Dab tsi ntawm induction rauv refractory ramming khoom siv rau aluminium master alloy?

Kev siv cov induction rauv refractory ramming cov ntaub ntawv nyob rau hauv master alloys Tsis ntev los no, ntau thiab ntau manufacturers ntawm induction rauv tswv alloys tau smelted, thiab cov yuav tsum tau rau induction rauv refractory ramming cov ntaub ntawv tau ua ntau dua thiab siab dua. Cov kev cai rau impermeability, refractoriness, corrosion kuj, thiab lwm yam yog ntau dua li cov kev cai yav dhau los, thiab peb kuj cia siab tias tus nqi yuav raug txo. Raws li kev xav tau ntawm kev lag luam thiab kev xav tau, cov khoom siv hluav taws xob kub kub tau dhau los ntawm kev tshawb nrhiav thiab kev sim tsis tu ncua. Tau ntse tsim ib tug xov tooj ntawm cov tswv alloy cov neeg muas zaub nyob rau hauv lub zos cheeb tsam, thiab tau tiav ib tug zoo lub koob npe nrov thiab yeej qhuas los ntawm cov neeg muas zaub. Tam sim no tus tswv alloys ntawm kev ua lag luam feem ntau yog ua los ntawm txhuas silicon, txhuas tooj liab, txhuas hlau, txhuas titanium boron thiab lwm yam. Qhov kub smelting feem ntau tsis siab npaum li cov hlau smelting, tab sis nws yog siab tshaj qhov kub ntawm txhuas smelting.

Vim tias muaj zog permeability ntawm txhuas, nws tuaj yeem drilled thaum koj pom cov seam, thiab cov kev ua ntawm txhuas yog siab heev, uas yog feem ntau yuav hloov cov tshuaj tiv thaiv. Yog li ntawd, ntau yam khoom siv hluav taws xob hauv ob sab phlu tsis tuaj yeem tsim nyob rau hauv ob peb lub qhov cub. Yog li, tam sim no nws yog ib qho uas siv graphite crucibles nrog induction rauv refractory ramming cov ntaub ntawv. Txawm li cas los xij, qhov tsis zoo ntawm cov khoom siv refractory ramming ntawm qhov cub induction zoo tib yam yog tias thaum lub graphite crucible tawg lawm, lub tshuab hluav taws xob yuav tsum raug tshem tawm, txwv tsis pub lub cub tawg yooj yim hnav. Peb cov khoom tsim tshiab refractory ramming rau induction rauv tsis tsuas yog siv ib leeg xwb tab sis kuj siv tau nrog graphite crucibles. Nyob rau hauv cov ntaub ntawv ntawm kev siv ua ke, txawm tias lub crucible yog yuam kev tawg thaum cov khoom qis dua cov khoom siv, nws yuav tsis cuam tshuam rau kev siv, nws tseem tuaj yeem siv tau txhua lub sijhawm, thiab tsis tas yuav txhawj xeeb txog lub hauv ob sab phlu. lub cub tawg, uas yuav tsis cuam tshuam rau kev ua haujlwm ib txwm muaj. Lwm cov nqi tsis siab. Txij li thaum nws pib, nws tau sai sai tau txais ib tug loj tus naj npawb ntawm cov tswv alloy cov neeg muas zaub los ntawm cov pej xeem qhuas cov neeg muas zaub.
