I-intermediate frequency induction heat ye-copper wire annealing imishini

1 , Uhlolojikelele:

I-intermediate frequency induction heat wire yethusi (ithubhu yethusi) imishini yokudonsa ifanele ukuxhunywa ku-inthanethi kocingo lwethusi (umgodla we-alloy wethusi wangaphandle). Ukujula kokungena nobulukhuni kuhambisana nezidingo ezithile zamakhasimende ukuze kuzuzwe ukukhishwa kwengcindezi nokuthambisa ingxubevange yethusi. Inhloso yomgodla wangaphandle.

Isingeniso semishini Isethi ephelele yezinto zokusebenza iklanywe futhi yakhiwe ngokuya ngesakhiwo se-mechatronics. Phakathi kwazo, ukunikezwa kwamandla okuvama okumaphakathi kuyisethi ye-6- pulse thyristor KGPS200KW/8KHZ yamandla amaphakathi aphakathi nendawo, umthwalo uyisethi yesithando sokushisa esingenisa uchungechunge lwe-GTR, futhi okokusebenza kufakwe isethi ye-capacitor bank yesinxephezelo samandla asebenzayo. . Idivayisi iklanywe ngezinkinobho zokulungiswa kwamandla okwenziwa ngesandla kanye ne-othomathikhi, phakathi kwazo okuzenzakalelayo imodi yokulawula iluphu evaliwe. Ikhonsoli yokulawula yangaphandle ilawulwa yi-PLC (Siemens) nesikrini sokuthinta. Isikrini sokuthinta singafaka kalula amapharamitha wokushisisa, njengokucaciswa kwentambo yethusi, isivinini sokushisisa, izinga lokushisa le-anneal, njll. Ngemva kokufaka amapharamitha, isistimu yokulawula iluphu evaliwe yezinga lokushisa eliphakathi nendawo eliphakathi lizolungisa ngokuzenzakalelayo amandla okukhiphayo, ngaleyo ndlela i-Meet. izidingo zokukhiqiza. Uma isixhumanisi esithile ekukhiqizeni sihluleka, ukunikezwa kwamandla okuvama okumaphakathi kungavalwa ngokuvumelana nezinga lokushisa elimisiwe ukuze kugwenywe ukushisa ngokweqile ucingo lwethusi. Izinto ezisetshenziswayo zibekwe ngokwezidingo zomsebenzisi, zibheke okokusebenza ukusuka kwesobunxele kuye kwesokudla, ithebula lokusebenza libekwe ngasemishinini emikhulu, elivumela opharetha ukuthi abheke isimo sokukhiqiza futhi enze kube lula ukulungiswa kwemingcele.

Ukuvikela ukuphepha Izinto ezisetshenziswayo zinezinyathelo eziphelele zokuvikela zokuphepha, njengokuvikela ukushoda kwamanzi, ukuvikelwa kokuntuleka kwamanzi, ukuvikeleka ngaphezu kwamanje, ukuvikelwa kwamandla kagesi, ngaphansi kokuvikelwa kwamandla kagesi, ukuvikelwa kwezinga lokushisa eliphezulu lamanzi, njll., futhi kukhona idivayisi ye-alamu ezwakalayo nebonwayo ye-alamu amaphutha. Izisetshenziswa zilungiswa ngokuya nge-200KW, zishiya umkhawulo wamandla owanele ukuze kuqinisekiswe ukukhiqizwa okuqhubekayo nokuzinzile kwemishini amahora angama-24. Wonke ama-conductor avuliwe afakwe ebhokisini lokulawula likagesi elinengidi, futhi kunezikhumbuzo zokuphepha ezidonsa amehlo, ngakho azikho izingozi zokuphepha zikagesi ezizokwenzeka. Idivayisi ngayinye exhumayo ingagwema ukulimala kwemishini noma izintambo zethusi ngenxa yokusebenzisa kabi ngesandla.

