ukuya kwindandatho yangaphakathi. Emva kokuba i-masonry esezantsi yesiqingatha-isangqa igqityiwe, misela amathaya e-semi-circular arch kwaye uqale ukwakha izitena ezihlanganisiweyo zesiqingatha sesangqa.

(3) Ulwakhiwo lwezitena ezitshixa:

1) Jonga umphakamo othe tyaba, umcaba kunye nendawo yomngxuma wegridi yegrate, njl., zonke kufuneka zihlangabezane neemfuno zoyilo kunye nolwakhiwo.

2) Emva kokuqinisekisa ukuba i-grate ifanelekile, khupha umgca wokuphakama kwezitena zokukhangela kwindonga enkulu kwaye uphawule umgca wegridi ye-masonry.

3) Emva kokuba izitena zokukhangela kumgangatho wokuqala zibekwe ngaphambili, khangela kwaye ulungise itafile yezitena zokukhangela kunye nezikhundla zegridi.

4) Ubungakanani bomdibaniso wokwandisa phakathi kwesitena sokukhangela kunye nodonga kufuneka lube ngu-20-25mm, kwaye ube ne-wedge eqinile kunye ne-wedge yokhuni.

5) Ngokweemfuno zokucwangciswa koyilo lwesibini kunye nesithathu sezitena ze-checker, imigca yegridi yamatye nayo imakishwe eludongeni. I-masonry kunye nokucwangciswa komgangatho wesine kufana nomgangatho wokuqala, kwaye ubungakanani obunqamlekileyo bemigangatho ephezulu nangaphantsi buvunyelwe. Ukutenxa akufanele kube ngaphezu kwe-3mm.

(4) Ubume bomgangatho wevault yesitovu soqhushumbo olushushu:

1) Qinisekisa umgca wobude bomgangatho wezitena eziphikisayo zomaleko wokuqala wecandelo le-cylindrical ngokokuphakama komgangatho ophantsi we-catenary arch foot joint joint. Qinisekisa ufanelekile.

2) Ubuso obuphezulu be-masonry kwindandatho ye-pallet iya kunyuswa nge-high-power castable.

3) Qinisekisa indawo yeziko lolawulo lwecandelo le-cylindrical ngokweziko lomngxuma ophezulu.

I-4) Emva kokuba igumbi lokutshisa kunye nezitena zokukhangela zakhiwe kwaye umgangatho uqinisekisiwe ukuba ufanelekile, qalisa ukufaka i-wheel plate yevili.

Sebenzisa i-rubber pad ukugubungela yonke i-regenerator, emva koko ususe i-plate yokuxhoma yegumbi elivuthayo, kwaye usebenzise ishedi yokukhusela ukugubungela ngokupheleleyo igumbi lokutsha. Faka i-shaft ejikelezayo ephakathi, uyilungise phezulu nasezantsi embindini womngxuma wesibhakabhaka kunye ne-rubber pad, faka i-template ye-radian, kwaye uphawule umgca wokuphakama kwezitena ebhodini.

5) Njengoko ukuphakama kwe-masonry yecandelo le-columnari ye-vault iphakama, ukuphakama kwe-scaffold erection kuphakanyiswe ngokuhambelanayo.

6) Xa ukwakhiwa kwecandelo le-columnari ye-vault, i-flatness ye-surface kufuneka ihlolwe nangaliphi na ixesha, kwaye iphutha elivumelekileyo lokulawula kufuneka lilungiswe ukuba libe ngaphantsi kwe-1mm ngexesha.

(5) Emva kokugqiba ukwakhiwa kwecandelo le-cylindrical ye-vault, qalisa ukwakha izitena ezidibeneyo. Ubume bezitena ezidibeneyo kufuneka ziqhutywe ukusuka phezulu ukuya phezulu. Izitena ezidibeneyo zibekwe kuqala kwaye emva koko kubekwe izitena ezidibeneyo.

1) Ukwakhiwa kwezitena ezidibeneyo ezisezantsi, izitena ezidibeneyo kufuneka zibekwe kuqala, kwaye iindawo zokwandiswa kufuneka zigcinwe ngokweemfuno zokwakha ngexesha lokwakha, kwaye iindawo ezidibeneyo kufuneka zizaliswe ngamacandelo okwandisa kwaye zilungiswe ngeengcingo zentsimbi. .

2) Umphezulu wobume bezitena ezidibeneyo kufuneka zihlolwe nangaliphi na ixesha lokuphakama kwayo, ukunyanzeliswa kunye ne-radius ye-masonry, kwaye akufuneki kubekho i-misalignment phenomenon, kwaye ukuguqulwa kwe-arc kufuneka kube lula.

3) Emva kokuba i-masonry yezitena ezidibeneyo zigqityiwe, qalisa ukwakha izitena ezidibeneyo ze-concave. Ekubeni esi sitena esihlangeneyo singasebenzisi udaka oluphikisayo kwi-masonry, i-wedges encinci yokhuni kufuneka isetyenziswe ukuyilungisa phambi kobume.

4) Xa ubeka umgca ophezulu odibeneyo, indlela yokumisa iyafana, kodwa akukho mfuneko yokugcinwa kwamalungu okwandisa.

(6) Xa umphezulu wevault ubekwe kuluhlu olumalunga ne-1.5～2.0m ukusuka kumngxuma ojikelezayo, qalisa ukuseta i-arch tayara imasonry ukwakha indawo ephezulu egobileyo.

Njengoko ukuphakama kwe-masonry ye-arc-shaped vault inyuka, ukuthambekela ngokuthe ngcembe kuya kuba mkhulu. Ngeli xesha, amakhadi e-hook kufuneka asetyenziselwe ukunyusa ukuzinza kwezitena ezinqambileyo ze-masonry.
