Lub neej thiab nto decarburization ntawmkauv cevyog ib qho kev sib txuas meej, yog tias lub nraub qaum decarbonization, kauv lub zog thiab hnav tsis kam yuav txo qhov cuam tshuam ncaj qha rau ntawm kauv ntawm lub neej.Yog hais tias cov pa roj carbon txheej ntawm cov kauv steel yeeb nkab tsis huv, kauv txheej txheej hardness thiab hnav tsis kam yuav raug txo raws li, thiab cov txheej txheem hardening, vim tias qhov kev hloov pauv ntawm qhov ntim los ntawm cov txheej txheem ntawm lub workpiece tsim cov kab nrib pleb.
Yuav ua li cas tiv thaiv cov kauv ntawm decarbonization, ntawm no yog cov lus teb:
Kev daws qhov teeb meem ntawm decarbonization saum npoo, feem ntau yuav tsum tau kho rau cov txheej txheem kev kho cua sov, vim tias oxidation thiab decarbonization thiab kauv yog tib lub sijhawm, yog li nyob rau hauv cov txheej txheem ntawm kev kho cua sov, peb yuav tsum sim ua kom cov coils thiab huab cua sib cuag, Qhov no txhim kho lub decarburization tshwm sim.
Qhov tshwm sim ntawm kauv decarbonization media feem ntau yog cov pa oxygen, dej vapor thiab carbon dioxide thiab lwm yam oxidizing gases, thaum cov pa roj carbon monoxide thiab cov cua kub sib cuag tuaj yeem ua rau oxidation thiab decarbonization kauv, yog li ntawd, tswj lub cub tawg thiab carbon dioxide carbon monoxide piv kuj tseem ceeb heev.
Nyob rau hauv qhov tseeb, ntxiv rau cov kauv forging rauv tiv thaiv roj nitrogen yog zoo heev, nitrogen yuav dispel ib co ntawm cov oxidizing gas, txo cov kauv ntawm decarbonization tshwm sim.
