(1) Kev npaj rau lub cub tawg yaj
(2) Lub lub cub tawgcua sov yuav tsum ua tiav ua ntej ntxiv cov ntaub ntawv thiab txhua yam khoom siv rauv taws yuav tsum tau npaj.
Nws yuav tsum tau cua sov thaum lub cub tawg tshiab lossis kho dua lossis tsum tsis txhob tsim khoom.
(3) Cov khoom xyaw thiab kev npaj
1. Kev xaiv cov khoom siv raw yuav tsum raug tswj hwm nruj me ntsis;
2. Cov khoom siv raw uas xav tau rau cov khoom xyaw, suav nrogcov hlau txhuas,cov magnesium ingots, metal silicon, cov khoom sib xyaw thiab lwm yam khoom xyaw yuav tsum yog cov khoom ntshiab. Yog tias tsis muaj cim meej, yuav tsum tau coj mus kuaj kom paub tseeb tias cov khoom xyaw yog dab tsi ua ntej siv;
3. Cov khoom seem theem ib: cov taub hau thiab cov tw ntawm cov khoom siv casting hauv lub chaw ua haujlwm casting, thiab cov txhuas seem uas nyob hauv lub cub tawg, yuav tsum tau tshuaj xyuas cov khoom sib xyaw thiab kuaj cov qauv;
4. Cov hlau txhuas: qib tsis tsawg dua 99.9%;
5. Cov hlau nplaum Al-Si uas ua rau nws tus kheej, txhua lub cub tawg muaj cov tshuaj lom neeg muaj nqis;
6.Tooj liab, chromium,hlau, manganese,titaniumthiab lwm yam khoom siv hlau ntxiv yuav tsum yog raws li feem pua ntawm cov ntsiab lus uas lawv cov neeg muab khoom muab;
7. Cov khoom siv raw uas muaj cov ntsiab lus saum toj no yuav tsum qhuav, huv si, thiab tsis muaj dej, av, roj, thiab lwm yam.
(4) Cov kev cai rau kev siv cov khoom siv raw thiab cov ntaub ntawv pabcuam
1. Cov hlau txhuas muaj ntau tshaj 99.90% Al, cov hlau txhuas-silicon yog qib peb lossis siab dua, cov hlau magnesium yog qib peb lossis ntau dua, nitrogen yog 99.99%,txhuas titanium boron hlau muaj ntau tshaj 5% titanium,cov dej khib nyiab, cov kua dej ua kom huv, thiablim dej ua npuas ncauj yuav tsum ua raws li cov cai tswjfwm cuam tshuam.
2. Ntxiv cov khoom siv raw: Mg - nyob rau hauv daim ntawv ntawm magnesium ntshiab, Si - nyob rau hauv daim ntawv ntawm master alloy, Ti - nyob rau hauv daim ntawv ntawm txhuas titanium boron hlau
(5) Kev Pub Noj
1. Ua ntej pub cov khoom siv, xyuas seb lub cub tawg puas huv. Siv lub diav ntxuav lub cub tawg los ntxuav cov slag thiab oxides ntawm phab ntsa, ces kaum ntawm lub cub tawg, thiab hauv qab ntawm lub cub tawg;
2. Tom qab lub cub tawg raug nres, yog tias nws nyob hauv lub cub tawg txias, lub cub tawg yuav tsum tau preheated kom lub cub tawg kub txog li 700 ~ 800 ℃;
3. Ua ntej ntxiv cov khoom seem lossis lwm yam khoom seem kom tsim nyog los ua lub hauv paus. Nws yog qhov zoo tshaj plaws los ntxiv nws mus rau kwv yees li 500 hli ntawm qhov chaw pub mis. Tom qab ntawd ntxiv cov khoom seem loj xws li thiab hlawv tib lub sijhawm. Tom qab hlawv, cov khoom siv hauv paus hauv lub cub tawg yuav poob sai sai. Qee cov khoom seem loj yuav tsum tau ntxiv rau lub sijhawm, thiab tom qab ntawd yuav tsum tau ntxiv cov txhuas ingots. Tom qab pib ntxiv cov txhuas ingots, kev pub mis tuaj yeem ua tas mus li lossis intermittently, tab sis kev pub mis yuav tsum khaws lub sijhawm cub tawg khoob tsis pub tshaj 400 hli, thiab cov txhuas ingots yuav tsum tau ntxiv tam sim ntawd, tom qab ntawd ntxiv cov khoom seem loj thiab kaw lub hau cub tawg. Tom qab yaj tiav lawm, tig lub hau rau kwv yees li 20 feeb thiab do, tom qab ntawd pib ntxiv cov khoom seem me me xws li cov khoom seem. Tib lub sijhawm, qhov khoob ntawm lub cub tawg yuav tsum khaws cia me me kom txog thaum cov khoom seem raug ntxiv tag nrho thiab lub hau cub tawg tuaj yeem kaw.
