Claims (4)

1. Sulatusuuni erityisesti kevytmetallia varten, joka käsittää pitkänomaisen kammion (4, 7, 11, 12) tulenkestävästä materiaalista, jossa on tuloaukko romulle (18) ja/tai 5 harkoille (5) sen toisessa päässä tai tämän läheisyydessä, kuonan poisto (5, 6) ainakin sen toisessa sivussa, poisto-ränni (13) annosteluaukolla (14) sen toisessa päässä sekä lämpöelementtejä metallin sulattamiseksi käsittäen suora-säteileviä vastuselementtejä (3, 3') kammion (4, 11, 12) 10 kannessa sekä pystysuunnassa vapaasti liikkuvia, alaspäin suunnattuja uppoelementtejä (8, 9), jotka on tarkoitettu kellumaan kammiossa (7) olevassa sulassa metallissa, tunnettu siitä, että rännin (13) korkeus on suurin piirtein 1/3 - 2/3 kammion (7, 12) korkeudesta ja että uppoelement-15 tien aktiivinen osa (8) korkeussuunnassa on korkeintaan yhtä kuin rännin (13) pohjan (16) etäisyys kammion pohjasta (17).
2. Patenttivaatimuksen 1 mukainen sulatusuuni, tunnettu 20 kammion (7, 12) pohjasta (17) ylöspäin suunnatusta kynnys- seinämästä (15) uppoelementtien (8, 9) ja rännin (13) välillä ja jonka dimensio korkeussuunnassa on pienempi kuin rännin pohjan (16) ja kammion pohjan (17) välinen etäisyys.
3. Patenttivaatimuksen 1 tai 2 mukainen sulatusuuni, tunnettu yhdestä ja kahdesta kammion (4, 7) pituussuunnassa välimatkan päässä olevista, sen kannesta alaspäin suunnatusta esirippuseinämästä (10) tuloaukon (18) ja uppoelementtien (8, 9) välillä ja jotka ulottuvat tasolle, joka 30 on alempana kuin rännin pohja (16) ja edullisesti samalle tasolle kynnysseinämän (15) yläreunan kanssa.
4. Jonkin edellisen patenttivaatimuksen mukainen sulatusuuni, tunnettu siitä, että annosteluaukko on alaspäin 35 suunnattu ja varustettu sama-akselisella karalla, jonka toisessa päässä on kartio, joka tiiviisti liittyy vastaavasti kartiomaiseen, alaspäin suunnattuun aukkoon annostelu-aukon ylemmässä tulopäässä.
