Tsis-stick aluminium castable
Cov ntaub ntawv tseem ceeb ntawm non-stick aluminium castables
Cov ntaub ntawv no yog ib yam tshiab ntawm cov khoom siv uas tsis tshua muaj cement thiab ultrafine hmoov ua ke raws li high-purity mullite, andalusite thiab sillimanite.Vim kev sib xyaw ua ke ntawm cov khoom siv raw thiab cov khoom siv hluav taws xob muaj txiaj ntsig zoo, muaj zog, thiab zoo thermal poob taus.ntsev, thiab lwm yam), tuaj yeem txo qhov ntub dej ntawm aluminium thiab alloys thiab slag rau refractory cov ntaub ntawv, thiab txhim kho corrosion kuj, yaig tsis kam, thiab tsis-sticking ntawm aluminium refractory cov ntaub ntawv rau txhuas kua uas muaj tshuaj lom neeg xws li ntsev thiab flux.Lub slag thiab slag muaj nuj nqi tiv thaiv aluminium thiab alloys thiab slag los ntawm kev nkag mus rau hauv cov ntaub ntawv refractory, prolongs lub neej ntawm lub qhov cub hauv ob sab phlu.Zoo tagnrho rau melting furnaces, static furnaces, launders, aluminium cladding linings.
