Temperature Kukalwa Futhi Control Of Precision Ekubunjweni

Abakhiqizi bokuphonsa ngokunemba abaphumelelayo bayazi ukubaluleka kwenqubo yokulawulwa kokukhiqizwa kwekhwalithi ephezulu. Ukuhlukahluka okuyinhloko kunqubo yokusakaza kufaka phakathi izinga lokushisa lesikhunta, izakhiwo zokufudumeza ezishisayo zesikhunta, isikhathi somjikelezo kanye nendlela ye-opharetha, njll. Noma kunjalo, inqubo eguquguqukayo ebaluleke kakhulu ukushisa kwensimbi. Ngo inqubo ngokunemba ekubunjweni, nesilinganiso non-contact lokushisa yensimbi unezinkinga eziningi ezinkulu. Kodwa-ke, iqoqo lamadivayisi athuthukiswe muva nje anganikeza impendulo enembile yesikhathi sangempela, eveza izinkinga ezingaba khona.

Ukubaluleka kokushisa

Enqubeni yokuphosa ngokunemba, ikakhulukazi kunqubo "ye-eksisi elinganayo", izinga lokushisa lensimbi liyinto evelele, ngakho-ke, ibuye ibe nomthelela oqondile kuzimpawu eziningi zekhwalithi. Uma ukulinganisa nokulawula kungafanele, umehluko ekushiseni kwensimbi kuzothinta usayizi wokuphosa ophelile, usayizi wokusanhlamvu, i-porosity (ingaphakathi nengaphakathi), izakhiwo zemishini, ikhwalithi yomkhiqizo (okungukuthi, ukuthambekela kokudabuka okushisayo), ukugcwala kokuncane Izingxenye ezinezindonga, njll. Yenza umthelela.

Ngakho-ke, ukwenza ngcono ukukala nokulawula ukushisa kwensimbi kuzothuthukisa ikhwalithi nokukhiqiza, kunciphise izindleko zokulungisa nezabasebenzi, futhi kunciphise nezindleko zokuhlola nezindleko zesinxephezelo sesikweletu.

Ubunzima besilinganiso sokushisa

Ukusakazwa ngokunemba, ikakhulukazi ukusakazwa ngokunemba kusetshenziswa imishini yokuncibilika kokungeniswa, imvamisa isebenzisa uhlobo oluthile lwe-infrared radiation thermocouple noma i-pyrometer njengendlela yokuqala noma yesibili yokulinganisa kwensimbi. Abantu abasebenzisa ama-pyrometers ajwayelekile kungenzeka bangaqondi imithombo engaba khona yephutha ezilinganisweni zabo, kepha bamane banake izimo "zobuciko" zethuluzi, futhi bavame ukudukiswa. Lokhu kuchazwa ngokunemba kumane nje kuyizinjongo ezinhle endaweni elabhoratri. Ezinye izimo emhlabeni wangempela zingaholela kumanani amaphutha wokulinganisa aphezulu ngokumangazayo. Zifaka (kepha azikhawulelwanga) kokulandelayo:

