Isantya esiphezulu Steel Mill Rolls forIshiti leMetal eliqengqelekayo kunye nokuSetyenziswa kweBillet Mill

Imiqulu yentsimbi yokusila enesantya esiphezulu, eveliswa yinkqubo yokuphosa ye-Centrifugal ethe tyaba, zonke ziyimiqulu edibeneyo enesantya esiphezulu sentsimbi njengomaleko womsebenzi kunye nentsimbi ye-nodular njengondoqo. Izinto zemiqulu ziqulethe izinto ezininzi ezidibeneyo ezifana ne-Mo, V, W, Cr njl njl. I-eutectic carbides ephezulu kunye ne-carbides yesibini, njenge-MC, i-M2C, i-M6C isasazwe ngokulinganayo kwi-matrix epholileyo ye-martensitic, yenza ukunxiba kunye nokumelana nokuqhekeka kwe-thermal. kuhle kakhulu. Ngaphandle koko, ukumelana nokurhabaxa komphezulu nako kulungile. Kwimeko yokutshisa okutshisayo, iindawo zoqhagamshelwano phakathi kwentsimbi yentsimbi kunye nemiqulu yomsebenzi zingenza ifilimu edibeneyo ye-oxide edibeneyo kwi-roll surface, edlala indima enhle kwiimpawu zokunxiba kunye nomgangatho we-strip surface. Iiroli ezidumileyo zisetyenziswa kakhulu njengee-work rolls kwi-hot strip mill kunye neendawo zokugqiba zebar mill; amakhonkco eemill zecandelo lehlabathi jikelele kunye neendawo zokugqiba ze-high-speed bar mills.

Ngesiqhelo, senza olu hlobo lomqulu nge-static cast kunye ne-centrifugal cast. Sincoma ukusebenzisa i-centrifugal cast rolls ekusebenzeni ngcono xa i-groove kumzimba we-roll ayinzulu kakhulu. Nge-alloy engaphezulu eyongeziweyo, sinokufumana i-microstructure equkethe i-spheroidal graphite, i-pearlite kunye ne-primary carbide uhlobo lwe-M3C ukuya kwi-30%. Ngeli xesha, undoqo womqulu usahlala womelele kakhulu kunye nesixa esikhulu segraphite espheroidal kwimatrix yeferrite. Xa i-groove kumzimba we-roll inzulu kakhulu, sincoma ukusebenzisa i-rolls static cast kunye ne-groove ukufezekisa ukuhla kobunzima obuphantsi phakathi komphezulu womzimba kunye nomzantsi we-groove.

Inkcazo:

Inkqubo yokuvelisa :

Abalinganiswa:

1. Inkqubo: Forged + Machining + Heat Treatment

2. Unyango lobushushu: Iqhelekile / iAnealed / Cinyiwe / inomsindo

3. Imeko yonikezelo: I-Forged eshushu +Oomatshini abarhabaxa

4. Izixhobo zokuHlola: Uhlalutyo lwe-Metallurgical, i-Tensile tester tester, i-Hardness tester, i-Altimeter, i-Scale Micrometer, i-presser tester, njl.

5. Izinto eziphathekayo: intsimbi yekhabhoni, intsimbi engaxutywanga okanye intsimbi yealloyi

I-Slabs yimathiriyeli yokutya ye-hot strip mill okanye i-plate mill kunye neeblooms ziqengqeleka kwiibhilithi kwi-billet mill okanye amacandelo amakhulu kwi-structural mill. Imveliso evela kwi-strip mill iyabhijelwa kwaye, emva koko, isetyenziswe njengesondlo selitye lokusila elibandayo okanye isetyenziswe ngokuthe ngqo ngabavelisi. Iibhilithi, zokuphinda ziqengqeleke, emva koko ziqengqeleke zibe ngumrhwebi, ibha okanye i-rod mill. Umrhwebi okanye iibhari zokusila zivelisa iintlobo ngeentlobo zeemveliso ezimile njengeengile, iitshaneli, imiqadi, imijikelo (emide okanye ebhijelweyo) kunye neehexagons.

Isicelo:

Imiqulu yentsimbi engqukuva yegraphite pearlitic isetyenziswa kakhulu kwiindawo ezirhabaxa kunye neendawo eziphakathi zoomatshini bokungqusha. Umatshini wokuSebenzisa isinyithi, umatshini wokusika isinyithi, oomatshini boluleko besinyithi, oomatshini bokuphotha bentsimbi, aMalungu oomatshini bokuLungisa isinyithi, oomatshini bokubumba isinyithi, oomatshini bokuphosa isinyithi, njl.

Inkcazo:

Abalinganiswa:

1) Izinto eziphathekayo: i-Alloy Steel, i-Alloy Iron, i-Ductile Iron ethi 9Cr3Mo, 70NiMoV njl.

2) Umgangatho: GB, AISI, SAE, ASTM / ASME, EU, AS / NZS njl

3) Ubungakanani: ngokwezifiso njengemiyalelo

4) Ubunzima: ngokusekelwe kwiimfuno zomthengi

5) Ukubunjwa kweMichiza kunye nepropati yomatshini: njengoko kuchaziwe.

Isiqinisekiso: ISO 9001: 2008, iSatifikethi se-PED, i-TUV Rheinland, i-Bureau Veritas (BV), iRejista yeLloyd (LR), i-ABS, i-RINA Germanischer Lloyd (GL), iRejista yaseKorea yokuThumela (KR), iDet Norske Veritas (DNV), iNippon I-Kaiji Kyokai (NK) njl inokufumaneka ngokweemfuno zeprojekthi;

Inkampani yethu ekhethekileyo yentsimbi inokwenza imisebenzi eyahlukeneyo eyenziweyo eyenziwe ngoomatshini kunye nemveliso ukusuka kubungakanani obahlukeneyo kunye neenkqubo ngokomzobo ngamnye obonisiweyo okanye iimfuno. Nceda uzive ukhululekile ukwenza nayiphi na imibuzo ngokufanelekileyo.
