Pali zambiri zofunika zotsatirazi zitsulo kwa kulemetsa kovuta.

(1) Mpweya wa carbon wachitsulo umatsimikiziridwa ndi momwe ntchito zimagwirira ntchito, zomwe zimatha kuchokera ku 0.15% mpaka 1.2%. Ichi ndiye chofunikira kwambiri ndipo zofunika pakuchitapo kanthu zitha kukwaniritsidwa ndi kutentha kwa induction.

(2) Chitsulocho chiyenera kukhala ndi chizolowezi chakuti njere za austenite sizovuta kukula. Nthawi zambiri, nthawi yotenthetsera induction imakhala yaifupi, ndipo mbewu sizovuta kukula, koma kutentha kumakhala kokwera kwambiri.

(3) Chitsulocho chiyenera kukhala ndi mawonekedwe abwino komanso ofanana momwe angathere. Chitsulocho chimatha kupeza mbewu zabwino za austenite ndi kutentha kovomerezeka kovomerezeka pakuwotcha, komwe kumakhala kofunikira kwambiri pakuwotcha kwa induction, chifukwa kutentha kwa induction kumakhala kovuta kwambiri kuwongolera kutentha kwabwino kuposa kutentha kwa ng’anjo, ndipo kutentha kwa ng’anjo ndikokwera kwambiri. apamwamba.

(4) Kwa chitsulo chowumitsira chowonjezera, ndi bwino kuwongolera kukula kwambewu mukalasi 5 mpaka 8.

(5) Zosankha za carbon. Pazigawo zina zofunika monga crankshafts, camshafts, ndi zina zotero, posankha magiredi achitsulo, zofunikira zowonjezera za carbon zomwe zasankhidwa nthawi zambiri zimayikidwa patsogolo. Chitsulo 0.42% ~ 0.50%) chimachepetsedwa kufika pa 0.05% (monga 0.42% ~ 0.47%), zomwe zingachepetse kusintha kwa kusintha kwa carbon pa ming’alu kapena kusintha kwakuya kosanjikiza.

1. Zofunika zakuya za decarburization wosanjikiza wa chitsulo chozizira chokoka. Chitsulo chozizira chikagwiritsidwa ntchito poumitsa, pali zofunikira pakuzama kwa gawo lonse la decarburization pamtunda. Nthawi zambiri, kuzama konse kwa decarburization kumbali zonse kumakhala kosakwana 1% ya m’mimba mwake kapena makulidwe a mbale yachitsulo. Kuuma kwa mpweya wa carbon-deplet layer pambuyo pa kuzimitsidwa kumakhala kotsika kwambiri, kotero chitsulo chozizira chiyenera kuchotsedwa pamtunda wa carbon-depleted layer isanayambe kuyesa kuuma kozimitsa.
