Medium frequency kudziyisa choto zvinodiwa zvehunyanzvi

1. Thyristor yepakati frequency inverter:

1.1 Nechoto chakazara chinotonhora chekutanga basa, tanga chiyero chekubudirira: 100%; inopisa zvinhu 100%. Iyo blast furnace inotanga kupisa chinhu chechitatu kusvika pakupisa tembiricha. Uye inogona kugadzirwa kusvika kune yekupedzisira zvinhu.

1.2 Simba remagetsi rine zvikamu zve 500 kw, uye kuwandisa kunobvumirwa kuva 20% kwenguva pfupi.

1.3 yakayerwa simba rekubuda re500 kw rinomhanya simba chinhu pamusoro pe0.9.

1.4 Zvikamu zvikuru senge thyristors muIF inverter kabhineti uye zvikamu zvikuru zvemutsetse wese zviri nani kutengeswa kubva kunze kwenyika kana yepamba ine mukurumbira mhando yepamusoro michina. Zvese dhizaini zvikamu zvinoda kutsiviwa neimwe nhanho nekuda kwekunetseka kwekutenga, kuve nechokwadi chekushanda kwakagadzikana uye kwakavimbika kwemidziyo.

1.5 yepakati frequency induction heater ine basa rekuchengetedza kupisa (yakaderera frequency kushanda kwepakati frequency simba rekupa).

1.6 Mushure mekupisa, zvivharo zvakasiyana-siyana zvinosvika pakupisa kwekushanda kwezvinhu zvakasiyana ( 1150 ° C) , uye zvinhu hazvinamatira.

1.7 Circuit chimiro: parallel inverter.

1.8 Kana iri grid voltage kuchinja kwe15%, iyo IF inobuda voltage fluctuation haina kupfuura ± 1%.

1.9 brass dual reactor configuration, yakabatana kune yemukati-sectional nzvimbo yemhangura yakakura zvakakwana kuderedza kupisa.

2. Induction hita:

2.1 Kufanana kwekushisa: Kusiyana kwekushisa kwepamusoro pemoyo webillet kunoderedzwa kusvika padiki painobudiswa.

2.2 Iyo sensor inogadzirwa neyemhando yepamusoro knotting, uye yakajairika hupenyu hweiyo sensor coil inodarika makore matatu. Iyo sensor lining ine yakajairika sevhisi hupenyu hweanopfuura gore rimwe.

2.3 Iyo yemukati inotungamira njanji ye sensor ine kupfeka-inodzivirira zvinhu.

2.4 uchishandisa parallel inductor dhizaini, iyo isina chinhu inowedzerwa zvishoma nezvishoma kubva kumagumo ekudya kusvika kune yekuburitsa tembiricha kuti ive nechokwadi chekuti iyo isina kuvharwa haiburitse madiki-akatsemuka mukupisa, kupisa kwakanyanya uye kumwe kukanganisa.

2.5 Iyo inductor coil, bhazi bhara uye waya dzinobatanidza dzine nzvimbo yakakura yekuyambuka-chikamu kudzikisa kupisa kupisa.

2.6 Kubatana kwemukati kweinductor coil kwakavimbika, iyo inductor inogadzirwa zvakanyatsoenderana nezvinodiwa nemaitiro, uye iyo yepamusoro-yekumanikidza leak bvunzo inoitwa isati yaungana.

3. Temperature control system

3.1 Thermometer:

3.1.1 American Raytheon infrared thermometer inogona kushandiswa pakakwirira kubata uye kugadzirisa otomatiki. Muchikamu che1150 ° C, kukanganisa kwekuyera kwekushisa hakusi kudarika ± 0.3%, uye kudzokorora kurongeka hakusi kupfuura ± 0.1%.

3.1.2 Chiyereso chekuyeresa tembiricha hachikanganiswa nepamusoro pe oxide scale, huruva, chiutsi uye mhute yemvura.

3.1.3 Seta thermometer pachiteshi chekuburitsa kuti uve nechokwadi chekuvhara-loop control;

3.2 Kudzora chiridzwa: Iyo tembiricha yekudzora sisitimu ine “PID” inogadzirisa basa uye yakavharwa-loop kutonga kwekushisa kwechoto.

Kudzora system control musimboti:

Power regulation control panguva yekupisa:

Mukugadzirisa kupisa workpiece, kugadzirisa simba kunonyanya kuenderana nezvinhu zviviri.

Iyo tembiricha inodzorwa mukati yakavharwa loop zvinoenderana neyakagadzika tembiricha tembiricha.

Zvinoenderana neinomhanya bhiti inodiwa yeworkpiece, iyo yekumhanyisa inodiwa inosangana neyakavharwa loop kugadzirisa kwesimba.

4. Electrical control system:

4.1 Iyo yakazara seti yemidziyo inogona kudzorwa pamberi pekutonga kabati kana munzvimbo yekushanda.

4.2 inogona kuona zvizere otomatiki, semi-otomatiki, yemanyorero ekugadzirisa basa modhi.

4.3 Kudzora chikamu Wedzera PLC kune man-machine interface, isa parameters munguva chaiyo, kuratidza simba, voltage, ikozvino, tembiricha uye mamwe ma parameter, intuitive uye yakavimbika.

5. Matanho ekuchengetedza:

5.1 Equipment magetsi ekubatanidza zvikamu zvine yambiro inodiwa (zviratidzo zvemheni, yambiro, partitions, nezvimwewo), chengetedzo nekudzivirira kuchengetedza kuchengetedza uye kuchengetedzwa kwevashandisi.

5.2 Kupindirana uye kudzivirira kuita kweseti yese; emergency stop, over voltage, over current, phase loss, inverter failure, voltage cutoff, current cutoff, over tembiricha yezvikamu uye under pressure and cooling of cooling system, tembiricha yemvura yakakwira (mvura yega yega inodzoka) Matavi ese ane tembiricha yekuona. ), uye nzira inotevera (isingasviki maminitsi gumi nemashanu ekuderedza simba rekukanganisa, kudarika maminitsi gumi nemashanu ekuvhara kukanganisa) uye kumwe kupindirana, kukanganisa alarm, kuongorora kukanganisa, nezvimwewo, kushanda kwakakwana, kwakavimbika. Iyo inovimbiswa kuti iyo michina haizokuvadzwa, uye kukundikana kweiyo materialization mune induction heater uye kuchengetedzwa kwemunhu kuchaitika.

5.3 Iyo yese seti yemidziyo yakavimbika uye ine nguva inonzwisisika, iyo inogona kunyatso dzivirira kukuvadzwa kunokonzerwa nekusashanda zvakanaka kumidziyo uye muviri wemunhu.

5.4 Kugadzira uye kuisirwa kunoitwa zvinoenderana neMachina Indasitiri Yekuchengetedza Kuongorora Mayero eBazi reMachina Indasitiri.

5.5 Iyo inogadzirwa zvinoenderana neyakajairwa nyika induction yekupisa choto mwero uye inosangana nedziviriro yenyika uye kuchengetedza zviyero.
