【摘要】：試驗(yàn)過(guò)程模擬武鋼CSP均熱爐的加熱條件,分別研究加熱溫度、保溫時(shí)間、爐內(nèi)氣氛對(duì)彈簧鋼50CrV4表面脫碳的影響規(guī)律。結(jié)果表明,50CrV4鋼脫碳厚度隨保溫時(shí)間的延長(zhǎng)而增加;保溫時(shí)間為30和60min,加熱溫度低于1050℃時(shí),脫碳層厚度隨溫度升高而增加,高于1050℃時(shí),脫碳層由于氧化加劇而減少,1050℃為脫碳敏感溫度;O_2+CO_2+H_2O+N_2混合氣氛比O_2+CO_2+N_2和H_2O+N_2降低脫碳層厚度更加明顯。結(jié)合氧化模型和菲克第二定律,建立并修正了脫碳計(jì)算模型,利用試驗(yàn)數(shù)據(jù)驗(yàn)證其可靠性。
[Abstract]:The effect of heating temperature, holding time and atmosphere on surface decarburization of spring steel 50CrV4 was studied. The results showed that the decarburization thickness of 50CrV4 steel increased with the increase of holding time. When the heating temperature is lower than 1050 鈩，
