Na seo Refractory tšepe?

Ha a bua ka tšepe refractory, ho e utloisisa hore na tšepe oela tlas'a tlhaloso ena. Vanadium, tungsten, molybdenum, niobium, rhenium, tantalum, zirconium le hafnium - tšepe eo qhibiliha mocheso fihla 1650-1700 ° C.

Foromo e hloekileng, tšepe refractory u se ke ke sa etsahala linthong tsa tlhaho. Di fumaneha concentrates manya sebelisa rarahaneng tse tharo-sethaleng theknoloji. Bohato ba pele e na le ka ho bula mamelisisa, ka hona ha ho ke ho itšehla thajana le ho itlhoekisa tsa metsoako lik'hemik'hale 'me qetellong - hlaphoheloa le ho hloekisoa ha tšepe.

Pharalla tsa tšebeliso ea tšepe refractory bophara ka ho lekana. tšepe Refractory sebelisoa ka boenjiniere le ho phetha molao feela, shipbuilding, elektronike le lik'hemik'hale liindasteri, ka lebaka la thepa ea bona buka e ikhethang, e leng ho sebelisa ha bona e le thepa e mocheso kenelwe lits'epe tse kopantsoeng.

Nahana ka e mong le e tsa tšepe refractory ka thoko.

Vanadium - tiileng tšepe tšepe-ea bohlooho ka 'mala. Lebitso la tšepe ena e ne e le ho tlotla molimotsana oa botle Vanadis, ka lebaka la 'mala oa letsoai tse kenyelelitsoe sebopeho lona. Vanadium e manganga ho metsi le acid tse sa tšoaneng. E sebelisitsoeng ka eona ka tlhahisong ea rabara, ceramic, khalase, 'me ho hlakile steels. Ka eleketrode ntle le libeteri e sebediswa vanadium pentoxide.

Tungsten - bohlooho tiileng tšepe, ho sebelisa maemo a tekanyetso e ka bitsoa tšepe fetisisa refractory, sebelisoa ka metallurgy e le motheo e. Lebitso la wolframite matsoai tungsten ile ka amohela ho (ka Lane ka. Ka eona. "Wolf bubble"), ea neng a tsebahala ka ho lekholo la bo15 la lilemo e le tungsten sitisoa thini qhibilihisa. Wolfram fumana kopo ea eona e leng tlhahisong ea likepe e khethehileng sebediswa bakeng sa ho hōla kristale le 'ngoe, qhibiliha khalase, jj ..

Molybdenum - refractory tšepe silevera,-tšoeu mmala. Molybdenum hang bonolo hore ho kena moea le itšoara joang le hydrogen etsahala ha molybdenum fihla ntlha qhibiliha (2620 ° C). tšebeliso ea eona e leng tlhahiso ea linaleli bakeng sa mabone motlakase, hammoho le bakeng sa tlhahisong ea cathodes lisebelisoa tsa elektronike.

Niobium - khanya ea bohlooho refractory tšepe, habonolo phekoleha, manganga ho ts'enyeho. Ke karolo ea tšepe glassware, mocheso manganga le ts'enyeho manganga lits'epe tse kopantsoeng, ho ntlafatsa thepa tsa bona ho phetha molao feela.

Rhenium ke har'a matla ka ho fetisisa tsa refractory tšepe. Lits'epe tse kopantsoeng tsa leseli bohlooho tšepe sena ka tungsten le molybdenum mollo ho hanyetsa le ho sebelisoa bakeng sa tlhahiso ea lifofane supersonic le metsu.

Tantalum - lik'hemik'hale tsitsitseng refractory tšepe khanya ea bohlooho le 'mala o pherese. metallurgy e sebelisoa e le karolo ea lits'epe tse kopantsoeng ts'enyeho manganga, mocheso manganga le thata.

E hloekileng zirconium e benyang tšepe eo e bonolo ho sebetsa ka bobedi a chesang le a batang sebetsa. The tšobotsi khethollang ea tšepe ka hore e na le ho hanyetsa phahameng haholo ho ts'enyeho.

Hafnium fumanoa zirconium tšepe. Metal le glitter silevera, e sebelisoa ho hlahisa cores monya ea reactors nyutlelie.
