Ungalufaka kanjani ifindo ulwelwesi lwesithando sokushisa se-induction?

1. Ukwakheka kwezinto zokugqoka zesithando sokushisa sokungeniswa: ngokuvamile kuhlanganiswe nesihlabathi se-quartz. Ukuqina kolwelwesi lwesithando somlilo bungancishiswa, ukusebenza kahle kukagesi kungathuthukiswa, nokusebenza kahle konke kungaba phezulu. Isici esibaluleke kakhulu sokusetshenziswa kwamandla okuphansi kwama-diameters amancane ukuthi ubukhulu bendwangu yesithando somlilo abukwazi ukwenziwa mncane kakhulu. Lapho ushisisa ama-workpieces ama-diameter ahlukene esithandweni sokufakwa esithandweni esifanayo, ukusetshenziswa kwamandla kuhlala kuphansi uma ububanzi bukhulu, futhi ukusetshenziswa kwamandla kuphezulu lapho ububanzi buncane. . Le lining yokushisisa isithando somlilo inezici zokusebenza okuhle kakhulu kokwakhiwa, amandla aphezulu, i-anti-cracking, i-fluidity ephezulu kanye nokumelana nokugqoka okuphezulu.

2. I-lining yesithando sokushisa sokungeniswa ifaneleka ukubumba ukushisa, ukucisha insimbi kanye nokushisa okushisayo kanye nokushisa kwesitembu sesithando somlilo. Izinga lokushisa elisebenzayo liyi-1300-1400 ° C. Ingasetshenziswa izinyanga ezingu-3-8 ngokuthululwa okukodwa nokubopha, okuthuthukisa ngokuphumelelayo isithando sokushisa sokungeniswa. Impilo yesevisi, yehlisa izindleko zesithando somlilo. Ngenxa yokuthi uhlaka lwesithando somlilo lusetshenziselwa ikakhulukazi ukuthintana okuqondile nokushisa kwensimbi eyindilinga, kuyadingeka ukuthi izinto ze-granular kanye ne-powdery kufanele zibe nokuqina kwevolumu ephezulu, ukubumbana nokumelana nokugqwala, kanye nesithando sokushisa esingeniswayo kufanele sibe nokufakwa.

3. Ulwelwesi lwesithando sokushisa lokungeniswa kufanele luvinjwe ukuba lungawi futhi luqhekeke ngesikhathi sokusetshenziswa. Isizathu sokuqhekeka ukuthi izinto zokusetshenziswa azilungile ngokwanele. Impahla yolwelwesi ngokuvamile iwusimende ongashintshi. Uma usimende usumunca umswakama, uzokwakhiwa ube yimpuphu, futhi uzowa ube yizicucu. Inqubo ayikho endaweni. , Usimende we-Refractory ufana nosimende wokwakha ojwayelekile. Idinga ukugcinwa futhi isikhathi ngeke sibe sincane. Lokhu kunakekela kuwukunakekela endaweni enomswakama. Isikhathi sokunakekela singamahora angama-48. Zomisa futhi ungabhaki izindlela ezimbili. Ukuze ube nempilo ende yenkonzo yesithando somlilo, ukomiswa kocingo lwesithando somlilo kubaluleke kakhulu. Umongo ukoma kancane. Uma ukoma ekushiseni okuphansi isikhathi eside esingu-36h, ukukhuphuka kwezinga lokushisa kokuqala kufanele kube kancane kakhulu.

4. Ulwelwesi lwesithando sokushisa lokungeniswa lusebenzisa izibambi zokwakhiwa kwe-corundum-based casting casting refractories; lolu hlobo lwezinto lisebenzisa i-corundum ehlanzekile njengento eyinhloko futhi ngokusebenzisa ukulinganisa usayizi wezinhlayiyana ezifanele, impahla inezici zokumanzisa okuphezulu, ukwakhiwa okulungile, kanye nevolumu ephezulu. Izinzuzo zokuzinza; isikhathi sokubhaka esifushane, amandla aphezulu, ukumelana nokugqokwa okuhle, akukho ukuqhekeka, nempilo ende yesevisi ingasetshenziswa kalula nasezindaweni ezizungezile zamakhoyili ahlukahlukene.

Lesi sithando sokushisa esingefanisiwe esisebenza kahle esithela izinto zokufiphaza, lapho sisetshenziswa, engeza amanzi amaningi ukuze anyakaze ngokulinganayo futhi uwathele ngqo esithandweni sokushisisa sokungenisa. Imishini yekhoyili ye-induction yenza yonke into eqinile ngekhoyili. , amandla aphezulu, ukumelana nokugqoka, ukusebenza kahle kokugeleza, impilo ende yesevisi nezinye izici ezibalulekile, ezisetshenziswa kabanzi ezithandweni zokushisa zokungeniswa, iziko lokushisa eliphakathi nendawo eliphakathi, i-induction heat linings.

