1. Chrome tsaw ai magri mang ni a hkrang sumla ni
Chrome cast iron gaw chromium grau law ai cast iron re. Chromium hpe jat bang ai majaw, chromium law ai iron gaw grai kaja ai n-gun hpe ninghkap lu ai atsam, n-gun n-gun hpe ninghkap lu ai atsam hte nbung katsi ai lam grai law ai, jak rung ni hpe galaw shapraw ai, hka pump galaw ai, lung seng htu ai jak hte kaga field ni hta grai lang ai.
2. Chromium cast iron a matu katsi ai tsi ladat
Chromium cast iron law ai hpe katsi ai tsi ladat a matu, n bung ai ladat ni rai nga ai, aten tup wan hkru ai, n-gun rawng ai hte n-gun rawng ai lam ni hpe jai lang ai gaw, dai arai a ngang kang ai hte n-gun hpe grau kaja hkra galaw na matu rai nga ai.
1. Wan rai nga ai
Kaja ai tsi lajang ai ladat hpe jai lang nna, chromium cast iron law ai hpe 500 daram n-gun ja ai hku bai jat nna, dai arai a htum mat ai lam hpe lu la na matu, n-gun kaba ai. Orthofified gaw high-chromium cast iron a n-gun atsam hte ngang kang ai lam hpe shatsaw ya lu ai, raitim, dai arung arai ni a n-gun yawm wa shangun ai.
2. Wan hkru ai
Quenching ngu ai gaw, n-gun ja ai chromium cast iron hpe, n-gun ja ai hte n-gun ja ai hpe lu la na matu, tank langai hta tsi lajang ai lam re. 800 hte 980℃lapran hta n-gun rawng ai nbung laru gaw, n-gun n-gun hpe koi gam na matu grai lawan ai hku koi ra ai.
3. myit ja ai
Tempering galaw ngut ai hpang, chromium cast iron hpe n-gun ja ai hku bai tsi lajang ya nna, dai arung arai a n-gun hpe shayawm ya lu nna, shi a ngang kang ai hte ductility hpe grau kaja hkra galaw ya lu ai. Tempering tsi lajang ai lam a general temperature gaw 280 ~ 520℃rai nna, aten gaw hkying hkum 1 ~ daram rai nga ai.
3. Chromium cast iron ntsa hta n bung ai nbung hpe tsi lajang ai ladat ni a akyu .
N bung ai katsi ai hpe tsi lajang ai ladat ni a majaw byin pru wa ai n bung ai katsi ai hpe tsi lajang ai ladat ni. Chromium law ai majaw, chromium cast iron grai law ai majaw, tsi lajang ai lam hta chromization byin chye ai, dai gaw dai arai a bungli galaw ai lam hpe hkra machyi shangun ai. Dai majaw, katsi ai hpe tsi lajang ai lam garai n galaw shi yang, chroroization a n-gun hpe n-gun n-gun n-rawng hkra, htap htuk ai tsi lajang ai lam hte aten hpe lata la ra ai.
Normal heat treatment gaw dai arung arai a ngang kang ai lam hte n-gun hpe shatsaw ya lu ai, raitim, shi a ngang kang ai hte ductility, n-gun n rawng ai hte kaga manghkang ni hpe mung hkra machyi shangun na re. Quenching tsi lajang ai gaw, dai arung arai a ngang kang ai lam hte n-gun hpe shatsaw ya lu nna, shi a grai kaja ai n-gun hpe ninghkap lu ai atsam hte n-gun n-gun hpe n-gun jaw lu ai; hte tempering tsi lajang ngut ai hpang, dai arung arai a ngang kang ai lam yawm mat ai, ngang kang ai hte ductility hpe shatsaw ya ai, raitim, dai arung arai a n-gun hpe ninghkap lu ai atsam hte n-gun n-gun hpe shayawm ya lu ai.
4. yawng sum
Chromium cast iron a arawn alai ni gaw, katsi ai hpe tsi lajang ai shaloi, chromamophenomenon byin pru wa ai hpe myit maju jung ra ai, hte htap htuk ai katsi ai tsi ladat hpe lata ra ai. N bung ai tsi ladat ni rai nga ai, aten tup wan hkru ai, htum mat ai hte n-gun ja ai lam ni gaw, n-gun ja ai, ngang kang ai, ductility, n-gun n-gun hpe hkam sharang lu ai atsam hte n-gun n-gun hpe ninghkap lu ai atsam hpe dawdan ya ai. Dai hpe jai lang ai lam hta, n-gun ja ai n-gun rawng ai arung arai ni hpe grai kaja hkra galaw lu na matu, laksan jai lang ai lam ni hte maren, htuk manu ai katsi ai tsi ladat ni hpe lata ra ai.
