Изобретение относитс  к электротермии, в частности к электроиио-лучевой обработке материалов .FIELD OF THE INVENTION The invention relates to electrothermal, in particular, electro-ray-beam material processing.

Известны способы электронно-лучевого оплавлени  слитков, осуществл ющие проплавление поверхности слитка электронным пучком и одновременное перемещивание ванны расплава электромагнитным полем от индуктора .Methods are known for electron beam melting of ingots, which carry out the melting of the surface of the ingot by an electron beam and the simultaneous displacement of the molten bath by an electromagnetic field from the inductor.

Недостатком известных способов  вл етс  то, что электромагнитное поле индуктора преп тствует прохождению электронного пучка и мещает управлению пучком на поверхности оплавл емого металла.A disadvantage of the known methods is that the electromagnetic field of the inductor prevents the passage of the electron beam and displaces the control of the beam on the surface of the melted metal.

По предлагаемому способу с целью устранени  указанного недостатка оплавление и перемешивание осуществл ют попеременно путем коммутации напр жений, подаваемых к пущке электронного пучка и к индуктору.In the proposed method, in order to eliminate this drawback, reflowing and mixing are carried out alternately by switching voltages applied to the electron beam trigger and to the inductor.

Врем  включени  пушки может быть не равно (а больше) времени работы индуктора , причем частота переключений подбираетс  экспериментально с тем, чтобы поддерживались необходима  температура расплавл емой зоны и необходима  глубина перемешивани  ванны расплава.The switch-on time of the gun may not be equal to (and longer) the time of operation of the inductor, and the switching frequency is chosen experimentally so that the required temperature of the molten zone is maintained and the depth of the melt bath is necessary.

Предмет изобретени Subject invention

Способ электронно-лучевого оплавлени  поверхности слитков электронным пучком с перемешиванием ванны расплава электромагнитным полем от индуктора, отличающийс  тем, что, с целью устранени  вли ни  магнитного пол  индуктора на прохождение электронного пучка, оплавление и перемещивание осуществл ют попеременно путем коммутации напр жений, подаваемых к пушке электронного пучка и к индуктору.The method of electron beam melting of the surface of ingots by an electron beam with mixing of the molten bath by an electromagnetic field from an inductor, characterized in that, in order to eliminate the influence of the magnetic field of the inductor on the passage of the electron beam, melting and displacement are carried out alternately by switching voltages applied to the gun electron beam and to the inductor.
