Dab tsi yog Refractories?

Refractory yog ib yam khoom siv uas tuaj yeem ua kom nws cov qauv thiab kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias. Lawv muaj qhov kub thiab txias tsis kam thiab thermal poob siab, thiab tuaj yeem tiv taus huab cua xws li kub kub, thermal shock thiab tshuaj yaig. Cov ntaub ntawv refractory yog dav siv hauv metallurgy, tshuaj lom neeg kev lag luam, kev tsim kho, lub zog thiab lwm yam kev lag luam, rau kev tsim cov refractory furnace, refractory hauv ob sab phlu, refractory rwb thaiv tsev cov ntaub ntawv.
Feem ntau refractories muaj xws li cov hauv qab no:
1. Silicate refractories: xws li quartz xuab zeb, quartz cib, mullite, bauxite, thiab lwm yam. Cov ntaub ntawv no muaj zoo heev kub tsis kam thiab tshuaj stability thiab yog dav siv nyob rau hauv kub kub furnaces thiab refractory linings.

2. Alumina refractories: xws li alumina cib, alumina ceramic fibers, thiab lwm yam. Alumina muaj qhov siab melting point, siab hardness thiab zoo heev hnav tsis kam, thiab yog dav siv nyob rau hauv refractory furnaces, refractory linings thiab refractory coatings.

3. Silicon carbide refractories: xws li silicon carbide cib, silicon carbide ceramic fibers, thiab lwm yam. Silicon carbide muaj zoo heev kub tsis kam, kub poob siab kuj thiab tshuaj stability, thiab yog dav siv nyob rau hauv kub kub rauv thiab refractory hauv ob sab phlu.

4. High aluminium refractory cov ntaub ntawv: xws li siab aluminium cib, siab aluminium ceramic fiber ntau, thiab lwm yam. Cov khoom siv aluminium siab muaj cov yam ntxwv ntawm qhov kub thiab txias thiab zoo hnav tsis kam, thiab feem ntau siv hauv metallurgy thiab kev tsim kho.

5. Silicon-carbon refractories: xws li silicon-carbon cib, silicon-carbon ceramic fibers, thiab lwm yam. Silicon carbon cov ntaub ntawv muaj zoo heev kub tsis kam thiab thermal shock kuj, thiab yog dav siv nyob rau hauv kub kub kho hlau thiab refractory hauv ob sab phlu.

Feem ntau, refractories yog ib chav kawm ntawm cov ntaub ntawv uas muaj peev xwm tswj tau cov txheej txheem thiab kev ua tau zoo stability nyob rau hauv qhov kub thiab txias ib puag ncig, nrog zoo heev kub kuj thiab thermal shock kuj. Cov refractories sib txawv ua lub luag haujlwm tseem ceeb hauv kev lag luam sib txawv, muab kev tiv thaiv kev ruaj ntseg thiab kev txhawb nqa rau cov txheej txheem kub.
