Mechanical Properties na bakin karfe faranti, aiki effects
(1) Carbon;Mafi girman abun ciki na carbon, ƙarfin ƙarfe, amma ƙarancin filastik da ductile shine.
(2) Sulfur;Shin tarkace mai cutarwa ne a cikin ƙarfe, ƙarfe tare da sulfur mafi girma a cikin sarrafa matsa lamba mai ƙarfi, mai sauƙin fashe, yawanci ana kiransa zafi brittleness.
(3) Phosphorus;Yana iya rage yawan filastik da taurin karfe, musamman ma a yanayin zafi mara nauyi, wanda ya fi muni, kuma ana kiran wannan al'amari sanyi brittleness.A cikin ƙarfe mai inganci, sulfur da phosphorus yakamata a sarrafa su sosai.Amma a daya hannun, low carbon karfe ƙunshi mafi girma sulfur da phosphorus, zai iya sa ta yanke sauki karya, don inganta machinability na karfe ne m.
(4) Manganese;Zai iya inganta ƙarfin ƙarfe, zai iya raunana da kuma kawar da mummunan tasirin sulfur, kuma zai iya inganta ƙarfin ƙarfe, babban ƙarfe mai ƙarfi tare da babban abun ciki na manganese (babban ƙarfe na manganese) yana da juriya mai kyau da sauran kayan jiki.
(5) Siliki;Yana iya inganta taurin karfe, amma filastik da rashin ƙarfi, ƙarfe na lantarki ya ƙunshi wani adadin silicon, zai iya inganta halayen magnetic mai laushi.
(6) Tungsten;Zai iya inganta taurin ja, ƙarfin zafi da juriya na ƙarfe.
(7) Chromium;Yana iya inganta hardenability da sa juriya na karfe, inganta lalata juriya da hadawan abu da iskar shaka juriya na karfe.
(8) Zinc;Domin inganta juriya na lalata, babban bututun ƙarfe (baƙar fata) yana galvanized.Galvanized karfe bututu ya kasu kashi biyu na zafi tsoma galvanized karfe da lantarki karfe zinc, zafi galvanized galvanized Layer kauri, lantarki galvanized kudin ne low, don haka akwai galvanized karfe bututu.
Mechanical Properties da hanyoyin tsaftacewa na bakin karfe faranti
1. na farko da amfani da sauran ƙarfi tsaftacewa karfe surface, surface na kwayoyin halitta kau,
2. sannan a yi amfani da kayan aiki don cire tsatsa (buroshin waya), cire sako-sako ko karkatar da sikelin, tsatsa, slag walda, da sauransu.
