(1) sib koom ua kev lag luam huv huv
Kev siv cov hluav taws xob muaj hlau los yog cov khov me me (C loj feem ntau yog ≤ 0.15%) los ntxuav lub chaw rauv taws muaj lub luag haujlwm tseem ceeb. Ua ntej tshaj plaws, ntxuav lub nqi muaj lub siab melting point thiab tsawg liquidity, tuaj yeem txo cov kua hlau kom tawg kev nkag mus, thiab siv cov kauj vuam ntiag sintering. Qhov thib ob, qhov kub siab ntawm cov hlau uas tawg tau nthuav cov thickness ntawm sintered txheej, uas yog qhov tshwj xeeb tshaj yog qhov tseem ceeb rau qhov kub sintering crucibles. Thaum kawg, feem ntau ntawm cov neeg tsis muaj peev xwm nyob rau hauv cov tshiab crucible yuav tshwm sim nyob rau hauv thaum ntxov ua sawv ntawm smelting. Thaum ib qho kev sib tawg lawm, cov hlau ua muaj hlau yuav muaj qhov chaw siab melting thiab tsis muaj kua qoob loo yuav tsum yooj yim pov tseg.
(2) Lub pob zeb tshiab tsis tuaj yeem ua kom hlau nrog zoo fluidity
Tus tshiab crucible 5 yuav tsum tsis txhob npaj ua ntej smelting siab carbon, siab tsiv, siab silicon thiab high hlau alloy steel. Yuav kom tiv thaiv cov hlau kua los ntawm nkag mus rau lub keej ob hlau ntes tshwm sim. Cov txheej txheem pib muaj peev xwm ua kom tsw muaj roj carbon tsawg chromium hlau.
(3) Tus nqi them nyiaj tau los tshiab kom paub tseeb tias qhov kev vam meej ntawm kev txhim kho.
Cov ntaub ntawv tshiab crucible, chaw thau khoom yuav tsum muaj kev nyuab siab dua, tshem tawm lub sijhawm melting "bridging." Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev cuam tshuam loj heev rau ntawm phab ntsa. Chaw thau khoom mus txog qhov siab kawg, mus cuag lub sij hawm smelting.
(4) Lub pob zeb tshiab ua kom zoo zoo nyob rau hauv cov txheej txheem smelting
Ntxiv nrog rau kev ceev faj ntawm crucible tshiab, tab sis tseem ceev faj soj ntawm lub precursor ntawm breakout. Feem ntau saib cov phab ntsa puas yog seb puas muaj xim txawv; txawm tias qhov kev pab cuam muaj hluav taws xob hloov mus, qhov tam sim no yog hloov mus rau pem suab. Anomalies yuav tsum tau kuaj xyuas tam sim ntawd. Yuav kom tsis txhob muaj kev raug yuam hlau hlau. Nyob rau tib lub sij hawm, yuav tsum tau soj ntsuam qhov kev sib tw inductor ntawm qhov rwb thaiv tsev yog qhov zoo.
(5) tshiab crucible tom qab tapping crucible tshuaj xyuas
Tom qab tapping lub sab hauv ntawm lub crucible yuav tsum tau xyuas seb puas muaj teeb ci los yog kab tawg, tshwj xeeb tshaj yog cov voj voog tawg, cov kab ntsig feem ntau yog tsawg dua teeb meem. Lub sij hawm tu thiab kho cov kab tsis zoo
