Zithini iindidi ze ityhini izixhobo zelinen?

Isixhobo sokufakelwa kwesithando somlilo sikwabizwa ngokuba yi-induction furnace refractory material, i-furnace induction dry vibrating material, i-induction furnace knotting material, imathiriyeli yokufakwa kwesithando somlilo, yahlulwe yaba yi-acidic, neutral, kunye ne-alkaline. Izinto ze-acidic ze-lining zenziwe nge-quartz ecocekileyo, i-quartz etyhidiweyo iyona nto iphambili, izongezo ezidibeneyo zisetyenziswa njenge-agent agent; isithando somlilo esingathathi hlangothi senziwe nge-alumina kunye nezinto eziphezulu ze-aluminium njengeyona nto iphambili, kwaye i-additive composite isetyenziswe njenge-agent agent; izinto ezisisiseko zelinen yesithando somlilo zenziwe nge-high-purity fused corundum kunye ne-high-purity electric Fused magnesia kunye ne-high-purity spinel zisetyenziswa njengezona zinto ziphambili, kwaye izongezo ezidibeneyo zisetyenziswa njenge-agent ye-sintering.

Kukho iintlobo ezintathu zemathiriyeli yokufakwa kwesithando somlilo. Enye i-acidic lining, eyenziwa yi-ramming eyomileyo yesanti ye-quartz, kunye ne-agent edibeneyo i-borax okanye i-boric acid; enye yi-ramming eyomileyo kunye nokubumba i-magnesia, kwaye i-agent edibeneyo nayo i-borax okanye i-boric acid. Enye yilayini yesithando somlilo engathathi hlangothi, enqanyulwe kwaye yenziwe kwi-clinker ephezulu ye-alumina bauxite. Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji kunye nokuvela kwezixhobo ezintsha ezahlukeneyo, izinto ezininzi ezitsha zombane ziye zavela nakwizinto zokufakelwa kwesithando somlilo.

1. I-Acid lining

I-Acidic furnace lining ikakhulu yisanti yequartz, enexabiso eliphantsi, elisasazwe ngokubanzi, ukugquma okulungileyo, iimfuno eziphantsi zokwakha, iziphene ezimbalwa ngexesha lokusetyenziswa, kunye nemveliso ezinzileyo. Nangona kunjalo, isanti ye-quartz ine-refractoriness ephantsi kwaye ayikwazi ukuhlangabezana neemfuno ze-furnaces induction induction enkulu. Kwaye kukho utshintsho lwesigaba sesibini ngexesha lenkqubo yokufudumala, ukuzinza okusemgangathweni kubi, ukuzinza kweekhemikhali akufanelekile, kwaye kusabela nje nge-slag ukwenza i-corrosion. Ukuthintela ezi ziphene, i-quartz edibeneyo ingasetyenziswa. Umxholo wayo uphezulu, umxholo we-silicon dioxide mkhulu kune-99%, i-refractoriness iqhubela phambili ngokuphawulekayo, kufuphi nendawo yokunyibilika, kwaye akukho tshintsho lwesigaba sesibini xa kushushu, akukho tshintsho lomgangatho wokufudumeza, kunye nokutshatyalaliswa kwe-thermal kuzinzile. . Ukwabelana ngesondo nako kuhambele phambili kakhulu.

2. Umgca ongathathi hlangothi

I-corundum edibeneyo isetyenziswe njengentambo yesithando somlilo. Ngenxa yokuba indawo yokunyibilika ye-corundum emhlophe iphezulu njenge-2050 ℃, ukuqina kuphezulu njenge-8. Ayigugi, i-high-temperature resistant, kwaye inozinzo olungcono lweekhemikhali kune-quartz. Ifanelekile kwintsimbi ephezulu yokushisa okanye i-furnace lining enkulu. Uphawu kukuba nayo ineziphene zokutshintsha kwesigaba kunye ne-coefficient enkulu yokwandisa i-thermal. Enyanisweni, ukuthatha inxaxheba kwe-spinel powder kunokuqhubela phambili kakhulu ukuchasana kwe-corrosion kunye nokuzinza okusemgangathweni.

3. Umgca wealkaline

Iziko le-alkaline yesithando somlilo senziwa yi-ramming eyomileyo ye-magnesia. I-advanteji yi-refractoriness ephezulu, kufuphi ne-2800 ℃, isiphene kukuba i-coefficient yokwandisa inkulu, kulula ukukrazula, i-magnesia lining i-corrosion resistant, ubomi obude, ixabiso eliphantsi, kwaye lisetyenziswa ngokubanzi. Ukuthatha inxaxheba kwi powder emhlophe ye-corundum okanye i-spinel powder iqhubela phambili kakhulu ubomi benkonzo.

4. Umgca womqolo

I-Spinel lining luhlobo olutsha lwezinto zokugqoka. Ibunjwe ukusuka kwi-alumina kunye ne-magnesia, igxothwe kwiqondo lokushisa eliphezulu okanye ifakwe ngaphambili kwi-spinel ngokuxutywa kombane, kwaye emva koko ivelise imigangatho yamasuntswana ahlukeneyo njengoko kufuneka. Isetyenziswe njenge-furnace induction lining, kwaye i-agent edibeneyo isekho Ukukhetha i-borax okanye i-boric acid ineenzuzo ze-white corundum i-furnace lining kunye ne-magnesia furnace lining, ngelixa ikhusela iziphene zayo. Isalathiso sophuhliso lwe-firnace induction enkulu kunye ne-high-temperature ye-furnace. Izinto ezininzi ezifakwe kwi-furnace lining zikolu hlobo.

5. Itekhnoloji entsha kunye nezixhobo ezintsha zezixhobo zokubeka isithando somlilo

① Thatha inxaxheba kwi-ultra-fine powder (ubukhulu becala kwii-microns ezimbalwa) kwizixhobo zelinen zesithando somlilo, ezinokuthi ziphucule ukuxhathisa ukubola kunye nozinzo lobushushu bobushushu bezinto zombane zomlilo, njenge-silica umgubo omncinci, i-alumina encinci, i-white corundum ipowder encinci, spinel micro powder, njl.

②Ukubumba okomileyo. Iziko lemveli zomlilo zonke zenziwe ngumgubo owomileyo kunye ne-ramming eyomileyo. Isiphene kukuba kulula ukwenza ichromatograph kwaye wenze iziphene ezinje ngokungenanto. Kwindlela eyomileyo, i-2% ukuya kwi-3% yokuxuba amanzi isetyenziselwa ukunciphisa i-chromatography, kwaye ingqibelelo ilungile, kwaye ayiyi kubangela ingozi enkulu. Ifuna kuphela ixesha elide kwi-oven yobushushu obuphantsi.

③Inkqubo yokubumba eyomileyo ithatha inxaxheba kwisamente esulungekileyo ye-calcium aluminum, ene-acidic ecocekileyo okanye engathathi hlangothi yesithando somlilo; ngelixa i-alkaline i-furnace lining, ithatha inxaxheba kwi-magnesium oxide, i-sodium hexametaphosphate, njl.
