Castables feem ntau yog siv nyob rau hauv qhov chaw uas siab kub yog yooj yim rau hnav, vim castables yog ib hom khoom refractory, nws cov refractory zog muaj ntau mas, thiab cov ntseeg siab zoo dua, lub zog kuj zoo heev, rau qee qhov kev tsim kho ntau ntxiv Lub castable yog tseem zoo heev. Ntawm peb plaub lub caij, lub caij ntuj sov thiab lub caij ntuj no yog tshwj xeeb heev, ib qho yog kub heev, heev txhaws, thiab lwm yam yog heev txias. Peb tau tham nrog koj txog kev ceev faj txog txoj kev tsim cov castables rau lub caij ntuj sov. Niaj hnub no, cia peb tham txog dab tsi yuav tsum tau them nyiaj rau lub caij ntuj no?
Kev tsim kho ib puag ncig ntawm castables feem ntau yog nruab nrab ntawm 10 degrees Celsius thiab 30 degrees Celsius, tab sis lub caij ntuj no yog heev txias. Yog tias qhov ntsuas kub qis dua 5 degrees Celsius, cov nram qab no yuav tsum tau muab sau tseg.
(1) Cov kev ceev faj txog kev siv cov castables yuav tsum raug to taub meej meej, thiab qee tus yuav tsum nco ntsoov, nrog rau qee qhov sib xyaw, dej, thiab kev tu tsiaj, raws li cov lus saum toj no.
(2) Qhov kub ntawm tus nplawm yuav tsum tau muab sau tseg. Feem ntau, nws yog ib nrab ntawm 60 degrees Celsius thiab 80 degrees Celsius.
(3) Nws tau npaj siab tias cov castables raug muab tso rau qhov chaw kom tua cov ntoo lossis taws tua hluav taws, thiab qhov paub tsis ntev tshaj 12 teev. Dab tsi yuav tsum tau them sai sai rau thaum lub caij tsim cov pob zeb hauv lub caij ntuj no? Tom qab ua av, siv cov kev ntsuas kom haum, thiab khaws cia tshiab, qhov zoo dua yog nyob ntawm qhov chaw kom muaj qhov ntsuas tshaj 10 degrees.
(4) Lub sijhawm tsis ua haujlwm tsis yog tsawg dua 2 hnub, thiab cov khoom siv casting yog raug muab tso tawm pwm, thiab lub demoulding tsis cheem lub zog khawm. Tsis tas li ntawd, nco ntsoov tias tus nqi ntawm cov txij nkawm yuav tsum tau nqa tawm tom qab tus nto qaub ncaug.
(5) Nco ntsoov xyuam xim rau qhov cub kom sai li sai tau tom qab tu.
Kev tsim kho ntawm castables yuav tsum tau pom txawv ntawm lub caij ntuj no thiab lub caij ntuj sov, tiam sis nws yuav tsum tau sau tseg tias nws yog ncaj qha raws li kev ceev faj thiab tsis tuaj yeem nqa tawm raws li kev txhawj xeeb ntawm nws tus kheej. Yog tias ib yam ntawm cov txheej txheem saum toj no tsis yog lawm, nws tseem txais tos. Koj taw tes rau peb thiab peb yuav hloov ua lub sijhawm.
