Lub Npe: Qhov Tseem Ceeb ntawm Cov Cub Hluav Taws Xob Induction Hauv Cov Hlau Smelting

Thaum smelting alloys, cov txheej txheem yuav tsum tau ua kom raug thiab tswj hwm kom ntseeg tau tias cov khoom xav tau tau ua tiav. Ib qho tseem ceeb ntawm cov txheej txheem no yog kev siv lub tshuab nqus tsev induction cub tawg. Cov cub tawg no ua lub luag haujlwm tseem ceeb hauv kev smelting ntau yam alloys, txhua tus muaj nws tus kheej cov kev xav tau tshwj xeeb. Hauv cov blog no, peb yuav tshawb nrhiav ntau hom alloys uas yuav tsum tau smelted hauv ib qholub tshuab nqus tsev induction cub tawgthiab cov laj thawj tom qab lawv qhov tsim nyog.

Ib qho ntawm cov hlau sib xyaw uas siv lub tshuab nqus tsev yog cov hlau tsis xeb. Cov hlau tsis xeb yog cov hlau sib xyaw uas siv tau ntau yam, txij li cov khoom siv hauv chav ua noj mus txog rau cov tshuab ua haujlwm hauv kev lag luam. Cov txheej txheem smelting ntawm cov hlau tsis xeb xav tau kev tswj hwm qhov sib xyaw ntawm cov hlau sib xyaw thiab tshem tawm cov khoom tsis huv xws li carbon thiab sulfur. Cov tshuab nqus tsev muab ib puag ncig zoo tshaj plaws rau kev smelting hlau tsis xeb vim tias lawv tuaj yeem tswj tau qhov kub thiab huab cua thaum lub sijhawm smelting.

Lwm cov hlau tseem ceeb uas yaj siv lub tshuab nqus tsev yog platinum-rhodium alloy. Platinum-rhodium alloy yog paub txog nws qhov muaj zog thiab qhov hnyav thiab tiv taus corrosion, ua rau nws yog cov khoom siv muaj txiaj ntsig rau kev lag luam xws li aerospace thiab cov khoom siv kho mob. Kev yaj platinum-rhodium alloy xav tau kev huv siab vim tias txawm tias cov khoom me me tuaj yeem cuam tshuam rau nws cov khoom. Lub tshuab nqus tsev muaj peev xwm tsim tau ib puag ncig huv siab uas xav tau los yaj platinum-rhodium alloy, ua rau lawv tseem ceeb rau kev tsim cov hlau muaj txiaj ntsig no.

Hauv kev lag luam aerospace, cov superalloys muaj kev xav tau ntau rau lawv lub peev xwm los tiv taus qhov kub thiab txias heev. Cov alloys no yog siv rau hauv kev tsim cov hniav turbine, cov khoom siv cav thiab lwm yam khoom tseem ceeb rau dav hlau thiab spacecraft. Kev yaj cov alloys kub siab xws li Inconel thiab Hastelloy xav tau kev tswj hwm meej ntawm cov txheej txheem yaj thiab khov thiab tshem tawm cov khoom tsis huv. Cov cub tawg induction nqus tsev muab cov xwm txheej tsim nyog rau kev yaj cov alloys kub siab los tsim cov khoom siv zoo, ua tau zoo rau kev siv aerospace.

Hauv kev lag luam tsheb, cov hlau txhuas siv dav vim lawv lub teeb thiab tiv taus xeb. Kev yaj cov hlau txhuas yuav tsum tau tswj hwm cov txheej txheem yaj thiab casting kom ntseeg tau tias cov khoom siv kho tshuab xav tau. Cov cub tawg nqus tsev muab kev tswj qhov kub thiab txias thiab huab cua uas xav tau los yaj cov hlau txhuas, uas yog qhov tseem ceeb rau kev tsim cov khoom siv tsheb zoo.

Hauv kev lag luam kho mob, cov khoom sib xyaw ua ke xws li titanium alloys thiab cobalt-chromium alloys yog siv rau hauv kev tsim cov khoom cog thiab cov khoom siv kho mob. Kev sib xyaw cov khoom sib xyaw no xav tau qib siab ntawm kev huv thiab kev tswj hwm ntawm cov khoom sib xyaw kom ntseeg tau tias lawv ua tau raws li cov kev cai nruj rau kev sib xyaw ua ke thiab cov khoom siv kho tshuab. Cov cub tawg nqus tsev muab cov xwm txheej tsim nyog rau kev sib xyaw ua ke ntawm cov khoom sib xyaw ua ke, ua rau lawv tseem ceeb rau kev tsim cov ntaub ntawv kho mob.

Hauv kev lag luam hluav taws xob, cov hlau tooj liab yog siv rau lawv cov hluav taws xob conductivity thiab thermal zog. Kev smelting hlau tooj liab yuav tsum tau tswj hwm qhov tseeb ntawm cov khoom sib xyaw thiab tshem tawm cov khoom tsis huv kom ntseeg tau tias cov khoom hluav taws xob thiab cov khoom siv kho tshuab tau raws li qhov xav tau. Lub tshuab nqus tsev induction muab ib puag ncig zoo tagnrho rau kev smelting hlau tooj liab los tsim cov khoom siv zoo rau kev siv hluav taws xob.

Hauv kev xaus, cov cub tawg induction nqus tsev ua lub luag haujlwm tseem ceeb hauv kev yaj ntawm ntau yam alloys, txhua tus muaj nws tus kheej cov kev xav tau tshwj xeeb. Los ntawm stainless hlau mus rau titanium, los ntawm cov alloys kub siab mus rau aluminium alloys, los ntawm biocompatible alloys mus rau tooj liab alloys, cov cub tawg no muab cov xwm txheej tsim nyog rau kev tsim cov khoom siv zoo rau ntau yam lag luam. Kev tswj qhov kub thiab txias meej, huab cua thiab kev huv si ua tiav los ntawm kev nqus tsev induction melting yog qhov tseem ceeb rau kev ua tau raws li cov kev cai nruj ntawm cov alloys niaj hnub. Raws li thev naus laus zis txuas ntxiv mus, lub luag haujlwm ntawm cov cub tawg induction nqus tsev hauv alloy smelting yuav tsuas yog qhov tseem ceeb dua hauv kev ua kom tau raws li cov kev xav tau ntawm ntau yam lag luam.
