摘要： The invention relates to a gas torch nozzle, comprising a nozzle body with axial gas supply channels. According to the invention, there is provided an outlet ring (115) mounted on the distal end of the nozzle body (101), said ring having a large number of small axial holes (117) forming outlet orifices, and a traversing element (120) made of porous metal, for example sintered metal, is arranged between the downstream end of the supply channels (103) and the above mentioned outlet ring (115), said element letting the gas pass through said axial holes during normal operation of the torch in order to obtain a flame fractionated into small tongues, but stopping the propagation of the flame upstream when igniting said torch. Preferably, the number and the cross-section of said axial holes (117) are selected to that the outlet ring (115) acts also as a noise limiter.

摘要： The invention concerns a method and a device for acetylene cutting of continuous cast billets, which consists in positioning relative to the billets to be cut (1) a cutting element (8) and a trimming element (9) using a direct reference hold on the billet (1) by means of a mobile clamp (7), then lowering the cutting element (8) and the trimming element (9) parallel to the lateral surfaces of the billet so as to gradually produce a cut from above downwards by a horizontal engagement of the lateral surface of the billet, and simultaneous trimming of the cutting line being formed on the other lateral surface by an engagement of said other lateral surface constantly directed downwards.

摘要： Gas burner (30) consisting of at least two concentric rings (33, 34) individually gas-fed and each having gas ejection outlets for structuring the burner flame into a plurality of concentric flames. The outer ring (33) gas ejection outlets are also designed to produce a regular gas flow, so that the corresponding flame forms a sonic curtain for the turbulence of the flame formed on the ring or on the inner rings (34).

摘要： The invention concerns an installation (1) for continuously monitoring ferrous products derived from casting, comprising a controlled gas torch (20) transversely mobile to the ferrous product (B), said gas torch including a visual inspection device enabling direct observation of a zone of the surface in the sampling bath. The invention is characterised in that it further comprises a device for analysing images and identifying defects appearing in the field of vision of the visual inspection device. Said monitoring installation can be adapted on oxyacetylene cutting plants so as to make the oxyacetylene cutting completely automatic. It can be followed by a scarfing installation automatically cutting along the detected defects.
