Ingakanani ithani elingu-1 le-refractory castable?

Ingakanani i-castable ngethani? Lona umbuzo amakhasimende akhathazeke kakhulu ngawo futhi avame ukuxhumana nomkhiqizi ophonsa. Kunezinhlobo eziningi zama-castable, okuyizinto eziphikisayo ezingabunjwanga kuma-refractories. Kunezinhlobo eziningi zezinto zokusetshenziswa, futhi amanani emikhiqizo ayahluka kakhulu. Umhleli olandelayo uqoqa okuqukethwe okuhlobene mayelana nenani lama-castable, futhi abangani abanentshisekelo bangaqonda Phansi.

Ngokwezingxenye ezihlukene kanye nezinhloso zehhani ngalinye, okuphonswayo kuhlukaniswe ngezinhlobo eziningi. Izigqoko eziqinile eziqinile ezingagqoki ziqiniswa yi-corundum, i-fiber yensimbi, ne-fiber yensimbi; ama-castable amelana nokushisa okuphezulu ahlanganisa i-tap ditch kanye ne-ladle; kanye ne-heat-insulating light-weight kanye ne-heat-insulating castables.

i-castable, eyaziwa nangokuthi i-refractory castable, iwuhlobo lwempahla eyimbudumbudu kanye nempuphu eyenziwe ngezinto eziphikisayo inani elingeziwe le-binder. Inoketshezi oluphezulu futhi iyinto ephikisayo engamile eyakhiwe ngokusakazwa. Uma kuqhathaniswa nezinye izinto eziphikisayo ezingakabunjwa, i-binder kanye nomswakama okuqukethwe kuphezulu, futhi uketshezi lungcono. Ngakho-ke, i-castable inezinhlobonhlobo zezinhlelo zokusebenza. Izinto kanye nama-binder asetshenzisiwe angakhethwa ngokuya ngemibandela yokusetshenziswa. Ingathululelwa ngqo olayini ukuze isetshenziswe, noma ingasetshenziswa njengebhlokhi eseyakhiwe ngokuthela noma ngokuthepha.

Umjikelezo wokukhiqiza wama-castable aphikisayo ngokuvamile mfushane kunalowo wezitini eziphikisayo zento efanayo, ngakho-ke ukuthengiswa kwama-castables aphikisayo kukhulu kakhulu, ngakho-ke ukuthi ingakanani i-castable ithoni ibe yindaba ebaluleke kakhulu, kodwa asikwazi ukuyilandela ngokungaboni. . Intengo ephansi kanye nekhwalithi kuwumgomo wemboni ye-refractory. I-castable inezidingo eziphakeme kakhulu zokwakheka, ubukhulu bezinhlayiyana bunengqondo, futhi uhlobo kanye nenani lezithasiselo zinomthelela osobala kakhulu ku-castable. Ukwakhiwa kwe-castable kanye ne-ovini kufanele kwenziwe ngokuhambisana ngokuqinile nezidingo, ukuze kuqinisekiswe impilo yesevisi ye-castable.

Ngenxa yochungechunge lwezici zenhloso njengendawo yokwakhiwa kanye nokuqhubeka kwephrojekthi, ezinye izithasiselo noma ezinye izinto zingangezwa kokuphonswayo ukuze kuhlangatshezwane nezidingo. Isibonelo, amafayibha ensimbi angangeni ekushiseni angengezwa ku-castable ukuze kuthuthukiswe amandla okuphonswa. Amanye ama-accelerator angengezwa ukuze kusheshiswe isikhathi sokusetha sokuqala sokuphonswa. Ezimbonini ze-electrolytic aluminium kanye ne-aluminium alloy, izinto ezifakwayo zidinga ukungeza izinto ezithile ezimelana nokuguguleka kwamanzi e-aluminium ukuze kunwetshwe isikhathi sokusebenza kwezinsimbi. Ngemuva kokuthi ezinye izinto ezinjengama-nitrides zengezwe kuma-castables, ukusebenza okungama-stick of the castables kuthuthukiswa kakhulu.

Ngokuthuthukiswa kwezinto eziphikisayo, ama-castable anezici ezihlukahlukene ezivelele athuthukisiwe futhi akhuthazwa. Uma udinga ama-castable, ungaxhumana nomkhiqizi wethu ukuze uthole ikhotheshini enemininingwane firstfurnace@gmil.com
