Fireclay refractory castable oo lagu daray walxaha budada alumina, dhoobada jilicsan, marka loo eego saamiga isku dhafka isku dhafka ah ee isku dhafka ah in ka badan 5 daqiiqo iyo qasiyaha, guud ahaan, heerkulka la isticmaalayo waa 1300-1450 ℃. Kabka dab-damiska waxaa inta badan loo adeegsadaa dahaarka foornada kululaynta birta, foornada kulaylka, kuleyliyaha, foornada shaft, aagga kuleylka preheating ee foornada wareegta. Sidoo kale kabka dhoobada dabka refractory ayaa si weyn loogu isticmaalaa noocyada kala duwan ee dahaarka foornada. sida kuleyliyaha, foornada qarxinta shooladda kulul, foornada kululaynta, foornada dhoobada, foornada rotary sibidhka, darbiga warshad koronto iwm.
Xulashada maaddooyinka waa hab aad muhiim u ah, taas oo ah isku xirka muhiimka ah si loo hubiyo wax soo saarka dhoobada dhoobada. Marka loo eego qaacidada iyo isticmaalka, alaabada shubka dhoobada refractory ee ku habboon, budada, binder iyo wax lagu daro ayaa la doortaa.
Dufcaddu waa in lagu baadho agabka ceeriin ee la xushay si waafaqsan darajada iyadoo loo eegayo qaacidada, oo si adag loo xakameeyo cabbirka wadarta iyo budada.
Markaad walaaqdo, isku qas budada si siman, ka dibna isku dar wadarta guud si siman.Ku dar isku dar ah isku darka oo mar kale isku qas. Xakamee wakhtiga wax kicinta.
Ku rid alaabta dhoobada ah ee la walaaqay bacda tonka, oo ku qalabee wax lagu daro iyo xiraha, ka dibna xirmo.
Qalabka baakadaha lagu shubo waa in lagu kaydiyaa bakhaarka, taariikhdana waa in la calaamadiyaa oo aan biyuhu lahayn
Si adag u xakamee isticmaalka biyaha marka aad samaynayso dhoobo ku shubaya goobta.
Inta lagu jiro dhismaha, fiiro gaar ah u yeelo waqtiga gariirka iyo habka gariir.
Xakamee habka dubista ka dib marka la shubo, mamnuuc kuleyl badan oo ka hortag dildilaaca jirka dhismaha.

Qalab-celinta dabka waxaa inta badan loo adeegsadaa dahaarka foornada kululaynta birta, foornada kulaylka, kuleyliyaha, foornada shaft, aagga kulaylka ee foornada wareegta. Sidoo kale kabka dhoobada dabka refractory ayaa si weyn loogu isticmaalaa noocyada kala duwan ee dahaarka foornada. sida kuleyliyaha, foornada qaraxa shooladda kulul, foornada kuleylka, foornada dhoobada, foornada rotary sibidhka, darbiga warshad koronto.
Warshada refractory ee RS oo ah warshad farsamayaqaan ah oo soo saarta kabka dib-u-celinta dabka ee Shiinaha, waxay leedahay faa'iidooyin badan oo tartan ah suuqa. Haddii aad rabto inaad kasbato kabka dab-damiska, ama aad hayso su'aalo ku saabsan kabka dhoobada dab-damiska ee ku saabsan tilmaamayaasha jirka iyo kiimikada, fadlan nala soo xiriir bilaash, waxaan ku siin doonaa tayo sare leh oo kabka ah dhoobada dabka.
