Inkqubo yokulungiselela refractory castable

Inkqubo yokulungiselela i-refractory castables, ukongezwa kwe-fiber yensimbi kwi-samente-bonding castable inokuphucula ezinye iipropathi ze-castable: inokuphucula ukuqina kobudlelwane be-castable, ukuxhathisa ukutshatyalaliswa komatshini, ukuxhathisa ukothuka kwe-thermal, ukuchasana nokuqhekeka, kunye nokuxhatshazwa kwe-spalling. . Inokuthi ithintele i-shrinkage emva kokunyanga, ukomisa kunye nokunyanga ukushisa, ngaloo ndlela ukwandisa ubomi benkonzo ye-castable.

I-fiber yensimbi esetyenziselwa ukuqinisa i-refractory castable inobubanzi be-0.4-0.5mm kunye nobude be-25mm. Ubungakanani befiber yensimbi eyongeziweyo kwi-castable yi-1-4% (ubunzima). Ukuba i-fiber yensimbi ide kakhulu okanye isixa esongezelelweyo sininzi, i-fiber yensimbi ayiyi kuchithwa ngokulula ngexesha lokuphosa, kwaye umphumo ongcono wokuqiniswa awuyi kufumaneka; ukuba i-fiber yensimbi imfutshane kakhulu okanye isixa esongezelelweyo sincinci, umphumo wokuqiniswa awuyi kufezekiswa. Ngoko ke, ubude kunye nokongeza i-fiber yensimbi kufuneka ifaneleke.

I-fiber yensimbi inokuxutywa kumxube owomileyo, uze udibanise amanzi kwaye udibanise ngokulinganayo. Nangona kunjalo, ngokubanzi, umxube uxutywe ngamanzi kuqala, kwaye emva koko imicu yetsimbi ifafazwe ngokulinganayo kwi-castable, kwaye ixutywe. Oku akuvumeli nje ukuba umxube uvuthwe ngokufanayo, kodwa ugcina i-1/3 yexesha lokuxuba xa kuthelekiswa nokuxutywa kweentsinga zetsimbi kwizinto ezomileyo.

Ukwenza iifayili zetsimbi zihlakazwe ngokufanayo kwi-castable, iifayili zetsimbi kufuneka zihlakazwe ngokufanayo ngokungcangcazela okanye ukuhluza ngaphambi kokuba zongezwe kwi-castable. Emva kokuthululela kunye nokongeza i-fiber yensimbi, ukusebenza kuya kuncitshiswa, kodwa akukho manzi angaphezulu anokongezwa ukongeza, ngaphandle koko amandla okugqibela e-castable aya kuba engathandekiyo. Ngexesha lokubumba, i-vibrator ingasetyenziselwa ukungcangcazela ngaphandle, okanye intonga engcangcazelayo ingasetyenziselwa ukungcangcazela ngaphakathi kwemveliso, kunye neemveliso ezixineneyo nazo zinokufumaneka. Izixhobo zokhuni azinakusetyenziselwa ukugqiba umphezulu emva kokubunjwa, kuba iifayili zetsimbi ziya kungena kwisixhobo kwaye zonakalisa umgangatho wemveliso. Ukunyangwa kunye nokomisa iintambo zetsimbi eziqinisiweyo ziyafana neziqhelekileyo.
