Description
Предлагаемое изобретение состоит в том, что дл пайки твердым припоем по методу погружени издели в припой применена электрическа сопротивлени , при конструировании которой использован принцип электрической сол ной ванны.The present invention consists in that for brazing by the method of immersing the product in the solder, electrical resistance is applied, in the design of which the principle of an electric salt bath is used.
На прилагаемом чертеже фиг. 1-3 изображают электрическую печь в трех проекци х.In the attached drawing of FIG. 1-3 depict an electric oven in three projections.
В огнеупорную кладку 7 заделаны два боковых графитовых или железных электрода 2 и один подовый графитовый электрод 3. В плавильном пространстве вверху расположен слой буры 4 и внизу слои твердого припо 5, например, сплав меди с цинком.Two side graphite or iron electrodes 2 and one bottom graphite electrode 3 are embedded in the refractory masonry 7. In the melting space at the top there is a layer of borax 4 and at the bottom layers of solid solder 5, for example, copper-zinc alloy.
Пайка производитс следующим образом: части, подлежащие пайке, погружаютс в слой расплавленной буры, где освобождаютс от окислов-и разогреваютс , после чего погружаютс глубже в расплавленный припой.Soldering is carried out as follows: the parts to be soldered are immersed in a layer of molten borax, where they are freed from oxides and heated, after which they are immersed deeper into the molten solder.
Принцип действи и пуск печи таковы же, как и дл существующих электрических сол ных ванн. Припой плавитс от тепла расплавленной буры и подогреваетс подовым электродом 3.The operating principle and start-up of the furnace are the same as for existing electric salt baths. The solder melts from the heat of the molten borax and is heated by the bottom electrode 3.
Дл данной печи необходим ступенчатый трансформатор. Печь может работать как трехфазным током, так и однофазным . При работе трехфазным током три провода присоедин ютс к трем электродам печи; при работе однофазным током, при пуске печи, два провода подвод тс к двум боковым электродам; после же расплавлени буры можно переключить ток таким образом, что один провод подводитс к двум боковым электродам, а другой-к подовому электроду .A step transformer is required for this furnace. The furnace can operate as a three-phase current and single-phase. In three-phase operation, the three wires are connected to the three electrodes of the furnace; when operating as a single-phase current; when the furnace is started up, two wires are supplied to the two side electrodes; after melting the borax, the current can be switched in such a way that one wire goes to the two side electrodes and the other to the bottom electrode.
