Abstract:
An indirect radiant heating device that bums gaseous or liquid fossil fuel for the heat treatment of running metal products, the device comprising:a radiant cassette of parallelepipedal shape, with a continuous radiating surface whose cross section, in a plane perpendicular to the axis of the cassette, is defined by a continuous line which falls inside a rectangle whose height/width ratio is greater than 1.5; a combustion tunnel located inside the radiant cassette; a burner positioned inside the cassette and having at least two fossil fuel injectors arranged parallel to a plane of a main face of the cassette so as to spread the flame parallel to the said face, producing a uniform distribution of the flame temperature parallel to the said plane; a heat recuperator mounted between at least two faces of the cassette and over part of a length of the faces for heating fuel or oxidizer supplied to the device.