(6) Cov lus ceeb toom rau cov neeg ua haujlwm pub mis
1. Yuav tsum tau ua tib zoo saib lub sijhawm ntawm lub cub tawg kom tau cov khoom siv ntxiv raws sijhawm. Vim tias yog lub sijhawm ntawm lub cub tawg ntev dhau, nws yuav tsis tsuas yog ua rau qhov kub ntawm cov pa luam yeeb nce ntxiv xwb, tab sis kuj ua rau kev siv hluav taws xob ntau ntxiv, ua rau qhov kub ntawm qhov chaw pub mov nce ntxiv, thiab ua rau qhov chaw ua haujlwm tsis zoo. Ntxiv mus, lub cub tawg yuav kub dhau thiab lub hauv paus ntawm lub cub tawg yuav raug hlawv.
2. Qhov kev txiav txim ntawm kev pub mov tsis tuaj yeem hloov pauv yam tsis tau xav tseg. Yog tias koj ntxiv cov txhuas ingots ua ntej yam tsis tau ntxiv cov seem rau hauv qab, hauv qab ntawm lub cub tawg yuav puas sai sai. Yog tias cov txhuas ingots hloov feem ntau cov seem raug ntxiv zaum kawg, lub sijhawm yaj yuav ntev dua. Yog li ntawd, lub sijhawm khoob ntawm lub cub tawg ntev dua, uas cuam tshuam rau lub neej ntawm lub cub tawg, ua rau kev siv hluav taws xob ntau dua, thiab ua rau kev poob hluav taws kub ntau dua. Cov hlau refractory ingots tuaj yeem ntxiv ncaj qha tom qab muab cov ntaub ntawv, xws li silicon, manganese, tooj liab, thiab lwm yam, kom cov hlau alloy ingots yuav raug nias rau hauv qab cov hlau aluminium ingot kom maj mam yaj, txo nws qhov kev poob hluav taws kub. Cov hlau uas yooj yim yaj thiab hlawv xws li magnesium ingots, raug ntxiv ncaj qha rau cov kua txhuas los ntawm lub qhov rooj cub tawg.
3. Ua tib zoo saib xyuas qhov kub ntawm lub cub tawg, qhov kub ntawm cov kua txhuas hauv lub pas dej ua kom yaj, qhov ceev ntawm kev yaj, lub zog ntawm lub cub tawg, qhov kub ntawm nplaim taws thiab cov xwm txheej ntawm cov khoom siv hauv lub cub tawg txhua lub sijhawm, yog li ntawd kom kho qhov loj ntawm nplaim taws kom tiv thaiv kev puas tsuaj rau cov khoom siv thiab kev tsim cov khoom pov tseg;
4. Thaum lub sijhawm them hluav taws xob ib txwm muaj, yog tias lub roj teeb hauv lub cub tawg tsis poob ntev thiab nplaim taws tawm ntawm qhov chaw them hluav taws xob, tej zaum cov khoom ntawd daig hauv lub cub tawg. Koj yuav tsum siv ib tug pas hlau los ntaus nws tam sim ntawd los ntawm sab saum toj ntawm lub cub tawg. Yog tias qhov no tsis ua haujlwm, koj yuav tsum tua lub tshuab khaws cua sov, siv lub tshuab hlawv kom cua sov kom tiv thaiv cov txhuas uas yaj kom tsis txhob kub dhau kom txog thaum lub roj teeb poob. Lub sijhawm no, koj yuav tsum ceev faj txog cov txhuas uas yaj uas yaj yuav tawg rau ntawm lub qhov rooj cub tawg thiab ua rau tib neeg raug mob.
