Ziziphi izinto ezifunekayo kwii-roller ze-Photovoltaic Welding Strip Rolling Mill

      I-rolling Mill ye-Photovoltaic Welding Strip Rolling Mill iyona nto ingundoqo yokusebenza, edibanisa ngokuthe ngqo kwaye icinezele ucingo lobhedu (izinto eziluhlaza). Idinga ukuhlangabezana neemfuno zamandla aphezulu, ukumelana nokunxiba okuphezulu, ukuzinza okuphezulu kwe-dimensional, kunye ne-surface smoothness ngexesha elifanayo ukuqinisekisa ubungakanani obuchanekileyo (ukunyamezela ukutyeba ngokuqhelekileyo ≤± 0.002mm) kunye nomgangatho ophezulu we-photovoltaic welding strip. Ukukhethwa kwezinto eziphathekayo kufuneka kujikeleze ezi mfuno ziphambili zilandelayo:

1,Iimfuno zemathiriyeli eziphambili (ubungakanani bokusebenza)

      Ubunzima obuphezulu kakhulu kunye nokumelana nokunxiba kwelitye lokusila kufuna ixesha elide lokukhupha ucingo lobhedu (ukuqina kobhedu malunga ne-HB30-50), kwaye umphezulu ulungele ukunxiba ngenxa yokukhuhlana kunye nokukhupha. Ukuba ukuqina akwanelanga, kuya kubangela ukuba indawo yokusila ibe yi-concave kwaye ukuchaneka kwe-dimensional kuyancipha, kuchaphazela ngokuthe ngqo ukufana kobunzima be-welding strip. Ngoko ke, i-roller material kufuneka ibe nobunzima bomphezulu we-≥ HRC60 (ubunzima be-Rockwell), kwaye i-substrate kufuneka ibe nenkxaso eyaneleyo yokuqina ukuze ugweme ukuphuka okunzima kunye nokuphuka.

      Uzinzo olugqwesileyo lwe-dimensional (i-coefficient ephantsi yokwandisa i-thermal): Ngethuba lenkqubo yokuguqa, ukushisa kwendawo kuveliswa yi-friction phakathi kwe-rolling mill kunye nezinto zobhedu. Ukuba i-coefficient yokwandiswa kwe-thermal ye-thermal iphezulu kakhulu, iya kubangela ukuba ubungakanani belitye lokusila buguquguquke kunye nobushushu, okukhokelela ekuphambukeni kubukhulu be-weld strip. Ngoko ke, izinto eziphathekayo kufuneka zibe ne-coefficient ephantsi yokwandisa i-thermal (ngokuqhelekileyo ifunwa ukuba ibe ngu-≤ 12 × 10 ⁻⁶/℃, kuluhlu lwe-20-100 ℃) ukuqinisekisa ukuzinza kwe-dimensional ngexesha lokuhamba kwexesha elide.

      Umgangatho ophezulu kakhulu wokuguda kunye nokuguda kwemicu ye-photovoltaic welding kufuna iimfuno ezingqongqo zomgangatho womphezulu (akukho mikrwelo, i-indentation, okanye amabala e-oxidation avumelekileyo), kunye nokuguda komphezulu welitye lokusila limisela ngokuthe ngqo ubume bomphezulu we-welding strip. Ngoko ke, izinto eziphathekayo ze-rolling mill kufuneka zibe lula ukupholisa kwinqanaba lesibuko elibushelelezi (Ra ≤ 0.02 μ m), kwaye akufanele kubekho iziphene ezifana neepores okanye ukufakwa ngaphakathi kwezinto ezithintekayo ukuphepha iziphene zomhlaba emva kokupholisa.

      Ngethuba lokusebenza kwe-rolling mill kunye nokudinwa okulungileyo kunye nokuchasana kwempembelelo, i-rolling mill idinga ukujamelana nemithwalo eguquguqukayo ye-cyclic (i-compression, i-friction), enokuthi iholele ngokulula kwiintanda zokudinwa ukuba isetyenziswe ixesha elide; Ngeli xesha, ukuguquguquka kwisantya sokubeka ucingo kunokubangela imithwalo yempembelelo ekhawulezileyo. Ngoko ke, izinto eziphathekayo kufuneka zibe namandla okudinwa okuphezulu (ukugoba amandla okukhathala ≥ 800MPa) kunye neqondo elithile lokuqina ukuphepha ukuqhekeka okanye ukuphulwa komphetho we-rolling mill phantsi komthwalo wexesha elide.

      I-Corrosion kunye nokumelana ne-oxidation: Indawo eqengqelekayo inokudityaniswa nomphunga wamanzi kwaye ilandele amabala e-oyile emoyeni, kwaye umcu wokuwelda olandelayo kufuneka ucocwe phambi kokufakwa kwe-tin. Ukuba izinto ze-roller zixhomekeke kwi-oxidation okanye i-corrosion, iya kubangela ukubunjwa kwe-oxide layer phezu komhlaba, ingcolise ubuso bomgca we-welding. Ngoko ke, izinto eziphathekayo zifuna ukuchasana kakuhle kwi-corrosion ye-atmospheric kwiqondo lokushisa elingaphakathi kunye nokungcoliswa kwe-oyile encinci, ukuphepha i-oxidation yomhlaba kunye ne-peeling.

2Iimfuno ezincedisayo (ukulungiswa nokulungiswa kwemilinganiselo)

      Ukucutshungulwa: Izinto eziphathekayo kufuneka zibe lula ukwenza ukugaya ngokuchanekileyo (ukuqinisekisa ukuba ukunyamezela ukujikeleza kwendawo ye-roller ≤ 0.001mm) kunye nokupholisa, ukuphepha ukunyuka kweendleko ngenxa yobunzima bokucubungula okuphezulu;

      I-Thermal conductivity: Ezinye ii-speed-speed rolling Mills zifuna iinkqubo zokupholisa kunye nezixhobo ezithile ze-thermal conductivity (ezifana ne-hard alloy conductivity thermal conductivity ≥ 80W / (m · K)) ukuququzelela ukuchithwa kwexesha lobushushu obudibeneyo kunye nokuqinisekisa ngakumbi ukuzinza kwe-dimensional.