Isakhiwo semishini Isethi ephelele yemishini ihlanganisa indawo engaba ngu-2000*1500mm, enobude obuyisikhungo obuyi-1000mm. Ukunikezwa kwamandla kuhlanganiswe nomzimba wesithando sokushisa, futhi ama-bolts okunweba asetshenziselwa ukulungisa. Imishini yakhelwe nge-console yangaphandle, engahlelwa ngokuthanda kwayo ngokuya ngemibandela yesayithi, elungele ukusebenza. Ukufakwa kwemishini kulula futhi kuyashesha. Abasebenzisi badinga kuphela ukuxhuma amapayipi okungenisa amanzi namapayipi okukhipha amanzi ngepayipi lamanzi lokungena kanye nokuphumayo wempahla (ubhobhobhobhosi owodwa endaweni ngayinye yokungena namanzi), futhi baxhume izintambo ezine zezigaba ezine ekupheleni kwempahla.

ipharamitha lobuchwepheshe

2 .1 amapharamitha zobuchwepheshe

Izinto ezisetshenziswayo: ngocingo oluphansi (ngaphakathi yi-conductor ewumgogodla we-copper stranded, kanti ngaphandle imbozwe ngokuqinile nge-alloy sheath yangaphandle yealloy)

Indlela ye-Annealing: Ukushisa kwe-inthanethi okuqhubekayo okuqhubekayo

Ukucaciswa kwezinto ezibonakalayo: φ 6- φ 13mm, ukujiya kodonga 1mm

2 .2 izimfuneko zobuchwepheshe eziyinhloko zokushisisa

Izinga lokushisa lokuqala: 20 ℃;

Izinga lokushisa le-Annealing: liyalawuleka futhi liyalungiseka ngaphakathi kwebanga lika-600 ℃; ukunemba kokuhlolwa kwezinga lokushisa kongqimba lwengxubevange yethusi ngu-± 5 ℃, futhi ukunemba kokulawula izinga lokushisa kokushisisa kokungeniswa kungu-± 20 ℃.

Ukujula kokushisa: 2mm;

Isivinini somugqa wenqubo: ngaphakathi kwe-30m / min (isivinini esikhulu somugqa asiphezulu kune-30m / min);

Ubude besikhungo somugqa wokukhiqiza: 1m;

2.3 Ukukhethwa kwezobuchwepheshe kwemishini ephelele

Isethi ephelele yemishini ihlanganisa isistimu yokulawula ukunikezwa kwamandla okuvama okumaphakathi, isistimu yokulinganisa izinga lokushisa kwefayibha ekude ye-infrared, isistimu yokulawula izinga lokushisa elivaliwe, ibhange le-capacitor yesinxephezelo samandla asebenzayo, umzimba wesithando sokushisa ongeniswayo, njll.

Isistimu yokulawula amandla efrikhwensi emaphakathi:

2.3.1 Ukunikezwa kwamandla okuvama okumaphakathi kuyidivayisi eshintshashintshayo ye-thyristor, i-voltage yokufaka ngu-380V , 50Hz , futhi amandla okukhiphayo ngu-200KW. Amandla angalungiswa ngesandla noma ngokuzenzakalelayo ngokuvumelana nezinga lokushisa elibekiwe. Ifrikhwensi yokuphumayo ngu-8KHz (ukulandelela imvamisa okuzenzakalelayo). Umbala wekhabhinethi unqunywa ngokwezidingo zomsebenzisi, usayizi wohlaka 2000 × 1500 × 1300mm, kanti ukuphakama kwesikhungo kungu-1000mm.

2.3.2 Uhlobo lwe-cartridge ehlanganisiwe ye-silicon rack

Ingxenye yokubuyisela kanye ne-inverter ye-thyristor yamukela uhlaka lwakamuva lwe-silicon oluhlanganisiwe olunohlelo lwelungelo lobunikazi. Le ndlela yokufaka yenza i-disassembly kanye nokuhlanganiswa kwe-thyristor kube lula kakhulu futhi kwesayensi. Uma ushintsha i-thyristor, vele uyikhulule Ibhawodi eliqinisayo lingangena esikhundleni sanoma iyiphi i-elementi ye-thyristor ekuhlanganiseni. Ngaphezu kwalokho, le ndlela yokufaka inciphisa ngokugcwele umthamo wengxenye ye-SCR, engagcini nje ukwandisa indawo yokusebenza kukhabhinethi kagesi, kodwa futhi inciphisa kakhulu ukulahlekelwa komugqa.