• Ukuzijabulisa okungaziwa / okushintshayo-izinhlobonhlobo zama-alloys, imiphumela yokuphazamiseka, izinga lokushisa kanye nokuthembela ebangeni, kanye nezinguquko ekwakhiweni ngesikhathi sokucutshungulwa, njll., Konke lokhu kudlala indima ekungalindeleni kokungabikho.
• Ukuphuma kwe-Steam: Ukuncibilika kwengcindezi ephezulu (eduze nangaphezulu kwengcindezi yasemkhathini), igesi echichimayo echibini elincibilikisiwe noma i-crucible izokwandisa noma inciphise imisebe yokushisa, ngaleyo ndlela idale amaphutha.
• Isithiyo somgodi wokuqapha: Okwezinsimbi eziningi, noma ikuphi ukuncipha kwesiginali kuzokwenza ukuthi inani lesibonakaliso sokushisa lehle; ukungcola efasiteleni lokubuka kuthinta ukunemba kwama-pyrometers amaningi.
• Okubukwa kwewindi okwenziwe ngengilazi: akuzona zonke izibuko ezinezinto zokudlulisela ezifanayo; ezinye zinemibala "empunga", kanti izakhiwo zokudluliswa kwezinye izingilazi zishintsha ngobude bemagagasi. Lokhu kuzodala ukuthi i-pyrometer ejwayelekile yehluleke.
• Ukulinganisa: Izinga lomkhakha ukulinganisa kanye ngonyaka. Kodwa-ke, ukukhukhuleka nokwehluleka kwensimbi kunesheduli yayo. Indlela ekahle yokulinganisa zonke izingxenye ze-optical ezisetshenziswe efektri (ingilazi yokubuka noma isibuko sokubuka).
• Ukulinganiswa kwensimbi: ukukhomba ngelensi kudinga izindlela ezimbili ezibonakalayo ukugqagqana ngokunembile, okuzothinta wonke amazinga ama-pyrometers ajwayelekile.

Lobu bunzima buhlukile ekulinganisweni kokushisa kwe-optical. Ngasikhathi sinye, kukhona nobunzima obuhlobene nenqubo, obucindezela isilinganiso sokushisa kwanoma yiluphi uhlobo lwezinsimbi zomculo, kufaka phakathi:

• Ububanzi obamukelekayo bokuhlukahluka kwenqubo: Ngaphandle kokuthi isithando sonke sokuncibilika sisesimeni esizinzile (imvamisa, lokhu akunangqondo), ngaphandle kwalokho, ngesikhathi senqubo yokusakaza, izinga lokushisa lizoba nebanga, futhi kubaluleke kakhulu ukuthi leli banga lokushisa Kufanele libe ikwazi ukuqinisekisa ikhwalithi yomkhiqizo.
• Amandla wokucubungula amasiginali: Yonke i-analog eya ekuguqulweni kwedijithali noma yedijithali ekuguquleni kwe-analog phakathi kwezinsimbi zokulinganisa nemishini yokulawula ingumthombo ongaba nephutha, futhi uhla olubanzi lwe-analog luholela ekushodekeni kokunemba.
• Ubuchwepheshe bokuncibilika: Ubuchwepheshe obuncibilikayo bungadala ukubila kwesikhashana kwezinto ezinomfutho ophakeme, ukuphazamiseka ebusweni bechibi elibunjiwe noma ukwakheka kwemikhiqizo yokuphendula, konke okuzodala amaphutha kuma-pyrometers ajwayelekile.
• Ukuqondanisa phakathi kwama-ingots, ama-crucibles namakhoyili: Ngezimpawu zomjikelezo oncibilikayo, lezi zinto ezintathu zohlelo lokuncibilika zibalulekile. Ukufaniswa okungafanele kuzodala ukuncibilika okuhamba kancane nokungalingani, ukushisa kwasendaweni noma ukuvuvukala. Lezi futhi ziyimithombo yamaphutha kuma-pyrometer ajwayelekile.

Isibonisi sokushisa okuphezulu ukuxazulula inkinga

Ubuchwepheshe besilinganiso sokushisa okuphezulu bunezinzuzo zako zemvelo: akukho ukungcola, akukho ubuthi benzwa lapho bususwa; ukufakwa nokusetshenziswa okulula; ukukala okuqhubekayo kungenziwa; azikho izinto ezisetshenziswayo; ukwehluleka okuyinhlekelele (ukulahleka komsebenzi wokulinganisa) akuvamile neze. Manje, ukuthuthuka kwesayensi ye-pyrometry kusombulule izinkinga ezahlukahlukene ezihambisana nomhlaba wangempela osetshenziswayo. I-pyrospectrometer iyithuluzi elisha sha, iyisistimu yochwepheshe yohlobo lwe-pyrometer yamaza amaningi, inekhono elihle ekuxazululeni lezi zinkinga.

