Ukwakhiwa kwee-castables ezichasene nokushisa okuphezulu kuqhutyelwa yindlela yokugubha, esetyenziswa ngokubanzi, kubandakanywa nokwakhiwa kwezixhobo zokugubha ezomileyo.Ngaba uyayazi indlela echanekileyo yokusetyenziswa kwezinto ezilahlwayo ezinobushushu obuphezulu?
1. Ukulungiswa ngaphambi kokwakhiwa
Ngokweemfuno zomda woyilo, umgangatho wokwakhiwa kwenkqubo yangaphambili iya kujongwa kwaye yamkelwe, kwaye indawo yokwakha yebhoyila iya kucocwa.
Umxube onyanzeliswayo, i-plug-in vibrator, i-handcart kunye nabanye oomatshini kunye nezixhobo zithuthelwa kwindawo yokwakhiwa kwebhoyili, efakwe endaweni, kwaye uvavanyo oluqhutywa luqhelekileyo.Itheyibhile ilandelayo ibonisa iimpawu zobugcisa ze-plug-in vibrator.Kufuneka kucaciswe ukuba intonga enyanzeliswayo yokungcangcazela esetyenziselwa umxube kufuneka ibe yefrikhwensi ephezulu kwaye kufuneka kubekho iindawo ezaneleyo.
I-formwork iya kuba namandla okwaneleyo kunye nokuqina, nokuba ihanjiswe kwindawo yokwakhiwa kwebhoyila;Amandla okukhanyisa axhunyiwe, kwaye amanzi acocekileyo axhunyiwe phambi komxube.
Ii-castables ezikwazi ukumelana nobushushu zivame ukupakishwa kwiingxowa.Izinto ezifana nezitena ze-anchor, izihlanganisi, izitena ezikhuselayo zokugquma, iibhodi ze-calcium silicate, iibhodi ze-asbestos, izitena zodongwe eziphikisayo kunye nezitena zokutshisa kufuneka zihanjiswe kwindawo yokwakhiwa kwebhoyili nangaliphi na ixesha njengoko kufuneka.
Xa i-agent ebophelelayo yeekhemikhali isetyenzisiweyo, ukuxinwa kwayo okanye ukuxinana kuya kulungiswa kwangaphambili kwaye kuhanjiswe kwindawo yokwakhiwa kwebhoyila ukuze isetyenziswe.Ngaphambi kokusetyenziswa, iya kuxutywa ngokulinganayo kwakhona.
2. Ukuqinisekiswa komxube wokwakha
Ngaphambi kokwakhiwa, i-bagged ephezulu yokushisa i-castables kunye nezongezo zabo ziya kuthatyathwa kwaye zivavanywe ngokweemfuno zemizobo yoyilo okanye imiyalelo yomenzi, kwaye iipropati eziphambili ziya kuhlolwa.Xa ubushushu obuphezulu obunokulahlwa busilela ukuhlangabezana neemfuno zoyilo, imathiriyeli iya kutshintshwa kwangoko kangangoko ngaphandle kokungakhathali.Ngoko ke, lo msebenzi ubaluleke kakhulu.Ekubeni ukuthengwa kwe-castables ephezulu yokushisa, kufuneka kuhlawulwe ingqalelo kwiimpawu zabo zokusebenza.Iimveliso ezifanelekileyo ziya kusetyenziswa njengenxalenye yomxube wokwakhiwa kwendawo yokwakha yebhoyila ngokwemiqathango yendawo yokwakhiwa kwebhoyila kunye nexesha lokugcinwa kwezinto.
3. Ukubeka kunye nefom ye-thermal insulation layer
Kulwakhiwo lokungcangcazela kwezinto ezilahlwayo ezinobushushu obuphezulu, lo msebenzi ukwangowokulungiselela ukwakhiwa.
Phambi kolwakhiwo lobushushu eliphezulu ukumelana castable eludongeni eziko, okokuqala wabeka ibhodi asbestos, ibhodi calcium silicate okanye ifayibha refractory waziva, ufakele izihlanganisi metal, indawo izitena iankile, kwaye okwesibini walala insulatory izitena refractory okanye ugalele ukukhanya ubushushu obuphezulu castables ukumelana;Okwesithathu kukwenza umsebenzi owenziweyo.Umphezulu osebenzayo we-formwork uya kufakwa ngeoli okanye izitikha kuqala, kwaye emva koko usondele kwisiphelo sobuso besitena se-anchor ukuxhasa.Ubude be-formwork eyakhiwe ngexesha ngalinye yi-600 ~ 1000mm, ukwenzela ukuba kube lula ukulayisha kunye nokubunjwa kwe-vibration.Kwimeko ye-fetus membrane, i-membrane ye-fetus iya kuxhaswa kuqala, kwaye emva koko i-formwork iya kwakhiwa.Umphezulu we-thermal insulation layer uya kugalelwa ngefilimu yeplastiki ukuthintela ukufunxa amanzi kunye nokuchaphazela ukusebenza kwe-castable.
Xa udonga lwesithando somlilo luphezulu, i-insulation layer kufuneka yakhiwe ngokwemigangatho yokuthintela ukuthululwa kwe-insulation layer xa izinto zokugalela zingcangcazela.
