对采用连铸工艺生产的不添加Mo元素的10NiCrMoV球扁钢进行了火工适应性研究.结果表明,这种10NiCrMoV球扁钢火工适应性较差.经800℃火工工艺后,由于珠光体量的减少和形变强化效果的消除造成球扁钢强度显著下降;经800℃水火工艺后,出现了大量的马氏体和大颗粒渗碳体造成球扁钢塑性急剧下降.
對採用連鑄工藝生產的不添加Mo元素的10NiCrMoV毬扁鋼進行瞭火工適應性研究.結果錶明,這種10NiCrMoV毬扁鋼火工適應性較差.經800℃火工工藝後,由于珠光體量的減少和形變彊化效果的消除造成毬扁鋼彊度顯著下降;經800℃水火工藝後,齣現瞭大量的馬氏體和大顆粒滲碳體造成毬扁鋼塑性急劇下降.

The influence of flame process on the non-molybdenum continual casting l0NiCrMoV bulb flat steel was researched.The results show that flame process flexibility of non-molybdenum 10NiCrMoV bulb flat steel is weak.The strength of 10NiCrMoV bulb flat steel is remarkably declined because of the decrease of pearlite and disappearance of distortion strengthening after flame process at 800℃,the plasticity of bulb flat steel is remarkably declined because lots of martensite and cemantite appear after flame processat 800℃ and water cooling.
