Isithando somlilo sokungenisa imvamisa emaphakathi

1, ukwakheka kwemishini

The i-medium frequency induction sintering furnace ikakhulukazi yakhiwe i-thyristor intermediate frequency power supply, isithando somlilo se-hydrogen sintering kanye nesistimu yokulawula ukushisa okuzenzakalelayo. Ukwakheka kwengxenye ngayinye imi kanje:

1. I-thyristor intermediate frequency power supply iqukethe i-KGPS-250/2.5 250KW 2.5KHz iKhabhinethi yokuphakela amandla kagesi, ikhabethe le-capacitor yokushisisa kagesi, imigoqo yethusi exhumayo nendlela yenjini;

2. Isithando somlilo esishisayo sakhiwe ngomzimba wethangi, i-inductor, i-alumina, i-zirconia refractory material, ibhodwe le-tungsten crucible, ithange lamanzi elibuyayo elivulekile, ibhodi lokulawula ukugeleza kwe-hydrogen / nitrogen, kanye ne-gantry;

3. Uhlelo lokulawula izinga lokushisa oluzenzakalelayo luncoma izindlela ezilandelayo:

I-4.1, isistimu yokulawula ukushisa okuzenzakalelayo ilinganiswa yinzwa ye-fiber optical, elawulwa umlawuli wokushisa, futhi irekhodwe yirekhoda.

I-2, indlela eyinhloko yokukhetha izinkomba zobuchwepheshe zesithando somlilo se-inter frequency induction sintering

1, ububanzi bangaphakathi: φ 400 × 750 × 16

2, impahla yangaphakathi: i-tungsten

3, izinga lokushisa eliphakeme kakhulu le-sintering: hhayi ngaphansi kuka-2200 °C

4, ukunemba kokulawula izinga lokushisa: ± 10 °C

I-5, amandla kagesi kagesi: 380V, 50Hz, isistimu yezintambo ezine ezinezigaba ezintathu

6 , imvamisa yokusebenza: 2500Hz

I-7, isilinganiso sokushisa esizenzakalelayo, isibonisi, ukurekhoda okuzenzakalelayo

8. Ukuvikelwa kwe-hydrogen yesithando somlilo, i-outlet eguquguqukayo egelezayo, ukukhishwa kwe-slag

I-9, nge-overcurrent, overpressure, ukuntuleka kwesigaba, ukucindezelwa kwamanzi okwanele, ukuvikelwa okungaphezulu kwezinga lokushisa

10, inombolo yemishini 1

4 , sintering furnace structure description

Imbobo evikela ukuqhuma: ulwelwesi olungaqhumi, i-silicone yerabha gasket kanye ne-over-pressure hydrogen outlet.

Imbobo yokuhlola eqhumayo: ukuthola indawo yokugezela ye-hydrogen esithandweni somlilo.

Umzimba wesithando somlilo: izingqimba ezimbili ngaphakathi nangaphandle, ungqimba lwangaphandle luboshwe ngempahla yokushisela engu-10mm engu-16Mn. Ungqimba lwangaphakathi oluwugqinsi oluwu-8mm lushiselwe i-1Cr18Ni9Ti, imigoqo eqinisayo eyengeziwe, ukuvimbela umfutho wamanzi owedlulele welayini yomlilo ekhubazekile izendlalelo zangaphakathi nezingaphandle, phakathi nangaphansi.

Isembozo sesithando somlilo: isakhiwo saso siyafana nomzimba wesithando somlilo.

Isembozo selensi: Isakhiwo esijikelezayo sakhelwe ngaphakathi ukuze kuvinjelwe ukungcoliswa ilensi yintuthu esithandweni.

Imithombo ye-hydrogen ne-nitrogen.

I-Flange lens: ifakwe i-silicone gasket yerabha ethintana ne-lid flange, i-quartz lens egxilwe ku-flange engenhla, isembozo simane sihlukaniswe iphiko le-lens flange lingahlanzwa.

Ubakaki wokulinganisa izinga lokushisa: Engeza inhloko yokulinganisa izinga lokushisa le-infrared, ungenza ukulungisa okunezinhlangothi ezintathu ukuze kuhloswe.

