【摘要】：在實(shí)驗(yàn)室模擬現(xiàn)場(chǎng)加熱爐加熱過(guò)程,在CO_2、O_2、H_2O、N_2體積分?jǐn)?shù)分別為16.5%、0.8%、13%、69.7%的混合氣氛下對(duì)75Cr1鋼加熱保溫。通過(guò)正交實(shí)驗(yàn)研究了加熱溫度(975、1 050、1 125、1 200℃)和保溫時(shí)間(10、20、30、40min)對(duì)75Cr1鋼脫碳的影響規(guī)律。并與菲克第二定律的計(jì)算結(jié)果進(jìn)行了對(duì)比。實(shí)驗(yàn)結(jié)果表明:脫碳層深度隨著加熱溫度和保溫時(shí)間的增加而增加,并且當(dāng)溫度為1 200℃時(shí),增幅明顯變大;975℃時(shí)的實(shí)測(cè)值接近理論值,1 050、1 125、1 200℃時(shí),實(shí)測(cè)值遠(yuǎn)小于理論值;擴(kuò)散系數(shù)修正后計(jì)算值與實(shí)測(cè)值基本保持一致。
[Abstract]:In the laboratory to simulate the heating process of the field heating furnace, In this paper, the effect of heat preservation on 75Cr1 steel was studied by orthogonal experiment in a mixed atmosphere of 16.5% volume fraction of CO2O2H2OH2ON2 and 0.8% 1369.7% respectively. The effect of heating temperature and holding time 10203040min on the decarbonization of 75Cr1 steel was studied by orthogonal experiment. The experimental results show that the depth of decarburized layer increases with the increase of heating temperature and holding time. And when the temperature is 1 200 鈩，
