Corundum Mullite Castable
Khoom Description
1. Raw khoom ntawm corundum mullite castables:
1. Corundum hais: High-purity corundum hais nrog ib tug loj ntawm 0 5-5 hli feem ntau yog siv.
2. Mullite particles: Xaiv cov khoom zoo mullite nrog rau qhov loj me me.
3. Binder: Feem ntau siv binders suav nrog Calcium Aluminate Cement (CAC) lossis lwm yam cement-free binders, nrog cov ntsiab lus tsawg, feem ntau yog nyob nruab nrab ntawm 1-3%.
4. Additives: Additives muaj xws li plasticizers, reinforcing agents, anti-release agents, thiab lwm yam, siv los txhim kho cov fluidity, tawg tsis kam thiab kev ua tau zoo ntawm castables.
Corundum mullite castable yog ua los ntawm xim av corundum thiab mullite aggregate raws li cov khoom xyaw tseem ceeb, dawb corundum hmoov, a-A1203 micro hmoov thiab mullite hmoov ua hmoov zoo, siv micro hmoov technology, ua ke nrog cov cement thiab ntxiv additives Ib tug unshaped refractory castable.

Cov txheej txheem tsim khoom
1. Sib tov cov hmoov qhuav: tag nrho sib xyaw corundum hais thiab mullite hais kom ntseeg tau tias muaj kev sib faib ntawm cov khoom.
2. Ntxiv binder: Maj mam ntxiv binder thaum lub sij hawm stirring, thiab ntxiv stirring kom nws tusyees dispersed nyob rau hauv cov hmoov.
3. Ntxiv cov additives: Maj mam ntxiv cov additives raws li xav tau, thiab xyuas kom meej tias lawv sib npaug sib npaug thaum lub sij hawm stirring.
4. Sib tov thiab humidification: Maj mam ntxiv dej rau qhov sib tov thiab do kom tsim nyog kom ua tau raws li qhov tsim nyog fluidity thiab kev ua haujlwm ntawm kev sib tov. Ua tib zoo saib xyuas cov dej kom tsis txhob muaj cov dej noo ntau dhau los cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.
5. Pouring thiab curing: Muab cov khoom sib xyaw ua ke sai sai rau qhov chaw ua ntej, thiab siv cov khoom siv vibration lossis vibration los tshem tawm cov npuas thiab qhov khoob. Tom qab ntawd, cov txheej txheem kho kom zoo thiab ziab kom qhuav yog ua raws li cov khoom siv tshwj xeeb kom ntseeg tau tias qhov ua tau zoo tshaj plaws ntawm Corundum mullite castable.
Cov khoom siv
1. Corundum mullite castable muaj refractoriness siab heev thiab tuaj yeem tiv taus qhov kub thiab txias nyob rau hauv ib puag ncig kub. Lawv feem ntau siv rau hauv cov khoom siv xws li cov cua kub kub, lub tank kub kub, thiab tooj liab alloy smelting furnaces.
2. Corundum-mullite castable muaj kev tiv thaiv zoo rau corrosive media xws li acid, alkali thiab ntsev. Hauv kev lag luam tshuaj lom neeg thiab metallurgical, lawv feem ntau siv rau hauv cov khoom siv uas ua rau cov roj corrosive thiab kua, xws li pickling tanks thiab furnace linings.
3. Corundum-mullite castable muaj cov thermal shock stability zoo heev, tuaj yeem tiv taus cov thermal kev nyuab siab los ntawm kev hloov pauv kub ceev, thiab tsis ua rau tawg thiab puas. Nyob rau hauv high-temperature metallurgy thiab iav industries, lawv feem ntau yog siv rau hauv ob sab phlu khoom siv xws li iav kilns, blast furnaces thiab smelting furnaces.
4. Corundum-mullite castable muaj qhov hnav tsis zoo thiab muaj qee yam tsis kam rau cov neeg kho tshuab hnav thiab cuam tshuam ntawm cov ntaub ntawv granular. Hauv kev lag luam xws li metallurgy, cement thiab thee, lawv feem ntau siv los ua cov ntaub ntawv hauv ob sab phlu rau cov khoom siv xws li steel flow systems, rotary kilns thiab coal gasifiers.
5. Corundum-mullite castable muaj cov thermal conductivity tsawg thiab muaj peev xwm ua tau zoo thiab ua kom sov. Nyob rau hauv high-temperature smelting thiab cua sov khoom, kev siv corundum-mullite castables yuav txo tau lub zog poob thiab kub hloov thiab txhim kho lub zog efficiency ntawm cov khoom.
