Sintering ingxaki ye ramming impahla kwisithando somlilo esiphakathi

Umgangatho we-ramming material ye-intermediate frequency furnace inefuthe elithe ngqo ekusebenzeni kakuhle kokunyibilikisa. Udonga olululo olulungileyo lunokunyibilikiswa ngamaxesha angama-600. Eyona nto imbi kakhulu kubushushu obungaphezulu kwe-100, kwaye nobushushu obuninzi kufuneka buphinde bufakwe amaqhina. Ukuqhina rhoqo eludongeni lwesithando somlilo akuchaphazeli nje kuphela ukusebenza kakuhle kwemveliso, kodwa kukwamoshe imali ngokuqhina intlawulo. Oku kulandelayo yindlela echanekileyo yokudibanisa ukusuka kumenzi wezinto zokubopha ezomileyo. …

1. Indima yenzwa yobushushu

Kumsebenzi we-sintering, ukulawulwa kweqondo lokushisa ngokubanzi kubaluleke kakhulu. Ukuze siqonde ngokucacileyo iqondo lokushisa kwisithando somlilo, siya kudibanisa i-2-3 indawo yokulinganisa ubushushu ngezantsi kunye nombindi kwangaphambili, kwaye siqhube inkqubo yethu yokutshisa ngokuhambelana nokushisa okufunyenweyo.

2. Ukongezwa kwebhetshi yokuqala yentlawulo ye-lining yodonga lwesithando somlilo we-sintering

Kwibhetshi yokuqala yentlawulo phambi kwenkqubo yokuntywila, kufuneka sibeke phambili ukwakheka kweekhemikhali zezinto zayo, kuba eyona nto iphambili yodonga lwesithando somlilo sesanti ye-quartz yisilicon oxide, kwaye ukusuka kuhlalutyo lwe-thermodynamics, iC kunye ne-Si ziyi-A. ibhalansi ratio iyafuneka kwiqondo lobushushu elithile. Xa ubushushu bentsimbi etyhidiweyo buphezulu kwaye umxholo we-C uphezulu, umxholo weSi wentsimbi etyhidiweyo kufuneka ube mkhulu, kuba sifuna i-1580-1600 degrees ngexesha lenkqubo ye-sintering yodonga lwesithando somlilo Ngexesha lokubamba ixesha, ukuba intsimbi etyhidiweyo iqulethe umxholo ophezulu we-C kwaye umxholo we-Si awufikeleli kumlinganiselo ofunekayo webhalansi, intsimbi etyhidiweyo iya kukhawulezisa ukutsalwa kwe-silicon ukusuka eludongeni lwesithando somlilo ukuze ulungelelanise lo mlinganiso, okubangela umgca wodonga lwesithando somlilo Ukhukuliseko lwangaphambi kwexesha kunye nokunciphisa kuchaphazela ubomi bayo benkonzo. Kwakhona, ukuba imixholo ye-C kunye ne-Si kwi-batch yethu yokuqala ye-ramming materials iphantsi, ukushisa okuphezulu kuya kubangela ukwanda kwe-iron oxide kunye ne-manganese oxide, kwaye ezi oxides ziya kusebenzisana nodonga lwethu lwesithando somlilo. I-silicon dioxide kumphezulu iphendula ukwenza i-iron silicate kunye ne-manganese silicate, kwaye iindawo zokunyibilika kwezi zinto zimbini zingaphantsi kwe-1350 ℃, kwaye yenza udonga lwethu lwesithando somlilo lube mncinci ngaphambi kwexesha kwaye lunciphise ubomi benkonzo. …

Uthathela ingqalelo ezi ngongoma zimbini zingasentla, enye kukuqwalasela ukuxinana kwezinto zeramming ezongeziweyo. Yonke inkqubo yokunyibilika kweziko lethu lombane kukuba amandla ombane aguqulwa abe amandla ombane ngokusebenzisa ikhoyili, kwaye ke intsimi kazibuthe isabela kunye nentlawulo yesinyithi ukuguqula amandla ombane, kwaye ke ukusuka kumandla ombane ukuya kumandla ombane. Ukuguqulwa kwamandla okushisa, ngenxa yokuba i-crucible yi-crucible mold crucible xa i-oven i-oven, ukuba indawo yokutya ngaphakathi kwesithando somlilo ikhululekile, inxalenye ye-crucible iya kusabela ngokugqithiseleyo kwintsimi yamagnetic, ebangela ukuba ukufudumala kukhawuleze kakhulu, kubangela i-deformation kunye ne-bulging ngaphakathi (inxalenye iphinda ichaphazeleke ngobunzima be-crucible mold. Ngeli xesha, i-quartz yesanti yodonga lwesithando somlilo ayikabikho i-sintered kwaye iqiniswe, kwaye i-refractory material iya kuzalisa indawo ephosakeleyo ye isikhunta, okubangela ukuncipha kobuninzi bezinto ezifakwe eludongeni lwesithando somlilo kunye nokuchaphazela ubomi bayo benkonzo.
