Izixhobo ezihlaziyiweyo zokuphinda zisebenze kwiziko elisebenzayo le-ferrosilicon

Iziko le-Ferrosilicon ikakhulu livelisa i-ferrosilicon, i-ferromanganese, i-ferrochromium, i-ferrotungsten, kunye ne-silicon-manganese alloys. Indlela yokuvelisa isondlo esiqhubekayo kunye nokubetha ngokukhawuleza kwe-iron slag. Yisithando somlilo sombane esisebenza ngokuqhubekayo.

Isithando somlilo se-Ferrosilicon luhlobo lwesithando somlilo esiphezulu, esinokunciphisa ukusetyenziswa kwamandla kunye nokwandisa umkhiqizo, ukwenzela ukuba ubomi besithando somlilo busetyenziswe ixesha elide. Kungale ndlela kuphela apho iindleko zemveliso yeshishini kunye nentsalela yenkunkuma ekhutshwayo engcolisayo inokucuthwa. Oku kulandelayo kwazisa ubushushu bokusabela okwahlukileyo kwiziko le-ferrosilicon. Ukusetyenziswa kwezinto eziphikisayo zezinto ezahlukeneyo kubhekiselele kuphela.

Indawo entsha yokufudumeza impahla: Umgangatho ophezulu umalunga ne-500mm, kunye nobushushu be-500 ℃-1000 ℃, i-airflow ephezulu, ukushisa kwe-electrode conduction, ukutsha kwentlawulo yomhlaba, kunye nokusabalalisa intlawulo ubushushu bokumelana nobushushu. Ubushushu bale nxalenye buhluke, kwaye bufakwe ngezitena zodongwe.

Indawo yokufudumeza: Emva kokuba amanzi aphuphuma ngumphunga, intlawulo iya kuhamba ngokuthe ngcembe ukuya ezantsi kwaye yenzeke utshintsho lwangaphambili kwifom yekristale ye-silica kwindawo yokufudumeza, yandise umthamo, kwaye emva koko iqhekeke okanye igqabhuke. Iqondo lobushushu kweli candelo limalunga ne-1300°C. Yakhiwe ngezitena eziphezulu ze-alumina.

Indawo yeSintering: Liqokobhe eliqhekezayo. Ubushushu buphakathi kwe-1500 ℃ kunye ne-1700 ℃. Isilicon yolwelo kunye nentsimbi ziyenziwa kwaye zithontsizelwe kwidama elinyibilikisiweyo. I-sintering kunye ne-gas permeability yezinto zesithando somlilo zihluphekile. Iibhloko kufuneka ziphulwe ukubuyisela umoya wegesi kunye nokwandisa ukuchasana. Ubushushu kule ndawo buphezulu. Idleka kakhulu. Yakhiwe nge-semi-graphitic carbon - izitena ze-silicon ze-carbonized.

Indawo yokuNciphisa: Inani elikhulu lemimandla enzulu yokusabela kweekhemikhali. Iqondo lobushushu lezowuni yecrucible liphakathi kwe1750°C kunye ne2000°C. Inxalenye engezantsi idityaniswe kumgodi we-arc kwaye isetyenziselwa ukubola kwe-SIC, ukuveliswa kwe-ferrosilicon, ukusabela kolwelo lwe-Si2O kunye ne-C kunye ne-Si, njl. .

Ummandla we-Arc: Kwindawo yomngxuma emazantsi e-electrode, ubushushu bungaphezu kwama-2000°C. Iqondo lokushisa kule ndawo yindawo ephezulu yokushisa kwisithando somlilo kunye nomthombo wokusabalalisa okukhulu kweqondo lokushisa kuwo wonke umzimba wesithando somlilo. Ngoko ke, xa i-electrode ifakwe ngokungekho nzulu, indawo yokushisa ephezulu ihambela phezulu, kwaye iqondo lokushisa eliphantsi kwesithando somlilo I-slag etyhidiweyo ephantsi ayikhuphi kancinci, yenze i-furnace ephantsi, ibangela ukuba umngxuma wempompo uhambe phezulu. I-bottom ethile yesithando sobuxoki ineenzuzo ezithile zokukhusela isithando somlilo. Ngokuqhelekileyo, ubunzulu bokufakwa kwe-electrode bunento eninzi yokwenza nobubanzi be-electrode. Ubunzulu bokufaka ngokubanzi kufuneka bugcinwe kwi-400mm-500mm ukusuka ezantsi kwesithando somlilo. Le ndawo inobushushu obuphezulu kwaye yakhiwe ngezitena zamalahle ezigcadiweyo zesemi-graphite.

Uluhlu olusisigxina lwenziwe ngekhonkrithi ye-phosphate okanye izitena zodongwe. Umnyango wesithando somlilo unokuphoswa ngeentsimbi ze-corundum okanye ubekwe ngaphambili ngezitena ze-silicon carbide.

Ngamafutshane, ngokuhambelana nobukhulu, ubushushu, kunye neqondo le-corrosion yesithando somlilo se-ferrosilicon, ezifanelekileyo, ezihambelana nokusingqongileyo, kunye nezixhobo ezahlukeneyo zezitena eziphikisayo kunye ne-castables kufuneka zikhethwe kwi-lining.
