Babban diamita bututu maras sumulthermal gyare-gyaren masana'antu tsari

Thermal kafa masana'antu tsari, ciki har da manyan-diamita sumul zafi-birgima da zafi extrusion na biyu hanyoyin, tsohon da aka yafi amfani a samar da composite bututu gidajen abinci, wanda ya shafi m hada bututu samar.

Rolling wata hanya ce ta gargajiya ta shirya manyan bututun ƙarfe maras diamita.Zafafan mirginawa a cikin abu matsa lamba na walda, idan nakasar ta yi girma sosai, matsawar da nadin karfen ke yi zai lalata saman fim din oxide, fuskar atomic da ke haduwa, ta yadda bangarorin biyu suka hade waje guda.Abubuwan rashin amfani sune:

Abũbuwan amfãni daga mirgina: high yawan aiki, mai kyau quality, low cost, kuma zai iya cece mai yawa lalacewa da tsagewar karfe kayan, sabili da haka ne musamman m aikace-aikace na composite abu samar da fasaha.Rolling composite sheet hada 90% na jimlar hada farantin, kuma sau da yawa ana amfani da bututu bango kauri na kasa da 32mm na aiki.

Rashin hasara na mirgina: zuba jari na lokaci ɗaya, amma kuma yawancin haɗuwa da kayan abu ba za a iya samu ta hanyar mirgina hadaddun ba.A halin yanzu fasahar da aka fi amfani da ita don yin amfani da ƙarfe mai mirgina, masana'anta na bututun ƙarfe mai haɗaɗɗun bututun ƙarfe.

Ana aiwatar da extrusion mai zafi gabaɗaya don bututun ƙarfe guda biyu, wanda ake kira extrusion composite (coextrude).Coextrusion a halin yanzu shine hanya mafi kyau don samar da bakin karfe da kuma babban nickel gami da bututun da ba su da kyau, Japan Karfe da aka samar ta wannan hanyar 8in (203.2mm) a ƙasan bututun kumshin bimetallic.Yana da wani babban diamita hadaddun kunshi biyu ko fiye karfe blank ana mai tsanani zuwa game da 1200℃, sa'an nan kuma extruded ta cikin annular sarari kafa ta mold da kuma mandrel.Lokacin da extrusion billet giciye-section aka rage zuwa 10: 1, high extrusion matsa lamba da kuma zafin jiki a ke dubawa samar da "matsi waldi" waldi sakamako, inganta m da tartsatsi watsawa na dubawa tsakanin hade don cimma metallurgical bonding dubawa.Kafin extrusion hada tube masana'antu hanya, akwai uku: da ƙirƙira billet sokin da kuma kara girma da zafi extrusion samu;kai tsaye centrifugal juya simintin gyaran kafa;lalata resistant foda barbashi.Akwai nau'ikan albarkatun ƙarfe guda biyu da ake amfani da su a ciki da waje da foda, da ake kira fasahar "NUVAL", na iya haɓaka sabbin gami, amma farashin ya yi yawa don shirya foda.Lalacewar coextrusion sune:

Abũbuwan amfãni daga zafi extrusion : The dubawa ne metallurgically bonded;sojojin da hannu a cikin extrusion tsari ne gaba daya danniya, shi ne musamman da dace da zafi workability, high gami aiki low plasticity na karafa.

Rashin hasara na zafi extrusion: Kamar yadda ƙaddara ta hanyar extrusion tsari hade tare da wani ɗan gajeren watsawa dubawa abubuwa, yawanci saboda kasancewar oxide fina-finai da aka shafi, ya zuwa yanzu iyakance ga hadaddun extrusion hada carbon karfe, bakin karfe da kuma high nickel gami tsakanin. .An lura da cewa karamin nakasawa juriya na zafi extrusion, kyale babban mataki na nakasawa kowane, sakamakon hakan surface roughness, sabili da haka kuma zama kara sanyi mirgina zafi extrusion (ko zane) na Hanyar Manufacturing wani hadadden bututu. .
