Induction Rauv Refractory Hauv ob sab phlu
Induction Rauv Refractory Lining yog cov khoom siv thermal rwb thaiv tsev siv nyob rau hauv nruab nrab zaus induction cua sov rauv hauv ob sab phlu rau forging.
Muaj plaub yam tseem ceeb ntawm induction rauv Refractory Linings:
- Cov khoom siv hauv cov khoom siv acidic furnace. Nws cov khoom tseem ceeb yog quartz xuab zeb, uas yog pheej yig, muaj zog rwb thaiv tsev kev ua tau zoo, tsis tshua muaj kev tsim kho, thiab tsis tshua muaj qhov tsis xws luag thaum siv, ua kom ruaj khov dua. Peb cov khoom ntawm induction rauv cua sov rauv hauv ob sab phlu feem ntau yog siv cov khoom siv hauv cov khoom siv acidic, feem ntau yog tsim los ntawm silicon dioxide thiab txhuas oxide. Peb siv high-grade acidic rauv cov ntaub ntawv npaj nrog fused quartz ua cov khoom siv hauv paus. Cov ntsiab lus ntawm silicon dioxide yog ntau dua 99%, thiab qhov hluav taws kub tsis kam yog zoo dua qub piv rau cov khoom siv hluav taws xob zoo tib yam hauv cov khoom siv hluav taws xob, mus txog qhov melting point. Thaum tshav kub kub, yuav tsis muaj qhov hloov pauv loj thiab tsis muaj qhov hloov pauv theem nrab, txhim kho qhov ruaj khov ntawm lub qhov cub hauv ob sab phlu. Nyob rau hauv cov nqe lus ntawm kev sib khi txoj kev, muaj ob lub ntsiab ntawm binders. Ib qho yog siv cov iav dej sib txuas thaum qhov kub siab tshaj 1250 degree, thiab lwm qhov yog siv phosphoric acid sib txuas thaum qhov kub siab tshaj 1250 degree.
- Cov khoom siv hluav taws xob nruab nrab. Lub ntsiab tivthaiv yog dawb corundum, uas muaj ib tug melting point ntawm 2050 degree, siab hardness, hnav tsis kam thiab kub tsis kam, thiab yog haum rau high-temperature cam khwb cia hlau los yog loj rauv hauv ob sab phlu. Nws qhov tsis zoo yog kev hloov pauv theem siab thiab thermal expansion coefficient. Thaum siv, spinel micro hmoov tuaj yeem muab ntxiv los txhim kho corrosion kuj thiab seem stability. Kev siv cov khoom nruab nrab knotting yog txiav txim siab raws li qhov kub thiab txias. Thaum kub qis dua 1200 degree, av nplaum castables yog siv; Kub ntawm 1250 degree -1350 degree, siv cov khoom siv aluminium siab; Thaum qhov kub siab tshaj 1350 degree, siv corundum raws li cov khoom siv knotting.
- Alkaline rauv hauv ob sab phlu. Feem ntau siv magnesium xuab zeb qhuav ramming molding, nrog rau qhov hluav taws kub tsis kam mus txog 2800 degree, thiab corrosion kuj, kev pab lub neej ntev, thiab tus nqi qis. Nws qhov tsis zoo yog tias nws muaj cov coefficient siab ntawm kev nthuav dav thiab nws yooj yim rau kev tawg. Ntxiv cov hmoov dawb corundum los yog spinel hmoov thaum siv tuaj yeem txhim kho cov kev tsis txaus no thiab yog li ua rau nws lub neej ua haujlwm. Yog tias nws nyob hauv ib puag ncig alkaline, magnesium refractory binding khoom yuav tsum tau siv. Yog tias qhov kub thiab txias siab dhau lawm, magnesium khi cov khoom siv nrog lub ntiajteb txawj nqus tshwj xeeb tuaj yeem xaiv. Magnesium-based knotting cov ntaub ntawv yuav tsum tsis txhob muab cia rau sab nraum zoov lossis raug dej, txwv tsis pub lawv yuav pulverize.
- Spinel rauv hauv ob sab phlu. Qhov no yog ib hom tshiab ntawm cov khoom siv hauv cov khoom siv hluav taws xob, tsim siv alumina thiab magnesium oxide, thiab ua ke rau hauv spinel los ntawm kev kub kub tua hluav taws. Tam sim no, txoj kev loj hlob tseem ceeb yog qhov loj nruab nrab zaus rauv hauv ob sab phlu thiab kub-kub rauv hauv ob sab phlu.
Thaum xaiv cov khoom ntawm induction rauv Refractory Lining, nws yog ib qho tsim nyog yuav tau xav txog cov txheej txheem tsim khoom thiab cov khoom. Yog tias koj muaj lus nug, thov koj xav tiv tauj peb txhua lub sijhawm, thiab peb yuav muab cov lus teb rau koj!
