Solder, uas yog ib qho tseem ceeb ntawm kev sib txuas cov khoom siv hauv ntau qhov chaw xws li electronics, automotive, aerospace, thiab lwm yam, nws qhov zoo thiab kev ua tau zoo cuam tshuam ncaj qha rau kev ntseeg tau thiab ruaj khov ntawm cov khoom. Nrog rau kev nce qib ntawm cov thev naus laus zis tas li, qhov yuav tsum tau ua rau purity, microstructure, thiab kev ua haujlwm ntawm solder yog nce siab. Raws li cov khoom siv hlau zoo tshaj plaws, lub tshuab nqus tsev kab rov tav nruam casting tshuab tau maj mam nyiam nyob rau hauv kev lag luam solder, muab cov kev daws teeb meem zoo rau kev tsim cov khoom zoo.
1,Ua hauj lwm hauv paus ntsiab lus ntawmlub tshuab nqus tsev kab rov tav nruam casting tshuab
Lub tshuab nqus tsev kab rov tav nruam casting tshuab yog tsim los ntawm lub cub tawg, lub crystallizer, lub tshuab rub tawm, lub tshuab nqus tsev, thiab lwm yam. Ua ntej, muab cov khoom siv rau hauv lub qhov cub tawg thiab ua kom sov kom ncav cuag cov kua dej uas tsim nyog. Tom qab ntawd, qhov chaw casting raug tshem tawm mus rau ib qho twg los ntawm lub tshuab nqus tsev kom txo tau qhov sib xyaw ntawm cov roj impurities. Nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus thiab sab nraud siab, kua solder ntws mus rau hauv kab rov tav tso crystallizer, uas yog txias los ntawm circulating dej kom maj mam solidify thiab crystallize ntawm nws sab hauv phab ntsa, tsim ib lub plhaub. Nrog rau qhov qeeb traction ntawm cov cuab yeej casting, cov kua roj hmab tshiab tau txuas ntxiv mus rau hauv cov crystallizer, thiab lub plhaub khov kho tau txuas ntxiv rub tawm, yog li ua tiav cov txheej txheem nruam nruam.

2,Qhov zoo ntawm Nqus Kab rov tav Nruam Casting Tshuab
(1)Txhim kho solder purity
Casting nyob rau hauv lub tshuab nqus tsev ib puag ncig tuaj yeem tiv thaiv cov roj impurities xws li oxygen thiab nitrogen los ntawm kev nkag mus rau hauv lub solder, txo qhov tsim ntawm oxide inclusions thiab pores, txhim kho qhov purity ntawm solder, thiab txhim kho nws cov ntub dej thiab flowability thaum lub sij hawm vuam txheej txheem, yog li txhim kho. qhov zoo ntawm welded sib koom.
(2)Txhim kho microstructure ntawm cov khoom siv solder
Thaum lub sij hawm lub tshuab nqus tsev kab rov tav nruam casting txheej txheem, lub solidification tus nqi ntawm cov kua solder yog sib xws, thiab cov cua txias yog tswj tau, uas yog conducive rau tsim ib tug uniform thiab nplua grain qauv thiab txo segregation phenomena. Lub koom haum zoo li no ua rau cov khoom siv ntawm cov khoom siv tau ruaj khov dua, xws li lub zog tensile thiab elongation, uas tau txhim kho thiab ua tau raws li qee qhov kev thov rau kev ua haujlwm zoo.
(3)Ua haujlwm tas li ntau lawm
Piv nrog rau cov txheej txheem casting ib txwm, lub tshuab nqus tsev kab rov tav nruam casting tshuab tuaj yeem ua tiav kev tsim khoom tas mus li thiab tsis cuam tshuam, txhim kho kev ua haujlwm zoo heev. Nyob rau tib lub sijhawm, nws muaj cov qib siab ntawm automation, txo cov kauj ruam ntawm kev ua haujlwm, txo qis kev siv zog thiab cov nqi tsim khoom, thiab ua rau cov txheej txheem ntau lawm ruaj khov thiab txhim khu kev qha, uas yog qhov tsim nyog rau kev tswj xyuas cov khoom zoo.
