Remelting ntawm kub, yog nws tsim nyog thiab nyob rau hauv dab tsi mob

Feem ntau, txhua tus neeg muaj mob rau hauv lawv lub neej thaum cov khoom siv kub kub nyhiab, thin chains tawg, ib qho ntawm ob kab, ib qho qhaub cij, poob, piv txwv. Los yog qhov kev kho kom zoo nkauj ua tsis tau, tawm ntawm kev zam ... Ib qho ntawm lub xam ntawm qhov teeb meem no yog, piv txwv li, remelting lub ib ncig ntawm kub mus rau ib tug tshiab piece ntawm hniav nyiaj hniav kub.

Ua ntej yuav txiav txim siab seb puas yuav yaj

Lub pob zeb kub ntawm nws tus kheej yog ib qho kev tshwm sim tsis zoo. Thiab qhov ntau unprofitable nws yuav, lub me qhov ceeb thawj ntawm remelted cov khoom. Qhov tseeb yog hais tias thaum muaj ib qho kev kho ntawm kub, muaj ib tug txheej txheem ntawm kev thev xov. Qhov ntim ntawm qhov txawv ntawm qhov txawv txav ncaj qha yog nyob ntawm tus qauv ntawm cov khoom (qhov tsawg dua tus qauv, qhov siab dua qhov Performance index) thiab tuaj yeem ncav cuag 10%. Yog li, yog tias qhov kev txiav txim siab zaum kawg los kho qhov khoom, nws yog qhov zoo dua los khaws cov khoom kub ntau tshaj li qhov ua tau, thiab tom qab ntawd mam muab rau lub rooj sib tham txog cov hniav nyiaj hniav kub.

Remelting ntawm cov khoom kub: ib tug neeg txoj kev

Muaj ob txoj kev ntawm melting kub, thiab nkawd ob leeg tsis muaj tej yam nyuaj nyuaj nyhuv:

1. Pib, cov khoom thiab cov seem seem ntawm hmoov av thiab av.
2. Tom qab ntawd, nrog rau ib txoj kev ntawm melting seem yog muab tso rau hauv ib lub khob tshwj xeeb los yog ib rab diav rau hauv yaj. Yuav kom sov lub hlau, ib qho roj hlab siv feem ntau yog siv.
3. Cov hlau ua tau ua ntej-alloyed mus rau hauv ib lub ingot rau ntxiv ua hauj lwm nrog nws, los yog nws muaj peev xwm tam sim ntawd poured rau hauv daim ntawv npaj.

Remelting kub: ib txoj hauv kev centralized

Lwm txoj kev ntawm melting kub yog hu ua centralized. Nyob rau hauv cov ntaub ntawv no, tsis ib lossis ob daim ntawm cov hniav nyiaj hniav kub yog melted, tab sis ib co kub seem ntawm txawv cov khoom nrog sib cais.

Ntawm no qhov kev ua tiav tiav yuav muaj kev sim sib txawv ntawm cov ntaub ntawv pib. Tus qauv yog txiav txim siab siv cov tshuaj tsom xam cov tshuaj tshwj xeeb tom qab txias ntawm cov hlau. Xws li kev kho kub tsis yog nrog kev pab los ntawm ib lub qhov cua kub - tshwj xeeb hluav taws xob furnaces nrog electrodes yog siv. Kuj, thaum lub sijhawm melting rau ib lub cav hlau ntxig, graphite hmoov siv los ntawm qhov hluav taws xob. Tseem muaj qhov cub sov so rau cov kub yaj, tiam sis lawv yuav tsum tau siv lawv los ntawm qhov ntsuas.

Lub sijhawm ntev npaum li cas thiab nws cov nqi

Muaj ntau ntau yam cuam tshuam rau ob lub sijhawm thiab tus nqi ntawm cov txheej txheem ntawm melting kub seem thiab ua ib qho tiav lawm hniav nyiaj hniav kub. Qhov no yog qhov tsis yooj yim ntawm cov khoom muag los ntawm tus neeg muas zaub, thiab hom kev kuaj pom yog kub kub rau kev txhim kho. Ntawm chav kawm, tsis yog qhov chaw kawg yog qhov kev txawj ntawm lub koob yees duab, leej twg yuav ua hauj lwm nrog cov khoom.

Qhov nruab nrab ntau lawm lub sij hawm yuav los ntawm ib tug ob peb teev - rau yaj ib tug yooj yim kub bar - thiab mus txog rau ob peb lub hlis, yog hais tias nws yog ib cov nyiaj ntawm ib tug complex weave thiab nrog inlays ntawm precious pob zeb.

Kuaj ntawm kub: dab tsi tshwm sim, dab tsi ua

Thiab thaum kawg, rau cov neeg tsis paub, kuv xav hais ob peb lo lus hais txog qhov kev xeem ntawv yog dab tsi. Nyob rau hauv nws tus kheej kub - hlau yog heev mos thiab tsis khov ua ntej tus ntawm lub cev lub cev. Yog li ntawd, rau txhua hnub hnav nws tsis haum, thiab muab nws ib lub fortress, raws li tau zoo raws li ib tug tshwj xeeb ruaj khov ntxoov ntxoo, kub yog fused nrog lwm hlau, xws li nyiaj, tooj liab, lwm yam zoo li

Yog li, tib cov qauv yog tus nqi ntawm cov kub ntshiab hauv cov khoom sib piv nrog rau tus nqi ntawm impurities lwm cov hlau. Peb tuaj yeem pom 6 qauv: 375, 500, 583, 585, 750, 958. Nqa, piv txwv, kuaj 375th. No tus lej txhais tau hais tias nyob rau hauv ib txhiab grams ntawm alloy ntawm pure kub tsuas yog 375 grams, thiab ntxiv 625 txheeb rau impurities. Zoo, raws li, 958th xeem - rau ib kilogram ntawm ntshiab kub hlau yuav account rau 958 grams, thiab rau impurities - tsuas yog 42 grams. Yog li cov nyiaj ntawm impurities yuav muab xam rau cov seem tshuav.
