Ukusetyenziswa kwemveliso

Imibandela efuna ingqalelo

● Yomisa ukuxuba kuqala, uze emva koko ube manzi udibanise namanzi.Yongeza amanzi aneleyo okuxutywa okumanzi ngexesha elinye.Musa ukufaka amanzi ngokuthanda kwakho.

● Ixesha lokuxuba lixhomekeke kwimeko yokuxuba kwaye ayiyi kuba ngaphantsi kwexesha elifunekayo lokuxuba.Kuphela emva kokuba zonke izinto ezixutywe ngokupheleleyo zinokufikelela umphumo wokusetyenziswa okuqhelekileyo.

● Ukuba akukho mxube okanye iimeko azivumelekanga, xa ukuxuba ngesandla kufuneka, ixesha lokuxuba liya kwandiswa ukuze kuqinisekiswe ukuba izinto zixutywe ngokupheleleyo.

● Nceda usebenzise izinto ezixutyiweyo kwimizuzu engama-30.Emva kwemizuzu engama-30, ukusebenza kwezinto eziphathekayo kuyatshintsha kwaye akunakusetyenziswa.Nceda ulahle intsalela.

Ukusetyenziswa kunye nethamo

● Vula ipakethe, uthele izinto kunye ne-admixtures kwi-mixer, umxube owomileyo kwaye ugxobhoze imizuzu eyi-1-3 ukuze udibanise ngokupheleleyo.

● Yongeza amanzi aneleyo (malunga ne-10% yamanzi okusela okusela) ngexesha elinye, ungafaki amanzi ngokuthanda kwakho, umxube omanzi imizuzu emi-3-5, kwaye udibanise ngokupheleleyo.

Ezi ziqhagamshelo ezine zilandelayo kufuneka ziqwalaselwe ekusetyenzisweni kwe-refractory castable, oko kukuthi ukuxuba, ukugalela, ukunyanga kunye nokubhaka.

Nayiphi na ingxaki nakweyiphi na ikhonkco inokukhokelela ekuthotyweni kwemveliso okanye ekusebenziseni ukungaphumeleli.

Ukuxuba

Ukuxuba kuhlulwe kumxube womatshini kunye nokuxuba ngesandla.Okwangoku, i-mixers enyanzelekileyo okanye i-mortar isetyenziswe kwishishini ukuxuba izinto, kwaye ukuxuba ngesandla akusetyenziswanga Izixhobo kunye nezixhobo: ukunyanzeliswa okanye umxube wodaka, iibhakethi, izikali, i-vibrators, ifosholo zesixhobo, iitroli, njl.

Ukusetyenziswa kwamanzi okwakhiwa kusekelwe kusetyenziso lwamanzi olubonakaliswe kwiphepha lokuhlola umgangatho webhetshi yeemveliso, kwaye iphunyezwe ngokungqongqo ngokuhambelana nemigangatho yokufezekisa umlinganiselo ochanekileyo.

Ukuxuba: Xuba yomise kuqala kwaye umanzi.Beka izinto ezininzi kwi-mixer kwaye uyomise imizuzu eyi-1-3 ngokulandelelana kwesikhwama esikhulu kuqala kwaye emva koko isikhwama esincinci ukuze sidibanise ngokulinganayo.Ubunzima bomxube ngamnye bunqunywe ngokuhambelana noomatshini kunye nomthamo wokwakha;ngokobunzima bezinto eziphathekayo, amanzi afunekayo kumxube ngamnye alinganiswe ngokuchanekileyo ngokusetyenziswa kwamanzi achaziweyo, ongezwe kwizinto ezomileyo ezixutywe ngokulinganayo, kwaye avuselelwe ngokupheleleyo.Ixesha alikho ngaphantsi kwe-3min, ukwenzela ukuba ibe ne-fluidity efanelekileyo, kwaye ke izinto eziphathekayo zinokukhutshwa ukuze zigalelwe.

Ukugalela

Ngaphambi kokuba izinto zokugalela zakhiwe, kuyimfuneko ukujonga ukuba iihange ziqiniswe ngokuqinileyo, kwaye izikhonkwane ezinokumelana nokushisa kufuneka zifakwe kwiindawo ezingaphezulu kwe-500C.Umphezulu we-ankile kufuneka upeyintwe ngepeyinti eyi-0. 5-1mm eshinyeneyo okanye isongwe ngeteyiphu yeplastiki ukuze ikhusele amandla okwandisa emva kokufudumeza kunye nokususa inkunkuma ekubumbeni.

I-castable esanda kuxutywa kufuneka igalelwe ngokukhawuleza, ngokubanzi ngaphakathi kwe-20min.Thela i-mixed castable kwi-mold, kwaye ufake i-vibrator kwi-vibrator ngexesha, kwaye i-vibrator kufuneka ifane.Xa umphezulu we-castable i-slurried, iibhubhu ziyakhutshwa.Xa umphezulu uphazamisekile, intonga yokungcangcazela iyashukunyiswa, kwaye isantya esihambayo si-1-2m / min.Xa intonga yokungcangcazela ikhutshwa, isantya siyacotha.

Ngaphambi kokuba ukuqina kugqitywe emva kokugalelwa, ubushushu bendawo kufuneka bugcinwe bungaphezulu kwe-10C(10-30.C).Ukuba iqondo lobushushu lendawo lingaphantsi kwe-0'C, kufuneka kuthathwe amanyathelo okufudumeza okuhambelanayo kunye nokugcina ubushushu, kungenjalo kuya kubangela ukuncipha kwaye kukhokelele ekuthotyweni kwemveliso.

Isondlo

Izixhobo eziphambili ezisetyenzisiweyo ziyifilimu yeplastiki ye-polyethylene, iingxowa ze-straw, njl. ukusebenza kwemveliso kuya kuncitshiswa.

Emva kokuba i-castable iqiniswe, kuyimfuneko ukugubungela ngokukhawuleza umphezulu womzimba wokwakha kunye nefilimu yeplastiki ye-polyethylene, kwaye uyigqume ngengxowa yengca emanzi ukukhusela ukuvela kwamanzi kunye nokukhuthaza ukusebenza kwesamente Emva kokuqina, akuvumelekanga ukubetha kunye nokungcangcazela ngaphakathi komnye. usuku.Ngokwemeko yokuqina, inokudilizwa emva kweeyure ezingama-24-30 zokuqina.

Emva kokudilizwa, kufuneka igcinwe iintsuku ezimbini njengoko kuyimfuneko, kwaye ifilimu yeplastiki ye-polyethylene kunye neengxowa ze-straw ezimanzi kufuneka zongezwe ngexesha lokugcinwa.Emva kweentsuku ezintathu zokunyanga, susa ifilimu yeplastiki kunye nesikhwama somququ.Vumela umzimba oqinileyo ukuba wome ngokwemvelo emoyeni ngosuku ngaphambi kokubhaka.

Ukubhaka

Ukubhaka likhonkco lokugqibela ekusetyenzisweni kwee-castables.Ekubeni umzimba wokuphosa uxinene, akuvumelekanga ngokupheleleyo ukutshisa ngokukhawuleza ngexesha lokubhaka, kungenjalo kuya kubangela ingozi yokuqhekeka.
