Claims (7)

1. Sulatusuuni raaka-aineen sulattamiseksi mineraalikuitu-valmistuksen yhteydessä, jonka uunin sivuseinämät kannattavat tulenkestävän, mahdollisesti useampikerroksisen vuorauksen, joka sisältää eri lämmönjohtokyvyn omaavia materiaaleja, tunnettu siitä, että vuoraus sisältää ainakin yhden kerroksen (14) jossa on sivuseinämän korkeus-suunnassa rajoitettu, sulapinnan (7) ja/tai sulan (6) ja pohjaraudan (8) rajapinnan korkeudella oleva vyöhyke (14') joka on materiaalia, jonka lämmönjohtokyky on suurempi kuin kerroksessa muutoin (14") käytetyn materiaalin.
2. Patenttivaatimuksen 1 mukainen sulatusuuni, tunnet-t u siitä, että lämmönjohtokyky vyöhykkeessä (14') on 2 -5 kertaa suurempi kuin lämmönjohtokyky muutoin kerroksessa.
3. Jonkin edellisistä patenttivaatimuksista mukainen sulatusuuni, tunnettu siitä, että vyöhyke (14’) muodostuu grafiitti-, SiC- tai C-SiC-massasta tai -tilleistä.
4. Patenttivaatimuksen 3 mukainen sulatusuuni, tunnettu siitä, että kerros (14) muutoin on Al203-, MgO-, Mg0/Cr203- tai Al203/Cr203-poh jäistä materiaalia olevaa massaa tai tiilejä.
5. Jonkin patenttivaatimuksista 1-4 mukainen sulatusuuni, tunnettu siitä, että sanottu kerros muodostaa välikerroksen, joka sulaa kohti kannattaa varsinaisen uunivuorauksen (15) muodostavan kerroksen.
6. Patenttivaatimuksen 5 mukainen sulatusuuni, tunnettu siitä, että uunivuoraus (15) muodostuu Al203/Cr203-pohjaisesta materiaalista.
