Refractory xav tau rau crucible ntawm induction melting rauv

Kev ua haujlwm ntawm lub crucible ntawm induction melting rauv yog qhov phem heev, thiab cov phab ntsa hauv ob sab phlu yog nyias, thiab sab hauv yog ncaj qha cuam tshuam los ntawm thermal cuam tshuam ntawm kub kub molten hlau thiab yaig ntawm cov kua slag. Lub zog stirring tsim nyob rau hauv qhov kev txiav txim ntawm lub electromagnetic teb ua rau lub Pershock phab ntsa yuav tsum tau eroded los ntawm cov hlau. Sab nrauv ntawm phab ntsa yog nyob rau hauv kev sib cuag nrog cov dej-txias induction coil, thiab qhov kub ntawm qhov sib txawv ntawm sab hauv thiab sab nraud yog loj. Txhawm rau ua kom lub neej ntawm lub cev qhuav dej, muaj cov kev cai nruj heev rau cov khoom siv refractory ua rau cov pa luam yeeb amber.

(1) Siab txaus siab kub kuj. Cov khoom siv refractory siv los ua cov crucible yuav tsum tiv taus qhov kub siab tshaj 1700 RON, thiab qhov kub ntawm qhov muag yuav tsum siab dua 1650 RON.

(2) Zoo thermal stability. Qhov kub ntawm cov phab ntsa crucible fluctuates zoo heev thaum lub sij hawm ua hauj lwm, thiab qhov kub thiab txias yog unevenly faib. Yog li ntawd, cov phab ntsa yuav txuas ntxiv tsim cov ntim expansion thiab contraction thiab ua rau cov kab nrib pleb, uas cuam tshuam ncaj qha rau kev pab cuam lub neej ntawm qhov nce.

(3) Cov khoom siv tshuaj lom neeg ruaj khov. Crucible cov ntaub ntawv yuav tsum tsis txhob hydrolyzed thiab pulverized nyob rau hauv qis kub, tsis yooj yim decomposed thiab txo nyob rau hauv high kub, thiab tsis yooj yim corroded los ntawm molten slag thiab molten hlau.

(4) Nws muaj cov khoom siv kho tshuab siab. Nws tuaj yeem tiv taus qhov cuam tshuam ntawm tus nqi ntawm chav tsev kub, thiab tuaj yeem tiv taus qhov kub siab ntawm cov hlau molten thiab muaj zog electromagnetic induction stirring nyhuv ntawm qhov kub thiab txias, thiab cov phab ntsa crucible tsis yooj yim rau scoured, hnav thiab corroded. Lub zog flexural siab ntawm qhov kub thiab txias kuj txhais tau hais tias cov refractory muaj zog tiv thaiv slag yaig thiab thermal vibration, uas yog ib qho tseem ceeb ntawm refractories, tshwj xeeb tshaj yog alkaline refractories.

(5) Cov thermal conductivity me me los txhim kho cov thermal efficiency ntawm lub cub tawg.

(6) Kev ua haujlwm zoo rwb thaiv tsev. Cov khoom siv crucible yuav tsum tsis txhob siv hluav taws xob nyob rau hauv qhov kub thiab txias, txwv tsis pub nws yuav ua rau kom tawg thiab luv Circuit Court thiab ua rau muaj xwm txheej. Nws raug nquahu kom siv cov sib nqus sib nqus kom tshem tawm cov neeg xyuas pib impurities sib xyaw hauv cov khoom siv refractory ua ntej siv.

(7) Cov khoom siv muaj kev tsim kho zoo thiab kho yooj yim, uas yog, kev ua haujlwm zoo sintering, yooj yim knotting thiab tu.

(8) Muaj peev txheej thiab tus nqi qis.

Nws yog ib qho nyuaj heev kom ua tiav tag nrho cov kev ntshaw saum toj no, tshwj xeeb tshaj yog nrog kev txhim kho ntawm metallurgy thiab foundry industries, lub peev xwm ntawm induction melting furnaces yog tas li nthuav, lub zog yog nce, thiab ntau yam smelting yog dav. Kev xav tau. Yog li ntawd, nws yog ib qho tseem ceeb heev rau kev tshawb fawb thiab tsim ntau yam ntawm cov ntaub ntawv refractory rau kev sib tsoo ntawm induction melting furnaces.
