Wurin zama mai ɗaukar nauyi shine zafin zafi tare da injin ƙararrawa. Menene sakamakon?
Wurin da aka saki yana da zafin zafi tare da wani induction hardening inji. Menene sakamakon?
Kaya na wurin zama mai ɗaukar nauyi yawanci No. 45 ƙarfe, wanda dole ne ya tsayayya da babban gogayya yayin aiki. Sabili da haka, abubuwan da ake buƙata don samarwa da rayuwa suna da girman gaske, suna buƙatar samun babban taurin kai, juriya mai ƙarfi da tsawon rayuwar sabis. A saboda wannan dalili, masana’antun da yawa suna amfani da na’urori masu taurin ƙarfi don maganin zafi. A yau, zan gaya muku yadda sakamakon maganin zafi yake.
(1) Saurin saurin saurin dumamar yanayi na canje-canjen zafin jiki zai canza zafin mahimmin mahimmancin a cikin ƙarfe, wanda zai haɓaka layin Ac3. A ƙarƙashin yanayi na yau da kullun, yawan zafin wutar da ke ƙaruwa na No. 45 ƙarfe shine 890-930 ℃, kuma ana amfani da kashe ruwa da sanyaya mai. Lokacin da ake amfani da ruwan zagayawa a matsayin matsakaicin sanyaya, domin hana fasa, dole ne a rage zafin zafin dumamar. Ƙimar da aka ba da shawarar ita ce 820-860 ℃.
(2) Canjin lokacin dumama Lokacin da ake amfani da injin ƙarar mita mai ƙarfi don maganin zafi, ƙara ƙarfin fitarwa, rage lokacin dumama da girman gibin inductor, da zurfin Layer mai tauri wanda ya cika buƙatun fasaha na iya kuma a samu.
(3) Tsarin asali yana buƙatar dumama mai sauri-sauri don sanya abun da ke cikin austenite ba daidai ba, kuma tsarin asali yana da babban tasiri akan homogenization na austenite. Sabili da haka, dole ne a daidaita madaidaicin kujerar rabuwa kafin a kashe ƙwanƙwasawa don yin Tufafi da ingantaccen rarraba carbides zai taimaka homogenize austenite yayin dumama mai sauri, don haka guje wa fasa.
(4) Mai juyawa da yawa Za’a iya inganta ingancin dumama ta amfani da inductor mai juyawa da yawa.
