摘要
The invention relates to a device for igniting an aluminothermic composition, characterized in that it comprises an electric resistor for connecting two electrodes and to be supplied by an electric current source of in order to generate heat by a Joule effect, said electric resistor being exposed to a medium comprising oxygen and carbon so that the temperature rise of the medium by the resistor results in the formation of carbon monoxide, and then in an exothermal reaction of the latter with oxygen, thus generating a flame capable of igniting of the aluminothermic composition.
