Yiziphi izidingo ezibonakalayo zama-roller we-Photovoltaic Welding Strip Rolling Mill

      Umshini wokugaywa we-Photovoltaic Welding Strip Rolling Mill uyingxenye ewumgogodla yokusebenza, ethintana ngokuqondile futhi incinde ucingo lwethusi (impahla eluhlaza). Idinga ukuhlangabezana nezidingo zamandla aphezulu, ukumelana nokugqoka okuphezulu, ukuzinza kwe-dimensional ephezulu, kanye nokushelela kwendawo ngesikhathi esifanayo ukuze kuqinisekiswe ubukhulu obunembile (ukubekezelelana kokuqina ngokuvamile ≤± 0.002mm) kanye nekhwalithi yangaphezulu ye-photovoltaic welding strip. Ukukhethwa kwezinto ezibonakalayo kufanele kuhambisane nezidingo ezibalulekile ezilandelayo:

1,Izidingo zezinto ezibalulekile (ubukhulu bokusebenza)

      Ubulukhuni obuphezulu kakhulu nokumelana nokugqokwa kwesigayo esiginqikayo kudinga ukukhishwa kwentambo yethusi isikhathi eside (ukuqina kwethusi kumayelana ne-HB30-50), futhi indawo engaphezulu ijwayele ukuguga ngenxa yokungqubuzana nokukhishwa. Uma ubulukhuni bunganele, kuzokwenza ukuthi indawo yokugaya igoqeke futhi kunciphe ukunemba kobukhulu, kuthinte ngqo ukufana komugqa wokushisela. Ngakho-ke, okokusebenza kwerola kudinga ukuba nokuqina kwendawo okungu-≥ HRC60 (ukuqina kwe-Rockwell), futhi i-substrate idinga ukwesekwa kokuqina okwanele ukugwema ukuphuka okuqinile nokuphukayo.

      Ukuzinza kwe-dimensional okuhle kakhulu (i-coefficient ephansi yokwandisa okushisayo): Phakathi nenqubo yokugingqa, ukushisa kwendawo kukhiqizwa ukungqubuzana phakathi komshini wokugaya nezinto zethusi. Uma i-coefficient ye-thermal expansion coefficient iphezulu kakhulu, izobangela usayizi wokugaya ukuthi uguquguquke nezinga lokushisa, okuholela ekuphambukeni kogqinsi lomugqa wokushisela. Ngakho-ke, okokusebenza kudinga ukuba ne-coefficient ephansi yomugqa wokunweba okushisayo (ngokuvamile okudingekayo ukuze kube ≤ 12 × 10 ⁻⁶/℃, ebangeni lika-20-100 ℃) ukuze kuqinisekiswe ukuzinza kobukhulu ngesikhathi sokugingqika kwesikhathi eside.

      Ubushelelezi obuphezulu kakhulu kanye nokucaba kwemichilo yokushisela ye-photovoltaic kudinga izimfuneko eziqinile zekhwalithi yendawo (akukho kuklwebheka, ama-indentation, noma amachashaza e-oxidation), futhi ubushelelezi bendawo yesigayo esiginqikayo bunquma ngokuqondile isimo esingaphezulu somugqa wokushisela. Ngakho-ke, izinto zokugaya kufanele kube lula ukupholishela ezingeni lesibuko elibushelelezi (Ra ≤ 0.02 μ m), futhi akumele kube namaphutha njengama-pores noma ukufakwa ngaphakathi kwempahla ukuze kugwenywe ukukhubazeka okungaphezulu ngemuva kokupholisha.

      Ngesikhathi sokusebenza kwesigayo esinokukhathala okuhle kanye nokumelana nomthelela, umshini wokugaya udinga ukumelana nemithwalo eguquguqukayo yama-cyclic (ukucindezela, ukungqubuzana), okungaholela kalula ekuqhekekeni kokukhathala uma kusetshenziswe isikhathi eside; Ngaleso sikhathi, ukushintshashintsha kwesivinini sokubeka izintambo kungase kubangele imithwalo esheshayo. Ngakho-ke, okokusebenza kudinga ukuba nakho kokubili amandla aphezulu okukhathala (amandla okukhathala okugoba ≥ 800MPa) kanye nezinga elithile lokuqina ukuze kugwenywe ukuqhekeka noma ukuphuka komphetho wesigayo esiginqikayo ngaphansi komthwalo wesikhathi eside.

      Ukumelana nokugqwala kanye ne-oxidation: Indawo egingqikayo ingase ihlangane nomhwamuko wamanzi futhi ilandele amabala kawoyela emoyeni, futhi umucu wokushisela olandelayo udinga ukuhlanzwa ngaphambi kokufakwa kukathayela. Uma izinto ze-roller zijwayele uku-oxidation noma ukugqwala, kuzodala ukwakheka kwengqimba ye-oxide ebusweni, kungcolise ubuso bomugqa wokushisela. Ngakho-ke, impahla idinga ukumelana kahle nokugqwala komkhathi ekamelweni lokushisa kanye nokugqwala okuncane kokungcoliswa kwamafutha, ukugwema ukugqwala kwe-oxidation nokuxebuka.

2,Izidingo ezisizayo (ubukhulu bokucubungula nokulungiswa)

      I-Machinability: Impahla kufanele ibe lula ukwenza ukugaya okunembayo (ukuqinisekisa ukuthi ukubekezelela okuyindilinga kwendawo ye-roller ≤ 0.001mm) nokupholisha, ukugwema ukukhuphuka kwezindleko ngenxa yobunzima bokucubungula okuphezulu;

      I-Thermal conductivity: Ezinye izigayo eziginqikayo ezinesivinini esikhulu zidinga amasistimu okupholisa nezinto ezithinta ukushisa okuthile (okufana ne-hard alloy thermal conductivity ≥ 80W/(m · K)) ukuze kube lula ukushabalaliswa okufika ngesikhathi kokushisa okungqubuzanayo nokuqinisekisa ukuqhubeka kokuqina kwe-dimensional.
