Abstract
A. Treatment installation more particularly comprising a zonal heating system for elongated products, such as bars, tubes or wires made from inorganic material. B. This installation is characterized in that it comprises at least one introduction and supporting device for the product to be treated, at least one extraction and supporting device for that treated product and at least one treatment device traversed by the product, whereby at least one of these treatment devices is an enclosure in which there is an ultra-high frequency electromagnetic field. C. The invention applies more particularly to drawing glass wires.
Claims7
Apparatus for heating a predetermined zone of an elongated product, comprising:
- means for introducing the elongated product to a predetermined zone of treatment;
- means for extracting the treated product from said predetermined zone of treatment;
- means at said predetermined zone defining a cavity resonator through which said elongated product passes along a longitudinal axis, said cavity resonator when supplied with ultrahigh frequency electromagnetic energy being operative to maintain stationary waves of a resonant mode at a fixed predetermined location occupied by said elongated product moving through said cavity resonator to obtain a concentration of said ultrahigh frequency energy in the elongated product within said zone;
- and
- means operative to supply ultrahigh frequency electromagnetic energy to said cavity resonator.