2.3.3 Umthamo omkhulu we-DC smoothing reactor

I-reactor eshelelayo ibaluleke kakhulu ekunikezeni amandla aqinile, inemisebenzi emibili. Okokuqala, yenza i-current output ye-rectifier bushelelezi futhi izinzile. Okwesibili, lapho i-thyristor ye-inverter ifushane, izinga lokukhula kwe-short-circuit current kanye nobukhulu bezinga eliphezulu le-short-circuit current lilinganiselwe. Uma idizayini yepharamitha ye-reactor yesihlungi ingenangqondo, into esemqoka ayilungile noma inqubo yokukhiqiza ingeyinhle ngokwanele, izoba nomthelela omkhulu ekuthembekeni kokusebenza kokunikezwa kwamandla okuvama okumaphakathi.

2.3.4 I-SCR yomthamo omkhulu

Ukuze kuqinisekiswe ukuthembeka kokusebenza kwemishini, kokubili i-rectifier ne-inverter thyristors zisebenzisa i-Xiangfan yamandla amakhulu e-KP esesiteshini se-KK kanye ne-silicon ye-KK ukuze kuqinisekiswe ukusebenza okuzinzile kwesisetshenziswa.

2.3.5 Sebenzisa izintambo zesinxephezelo eziwuchungechunge nezihambisanayo ukuze kuncishiswe ukulahleka kwezintambo zikagesi

Ukuze kuncishiswe ukulahlekelwa kulayini wokudlulisa imvamisa emaphakathi, i-capacitor yesinxephezelo ye-inverter ixhunywe ochungechungeni kanye nefomu elihambisanayo lokuphindwa kabili kwe-voltage.

2.3.6 Amapharamitha esekethe enkulu kanye nesisekelo sokukhetha ingxenye

Amapharamitha alinganiselwe esekethe eyinhloko yokunikezwa kwamandla kwefrikhwensi emaphakathi aboniswa kuthebula elilandelayo :

I-inductor yakhiwe ngegobolondo lesithando somlilo, ikhoyili yokungeniswa, iqoqo lamanzi lensimbi engenasici kanye nolayini lwesithando somlilo. Ikhoyili ye-induction ihlanganiswa nemingcele yeshubhu ye-alloy yethusi ehlanganisiwe ukuze kuthuthukiswe umklamo ngesofthiwe yekhompyutha ekhethekile futhi iwenze uhlanganiswe nolwazi lwangempela. Ingaqinisekisa ukusebenza kahle kakhulu kokuxhumana kwe-electromagnetic ngaphansi komthamo ofanayo. Amakhoyili angeniswayo ane-99.99% yentambo yethusi engunxande ye-T2 eyenziwe, ikhoyili yokungenisa insulating yangaphandle ye-electrostatic spray inqubo ungqimba oluvikelayo lwe-epoxy resin lwamandla aphezulu, ungqimba oluvikelayo olumelana nengcindezi lungaphezu kuka-5000V.

Ungqimba lwangaphakathi lwekhoyili ye-induction lwenziwe nge-white corundum lining, futhi ingaphandle le-lining naphakathi kwamakhoyili ahlanganiswe nosimende ophikisayo (i-American Union Mine), engadlala indima ekufakeni nasekugcineni ukushisa. Ngesikhathi esifanayo, amandla e-white corundum lining ayanda ngokuqhubekayo, ukugwema ngokuphumelelayo ukulimala kocingo lwethusi ku-lining.

Wonke amanzi angaphakathi nangaphandle kwenzwa aqoqwa abe yizicupho ezimbili zamanzi zensimbi engagqwali, ezixhunywe kumapayipi amakhulu okungena namanzi. Umqoqi wamanzi wensimbi engenasici muhle futhi uyasebenza, ongagwema ngokuphumelelayo umthelela wokuchithwa kokushisa kwekhoyili ye-induction ngenxa yokugqwala kwepayipi lamanzi nokuvinjelwa komzila wamanzi.
