Imiyalo yokwakhiwa nokusetshenziswa kwe impahla ye-lining yesithando sokungenisa

The impahla ye-lining yesithando sokungenisa into eyomile eyenziwe nge-corundum, impushana enhle, kanye ne-chromium oxide eluhlaza. Indawo yokwakhiwa kwempahla ye-lining yesithando somlilo sokungeniswa ihlukile, futhi indlela yokwakha ibuye ishintshwe kancane.

Lapho impahla yoqweqwe lwesithando somlilo ifakwe ifindo ngaphansi kwesithando somlilo, ubukhulu bezinto ezingaphansi kwesithando somlilo zingama-280mm, okumele zigcwaliswe izikhathi ezingu-4. Lapho ubopha ngesandla, kuyadingeka ukuvimbela ukuminyana okungalingani yonke indawo. Ngakho-ke, ulwelwesi lwesithando somlilo sokungeniswa kumele lulawulwe ngokuqinile. Ubukhulu bezinto ngokuvamile abukho ngaphezu kuka-100mm isikhathi ngasinye lapho impahla yolwelwesi yesithando somlilo ifakwa ifindo, futhi ukushuba kodonga lwesithando somlilo kulawulwa ngaphakathi kuka-60mm. Impahla ye-lining yesithando sokungeniswa kufanele ijikelezwe kancane kancane esithandweni somlilo futhi amandla afanayo.

Lapho impahla ye-lining yesithando somlilo sokungeniswa ifakwe ifindo ngaphansi kwesithando somlilo ukuze ifinyelele ukuphakama okudingekayo, idinga ukufakwa isicaba ngaphambi kokuba isikhunta se-crucible sibekwe. Isikhunta se-crucible sigxilile nendandatho yokungeniswa, ilungiswe phezulu naphansi ukuze ihlanganiswe eduze nephansi lesithando somlilo esakhiwe, bese ulungisa igebe le-peripheral ukuze lilingane, ulibophe nge-wedge yokhuni, bese ucindezela isisindo sokuphakamisa esiphakathi ukuze vimbela ulayini lwesithando sokungeniswa ukuba some lapho udonga lwesithando somlilo luboshwe Impahla yefomula iyasuswa.

Lapho indwangu yesithando somlilo sokungeniswa iboshwe odongeni lwesithando somlilo, ubukhulu bensimbi yesithando somlilo sokungeniswa buyi-110-120mm, futhi indwangu yesithando somlilo kufanele yengezwe ngamaqoqo, futhi indwangu ifana futhi. ngesikhathi esifanayo. Ubukhulu bezinto zokwenziwa kolwelwesi lwesithando somlilo abukho ngaphezu kwama-60 mm isikhathi ngasinye. , Ize iguqe ngonqenqema olungaphezulu lweluphu yokungeniswa. Ngemuva kokuthi i-knotting isiqediwe, isikhunta se-crucible asidingi ukukhishwa, ukuze izinto zokugqoka zesithando somlilo zikwazi ukwenza ukushisa kwe-induction ngesikhathi sokumisa nokucwilisa.

Inqubo yokubhaka kanye ne-sintering ihlukaniswe yaba izigaba ezimbili. Ngale ndlela, isakhiwo esiminyene sokubopha sezinto zokwenziwa kolwelwesi lwesithando somlilo sokungeniswa sinamandla.

The first stage of induction furnace lining material baking: heating to 100°C at a rate of 50°C/h, holding for 2h, heating at a rate of 100°C/h to 300°C, holding for 2h, the purpose is to completely remove the moisture in the furnace lining .

Isigaba sesibili sokucwilisa i-lining material yesithando sokufakelwa: ukushisa ku-200 ℃/h kuya ku-900 ℃, ukubamba i-2h, ukushisa ku-100 ℃ / h kuya ku-1200 ℃, kubambe i-2h, isithando somlilo sokuqala sensimbi encibilikisiwe ku-1400- I-1650 ° C, ibambe ihora elingu-1, lawula Izinga lokushisa livimbela imifantu.
