Metallographic Structure ye enamel pane cast iron

Enamel-yakavharidzirwa cast iron cookware inogadzirwa kubva kune chaiyo kuumbwa kweakakanda simbi zvikamu, kusanganisira ferrite uye pearlite. Ferrite chikamu chakapfava uye chinochinjika, nepo pearlite ichibatanidza ferrite uye simenti, ichichipa simba nekuoma.

Mukuita kwekushandisa enamel coating kukanda simbi, zvakakosha kuti unzwisise iyo metallographic chimiro kuti uve nechokwadi chekunamira uye kusimba. Iyi blog positi ichaongorora iyo metallographic chimiro chesimbi yakakandwa, yakanyatso kutarisisa pamatanho anobatsira mukubudirira kwekushandiswa kweenamel coating.

1. Base Layer: Grey Cast Iron
Iyo yepasi layer yesimbi yakakandwa inoshandiswa pakunamira enamel inowanzoita grey cast iron. Iri rudzi rwesimbi yakakandwa inozivikanwa nekukwira kwayo kabhoni yemukati, iyo inoipa simba rakanakisa uye kusamira kupfeka. Iyo inoratidzirwawo neiyo graphite flakes, iyo inopa yakanaka yekupisa conductivity uye kuderedza brittleness.
2. Substrate Kugadzirira: Sandblasting uye Kuchenesa
Iyo yakakandwa simbi yepamusoro inofanirwa kugadzirirwa kufambisa kwakaringana kunamatira kweiyo enamel coating. Izvi zvinowanzobatanidza kuputika kwejecha kubvisa chero tsvina kana tsvina, inoteverwa nekunyatsocheneswa kuti ive nechokwadi chenzvimbo yakachena, yakatsetseka kuitira kuti enamel inamate.
Nekuputira enamel, simbi yakakandwa inofanira kuva nechiyero chekuenzanisa cheferrite uye pearlite. Ichi chinyorwa chinopa hwaro hwakasimba hwekuti enamel ibatire uye inovimbisa kusimba kwekupfeka. Chikamu cheferrite chinobatsira mukutora uye kugovera kupisa zvakaenzana, nepo pearlite chikamu chinowedzera simba uye kuramba kupfeka.

Pamusoro peferrite uye pearlite, zvimwe zvinhu zvakaita sekabhoni, silicon, uye manganese zvinoita basa rakakosha. Carbon content inofanira kuva pakati nepakati kuti ipe simba uye kudzivirira brittleness. Silicon inobatsira mukunamira kweiyo enamel coating, nepo manganese ichiwedzera simba rose uye kuoma kwesimbi yakakandwa.
Kupfupisa, iyo yakanakira kuumbwa kweenamel-yakavharwa cast iron cookware inosanganisira yakaenzana reshiyo yeferrite uye pearlite, ine mwero kabhoni yemukati, uye kuvapo kwesilicon uye manganese. Ichi chinyorwa chinovimbisa kugadzika kweenamel, kunyange kugovera kupisa, uye kushanda kwenguva refu kwekubika