5. Ukukhethwa kwe-ejenti ebophezelayo lapho isithando somlilo sokungeniswa sifakwe ifindo kufanele sifaneleke, abanye bangasebenzisi i-ejenti ebophezelayo, kanti abanye bengeza kuphela inani elincane lokugeleza. Izinto ze-Acid ramming zivame ukusetshenziswa njengezibophezelo ezifana ne-sodium silicate, i-ethyl silicate, i-silica gel, njll. Phakathi kwazo, izinto ezomile ze-ramming zisebenzisa i-borate; izinto ze-alkaline ramming ngokuvamile zisebenzisa i-magnesium chloride ne-sulfate; Ikhabhoni ephezulu ingakha izinto eziphilayo eziboshwe ngekhabhoni kanye nezibophezelo zesikhashana emazingeni okushisa aphezulu. I-ramming material eyomile yengezwa ngenani elifanele lokugeleza okuqukethe insimbi. I-Chromium ramming materials ivamise ukusetshenziswa njengezikhonkwane zikamango.

6. Ngemuva kokuthi ulayini lwesithando sokushisa lokungeniswa seluboshwe ifindo, i-inductor esanda kwenziwa efakwa ekukhiqizeni kufanele ibhakwe ngamandla aphansi (imvamisa cishe ama-30KW) ngemuva kokufakwa amandla, futhi into yokushisisa kufanele ibekwe endaweni yokushisisa yokungeniswa. isithando somlilo amahora angu-2. mayelana. Isizathu siwukuthi umenzi wesithando sokushisa we-induction kumele adlulise amanzi kunzwa ngesikhathi senqubo yokulungisa iphutha. Ngemva kokulungisa iphutha, kufanele kube namanzi asele kushubhu yethusi yenzwa. Ikakhulukazi ebusika, kungase kwakheke iqhwa elincanyana kakhulu. Ngakho-ke, inzwa kufanele ibe manzi. Ukuze kuqinisekiswe impilo yesevisi yomugqa wesithando somlilo, okusanda kufakwa ekukhiqizeni i-inductor kufanele kubhakwe ngamandla aphansi, bese uqala ukukhiqiza ngamandla amakhulu ngemva kwamahora angu-2.

7. Kunezinhlobo ezimbili eziyisisekelo zamafomu okuhlanganiswa kokufakwa kwesithando somlilo we-induction ukushisisa isithando somlilo, enye i-knotted furnace lining, kanti enye ihlanganiswe umugqa wesithando somlilo. Lokhu esikhuluma ngakho lapha ulayini wesithando somlilo esinamafindo, kodwa kungakhathaliseki ukuthi ulayini lwesithando somlilo olunamafindo noma ulwelwesi lwesithando somlilo oluhlanganisiwe, luzoshintsha lapho lusebenza ekushiseni okuphakeme isikhathi eside (ikakhulukazi ukunwetshwa okushisayo nokufinyezwa okubandayo kanye ne-oxidation). Uma isetshenziswe ngendlela engafanele, isenzakalo sokushayisana kwezinto ezishisayo kanye nolayini lwesithando somlilo we-extrusion nakho kuzokwenzeka. Ngakho-ke, ukusetshenziswa kwesithando somlilo kunesikhathi esithile. Lokhu ikakhulukazi kuncike esimweni ngesikhathi sokusetshenziswa.

8. Uma i-lining yesithando sokushisa sokungenisa i-induction isetshenziswa, uma kwenzeka ukuqhekeka, uma ulwelwesi luboshwe, ukuqhekeka kufanele kugcwaliswe ngezinto zokubopha ngesikhathi uma ukuqhuma kungadluli i-2mm. Uma umfantu udlula u-2mm, ulwelwesi kufanele luboshwe kabusha; uma kuwulwelwesi oluhlanganisiwe kufanele kushintshwe. Ngakho-ke, umsebenzisi kufanele athathe izinyathelo ezidingekayo ngokusho kwesimo sangempela, futhi akumele enze ngokuxhamazela, abangele imiphumela engadingekile futhi ashise inzwa.

Ngesikhathi senqubo yokushisa yenzwa yokushisa yokufakelwa kwesithando somlilo, isikhumba esiningi se-oxide esiwa emsebenzini esishisayo sizoqoqana kunzwa. Uma uhlaka lwesithando somlilo lonakalisiwe, noma kukhona ukuqhekeka noma ukuqhekeka, uma kungahlanjululwa ngesikhathi, kulula ukubamba umlilo, okuholela ekuvikelweni okudlulele kokunikezwa kwamandla okuvama okuphakathi, futhi okwesibili, kulula ukudiliza ikhoyili ye-inductor futhi ibangele ukujikeleza okufushane phakathi kokujika kwe-inductor. Ngakho-ke, isikali se-oxide esithandweni sokungeniswa kufanele sihlanzwe okungenani kanye njalo lapho kushintshwa (amahora angu-8).