Ngexesha lokwakhiwa kwe-refractory castable furnace top, yonke ifomwork iya kumiswa ngokuqinileyo kwaye emva koko ifakwe i-oyile ngokweemfuno zomda woyilo;Emva koko xhoma izitena zokuxhoma kwintsimbi yokuphakamisa kunye nezixhumi zetsimbi.Ezinye iziqhagamshelo kufuneka zilungiswe ngeentambo zokhuni, ngelixa ezinye azidingi ukulungiswa.Izitena ezijingayo ziya kubekwa ngokuthe nkqo kunye nobuso obusebenzayo belinen yesithando somlilo.Umgama phakathi kobuso besiphelo esisezantsi kunye nobuso be-formwork ngu-0 ~ 10mm, kwaye isiphelo sobuso bezitena ezixhonywe ngamanqaku angaphezu kwama-60 epesenti ziya kuqhagamshelana ne-formwork face.Xa isithuba singaphezu kwe-10mm, izihlanganisi zentsimbi ziya kulungelelaniswa ukuhlangabezana neemfuno.Kwimeko yemingxuma, i-membrane iya kufakwa ngokuqinileyo, kwaye emva koko i-formwork iya kwakhiwa.
4. Ukuxuba
Umxubi osisinyanzelo uyakusetyenziselwa ukuxuba.Xa ubungakanani bezinto eziphathekayo buncinci, bunokuxutywa ngesandla.Ukuxutywa kwee-castables ezichasene nobushushu obuphezulu kuyahluka ngenxa yeentlobo ezahlukeneyo;Kumthwalo wengxowa okanye iaggregatory refractory kunye nesamente, imposiso evumelekileyo yi ± 1.0 yepesenti yamanqaku, impazamo evumelekileyo yezongezo yi ± 0.5 yepesenti yamanqaku, impazamo evumelekileyo kwi-hydrated liquid binder yi-± 0.5 yepesenti yamanqaku, kwaye idosi yezongezo kufuneka ichaneke. ;Zonke iintlobo zemathiriyeli ekrwada ziyakugalelwa kumxubi emva kobunzima ngaphandle kokushiya okanye ukongezwa.
Ukuxutywa kwezinto zokulahla ezinobushushu obuphezulu ezifana nesamente, ukudibanisa ngodongwe kunye nochungechunge lwesamente ephantsi, kuqala ugalele ukulayishwa kwengxowa, izongezo kunye nezongezelelo kwi-mixer ukwenza izinto ezininzi, kwaye zome zixube i-1.0min, uze udibanise amanzi zixube ezimanzi kwi-3-5 min emva kokuba zifana.Zikhuphe emva kokuba umbala wezinto eziphathekayo ufana.Emva koko ihanjiswa entendeni kwaye ilaphu liqalisiwe.
Ukuxuba i-sodium silicate high-temperature resistant castable, izinto eziluhlaza okanye iigranules zingafakwa kwi-mixer yokuxuba okomileyo, emva koko isisombululo se-sodium silicate songezwa ukuxuba okumanzi.Emva kokuba i-granules ihlanganiswe nge-sodium silicate, i-powder refractory kunye nezinye izinto zongezwa.Ukuxuba okumanzi malunga ne-5min, kwaye ke izinto eziphathekayo zinokukhutshwa ukuze zisetyenziswe;Ukuba izinto ezomileyo zixutywe kunye, zigalele kwi-mixer yokuxuba okomileyo kwi-1.0min, yongeza i-2/3 isisombululo se-sodium silicate sokuxuba okumanzi kwi-2-3min, kwaye ungeze i-agent eseleyo yokubopha ukuxuba okumanzi kwi-2-3min, emva koko. izixhobo zingasetyenziswa.Ukuxutywa kwe-resin kunye nekhabhoni equlethe ubushushu obuphezulu obunokulahlwa kuyafana nale.
Ukuxutywa kwezinto ezinokumelana nobushushu obuphezulu njenge-phosphoric acid kunye ne-phosphate, qala ugalele izinto ezomileyo kwi-mixer yokuxuba okomileyo kwi-1.0min, yongeza malunga ne-3/5 ye-binder yokuxuba okumanzi kwi-2-3 min, emva koko ukhuphe izinto. , yithuthele kwindawo echongiweyo yokupakisha, yimboze ngokuqinileyo ngefilimu yeplastiki, kwaye ubambe izinto ezingaphezulu kwe-16h.Izinto ezibanjiweyo kunye ne-accelerator ye-coagulant iya kulinganiswa kwaye igalelwe kwi-mixer yokuxuba okwesibini, kwaye i-binder eseleyo iya kongezwa ukuxuba okumanzi kwi-2-4min ngaphambi kokusetyenziswa.
Ngexesha lokuxutywa kwezixhobo zokulahla ubushushu obuphezulu, ukuba izongezo ezinje ngefiber enganyangekiyo kubushushu, ifayibha enganyangekiyo emlilweni kunye nefiber ephilayo kufuneka yongezwe kwizinto eziphoswayo, kufuneka zisasazeke ngokuqhubekayo kwizinto ezixutywayo zomxube ngexesha lokuxutywa okumanzi kwee-castables. .Zifanele zihlakazeke kwaye zixutywe ngexesha elifanayo, kwaye akufanele zifakwe kwi-mixer ngamaqela.
Emva kokuba umxube ukhutshwe kwi-mixer, ukuba yomile kakhulu, incinci kakhulu okanye ingenayo into ethile, izinto eziphathekayo ziyakulahlwa kwaye aziyi kuphinda zongezwe;Umxube okhutshwe kwi-mixer uya kuba phakathi kwe-0.5 ~ 1.0h.
