Mefuta ea ho chesoa ha sebōpi thepa ea lera?

Lintho tse entsoeng ka sebōpi sa induction li boetse li bitsoa induction furnace refractory material, induction furnace dry vibrating material, induction furnace knotting material, induction furnace ramming material, e arotsoe ka lisebelisoa tsa acidic, neutral le alkaline. Lisebelisoa tse nang le acidic li entsoe ka quartz e hloekileng haholo, Quartz e qhibilihisitsoeng ke thepa e ka sehloohong e tala, li-additives tse kopantsoeng li sebelisoa e le moemeli oa sintering; thepa ea sebōpi e sa nke lehlakore e entsoe ka alumina le lisebelisoa tse phahameng tsa aluminium e le thepa e ka sehloohong e tala, ‘me motsoako o kopanyang o sebelisoa e le moemeli oa sintering; thepa ea motheo ea lesela la sebōpi e entsoe ka corundum e hloekileng e phahameng le motlakase o hloekileng oa Fused magnesia le spinel e phahameng ea bohloeki e sebelisoa e le lisebelisoa tse ka sehloohong tse tala, ‘me li-additives tse kopantsoeng li sebelisoa e le lisebelisoa tsa sintering.

Ho na le mefuta e meraro ea lisebelisoa tsa sebōpi sa induction. E ‘ngoe ke lesela la acidic, le entsoeng ka ramming e omeletseng ea lehlabathe la quartz,’ me moemeli oa tlamahano ke borax kapa boric acid; e ‘ngoe ke ramming e omeletseng le ho bopa ha magnesia,’ me moemeli oa ho kopanya hape ke borax kapa boric acid. E ‘ngoe ke lesela la sebōpi le sa nke lehlakore, le entsoeng ka rammed le ho thehoa ho tloha klinka e phahameng ea alumina bauxite. Lilemong tsa morao tjena, ka tsoelo-pele ea thekenoloji le ho hlaha ha lisebelisoa tse ncha tse sa tšoaneng, lisebelisoa tse ngata tse ncha tsa lesela li boetse li hlahile ka thepa ea lesela la sebōpi sa induction.

1. Lera la asiti

Lesela la sebōpi sa acidic haholo-holo ke lehlabathe la quartz, le theko e tlaase, le ajoa ka bongata, ho kenya letsoho hantle, litlhoko tse tlaase tsa kaho, liphoso tse fokolang nakong ea tšebeliso, le tlhahiso e batlang e tsitsitse. Leha ho le joalo, lehlabathe la quartz le na le refractoriness e tlase mme ha le khone ho fihlela litlhoko tsa libopi tse kholo tsa induction. ‘Me ho na le phetoho ea karolo ea bobeli nakong ea ho futhumatsa, botsitso bo tloaelehileng bo futsanehile, botsitso ba lik’hemik’hale ha bo tšoanelehe,’ me bo mpa bo sebetsana le slag ho etsa kutu. E le ho thibela liphoso tsena, ho ka sebelisoa quartz e kopantsoeng. Likahare tsa eona li phahame, litaba tsa silicon dioxide li kholo ho feta 99%, refractoriness e tsoela pele haholo, haufi le ntlha ea ho qhibiliha, ‘me ha ho na phetoho ea karolo ea bobeli ha ho futhumatsa, ha ho na phetoho ea maemo a futhumatsang,’ me ho sisinyeha ha mocheso ho tsitsitse. . Thobalano le eona e tsoetse pele haholo.

2. Lera le sa nke lehlakore

Corundum e kopantsoeng e sebelisoa e le lesela la sebōpi sa induction. Hobane ntlha e qhibilihang ea corundum e tšoeu e phahametse 2050 ℃, ho thatafala ho feta 8. Ha e khone ho apara, e hanyetsa mocheso o phahameng, ‘me e na le botsitso ba lik’hemik’hale ho feta quartz. E loketse mocheso o phahameng oa tšepe ea tšepe kapa lesela le leholo la sebōpi. Tšobotsi ke hore e boetse e na le mefokolo ea phetoho ea mekhahlelo le coefficient e kholo ea ho atolosa mocheso. Ha e le hantle, ho kenya letsoho ha spinel powder ho ka ntšetsa pele ho hanyetsa ha kutu le botsitso bo tloaelehileng.

3. Lesela la alkaline

Lesela la sebōpi la alkaline la setso le thehoa ka ho omella hoa magnesia. Monyetla ke refractoriness e phahameng, e haufi le 2800 ℃, sekoli ke hore coefficient ea katoloso e kholo, e bonolo ho phunyeha, lesela la magnesia ha le na kutu, le phela nako e telele, theko e tlaase, ‘me le sebelisoa haholo. Ho kenya letsoho ho phofo e tšoeu ea corundum kapa phofo ea spinel e ntlafatsa haholo bophelo ba tšebeletso.

4. Lera la mokokotlo

Lesela la mokokotlo ke mofuta o mocha oa thepa ea lesela. E bōptjoa ho tloha alumina le magnesia, e chesoa ka mocheso o phahameng kapa e fetisetsoa pele ho spinel ka fusion ea motlakase, ebe e hlahisa litekanyetso tse sa tšoaneng tsa likaroloana kamoo ho hlokahalang. E sebelisoa e le lesela la sebōpi sa induction, ‘me moemeli oa tlamahano o ntse a khetha Ho khetha borax kapa boric acid e na le melemo ea lesela la sebōpi sa white corundum le magnesia sebōpi sa magnesia, ha se ntse se thibela mefokolo ea sona. Ke tataiso ea nts’etsopele ea lesela la sebopi se seholo sa induction le lesela la sebōpi sa mocheso o phahameng. Lisebelisoa tse ngata tsa sebōpi tse tsoang linaheng tse ling ke tsa mofuta ona.

5. Theknoloji e ncha le lisebelisoa tse ncha tsa lisebelisoa tsa lesela la sebōpi

① Kenya letsoho ho phofo e hloekileng haholo (haholo-holo ka li-micron tse ‘maloa) lisebelisoa tsa masela a sebōpi a setso, tse ka ntlafatsang ho hanyetsa ha kutu le botsitso ba mocheso oa thepa ea sebōpi, joalo ka silika ea silika, phofo e nyenyane ea alumina, phofo e tšoeu ea corundum, spinel micro powder, joalo-joalo.

② Ho bopa ho omme. Lisebelisoa tsa setso tsa sebōpi kaofela li entsoe ka phofo e omileng le ramming e omileng. Bothata ke hore ho bonolo ho chromatograph le ho etsa bofokoli joalo ka lefeela. Ka mokhoa oa semi-dry, 2% ho 3% ho kopanya metsi ho sebelisoa ho fokotsa chromatography, ‘me botšepehi bo botle,’ me bo ke ke ba baka kotsi e ngata haholo. E hloka nako e teletsana feela ka ontong ea mocheso o tlase.

③ Ts’ebetso ea ho bopa e omeletseng e kenya letsoho ho samente e hloekileng ea calcium aluminate, e nang le lesela la sebōpi le hloekileng la asiti kapa le sa nke lehlakore; ha e ntse e le seboping sa alkaline, e kenya letsoho ho magnesium oxide, sodium hexametaphosphate, joalo-joalo.
