Yaya ake yin nada na induction dumama tanderun?

Kafin karkatar da coil na shigowa dumama tanderu, tsantsar bututun jan karfe yana gogewa. Ci gaba da tsabtataccen bututun jan ƙarfe a 650-700 ℃ don 30-40min, sannan a kwantar da shi da sauri a cikin 20-30%: ruwa. Kayan aikin dumama ya fi dacewa da tanderun juriya.

(1) Iska. An raunata bututun jan ƙarfe mai tsafta a cikin murɗar tanderun dumama. Yi amfani da ƙarfe ko ƙirar itace lokacin da ake juyawa. Idan akai la’akari da bututun jan ƙarfe bayan jujjuyawa, girman ƙirar ya kamata ya zama ƙasa kaɗan fiye da girman da ake buƙata. Lokacin da radius yana da ƙananan, ya kamata a gudanar da iska mai zafi, wato, bututun jan karfe mai tsabta a sashin lanƙwasa ya kamata a gasa tare da harshen wuta a cikin iska.

(2) Gyara. Gyara murhun murhun murɗawar rauni zuwa girman da ake buƙata kuma danna shi tare da matsi.

(3) Ragewa. The nada annealing zafin jiki, lokaci da kuma hanyar shigowa dumama tanderu daidai suke da na tsantsar bututun jan ƙarfe.

(4) Gwajin Hydrostatic. Wuce ruwa ko iska tare da matsa lamba 1.5 na ƙirƙira matsi na ruwan ciyarwa cikin tsantsar bututun jan ƙarfe na coil na induction dumama tanderun, kuma duba ko akwai wani ɗigon ruwa a haɗin gwiwa tsakanin bututun jan karfe da bututun.

(5) Mai rufe fuska. Matsa kintinkirin gilashin da ba shi da alkali akan bututun jan ƙarfe zalla.

(6)Dp insulating varnish. Yi preheat ɗin murhu na induction dumama tanderun da aka lulluɓe da Layer mai rufewa a cikin tanderun juriya ko akwatin bushewar iska mai zafi, sannan a nutsar da shi a cikin varnish mai hana ruwa na tsawon mintuna 15. Idan akwai kumfa da yawa a cikin fenti yayin aikin tsomawa, ya kamata a tsawaita lokacin tsomawa, gabaɗaya sau uku.

(7) bushewa. Ana yin shi a cikin tanderun juriya ko akwatin bushewar iska mai zafi. Lokacin da aka shigar da coil na induction dumama tanderun, zafin tander bai kamata ya zama sama da 50 ° C ba, kuma zafin zafin ya kamata a ɗaga shi a cikin ƙimar 15 ° C / h, kuma a bushe shi tsawon sa’o’i 20 a 100- 110 ° C, amma ya kamata a gasa har sai fim din fenti bai tsaya a hannun ba. A ƙarshe, da shirye permeable maganadisu da nada na shigowa dumama tanderu an tattara su cikin cikakken inductor.
