Menene yanayin ƙirƙira na wani injin wuta?

1. Farkon ƙirƙira zafin jiki na induction dumama tanderun:

Lokacin da zafin ƙirƙira na farko na induction dumama tanderun yana da girma, nakasar filastik na kayan ƙarfe yana da girma, juriya kaɗan ne, ƙarfin motsa jiki da ake cinyewa yayin nakasawa kaɗan ne, kuma ana iya amfani da fasahar sarrafawa tare da adadin nakasawa mai girma. Koyaya, zafin zafi na induction dumama tanderun yana da yawa, wanda ba wai kawai yana haifar da iskar oxygen mai tsanani da haɓakar carbon ba, har ma yana haifar da yawan zafin jiki da kuma ƙonewa. Lokacin da aka ƙayyade farkon ƙirƙira zafin jiki na induction dumama tanderun, abu na farko da za a yi shi ne don tabbatar da cewa kayan ƙarfe ba su haifar da zafin jiki da ƙonewa ba, kuma wani lokacin ana iyakance shi ta hanyar narkar da yanayin zafi mai ƙarfi. Don karfen carbon, don hana zafi fiye da kima, zafin zafi na farawa da ƙarewa yawanci 130-350 ° C ƙasa da layin ƙarfi na zane-zane na ƙarfe-carbon lokaci.

Hakanan dole ne a daidaita zafin ƙirƙira na farko na tanderun dumama induction daidai gwargwadon takamaiman yanayi. Lokacin da aka yi amfani da ƙirƙirar guduma mai saurin gaske, yanayin zafin zafin da ke haifar da nakasar mai saurin na iya sa billet ɗin ya ƙone sosai. A wannan lokacin, zafin jiki na farko ya kamata ya zama mafi girma fiye da Gabaɗaya, zafin ƙirƙira na farko shine kusan 150 ° C ƙasa.

2. Ƙarshe na ƙirƙira zazzabi na induction dumama tanderun:

Matsakaicin ƙirƙira na ƙarshe na induction dumama tanderun ya yi yawa. Bayan an dakatar da ƙirƙira, kristal na ciki na ƙirƙira zai sake girma, kuma tsarin ƙwayar ƙwayar ƙwayar cuta zai bayyana ko lokacin na biyu zai narke, yana rage abubuwan da ke cikin ƙirƙira. Idan zafin ƙirƙira na ƙarshe na tanderun dumama shigarwa ya yi ƙasa da zafin zafin aiki, ƙarfin aikin sanyi zai faru a cikin billet ɗin ƙirƙira, wanda zai rage nakasar filastik kuma yana haɓaka juriyar nakasar. Akwai babban damuwa na ciki, wanda ke haifar da ƙirƙira don fashe yayin duk aikin sanyaya ruwa ko tsarin abin da ya faru. A gefe guda, rashin cikar haɓakar thermal kuma zai haifar da hanyoyin ƙirƙira asymmetrical. Don tabbatar da aikin taurin aikin a cikin ƙirƙira bayan ƙirƙira, ƙimar ƙirƙira ta ƙarshe na tanderun dumama induction yawanci shine 60-150 ° C sama da zafin ƙarfin aikin ƙarfe. Ana amfani da juriya na nakasar kayan ƙarfe galibi azaman maɓalli don tantance zafin ƙirƙira na ƙarshe na tanderun dumama.
