CONTINUOUS SMELTING FURNACE FOR QUARTZ RODS

Provided is a continuous smelting furnace for quartz rods, comprising a furnace body (1), an air inlet (2), and an air outlet (3), wherein an air guiding disk (4) is mounted at the air inlet (2), and the air guiding disk (4) comprises a plurality of air guiding holes (41). The air guiding holes (41) comprise a diffusion inclined angle and a swirl inclined angle, such that a protective gas enters the furnace body to generate diffusion and swirl effects, and such that the protective gas acts uniformly on a liquid quartz, avoiding the problems of inadequate action of the protective gas on the liquid quartz and over-reduction, and thereby reducing the problem of colour core on the quartz rods. L'invention concerne un four de fusion continu pour baguettes de quartz, comprenant un corps de four (1), une entrée d'air (2) et une sortie d'air (3), un disque de guidage de l'air (4) étant monté au niveau de l'entrée d'air (2) et le disque de guidage de l'air (4) comprenant une pluralité de trous de guidage de l'air (41)
