Innovative refractory zvinhu zveanoshanda ferrosilicon furnaces
Ferrosilicon furnaces inonyanya kugadzira ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, uye silicon-manganese alloys. Iyo nzira yekugadzira ndeyekuenderera mberi kwekudya uye kupindirana kurova kwesimbi slag. Icho chivira chemagetsi cheindasitiri chinoshanda nguva dzose.
Ferrosilicon furnace imhando yemoto-inopedza simba, iyo inogona kuderedza kushandiswa kwesimba uye kuwedzera kubuda, kuitira kuti hupenyu hwevira hugone kushandiswa kwenguva yakareba. Nenzira iyi chete ndipo panogona kudzikiswa mutengo wekugadzirwa kwebhizinesi uye marara anoburitsa tsvina. Izvi zvinotevera zvinounza maitiro akasiyana ekushisa kweferrosilicon furnaces. Iko kushandiswa kwezvinhu zvinoramba zvezvinhu zvakasiyana ndezvekutarisa chete.
New material preheating area: Iyo yepamusoro-soro inosvika 500mm, ine tembiricha ye500 ℃-1000 ℃, yakakwirira-tembiricha yemhepo, electrode conduction kupisa, kupisa kwechaji yepasi, uye kuchaja kugovera ikozvino kupokana kupisa. Kupisa kwechikamu ichi kwakasiyana, uye kunoputirwa nezvidhinha zvevhu.
Preheating zone: Mushure mekunge mvura yanyungudika, iyo charge inozofamba zvishoma nezvishoma ichidzika uye ichiita shanduko yekutanga musilica crystal fomu munzvimbo yekupisa, kuwedzera muhukuru, uye yobva yatsemuka kana kuputika. Tembiricha iri muchikamu ichi inosvika 1300°C. Yakavakwa nezvidhinha zvakakwirira zvealuminium.
Sintering nzvimbo: Ndiyo crucible shell. Tembiricha iri pakati pe1500℃ ne1700℃. Liquid silicon nesimbi zvinogadzirwa uye zvinodonhedzwa mudziva rakanyungudutswa. Iyo sintering uye gasi permeability yechoto zvinhu hazvina kunaka. Mabhuroki anofanira kuputswa kuti adzorere kufefetedza kwegasi uye kuwedzera kuramba. Kupisa munzvimbo iyi kwakakwira. Very corrosive. Inovakwa ne semi-graphitic kabhoni - carbonized silicon zvidhinha.
Deduction zone: Nhamba huru yezvakanyanya zvinhu zvemakemikari reaction zones. Tembiricha yenzvimbo yecrucible iri pakati pe1750 ° C uye 2000 ° C. Chikamu chezasi chakabatana nearc cavity uye inonyanya kushandiswa pakuparara kweSIC, chizvarwa cheferrosilicon, maitiro emvura Si2O neC uye Si, etc. Nzvimbo dzepamusoro-tembiricha dzinofanirwa kugadzirwa nesemi-graphite yakagochwa kabhoni zvidhinha. .
Arc zone: Munzvimbo yegomba pazasi pe electrode, tembiricha iri pamusoro pe2000°C. Tembiricha iri munzvimbo iyi ndiyo yakanyanya kupisa nzvimbo muchoto chese uye kunobva kupararira kwekushisa kwakanyanya mumuviri wese wechoto. Naizvozvo, kana electrode ikaiswa zvisina kudzika, tembiricha yakakwira inokwira kumusoro, uye tembiricha yepasi yechoto Yakadzika yakanyungudutswa slag haina kuburitswa, ichigadzira nyuchi yenhema pasi, zvichiita kuti gomba repombi riende kumusoro. Imwe yenhema yevira rezasi ine zvimwe zvinobatsira zvekudzivirira kwechoto. Kazhinji kutaura, kudzika kwekuiswa kwe electrode kune zvakawanda zvekuita nedhayamita ye electrode. Kudzika kwakawanda kunofanirwa kuchengetwa pa400mm-500mm kubva pasi pechoto. Chikamu ichi chine tembiricha yepamusoro uye inovakwa nesemi-graphite yakagochwa zvidhinha zvemarasha.
Chimiro chekusingaperi chinogadzirwa nephosphate concrete kana zvidhinha zvevhu. Gonhi rechoto rinogona kukandwa necorundum castables kana pre-yakaiswa nesilicon carbide zvidhinha.
Muchidimbu, maererano nehukuru, tembiricha, uye dhigirii rekuora kwechoto cheferrosilicon, chakakodzera, chakanakira zvakatipoteredza, uye zvinhu zvakasiyana-siyana zvezvidhinha zvinoramba uye zvinokandwa zvinofanira kusarudzwa pakugadzira.
