Abstract

1. Большой режущий мундштук (1) для резки заготовок из стали и заготовок (200) из железных сплавов, в частности плит, слитков и сутунок, состоящий из корпуса (2) мундштука с резьбой (4) для крепления к газовому резаку (100), центрально расположенного канала (5) режущего кислорода, множества каналов (10) горючего газа, концентрично расположенных по конкретной внутренней окружности отверстий (10.1), и множества каналов (11) подогревающего кислорода, концентрично расположенных по следующей промежуточной окружности отверстий (11.1), причем выпускные отверстия пропускных каналов (5, 10, 11) выходят в зазор (7), огороженный корпусом (2) мундштука, отличающийся тем, что зазор (7), огороженный корпусом (2) мундштука, имеет угловую, коническую или приблизительно полукруглую форму, образованную выходными отверстиями пропускных каналов (5, 10, 11) для режущего кислорода, подогревающего кислорода и горючего газа, так что поступающие вещества перенаправляются по наклонным или кривым выходным поверхностям (F) к центру мундштука и закручиваются воздухом на большее расстояние (В) от большого режущего мундштука (1) вне корпуса (2) мундштука.2. Большой режущий мундштук по п.1, отличающийся тем, что выходные поверхности (F) пропускных каналов (5, 10, 11) располагаются в корпусе (2) мундштука и могут быть при необходимости объединены друг с другом.3. Большой режущий мундштук по п.1, отличающийся тем, что множество каналов кислорода (13) дополнительно проходит через корпус (2) мундштука и ведет к кольцевидной канавке (12) у выходного торца корпуса (2) мундштука с тем, чтобы дополнительно выходящий кислород образовывал трубообразную защитную кислородную перегородку (16).4. Большой1. Large cutting mouthpiece (1) for cutting billets of steel and billets (200) of iron alloys, in particular slabs, ingots and slabs, consisting of a die body (2) with a thread (4) for attaching to a gas cutter (100) , a centrally located channel (5) of cutting oxygen, a plurality of channels (10) of combustible gas, concentrically located along a specific inner circumference of the holes (10.1), and a plurality of channels (11) of heating oxygen, concentrically located along the next intermediate circle of the holes (11.1), and the outlet openings of the passage channels (5, 10, 11) go into the gap (7) enclosed by the mouthpiece body (2), characterized in that the gap (7) enclosed by the mouthpiece body (2) has an angular, conical or approximately semicircular shape, formed by the outlets of the passage channels (5, 10, 11) for cutting oxygen, heating oxygen and combustible gas, so that the incoming substances are redirected along inclined or curved outlets over (F) towards the center of the mouthpiece and twist the air a greater distance (B) from the large cutting mouthpiece (1) outside the body (2) of the mouthpiece. 2. Large cutting mouthpiece according to claim 1, characterized in that the outlet surfaces (F) of the passage channels (5, 10, 11) are located in the body (2) of the mouthpiece and can be combined with each other if necessary. A large cutting mouthpiece according to claim 1, characterized in that a plurality of oxygen channels (13) additionally pass through the mouthpiece body (2) and lead to an annular groove (12) at the outlet end of the mouthpiece body (2) so that the additional outgoing oxygen forms a tubular oxygen barrier (16) 4.

Claims

1. A large cutting mouthpiece (1) for cutting billets made of steel and billets (200) made of iron alloys, in particular plates, ingots and casing, consisting of a body (2) a mouthpiece with thread (4) for attachment to a gas torch (100) , a centrally located cutting oxygen channel (5), a plurality of combustible gas channels (10) concentrically arranged along a specific inner circumference of the holes (10.1), and a plurality of oxygen heating channels (11) concentrically arranged along the following intermediate circumference of the holes (11.1), outlet openings the discharge channels (5, 10, 11) extend into the gap (7) enclosed by the mouthpiece body (2), characterized in that the gap (7) enclosed by the mouthpiece body (2) has an angular, conical or approximately semicircular shape formed by the outlet openings of passage channels (5, 10, 11) for cutting oxygen, heating oxygen and combustible gas, so that the incoming substances are redirected along inclined or curved exit surfaces (F) to the center of the mouthpiece and are twisted with air at a greater distance (B) from the large cutting mouthpiece (1) outside of Pusa (2) of the mouthpiece.

2. A large cutting mouthpiece according to claim 1, characterized in that the output surfaces (F) of the passage channels (5, 10, 11) are located in the body (2) of the mouthpiece and can be combined with each other if necessary.

3. A large cutting mouthpiece according to claim 1, characterized in that the plurality of oxygen channels (13) additionally passes through the mouthpiece body (2) and leads to an annular groove (12) at the output end of the mouthpiece body (2) so that the outlet oxygen formed a tube-like protective oxygen septum (16).

4. A large cutting mouthpiece according to claim 3, characterized in that the annular groove (12) has a variable cross section, preferably semicircular or rectangular.
