Ilana Metallographic fun enamel lori irin simẹnti



    Ohun-elo irin simẹnti ti a bo Enamel jẹ lati inu akojọpọ kan pato ti awọn ipele irin simẹnti, pẹlu ferrite ati pearlite. Ferrite jẹ alakoso rirọ ati rọ, lakoko ti pearlite darapọ ferrite ati cementite, fifun ni agbara ati lile.

    Ninu ilana ti lilo ibora enamel lati sọ irin, o ṣe pataki lati loye eto metallographic lati rii daju ifaramọ ati agbara to dara julọ. Ifiweranṣẹ bulọọgi yii yoo ṣawari ọna iṣelọpọ ti irin simẹnti, ni pataki ni idojukọ lori awọn ipele ti o ṣe alabapin si ohun elo aṣeyọri ti ibora enamel.

  1.       1. ipilẹ Layer: Grey Simẹnti Iron
    Ipele ipilẹ ti irin simẹnti ti a lo fun ibora enamel jẹ deede irin simẹnti grẹy. Iru irin simẹnti yii ni a mọ fun akoonu erogba giga rẹ, eyiti o fun ni agbara to dara julọ ati yiya resistance. O ti wa ni tun characterized nipasẹ awọn oniwe-lẹẹdi flakes, eyi ti o pese ti o dara gbona iba ina elekitiriki ati ki o din brittleness.
  2.       2. Igbaradi sobusitireti: Sandblasting ati Cleaning
        Ilẹ simẹnti gbọdọ wa ni ipese lati dẹrọ imudara to dara ti ibora enamel. Eyi nigbagbogbo pẹlu iyanrin lati yọ eyikeyi aimọ tabi idoti kuro, atẹle nipa mimọ ni kikun lati rii daju mimọ, oju didan fun enamel lati faramọ.

  3.     Fun ideri enamel, irin simẹnti yẹ ki o ni iwọn iwontunwonsi ti ferrite ati pearlite. Tiwqn yii n pese ipilẹ to lagbara fun enamel lati faramọ ati ṣe idaniloju agbara ti a bo. Ipele ferrite ṣe iranlọwọ ni gbigba ati pinpin ooru ni deede, lakoko ti ipele pearlite ṣe afikun agbara ati resistance lati wọ.

        Ni afikun si ferrite ati pearlite, awọn eroja miiran bii erogba, silikoni, ati manganese ṣe ipa pataki. Akoonu erogba yẹ ki o jẹ iwọntunwọnsi lati pese agbara ati dena brittleness. Silikoni ṣe iranlọwọ ni ifaramọ ti ibora enamel, lakoko ti manganese ṣe alekun agbara gbogbogbo ati lile ti irin simẹnti.

  5.     Lati ṣe akopọ, akopọ ti o dara julọ fun ohun-elo irin ti a fi sinu enamel pẹlu ipin iwọntunwọnsi ti ferrite ati pearlite, akoonu erogba iwọntunwọnsi, ati wiwa silikoni ati manganese. Tiwqn yii ṣe idaniloju ibora enamel ti o tọ, paapaa pinpin ooru, ati iṣẹ ṣiṣe pipẹ ti ohun elo ounjẹ
