Abstract
1. Способ вертикально-стационарного плазмотрона, включающий горение дуги на электроде, формирование плазменной струи за счет газа и концентрацию дуги в сопле и электромагнитном поле, обогревающей формируемый металл, отличающийся тем, что в этом плазмотроне защита сопла происходит за счет расплава восстановленного или недовосстановленного металла, стекаемого по нему с расходуемого электрода или подсыпаемого на сопло отдельно, а его толщина регулируется режимами плавления за счет переполюсовки тока на электроде, сопле и формируемом металле, при этом газ для плазмы образуется в зоне горения дуги над соплом за счет откачки вакуума через зону формирования слитка металла, находящуюся под соплом. ! 2. Способ по п.1, отличающийся тем, что вертикально-стационарный плазмотрон может работать по принципу косвенного, прямого и переменного действия, при этом электрод является анодом, на котором выделяется кислород и другие газы, а слиток металла катодом, где восстанавливается металл электрохимически, плазмохимически и металлотермически. ! 3. Способ по п.2, отличающийся тем, что для усиления тепловой мощности плазмы газ может нагнетаться в дуговой разряд дополнительно, для усиления восстановления металла из полости ниже сопла проводят глубокую откачку вакуума. ! 4. Устройство вакуумно-стационарного плазмотрона, включающее горение дуги на электроде и охлаждаемом поддоне, сжатие дуги в плазму, которая подогревает расплав, формируемый в охлаждаемом кристаллизаторе, отличающееся тем, что поддон в центральной части имеет отверстие, что переводит его в сопло, на которое может быть подключен минус или ноль, а вокруг него может б1. The method of a vertically stationary plasmatron, including the burning of an arc on an electrode, the formation of a plasma jet due to gas and the concentration of the arc in the nozzle and an electromagnetic field that heats the formed metal, characterized in that in this plasmatron the protection of the nozzle occurs due to the melt of the reduced or underreduced metal flowing down it from the consumable electrode or poured onto the nozzle separately, and its thickness is regulated by melting modes due to the polarity reversal of the current on the electrode, nozzle and the formed metal, while the gas for the plasma is formed in the arc burning zone above the nozzle due to vacuum pumping through the formation zone an ingot of metal under the nozzle. ! 2. The method according to claim 1, characterized in that the vertically stationary plasmatron can operate according to the principle of indirect, direct and alternating action, wherein the electrode is the anode on which oxygen and other gases are released, and the metal ingot is the cathode, where the metal is electrochemically reduced , plasma-chemically and metallothermically. ! 3. The method according to claim 2, characterized in that in order to increase the thermal power of the plasma, the gas can be additionally injected into the arc discharge; to enhance the recovery of the metal from the cavity below the nozzle, a deep vacuum is pumped out. ! 4. The device of a vacuum-stationary plasmatron, including the burning of the arc on the electrode and the cooled pan, the compression of the arc into plasma, which heats the melt formed in the cooled crystallizer, characterized in that the pan in the central part has a hole, which transfers it to the nozzle, to which minus or zero can be connected, and around it can be