Ngaphezu kokunikeza ukunemba okuhle kakhulu emhlabeni wangempela, i-spectrometer yamandla okushisa aphezulu inezinye izinzuzo eziningi: inganikeza ukufundwa kwesikhathi sangempela kwekhwalithi nokubekezelelana (okungukuthi, izinga lokungaqiniseki ngesikhathi sokulinganisa) phakathi nesilinganiso ngasinye; futhi ingahlinzeka ngamandla wesiginali, Ukuqhathanisa phakathi kwelitshe nenhloso efanelekile ngaphansi kwezinga elifanayo lokushisa nombuso. Le misebenzi emibili ingahlinzeka ngemininingwane ebalulekile mayelana nempahla eluhlaza kanye nenqubo yenqubo, isize ukuqinisekisa ukwakheka okulungile kwe-alloy futhi ikhombise ukuthi ngabe ingxubevange iyabiliswa futhi yahwamuka yini. Ngokusobala, abasebenzisi abanolwazi lolu lwazi futhi bangalusebenzisa kwezinye izinkambu ezisezingeni eliphakeme.

Ezinhlobonhlobo zezicelo ezahlukahlukene, ama-spectrometer wokushisa okuphezulu axazulule ubunzima besilinganiso sokushisa esingathintani.

• I-Emissivity: I-Emissivity izoshintsha ngeqoqo ngalinye lamasampuli wezinto ezibonakalayo, okuwukuhlangana phakathi kwezibalo zethiyori ekulinganisweni kokushisa okuphezulu nokuziphatha kwempahla emhlabeni wangempela. Ukuze umkhakha ngokunemba thusi, the emissivity of izinsimbi kuyehluka kakhulu. Kunoma isiphi isampula, ukuphuma kwayo kuncike ezimweni zomlando wokwakheka, izakhiwo zemishini nezishisayo, ubude bemitha lapho kukalwa khona, kanye namazinga okushisa uqobo. Abahlaziyi bakholelwa ukuthi iphutha lokulinganisa lokushisa lilingana nephutha elihambisanayo le-emissivity, okungukuthi:
• Phakathi kwazo: T izinga lokushisa, ukujabulisa, i-andT ne-Δ amaphutha abo afanele. Ngokuphonsa ngokunemba, inani le-emissivity yensimbi engamanzi livame ukuba sebangeni le-0.15 kuye ku-0.30, futhi inani elincane le-emissivity ku-denominator lizoba nomthelela omkhulu ephutheni lokushisa.

Isitolo esitholwayo singanikela ngezingxenye ezenziwe ngezinto ezingama-20 noma ezingama-30 ezahlukahlukene zokuhlanganisa. I-quantification yomthelela wenani elincane lokuguqulwa kwezinto zensimbi ku-emissivity yezinsimbi ayenzwanga ngezinga elikhulu. Ngakho-ke, ayikho imanuwali yokunikezwa kwama-alloys wokulingisa ngokunemba. . Ukufana kokuqanjwa akukwazi ukusetshenziswa ukulinganisa ubumnandi, inani elincane lezithasiselo lingakushintsha kakhulu ukuvela. Njengoba kukhonjisiwe kuMdwebo 1, ukungafani kwama-alloys amabili aboniswe ku-figure, umehluko ekubunjweni kungu-2% wesisindo se-athomu sento eyengeziwe. Umehluko owumphumela wobumnandi ubangela ukuthi i-pyrometer "ilinganiswe" ngokusho kwengxubevange ukukhiqiza iphutha lokufunda lama-degree angamakhulu amaningana. Amaphutha amakhulu azodala izinxushunxushu zenqubo futhi avale isithando somlilo izinsuku ezimbalwa.

