Yiziphi izidingo ezibonakalayo zama-roller of the photovoltaic welding strip rolling mill

      Isigayo esigoqisayo se-Photovoltaic Welding strip Rolling Mill e-Core Working Content, okuthintwa ngqo futhi sinciphise ucingo lwethusi (impahla eluhlaza). Idinga ukufeza izidingo zamandla aphezulu, ukumelana okuphezulu, ukuqina okuphezulu, kanye nokuqina komhlaba ngasikhathi sinye ukuqinisekisa usayizi oqondile (ukubekezelelana okukhulu kuvame ukucaciswa kwe-Photovoltaic welding strip. Ukukhethwa kwezinto ezibonakalayo kufanele kuzungeze izidingo eziyinhloko ezilandelayo:

1,Izidingo Zokwenziwa Okuyisisekelo (ubukhulu bokusebenza)

      Ubulukhuni obuphezulu kakhulu nokuvinjwa kokugqoka kwegayidi lokugoqa kudinga ukukhishwa isikhathi eside kocingo lwethusi (ubulukhuni bethusi bumayelana ne-HB30-50), futhi ingaphezulu lithambekele ekugqokeni ngenxa yokungqubuzana nokukhishwa. Uma ubulukhuni alwanele, kuzodala ukuthi indawo yokugaya egayiwe ibe yi-concave kanye nokunemba okunobukhulu ukwehla, okuthinta ngokuqondile ukufana kokuqina kwe-welding strip. Ngakho-ke, impahla ye-roller idinga ukuba nobulukhuni obungaphezulu kwe-≥ HRC60 (Rocwell Hurdness), futhi i-substrate idinga ukuba nokwesekwa ngokwanele ukusekelwa kokugwema ukugwema kanzima nokuhlunga.

      Ukuqina okuhle kobukhulu (ukunwebeka okuphansi okuphezulu kwe-cansension): Ngesikhathi senqubo yokugoqa, ukushisa kwasendaweni kukhiqizwa ukungqubuzana phakathi kokugaya okugoqisayo kanye nezinto zethusi. Uma i-coeffition ye-thermal yokunwebeka ye-thermal iphezulu kakhulu, kuzodala ukuthi i-rolling mill uguqule ngokushisa, okuholela ekuphambukeni ngobukhulu bemicu ye-weld. Ngakho-ke, izinto ezibonakalayo zidinga ukuba ne-coefficion ebanzi etholwayo eqondile (imvamisa edingekayo ukuze ibe ≤ 12 × 10 × / ℃, ebangeni lama-20-100 ℃) ukuqinisekisa ukuqina okubucayi ngesikhathi sokugoqa isikhathi eside.

      Ubungcweti obukhulu kakhulu kanye nokufutheka kwama-Photovoltaic welding strips kudinga izidingo zekhwalithi ephezulu (akukho ukuklwebheka, ukuvezwa, noma izindawo ezibushelelezi ze-rolling zinquma ngqo isimo somugqa we-welding. Ngakho-ke, okubonakalayo kwesigayo sokugoqa kufanele kube lula ukuklezela ukuPhesha kwesibuko okubushelelezi (RA ≤ 0.02 μ), futhi akufanele kube namaphutha anjenge-pores noma ukufakwa ngaphakathi kwezinto ezibonakalayo ukugwema iziphepho zangaphezulu.

      Ngesikhathi sokusebenza kwesigayo esidilikayo ngokukhathala okuhle nokumelana nomthelela, i-rolling mic idinga ukubekezelela imithwalo eguquguqukayo ye-cyclic (ukucindezelwa, ukungezwani), okungaholela kalula ekuqhekekeni kokukhathala uma kusetshenziselwa isikhathi eside; Okwamanje, ukuguquguquka kwejubane lokubeka ucingo kungahle kuholele emithanjeni yomthelela wesikhathinisikhathi ngaso leso sikhathi. Ngakho-ke, lokho okubonakalayo kudinga ukuba namandla okukhathala okuphezulu (ukubopha ukukhathala kwaqinisi

      Ukuphikiswa kokugqwala kanye nokuphikiswa kwe-oxidation: Imvelo yokugoqa ingahle ithintwa nge-vapor yamanzi futhi ilandele amabala kawoyela emoyeni, futhi umucu olandelayo we-welding udinga ukuhlanzwa ngaphambi kokufakwa kwe-tin plating. Uma impahla ye-roller ithambekele ku-oxidation noma ukugqwala, kuzodala ukwakheka kwesendlalelo se-oxide ebusweni, kungcolise ubuso be-welding. Ngakho-ke, lokho okubonakalayo kudinga ukumelana nokuphikisana okuhle kokonakala komkhathi ekushiseni kwamakamelo nokugqwala okuncane kokungcola kawoyela, ukugwema ukuxhumeka kwe-oxidation kanye nokukhonkotha.

2,Izidingo Ezisizayo (ukucubungula kanye nobukhulu bokulungisa)

      Imishini: Izinto ezibonakalayo kufanele kube lula ukwenza ukugaya okunembile (ukuqinisekisa ukuthi ukubekezelela ukuzungeza kwe-roller komhlaba kungukuthi 0.001mm) nokuphoqelela, ukugwema izindleko zandayo ngenxa yobunzima obuphezulu;

      Ukuvuselelwa okushisayo: Amanye ama-rolling ama-rolling adinga amasistimu apholile nezinto zokwakha ezinobuhlakani obuthile obushisayo (njenge-hard alloy thermal activation ≥ 80w / (m · k)
