Ninaamini kuwa mpya sahani ya alumini makampuni ya biashara hawajui mengi kuhusu kasoro za kawaida za sahani za alumini. Ruhusu Alumini ya Xinyitong ikutambulishe kwa ufupi kasoro kadhaa za kawaida za sahani za alumini, ili kutosababisha shida isiyo ya lazima kwa biashara kwa sababu ya uzembe wao wenyewe!
1. Umbo la sahani:
(1) Safu iliyoyumba: harakati zisizo za kawaida zilizoyumba kati ya safu ya uso wa mwisho na safu ya ukanda, resulting in uneven end surface. Causes: billet isiyo sawa; udhibiti usiofaa wa uncoiling wa kinu na mvutano wa kujiviringisha; marekebisho yasiyofaa ya rolls flattening, na kadhalika.
(2) Roli iliyokunjwa: The roll core is seriously deformed and the roll shape is not round. Cause: Mvutano usiofaa wakati wa mchakato wa crimping; ukandamizaji wa nguvu za nje.
(3) Kuinama kwa upande: It is manifested as the bending of the plate shape to one side. Cause: Shinikizo la leveler haitoshi.
(4) Wimbi: A general term for various uneven phenomena formed by uneven deformation of aluminum plates and aluminum strips. The waves generated by the plate and the edge are called edge waves, mawimbi yanayozalishwa katikati yanaitwa mawimbi ya kati, na mawimbi kati ya kati na ubavu sio katikati wala pande zote mbili huitwa mawimbi ya mbavu mbili., which are smaller in size and usually Waves that are circular are called break waves. Causes: Marekebisho ya pengo la roll isiyo na usawa, udhibiti usio na maana wa sura ya roll; lubrication na baridi isiyo na usawa, deformation isiyo sawa ya sahani ya alumini; usambazaji usio na maana wa kupunguzwa kwa pasi, na kadhalika.
2. Vipimo:
(1) Uvumilivu wa unene: Uvumilivu unaoruhusiwa hapa chini 1.0 ± 1%, juu 1.0 ± 5%, moja nje ya uvumilivu * 2 nyakati;
(2) Uvumilivu wa upana: ±0.1MM chini ya 3.2MM, ±0.2MM juu ya 3.2MM;
(3) Uvumilivu wa urefu: +5-3MM. The reason for the thickness tolerance, tatizo la kupima unene; sababu ya uvumilivu wa upana, marekebisho yasiyofaa ya shear disc; sababu ya uvumilivu wa urefu, marekebisho ya mashine ya kunyoa ni tatizo.
3. Uso:
(1) Kuchora: Tofauti ya rangi isiyo ya kawaida kwenye uso wa roll huchapishwa mara kwa mara kwenye uso wa kamba wakati wa mchakato wa kusongesha kwa sababu ya kasoro na ukanda uliovunjika wa kamba..
(2) Mikwaruzo: the appearance of scars distributed in bundles on the surface of the aluminum plate. Cause: kutengana kwa mitambo au bandia kati ya tabaka za sahani ya alumini.
(3) Kupiga makali: Baada ya kukunja au kukata manyoya, makali ya strip ni warped.
(4) Kutu: It is manifested as point-like or flaky white spots or black spots on the surface of the aluminum plate. Cause: Asidi, alkali au maji yaliyoingia wakati wa uzalishaji, ufungaji, usafirishaji na uhifadhi.
(5) Doa ya mafuta juu ya uso: it is manifested as dirt on the surface. Cause: Mafuta ya kupoeza ni chafu na hewa inayovuma haina nguvu.
(6) Mikwaruzo: There are line-distributed scars on the surface of the aluminum plate. Causes: Sahani ya mwongozo inachomoza au kung'ang'ania alumini inapoviringishwa kuwa tambarare; mikwaruzo hutokea wakati wa kukata nywele; ukaguzi usiofaa wa mwongozo na kuinua.
(7) Kuinama kwa upande: the longitudinal sides of the plate and belt are in a non-straight state that is bent to one side. Causes: Kiasi cha kupunguzwa kwa ncha zote mbili za kinu cha kusongesha ni tofauti;
(8) Matangazo nyeusi juu ya uso: There are needle-shaped black spots on the surface of the aluminum plate. Cause: Kioevu cha tanuru sio safi.
4. Mali ya mitambo:
(1) The hardness is not enough. Sababu, nyenzo/utunzi, mchakato wa matibabu ya joto.
(2) Kupiga chapa na kupasuka, hard or soft. Material or condition issues.
(3) Kasoro zingine: mawimbi ya maji baada ya oxidation, mistari nyeusi na nyeupe; maua ya giza juu ya uso; si mkali juu ya uso, na kadhalika.
