Duralumin yog cov khoom siv ntau yam ua los ntawm txhuas, magnesium, zinc thiab manganese. Lwm cov khoom ntxiv tau ntxiv rau qhov sib tov thaum lub sijhawm tsim khoom.

Ntau yam ntawm duralumin

Nyob ntawm qee yam kev ua haujlwm, cov hlau muaj nws qhov kev faib tawm.

Nws suav nrog cov hauv qab no hom duralumin:

• D1.
• D16.
• D17 thiab D19.
• D18.

Lawv sib txawv hauv kev sib xyaw thiab kev tsim khoom siv tshuab.

D1 - thawj hom duralumin. Nws lub npe tsis tau hloov txij li xyoo 1908. Cov muaj pes tsawg leeg kuj tseem zoo ib yam (txhuas, tooj liab, magnesium thiab manganese). Alloy D16 yog suav tias yog qhov ruaj khov thiab txawv ntawm qhov dhau los hauv feem pua ntawm magnesium. Dural qib D17 thiab D19 yog kub-resistant. D18 yog ib qho alloy nrog cov ntsiab lus tsawg ntawm magnesium thiab tooj liab. Nws yog yas.

Note. Ntxiv nrog rau cov khoom tseem ceeb, silicon thiab hlau tau ntxiv rau qhov muaj pes tsawg leeg ntawm duralumin.

Scope of application

Duralumin yog ib pawg ntawm cov hlau tseem ceeb, uas ua lub luag haujlwm txiav txim siab hauv kev tsim kho ntawm txhua yam khoom. Niaj hnub no cov hlauyog siv tau zoo hauv kev tsim cov nkoj, kev tsim cov kav dej rau ntau lub hom phiaj, kev tsim cov tsheb ciav hlau ceev thiab ntau ntxiv. Qhov no yog vim qhov zoo ntawm cov khoom, nrog rau nws cov yam ntxwv zoo heev.

Txhuas, tus nqi ntawm qhov sib txawv ntawm 50-75 rubles ib kg, tau ntev tau siv nyob rau hauv tag nrho cov sectors ntawm kev tsim kho. Nws tsis yog tsuas yog yas, tab sis kuj yog hlau ruaj. Nws yog vim li no uas nws tau los ua lub hauv paus rau kev tsim cov duralumin alloy.

Cov tsos ntawm cov hlau no nyiam cov neeg tsim qauv dav hlau. Nyob rau hauv lub xyoo pua 20th, lub dav hlau tau tshwm sim thawj zaug uas duralumin yog cov khoom siv tseem ceeb. Nws tau poob nws qhov kev tiv thaiv corrosion vim yog siv magnesium thiab silicon hauv nws cov khoom, tab sis tau dhau los ua muaj zog dua aluminium.

Cov khoom lag luam los ntawm cov hlau no

Duralumin yog lub zog muaj zog alloy los ntawm ntau yam khoom tsim. Lawv tuaj yeem siv rau hauv kev ua liaj ua teb (thaum npaj cov tsev neeg ntiag tug) thiab ntawm kev lag luam.

Cov ntaub ntawv hauv qab no yog tsim los ntawm duralumin:

• pipes;
• daim ntawv;
• plates;
• bars.

Duralumin yeeb nkab tuaj yeem ua profiled thiab puag ncig. Lawv txawv ntawm cov peev txheej thiab qee tus yam ntxwv.

Kev kos npe ntawm cov kav dej duralumin raws li cov txiaj ntsig ntawm kev ua tiav zaum kawg:

• "M" - cov ntaub ntawv yas thiab mos.
• "H" - cov kav dej uas txo qis zog.
• "T" -hardened hlau uas tau lawm ib txwm muaj hnub nyoog.
• "T1" - cov kav dej uas tau dhau los ua cov txheej txheem tawv tawv thiab kev laus laus.

Note. Feem ntau ntawm cov khoom yog tsim los ntawm D16 qib duralumin alloy.

Duralumin yeeb nkab tuaj yeem ua nyias-walled lossis tuab-walled. Ob hom yog siv tau zoo hauv kev tsim kho. Phab ntsa tuab ntawm cov yeeb nkab ntawm thawj hom yog 0.5-5 hli. Hla ntu - 6-150 mm. Thick-walled kav yog nthuav tawm nyob rau hauv ib tug loj assortment. Lawv txoj kab uas hla yog 30-300 hli, phab ntsa thickness yog 6-40 hli.

Duralumin profile kav kuj tuaj yeem muaj ntau hom. Khoom Parameters:

• length - 1-6 m;
• ntu - 10x10-60x60 mm;
• wall thickness - 1-5 mm.