I-pyrospectrometer iyi-pyrometer engadingi ukulungiselela noma yiluphi ulwazi kusengaphambili futhi engenza izilinganiso ezinembile, kungakhathalekile ukuthi kunjani, futhi ayivinjelwe imvelo. Kukhombisa ithempelesha nokuthakazelisa okurekhodwe yi-FAR izinga lokushisa eliphakeme lokuqapha ama-alloys okususa i-nickel-based. Kungabonakala emfanekisweni ukuthi ushintsho ngalunye lwenani lokusetha amandla lubangela ukwanda okufana nokwesipikha emissivity, okubangelwa ukuphazamiseka kokunyakaziswa kwamandla kagesi kwento encibilikisiwe, okuzoqinisa ukungabikho. Ukuhamba ketshezi kwakha umgodi omncane, okwandisa ukumuncwa nokukhishwa ngenxa yomphumela wokucabanga okuningi. Okwesibili, lapho ukuncibilika kuphola, i-emissivity iba noshintsho olufana nesinyathelo: cishe ngo-1: 15, izehlakalo zehliswa ngaphezulu kuka-10%, ukusuka ku-0.245 kuye ku-0.220.

Lo mphumela uhambisana nokubilisa nokuhwamuka kwezinto ze-alloy. Lapho lolu shintsho lwenzeka, izinga lokushisa lihlala lingaguquguquki. Ekugcineni, ukuncibilika kuyabanda futhi izinguquko zomsebenzi zishintsha kakhulu, zisuka ku-0.22 ziye ku-0.60. Izinga lokushisa elincipha kancane kanye nokuhamba kancane kokunyuka kancane ngesikhathi esisodwa kukhombisa ukuthi inqubo yokuqina kwensimbi iba sesimweni sokuxega, kunokuba kube noshintsho olungazelelwe esigabeni njengamanzi siphenduka iqhwa. Umdwebo 3 ukhombisa inqubo efanayo ne-Figure 2, kepha kulokhu kukhishwe i-pyrometer ejwayelekile. Ngaphezu kwephutha elikhulu lokushisa, kufanele kuqashelwe ukuthi ngesikhathi senqubo yokupholisa amandla, ama-pyrometers ajwayelekile awakwazi ukukala. Phakathi kuka-1: 35 no-1: 50, i-pyrometer ibike ukwanda kwezinga lokushisa. Lesi yisimo esingelona iqiniso, esibangelwa ukwanda kokushiswa phakathi nenqubo yokupholisa kwensimbi.

Ukusebenza kwangempela, iphutha elikhulu lokushisa elibangelwa ukungaziphathi kahle aligcini nje ngokuthinta ikhwalithi yomkhiqizo, kodwa futhi linemiphumela ethile esobala njengokuchitheka kukagesi, isikhathi somjikelezo isikhathi eside, kanye nokuguga okwandayo kwezinto ezisetshenziswayo. kumijikelezo emine yokusakaza elandelanayo elinganiswa nge-pyrometer. Izinga lokushisa eliphakeme alikho ngaphandle kokuphindaphindeka Ngokukhethekile, uyabona ukuthi kunezipikili eziningi ezinkulu ngokwanele emissivity ku-Figure 4, okukhombisa ukuthi kukhona ukuphazamiseka okukhulu ikakhulukazi. I-spike ibangelwa ukushukuma okukhulu kwe-electromagnetic.

Le nqubo imi kanje: ukuphazamiseka ekuncibilikeni kuqinisa i-emissivity, futhi ama-pyrometers ajwayelekile akuchaza lokhu njengenani lokushisa ngokweqile; bese kuthi, njengendlela yokusabela kule nto, isilawuli sinciphisa amandla; ukunqamuka kwamandla Ngemuva kwalokho, ukuphazamiseka kwehlile, kwase kuthi, i-pyrometer ejwayelekile ithole isimo sokushisa okuphansi kakhulu, namandla abuye akhanyiswa futhi. Ukuqubuka kwamanje okuholele ekuvuseleleni izinto ezincibilikisiwe ngodlame, kwaqala umjikelezo wesikhathi, futhi ukuphazamiseka okunzima kwabangela ukugqwala kwempahla eyakhayo. Njengomphumela, ama-inclusions akhiqizwa kumkhiqizo.
