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： 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.
摘要翻译：本发明涉及一种气体喷枪喷嘴，其包括具有轴向气体供应通道的喷嘴主体。根据本发明，提供一种安装在喷嘴主体（101）的远端上的出口环（115），所述环具有形成出口孔的大量小轴向孔（117）以及横向元件（120 ）由多孔金属（例如烧结金属）制成，布置在供应通道（103）的下游端和上述出口环（115）之间，所述元件在气体正常操作期间使气体穿过所述轴向孔以获得分成小舌片的火焰，但是当点燃所述火炬时阻止火焰向上游传播。优选地，所述轴向孔（117）的数量和横截面被选择为使得出口环（115）也充当噪声限制器。

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 oxyacetylene cutting apparatus comprising a support element (10) produced from a stainless steel block which cannot be deformed, a heating element (20) permanently fixed against a bottom surface (19) of the support element (10), which heating element is produced from a massive copper block wherein are provided passages for gas fluids and the cooling fluid which communicate directly with the support element (10) corresponding conduits. At least one nozzle (30) is precisely positioned in two coaxial bores (31, 32) provided in the support element (10) and the heating element (20) respectively, the nozzle being connected to a conduit (14.6) supplying oxygen for cutting. A retaining element (40) is preferably used to enhance the precise positioning of the nozzle (30).