Qhov tseem ceeb. Tag nrho cov ntaub ntawv ntawm hom no yog tsim raws li GOSTs.

Duralumin nplooj ntawv kuj tau nrov hauv kev tsim kho. Lawv thickness txawv ntawm 0.3 hli thiab 10 hli. Lawv tau siv dav hauv kev ua haujlwm sab nraum zoov. Nyob rau hauv kev thauj mus los, tshwj xeeb embossed duralumin nplooj ntawv yog siv, uas yog endowed nrog anti-slip zog. Koj tseem tuaj yeem siv cov hlau no hauv kev tsim cov davhlau ntawm cov ntaiv, phab ntsa panels, tsim cov partitions thiab ntau lwm cov qauv.

Duralumin daim hlau nyob rau hauv lawv cov tsos zoo li cov nplooj ntawv, tsuas yog nrog ib tug ntau dua thickness - 60 hli. Nrog rau qhov ntsuas no, qhov ntev ntawm cov khoom ncav cuag 500 mm. Lawv yog siv rau kev tsim kho ntawm ntau yam kev tsim kho thiab kev lag luam.

Duralumin pas nrig - khoom profile, seemuas tuaj yeem yog puag ncig, hexagonal thiab duab plaub. Nws lub ntsiab kom zoo dua yog practicality. Cov khoom yog yas heev thiab txiav zoo. Cov khoom yog lub teeb yuag.

Duralumin specifications

Hlau tau txais txiaj ntsig nrog cov ntsuas zoo heev. Qhov tseeb no tau ua lub luag haujlwm tseem ceeb hauv nws qhov chaw, nrog rau hauv nws daim ntawv thov hauv ntau qhov chaw ntawm tib neeg lub neej.

Duralumin yog cov hlau muaj zog. Nyob ntawm cov cim, nws muaj peev xwm tiv taus ntau yam khoom siv thiab lub cev. Cov hlau tsis tuaj yeem nqus dej noo. Txawm li cas los xij, cov khoom lag luam duralumin raug rau nws.

Note. Dural alloy tsis tau txais txiaj ntsig nrog cov khoom tiv thaiv corrosion. Vim li no, qhov saum npoo ntawm cov khoom yuav tsum tau pleev xim rau (tiv thaiv los ntawm ya raws).

Lub melting point ntawm duralumin yog li ntawm 650 degrees. Cov hlau yog lub teeb thiab siv tau, txhim khu kev qha thiab hnav-resistant. Nws tuaj yeem siv rau hauv cheeb tsam nrog txhua yam kev nyab xeeb. Qhov nrov ntawm cov khoom siv hlau yog vim lawv cov nqi qis.

Qhov tsis zoo ntawm duralumin

Txawm hais tias qhov kev ua tau zoo tshaj plaws, cov hlau muaj ntau qhov tsis zoo. Ua ntej, duralumin tsis tiv thaiv electrochemical raug. Qhov thib ob, nws tsis tuaj yeem ua ke nrog cam khwb cia hlau lossis hlau. Thib peb, lub melting point ntawm duralumin yog 50 degrees qis dua li ntawm txhuas. Lub tom kawg ua lub luag haujlwm tseem ceeb hauv kev tsim dav hlau lossis tsheb ciav hlau.

Production

Cov txheej txheem tsim cov hlau yog ua tiavCov cuab yeej siv high-tech: moj tej tawg furnaces, roasting chambers thiab ntau ntxiv. Cov hlau ua kua yog nchuav rau hauv pwm thiab muab tso rau hauv qhov hluav taws kub chamber. Nyob rau hauv cov txheej txheem no, cov alloy poob nws cov khoom thiab ua mos.

Tom qab ntawd, nws raug rau qhov txheej txheem kev laus. Nws kav tsis ntau tshaj 24 teev ntawm huab cua kub ntawm +20 degrees. Kuj tseem muaj cov txheej txheem kev laus. Ua li no, lub alloy yog muab tso rau hauv ib tug tshwj xeeb chamber. Cov txheej txheem yuav siv li 3-4 teev.

Note. Tsuas yog tom qab dhau los ntawm txhua theem ntawm kev tsim khoom ua duralumin tau txais lub zog siab thiab kev ntseeg siab.

Nws tsim nyog sau cia tias cov hlau alloy nrog cov txheej txheem kev laus yog suav tias yog cov khoom zoo dua. Nws lub neej kev pab cuam ntev npaum li cas ntawm cov hlau uas muaj hnub nyoog.