(4)Txo cov khoom siv pov tseg
Vim yog cov txheej txheem nruam nruam thiab kev tswj xyuas qhov loj thiab cov duab ntawm lub billet, piv rau lwm txoj kev casting, nws tuaj yeem siv tau cov ntaub ntawv raw, txo cov khoom pov tseg los ntawm kev txiav, machining nyiaj, thiab lwm yam, txhim kho kev siv tus nqi ntawm raw cov ntaub ntawv, thiab txo cov nqi tsim khoom.
3,Cov ntawv thov tshwj xeeb hauv kev lag luam solder
(1)Cov txheej txheem ntau lawm
Hauv kev tsim cov khoom siv, thawj kauj ruam yog txhawm rau sib xyaw cov khoom xyaw uas yuav tsum tau ua thiab ntxiv cov ntaub ntawv npaj rau hauv lub tshuab nqus tsev vacuum kab rov tav nruam casting tshuab. Pib lub tshuab nqus tsev, txo lub siab nyob rau hauv lub cub tawg mus rau ib tug haum lub nqus tsev vacuum theem, feem ntau ntawm kaum ntawm pascals thiab pua pua ntawm cov pascals, ces kub thiab yaj lub solder thiab tuav ib tug ruaj khov kub. Kho qhov ceev nrooj thiab cov dej txias ntim ntawm cov crystallizer kom ntseeg tau tias cov kua solder solidifies uniformly nyob rau hauv lub crystallizer thiab yog tujtaws rub tawm, tsim ib co specification ntawm solder billet. Cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
(2)Txhim kho qhov zoo ntawm cov khoom siv solder
Noj Sn Ag Cu tsis muaj hmoov txhuas feem ntau siv hauv kev lag luam hluav taws xob ua piv txwv, thaum tsim siv lub tshuab nqus tsev kab rov tav nruam casting, cov ntsiab lus oxygen hauv lub tshuab tuaj yeem tswj tau nruj me ntsis ntawm qib qis, tsis txhob muaj impurities xws li tin slag. tshwm sim los ntawm oxidation thiab txhim kho tus nqi siv tau zoo ntawm cov solder. Nyob rau tib lub sijhawm, ib lub koom haum kev sib koom ua ke ua rau cov khoom siv los ua kom zoo dua cov khoom me me sib koom ua ke thaum lub sij hawm micro soldering txheej txheem ntawm cov khoom siv hluav taws xob, txo cov vuam tsis xws li cov khoom siv hluav taws xob thiab kev sib txuas, thiab kev txhim kho vuam kev ntseeg tau thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob.
Nyob rau hauv cov txheej txheem brazing ntawm kev lag luam automotive, rau high-strength aluminium raws li solder, lub solder uas ua los ntawm lub tshuab nqus tsev kab rov tav nruam casting tshuab muaj zoo zog thiab corrosion kuj. Nws cov qauv lis niaj hnub ua kom muaj kev ruaj ntseg ntawm cov khoom siv thaum lub sij hawm kub kub brazing, uas tuaj yeem txuas cov khoom siv tsheb ruaj khov thiab txhim kho tag nrho cov kev ua tau zoo thiab kev pabcuam lub neej ntawm cov khoom siv tsheb.
(3)Daim ntawv thov piv txwv
Ib tug paub zoo solder ntau lawm enterprise tau qhia ibnqus theem nruam casting tshuab, uas tau nce purity ntawm nws cov tin lead solder khoom los ntawm 98% mus rau ntau tshaj 99.5%, thiab txo cov ntsiab lus ntawm oxide inclusions. Nyob rau hauv daim ntawv thov vuam ntawm hluav taws xob Circuit Court boards, qhov vuam tsis ua hauj lwm tus nqi tau txo los ntawm 5% mus rau tsawg tshaj li 1%, zoo heev txhim kho kev lag luam kev sib tw ntawm cov khoom.
