Chitoliro chachikulu chopanda msokomatenthedwe akamaumba njira kupanga

Matenthedwe kupanga kupanga ndondomeko, kuphatikizapo lalikulu-m'mimba mwake mopanda msoko otentha adagulung'undisa ndi otentha extrusion wa njira ziwiri, woyamba zimagwiritsa ntchito kupanga olowa gulu chitoliro, amene amagwira ntchito mopanda gulu chitoliro kupanga chitoliro.

Kugudubuza ndi njira yachikhalidwe yokonzekera chitoliro chachitsulo chopanda m'mimba mwake.Hot anagubuduza mu zinthu kuwotcherera kuthamanga, ngati mapindikidwe ndi lalikulu mokwanira, kuthamanga anapereka mpukutu wa zitsulo kuwononga pamwamba pa okusayidi filimu, ndi atomiki pamwamba kukhudzana, kuti pamalo awiri ndi welded pamodzi.Zoyipa za rolling ndi:

Ubwino wogubuduza: zokolola zambiri, zabwino, zotsika mtengo, ndipo zimatha kupulumutsa kuwonongeka kwazinthu zachitsulo, chifukwa chake ndikugwiritsa ntchito kwambiri ukadaulo wopanga zinthu zambiri.Kugudubuza gulu pepala kaphatikizidwe 90% ya okwana gulu gulu, ndipo nthawi zambiri ntchito pa chitoliro khoma makulidwe zosakwana 32mm wa processing.

Zoyipa za kugubuduza: ndalama zanthawi imodzi, komanso kuphatikiza kwazinthu zambiri sikungatheke ndi kugubuduza zovuta.Panopa ndi luso ambiri ankagwiritsa ntchito anagubuduza zitsulo, zosapanga dzimbiri gulu chitoliro olowa kupanga.

Hot extrusion nthawi zambiri imachitika pa chubu cha bi-zitsulo, chotchedwa composite extrusion (coextrude).Coextrusion pakali pano ndiyo njira yabwino kwambiri yopangira chitsulo chosapanga dzimbiri komanso chitoliro chapamwamba cha faifi tambala wopanda msokonezo, Japan Chitsulo chopangidwa ndi njira iyi 8in (203.2mm) pansi pa chitoliro cha bimetallic composite.Ndi chiphaso chachikulu cham'mimba mwake chokhala ndi zitsulo ziwiri kapena zingapo zopanda kanthu zomwe zimatenthedwa mpaka pafupifupi 1200.℃, ndiyeno extruded kudzera annular danga lopangidwa ndi nkhungu ndi mandrel.Pamene extrusion billet mtanda gawo yafupika 10: 1, mkulu extrusion kuthamanga ndi kutentha pa mawonekedwe opangidwa "anzanu kuwotcherera" kuwotcherera kwenikweni, kulimbikitsa mofulumira ndi ponse kufalikira kwa mawonekedwe pakati osakaniza kukwaniritsa zitsulo zomangira mawonekedwe.Pamaso extrusion gulu chubu kupanga njira, pali atatu: ndi forging billet kuboola ndi kukulitsa ndi extrusion otentha analandira;kuponya molunjika kwa centrifugal;tinthu tating'ono ting'onoting'ono ta ufa.Pali zida ziwiri zazitsulo zomwe zimagwiritsidwa ntchito mkati ndi kunja kwa ufa, wotchedwa "NUVAL" teknoloji, imatha kupanga ma alloys atsopano, koma mtengo wake ndi wokwera kwambiri pokonzekera ufa.Zoyipa za Coextrusion ndi:

Ubwino otentha extrusion : The mawonekedwe ndi metallurgically womangidwa;mphamvu nawo ndondomeko extrusion ndi nkhawa kwathunthu, makamaka bwino yogwirizana ndi otentha workability, mkulu aloyi processing otsika plasticity zitsulo.

Kuipa kwa extrusion otentha: Monga anatsimikiza ndi extrusion ndondomeko pamodzi ndi lalifupi kwambiri mayamwidwe mawonekedwe zinthu, kawirikawiri chifukwa cha kukhalapo kwa okusayidi mafilimu akhudzidwa, mpaka pano okha ndi gulu extrusion gulu mpweya zitsulo, zitsulo zosapanga dzimbiri ndi mkulu faifi tambala aloyi pakati. .Iwo ananena kuti yaing'ono mapindikidwe kukana wa extrusion otentha, kulola mlingo waukulu wa mapindikidwe aliyense, chifukwa apamwamba pamwamba roughness, choncho kukhalanso ozizira akugubuduza extrusion otentha (kapena kujambula) njira kupanga chitoliro gulu. .
