Menene buƙatun kayan aiki don rollers na Photovoltaic Welding Strip Rolling Mill

      Mirgine niƙa na Photovoltaic Welding Strip Rolling Mill shine ainihin sashin aiki, wanda ke tuntuɓar kai tsaye kuma yana matse wayar tagulla (raw material). Yana buƙatar saduwa da buƙatun ƙarfin ƙarfin ƙarfi, juriya mai ƙarfi, kwanciyar hankali mai girma, da santsi na ƙasa a lokaci guda don tabbatar da madaidaicin girman (haƙuri na kauri yawanci ≤ ± 0.002mm) da ingancin farfajiya na tsiri waldi na hotovoltaic. Zaɓin kayan ya kamata ya haɗa da mahimman buƙatun masu zuwa:

1,Abubuwan buƙatun kayan mahimmanci (girman aiki)

      Maɗaukakin ƙarfi da juriya na injin niƙa na buƙatar dogon lokaci extrusion na jan karfe waya (taurin jan karfe kusan HB30-50), kuma saman yana da saurin lalacewa saboda gogayya da extrusion. Idan taurin bai wadatar ba, zai sa shimfidar niƙa ta zama maɗaukaki kuma daidaiton girman ya ragu, kai tsaye yana shafar daidaiton kauri na walda. Don haka, abin nadi yana buƙatar samun taurin saman ≥ HRC60 (Taurin Rockwell), kuma maƙasudin yana buƙatar samun isasshen tallafi don gujewa karaya mai ƙarfi da karye.

      Kyakkyawan kwanciyar hankali mai girma (ƙananan haɓakar haɓakar zafin zafi): Yayin aikin mirgina, zafi na gida yana haifar da gogayya tsakanin injin mirgine da kayan jan ƙarfe. Idan madaidaicin faɗaɗawar thermal na kayan ya yi girma sosai, zai sa girman niƙa ya canza tare da zafin jiki, yana haifar da karkatacciyar kauri na tsiri na walda. Sabili da haka, kayan yana buƙatar samun ƙarancin haɓaka haɓaka haɓakar haɓakar thermal mai ƙarancin layi (yawanci ana buƙatar zama ≤ 12 × 10 ⁻⁶ / ℃, a cikin kewayon 20-100 ℃) don tabbatar da kwanciyar hankali a lokacin juyawa na dogon lokaci.

      Santsi mai tsayi mai tsayi da kwanciyar hankali na raƙuman walda na hotovoltaic yana buƙatar ƙaƙƙarfan buƙatun ingancin ƙasa (ba a ba da izinin tabo, indentations, ko oxidation spots ba), kuma santsin saman injin mirgina kai tsaye yana ƙayyade yanayin shimfidar walda. Sabili da haka, kayan injin mirgina yakamata su kasance da sauƙin gogewa zuwa santsi matakin madubi (Ra ≤ 0.02 μ m), kuma kada a sami lahani kamar pores ko haɗawa cikin kayan don guje wa lahani na sama bayan gogewa.

      A lokacin aikin injin mirgina tare da gajiya mai kyau da juriya mai tasiri, injin mirgina yana buƙatar jure wa nau'ikan nau'ikan nau'ikan cyclic (matsi, jujjuyawar), wanda zai iya haifar da faɗuwar gajiya idan an yi amfani da shi na dogon lokaci; A halin yanzu, jujjuyawar saurin shimfiɗa waya na iya haifar da tasirin tasiri nan take. Sabili da haka, kayan yana buƙatar samun duka ƙarfin gajiya mai ƙarfi (ƙarfin gajiyar lankwasawa ≥ 800MPa) da wani ƙayyadaddun ƙaƙƙarfan ƙarfi don guje wa fashewa ko ɓarnawar injin mirgina ƙarƙashin kaya na dogon lokaci.

      Lalata da juriya na iskar oxygen: Yanayin da ake birgima na iya haɗuwa da tururin ruwa da tabon mai a cikin iska, kuma ana buƙatar tsabtace tsiri na walda na gaba kafin a saka kwano. Idan abin nadi yana da saurin kamuwa da iskar shaka ko lalata, zai haifar da samuwar wani Layer na oxide a saman, yana gurɓata saman tsiri na walda. Sabili da haka, kayan yana buƙatar samun juriya mai kyau ga lalata yanayi a dakin da zafin jiki da ƙananan gurbataccen gurbataccen mai, don kauce wa oxidation surface da peeling.

2,Bukatun taimako (girman sarrafawa da kulawa)

      Machinability: Kayan ya kamata ya zama mai sauƙi don aiwatar da niƙa daidai (tabbatar da juzu'in juzu'in abin nadi shine ≤ 0.001mm) da gogewa, guje wa haɓakar farashin saboda wahalar aiki mai girma;

      Thermal conductivity: Some high-speed rolling mills require cooling systems and materials with certain thermal conductivity (such as hard alloy thermal conductivity ≥ 80W/(m · K)) to facilitate timely dissipation of frictional heat and further ensure dimensional stability.
