Tignoolajiyada foornada ee isku dhafan alumina corundum walax dhexdhexaad ah oo foornada kicinta ah
Nidaamyada kala duwan ee habka isticmaalka foornada sidoo kale waxay aad muhiim ugu yihiin nolosha adeegga foornada, iyo hawlo kala duwan oo aan habboonayn ayaa yareyn kara nolosha adeegga foornada. Sidaa darteed, qodobbada soo socda waa in fiiro gaar ah loo yeesho inta la isticmaalayo.
(1) Maaddaama lakabka sinteed ee walxaha ramming ee foornada cusub ay khafiif tahay, habka isticmaalka foornada cusub waa mid aad muhiim u ah. Foornada ugu horreysa ee foornada cusub waa inay ku dartaa 50% biyaha si loo dhalaalayo. Tani waxay ka fogaan kartaa cilladaha sida dildilaaca iyo dildilaaca ay keento qaboojinta degdega ah ee daboolka foornada ka dib marka dhammaan biyaha la sii daayo; foornada cusub waa in si joogto ah loo dhalaaliyaa intii suurtagal ah si looga fogaado dhalaalid joogto ah. Dildilaaca ka dhashay guud ahaan waa in si joogto ah loo dhalaaliyo ilaa 1 toddobaad.
(2) Isku day inaad ka fogaato dhalaalidda heerkul sare inta lagu jiro habka dhalaalidda. Heerkulka sare, dahaarka foornada ayaa ka falcelin doona birta dhalaalaysa ee ku jirta weelka, sida lagu muujiyey qaacidada soo socota: SiO2+2C→Si+2CO. Heerkulka sare ee sare, C iyo hoose ee Si, daxalka foornada foornada ayaa kordhin doona, gaar ahaan in Way caddahay marka foornada cusubi tahay, markaa isku day inaad iska ilaaliso heerkulka sare adoo hubinaya heerkulka biyaha marka dhalaalayo.
(3) Iska ilaali kulaylka dahaarka foornada. Sababtoo ah heerka kulaylka ee foornada soo noqnoqda ee dhexdhexaadka ah waa mid aad u dhakhso badan, marka dhalaaliyuhu aanu fiiro gaar ah lahayn, kharashka ayaa soo muuqan doona “isku-xidhka” iyo daboolka foornada ayaa u muuqan doona heerkul sare oo heerkul ah ama xitaa ka badanaya refractoriness ee foornada foornada, taas oo keeni karta dahaarka foornada si ay u dhalaaliso oo u daxaliso burburka.
(4) Inta lagu jiro isticmaalka, marka foornada loo baahan yahay in la xiro wakhti dheer sababtoo ah guul darrooyinka iyo sababo kale, birta dhalaalaysa ee foornada waa in la faaruqiyaa si looga fogaado in dahaarka foornada ay waxyeello u geystaan dillaaca foornada foornada. marka birta dhalaalaysa la isku ururiyo.
(5) Isku day inaad isticmaasho lacag nadiif ah marka la isticmaalayo, gaar ahaan marka foornada cusub tahay.
(6) Marka foornada la joojiyo qaboojinta, si looga fogaado qaboojinta degdega ah ee foornada foornada, foornada madhan waa in la qaboojiyo. Isla mar ahaantaana, si looga fogaado dildilaaca ay keento farqiga heerkulka xad-dhaafka ah ee u dhexeeya heerkulka sare iyo hoose ee foornada foornada inta lagu jiro habka qaboojinta, daboolka foornada waa in la daboolaa si loo sameeyo foornada foornada Inta lagu jiro qaboojinta, dhinacyada sare iyo hoose waa xitaa xitaa. , si loo hubiyo nolosha adeegga foornada.
(7) Mar haddii dildilaacyada tooska ahi ay soo baxaan marka ay foornada qabowdahay, marka la bilaabo foornada qabow, waa in foornada lagu dubaa heerkul yar ka hor inta aan la dhalaalin, si marka hore dildilaacyada loo xiro, lagana ilaaliyo dildilaaca inay soo galaan. dildilaaca marka birta dhalaalaysa ay dhalaalto oo dildilaacyadu sii balaadhiyaan.
(8) U fiirso xaaladda foornada inta lagu jiro isticmaalka foornada. U fiirsashada xaaladda foornada waa nooc ka mid ah ilaalinta foornada. Qeybta hoose ee foornada ayaa la cabbiraa 3dii maalmoodba mar, derbiga foornada waa in lagu ilaaliyaa foornada kasta maalin kasta, taas oo hubinaysa badbaadada daboolka foornada. .
(9) Dayactirka iyo dayactirka qalabka foornada induction, sida nadiifinta soo noqnoqda ee gariiradda, nadiifinta burburka gariiradda si looga hortago burburka gariiradda, si looga fogaado burburka foornada ee ay sababtay cilladda qalabku, iyo si wax ku ool ah u wanaajinta nolosha adeegga qulqulka.