10, isivalo sesivalo

11, indawo yokukhipha iziko

I-12, ikhava yesithando somlilo ephakamisa isilinda esijikelezayo se-hydraulic: isembozo somlilo esakhelwe ngaphakathi siphakamisa umkhono ojikelezayo, isembozo sesithando somlilo singashintshwa ngo-20mm bese sizungezisa amadigri angu-0 ~ 90, isembozo somlilo siyakhuphuka ngesikhathi senqubo yokujikeleza.

I-13, i-Pedal foot Pedal: ihlelwe ngezigaba ezimbili zokungahambi kahle, ezingasetshenziswa ukuze abasebenzi bakhiphe izinto. Ngenxa ye-squat ephezulu, ama-pedals ahlelwa abe yizingqimba ezimbili, ama-pedals amamitha amathathu esitezi ngasinye, futhi ungqimba olungezansi luwukuba abasebenzi bathathe ungqimba olungaphezulu. Sebenzisa, ungqimba olungezansi lusetshenziswa ngabasebenzi ukuthatha ungqimba olungezansi. Ngemva kokusetshenziswa, phinda i-pedal yonyawo ukuze uyivimbele ukuthi ingashisiswa inzwa.

14 , imbobo yesithando somlilo

15. I-hydrogen, i-nitrogen, i-slag, nezindawo zokukhipha amanzi.

16, ukutywinwa kwe-thermocouple okuneshehethi kusho okufakwe umucu werabha we-silicone, i-flange evalayo.

I-17, i-armored thermocouple protection tube: i-thermocouple eyakhelwe ngaphakathi.

18, insika ye-porcelain eboshiwe

29 , i-porcelain pad bushings kanye namawasha e-porcelain: ukufakwa kukagesi.

20, ikhoyili yokungeniswa.

21 , ipuleti lokusekela lomphongolo wensimbi engagqwali.

22 , i-tungsten 坩埚: φ 400 × 750 × 16

23 , isitini esiphikisayo se-zirconia

24, isitini esiphikisayo se-aluminium oxide

25, phakathi nendawo yokungena injini kanye ne-flange, ngaphakathi kwerabha ye-fluoro, i-O -ring kanye ne-copper tube wire kanye namanzi okupholisa.

I-27, isiteji: ukuphakama kwesiteji kusuka endaweni yomsebenzi ophansi 1 8 M, kusukela ekuphakameni kwesithando somlilo 0.6M, 2.9M ngaphandle kocingo olubiyelwe ukuphakama okuphelele, isethi ephakathi Buti, i-worktop Buti kanye ne-steel plate surface enephethini. Kungene, okungasheleli. Ibhokisi lokulawula i-hydrogen ne-nitrogen lihlelwe ohlangothini lwesitebhisi sesinyathelo, futhi imitha yokugeleza kwe-rotor kanye ne-valve yokushintsha igesi kuhlelwa ngaphakathi ukuze kushintshwe igesi futhi kulungiswe izinga lokugeleza. I-gantry yenziwa itholakale futhi ihlukaniswe ngobubanzi bomzimba wesithando somlilo, futhi umzimba wesithando somlilo ufakwa. Uma ususendaweni, vala isitendi bese uqinisa ngamabhawudi.

5, medium frequency induction induction sintering isithando somlilo isici

Isici sokushisa se-tungsten crucible sisetshenziselwa ukushisisa i-tungsten crucible ngokushisa okungeniswayo, bese into ezoshiswa iyashiswa.

6, medium frequency induction induction sintering esithandweni refractory

I-refractory material phakathi kwe-inductor ne-tungsten crucible iqukethe i-aluminium oxide ne-zirconium oxide. Njengoba ungqimba lwangaphakathi luseduze ne-tungsten crucible futhi izinga lokushisa liphezulu, i-zirconia ene-refractoriness ye-2600 ° C ikhethwa njengento ephikisayo. Njengoba ungqimba lwangaphandle lunomphumela wokushisa wokushisa we-zirconia njengento ephikisayo futhi izinga lokushisa liphansi, i-aluminium oxide ene-refractoriness ephansi kanye nephuzu lokuncibilika lika-2050 ° C lingasetshenziswa njengento ephikisayo. Ngale ndlela, kokubili umphumela wokushisa umlilo nokushisa kungafinyelelwa, futhi izindleko zemishini zingancishiswa ngokufanelekile.
