Abenzi bomatshini bokucima amaza aphezulu chaza ngokufutshane inkqubo yokucoca intsimbi

1. Isihlomelo esipheleleyo

Inkqubo: Ukufudumeza ngaphezu kwe-Ac3 ukuya kwi-30-50°C → ugcino lobushushu → ukupholisa ukuya ngaphantsi kweedigri ezingama-500 ngesithando somlilo → ukupholisa umoya kwiqondo lobushushu begumbi.

Injongo: ukucoca iinkozo, ukwakheka okufanayo, ukuphucula iplastiki kunye nokuqina, ukuphelisa uxinzelelo lwangaphakathi, kunye nokuququzelela umatshini.

2. Ukwehliswa okungafaniyo

Inkqubo: ukufudumeza ngaphezulu kwe-Ac3 → ugcino lobushushu → ukupholisa ngokukhawuleza ukuya kwi-pearlite utshintsho lobushushu → ukuhlala kwe-isothermal → inguqu ukuya ku-P → ukupholisa umoya;

Njongo: Ibid. Kodwa ixesha lifutshane, kulula ukulawula, kunye ne-deoxidation kunye ne-decarburization encinci. (Ifanele i-alloy iron kunye neengxenye ezinkulu ze-carbon steel ezine-stable stable supercooled A).

3. Ukongezwa kokudibanisa ukuqhubela phambili

Umbono: Yinkqubo yokwenza i-spheroidizing cementite kwintsimbi.