(7) Kev kub hnyiab thiab kev kho kom haum rau lub cub tawg
1. Kaw lub qhov cua, qhib lub qhov rooj cub tawg thiab lub hau sab saum toj, pib lub kiv cua kom tshuab cov roj uas tau sau tseg hauv lub cub tawg, thiab tua lub kiv cua;
2. Tua hluav taws los ntawm qhov chaw tua hluav taws, maj mam tig lub kiv cua, qhib lub qhov roj thiab tom qab tua hluav taws tiav lawm, kho qhov ntau ntawm cov roj thiab cua kom me ntsis nplaim taws thiab me ntsis pa luam yeeb raug tso tawm ntawm lub cub tawg. Kaw lub qhov rooj cub tawg thiab nkag mus rau hauv kev smelting ib txwm muaj.
3. Yaj
Thaum lub sijhawm ua kom sov thiab yaj, yuav tsum do ntau zaus, thiab txav cov hlau txhuas loj uas tsis tau yaj mus rau thaj chaw kub siab kom ua kom yaj sai dua. Tom qab tag nrho cov khoom siv yaj tag (qhov kub ntawm cov txhuas yaj yuav tsum tsis pub tshaj 730 ~ 750 ° C thaum lub sijhawm no). Siv ib txheej ntawm cov dej ntws los cais cov txhuas slag thiab ntxuav cov slag ntawm qhov chaw ntawm cov kua txhuas. Tom qab ntawd muab cov silicon thiab magnesium ingots rau hauv cov kua txhuas. Ntxiv cov magnesium ingot thiab do kom sib npaug. Siv lub spatula los nias cov magnesium ingot hauv qab cov kua txhuas kom tiv thaiv kev puas tsuaj hlawv.
(8) Do
1. Tom qab ntxiv cov hlau ntxiv thiab magnesium ingot thiab yaj tag, cov yaj yuav tsum tau do kom sib npaug thiab ua kom huv si. Thaum lub sijhawm do, lub spatula yuav tsum tsis txhob raug rau ntawm qhov chaw ua kua thiab yuav tsum txav mus zoo kom tshem tawm cov ces kaum tuag;
2. Yuav kom paub tseeb tias cov khoom sib xyaw ua ke thiab txuas ntxiv mus, lub sijhawm nplawm yuav tsum yog 30 feeb.
(9) Kev ua kom zoo dua
1. Siv 2 lub raj mis nitrogen rau txhua lub cub tawg uas ua los ntawm cov txhuas uas yaj, kho qhov siab kom txog 0.3 ~ 0.5mpz, thiab ua kom npau rau 20 ~ 25 feeb. Cov yeeb nkab tso pa tawm txav mus los zoo nyob rau pem hauv ntej ntawm lub pas dej uas yaj yam tsis muaj qhov chaw khoob. Cov txheej txheem ua kom huv yuav tsum yog ua kom huv. Qhov kub ntawm cov txhuas uas yaj hauv lub cub tawg yuav tsum nyob rau hauv qhov ntau ntawm 730 txog 750 ° C;
2. Tom qabkev ua kom huv si yog txau tshuaj, cov pa nitrogen yuav tsum txuas ntxiv mus li ib feeb kom tshem tawm cov kua dej seem hauv cov yeeb nkab tag nrho, thiab tom qab ntawd cov yeeb nkab refining yuav tsum tau tshem tawm ntawm cov yaj thiab cov pa nitrogen yuav tsum tau tua;
3. Tom qab ua kom zoo, qhov saum npoo yuav tsum tau tshem tawm thiab ib txheej ntawmkev npog dej ntwsyuav tsum tau sprinkled rau ntawm qhov chaw yaj.
(10) Kho cov khoom xyaw
Cov txiaj ntsig ntawm kev xeem yuav tsum ua raws li cov kev cai ntawm "Tus Qauv Tswj Xyuas Sab Hauv rau Cov Tshuaj Lom Zem ntawm Cov Khoom Siv Aluminium"
