Indlela yokuSombulula iNgxaki ye-Roll Cracking

Ukusetyenziswa kweimiqulukudla ngokubangelwa yimiba eyahlukeneyo, ekhokelela ekunxibeni okwahlukeneyo, ukuqhekeka, ukuchithwa, ukuqhekeka kunye nezinye iintsilelo zemiqulu, okubangela impembelelo enzulu kwinkqubo yethu yokuvelisa.Yiyiphi indlela yokujongana nayo?

Oku kulandelayo kuchaza ukusilela okuqhelekileyo kwemiqulu kunye nokuqaliswa kweendlela zonyango.

I-1.I-roller yokugqoka ihlukaniswe ngamacandelo amathathu.

Ukunxitywa komatshini kubangelwa ukungqubuzana phakathi kokubonakala komqulu kunye neengxenye eziqengqelekayo.

Ukunxitywa kwe-Thermal kubangelwa yimpembelelo yokunciphisa ubushushu obuphezulu, ukunyibilika okanye ukukhuphuka komgangatho womgangatho.

I-Corrosion wear ibangelwa yimpembelelo yekhemikhali, i-electrochemical effect, i-oxidation effect, njl.

I-2.I-Roll cracking rolling ekuveliseni iimfumba zentsimbi, intsimbi yekhadi, ukugxotha umsila kunye nezinye iziganeko, okubangelwa ukunyuka okubukhali kwiqondo lokushisa kwenxalenye yayo, isiphumo soxinzelelo lwe-thermal kunye nokuhlelwa koxinzelelo ludlula umda, obandakanya ukuqhekeka kwe-thermal.

Ulwandiso lokuqengqeleka lubandakanya ulwimi, ubushushu balo bungaphantsi kunombindi weendawo eziqengqelekayo, luya kuvelisa uxinzelelo lwe-thermal kunye noxinzelelo olukhawulezileyo lokutshintsha, okubandakanya iintanda zempembelelo, ukuqengqeleka, ngenxa yokuqengqeleka kwesitaki se-iron oxide, imikrwelo yokugada kunye nezinye izizathu. kwakhona enze iintanda.

I-3.Roll off ukubunjwa kunye nokwandiswa kwe-crack kukhawuleza, ukufikelela kubude obuthile kunye nobunzulu, kuya kubangela ukuwa.

4.Ukuqhekeka kwe-Roll

1) Uluhlu lokuphosa iintsilelo umqulu we-centrifugal casting, ngenxa ye-centrifugal vibration ivelisa ukubunjwa kunye nokucwangciswa kwe-laminar yokwahlula, okubandakanya ukwandiswa ngokukhawuleza kweentanda, okukhokelela ekuqhekekeni komqulu.

2)Rollilungiselelo iintsilelo Ukwakheka kweekhemikhali akufanelekile, izinga lokupholisa elingafanelekanga liya kukhokelela kulwahlulo lwamacandelo, umzimba we-carburization ukusilela okuphezulu kakhulu, iipropati zoomatshini kuphela ziyehla, kwaye ekugqibeleni zikhokelela ekuqhekekeni.

I-3) i-process process rolls kwi-forging pressure incinci kakhulu okanye i-deformation engekho ngqiqweni ebangelwa yi-core of rolls ayibunjwanga, eyenza i-crack ngokusebenzisa i-crystal.Iindlela zonyango lwayo.

1, Iimiquluzenziwe ngezinto ezikwazi ukumelana nobushushu kunye nobushushu obuchasayo, kunye nonyango oluhambelana nobushushu kunye nolungiselelo lwekhemikhali yonyango yamkelwe ukuba i-homogenize ilungiselelo kunye nokwandisa ukunyanzeliswa kwembonakalo, kwaye imiqulu iyahlolwa phambi kokugaya ubulukhuni kunye namaza e-ultrasonic. ukuqinisekisa ukuba akukho zintanda kunye nezinye iintsilelo.

2, Xa ujikaimiqulu, intsalela ye-oxidation layer kunye nokuqhekeka kususwe ngokupheleleyo ukuze kuncitshiswe ukuqhekeka kunye nokuchithwa kwemiqulu.3, Ulungiselelo olufanelekileyo lomjikelo wokutshintsha umqulu, imiqulu ehambelanayo, ukuzoba isicwangciso sokulungisa umqulu oneenkcukacha, ukulawula ubungakanani bokulungiswa komqulu ngaphakathi kwesikali esifunekayo, ukubekwa okufanelekileyo kwesikali sokupholisa inaliti kunye nokulawula umthamo wamanzi okupholisa ukuqinisekisa ukuba ubushushu bokupholisa imiqulu ilawulwa ngaphakathi kwesikali esiqhelekileyo.

I-4, ukomeleza ukuhlolwa kwendawo yezixhobo, ukuthintela iziganeko zezixhobo zokuqengqeleka, ukunciphisa isiphumo sentsimbi yekhadi, intsimbi yentsimbi, ukusukelana nomsila kunye nezinye iziganeko, ulawulo olungqongqo lobushushu obujikelezayo, ukuphelisa intsimbi ephantsi yobushushu ngokusila, ukuthintela ukugqithiswa kwamandla okuqengqeleka.
