Claims (2)

1. Способ индукционно-металлургической наплавки, преимущественно для односторонней непрерывно-последовательной наплавки внешним полем, включающий нанесение шихты на изделие, перемещение его относительно индуктора, пассивная ветвь которого осуществляет предварительный нагрев изделия, а основной нагрев до расплавления шихты производят под активным витком, отличающийся тем, что пассивную и активную ветви индуктора устанавливают над наплавляемым изделием на разную величину зазора, пассивную ветвь располагают на величину насыпаемой шихты, а активную ветвь индуктора размещают на толщину наплавляемого слоя, при этом интенсивность нагрева под каждой ветвью индуктора соответствует зависимости
Figure 00000001

где Ji - интенсивность нагрева металла под ветвью индуктора, град/с;
J(I) - интенсивность нагрева под ветвью индуктора при зазоре, равном 1 мм, град/с;
Δ1,4-1,5 - зазор между ветвью индуктора и основным металлом изделия, мм.1. The method of induction-metallurgical surfacing, mainly for one-sided continuous-sequential surfacing by an external field, including applying the charge on the product, moving it relative to the inductor, the passive branch of which preheats the product, and the main heating to melt the charge is produced that the passive and active branches of the inductor set over the deposited product at a different gap, the passive branch is placed on the amount of sheaf you, as an active inductor branch is placed on the thickness of the deposited layer, the heating rate at each branch of the inductor corresponds to the dependence
Figure 00000001

where J i - the intensity of heating of the metal under the branch of the inductor, deg / s;
J (I) is the intensity of heating under the inductor branch with a gap equal to 1 mm, deg / s;
Δ 1.4-1.5 - the gap between the branch of the inductor and the base metal of the product, mm. 2. Способ индукционно-металлургической наплавки по п. 1, отличающийся тем, что ветви индуктора под воздействием электромагнитного поля токов высокой частоты создают в поверхностном слое изделия наводящие токи, направленность которых такая же, как и в валике расплавленной шихты, причем токи способствуют металлургическому процессу перемешивания жидкого металла в сварочно-наплавочной ванне, улучшая при этом раскисление и обеспечивая стабильность состава металла по всему объему. 2. The method of induction-metallurgical welding according to claim 1, characterized in that the inductor branches under the influence of the electromagnetic field of high-frequency currents create in the surface layer of the product inductive currents, the direction of which is the same as in the molten charge roller, and the currents contribute to the metallurgical process mixing of the molten metal in the weld surfacing bath, while improving deoxidation and ensuring the stability of the metal composition throughout the volume.
