If the focus position of a condensing type halogen line heater is shifted, field heating which gave width can be performed.
And if many halogen line heaters are connected, heating of a large area will also be attained.
Required in absolute high power, although there is “cavernous heating method” as approach from another direction
In the rapid heating to carry out, the technique of field heating which is introduced here is a more effective means.
The direction which adopted the condensed type mirror can choose heating width freely rather than using a parallel light type (parabolic mirror), and the utilization efficiency of light becomes good.
(since a parabolic mirror is generally shallow and there are few rates which catch light)
Specification of standard type Halogen line heater “HLH-55W / f25 / L280 / H18 / 200v-5kw”
Mirror width 55mm
Focal length 25mm
Effective mirror length 280mm
HLH-55W has created a groove in the refractory brick by the heated and melted.
Since absorption of light will also become good if the groove begins to be made by irradiation, it becomes high temperature.
In this groove had reached 1500 ℃ or more .
