The reduction of waste gas losses is often the most effective and economic way to increase the efficiency of industrial furnaces.Regenerative burners achieve highest efficiency but one has accept a certain expenditure for cyclic switching and exhaust gas suction.This might not be justified for smaller burner sizes and furnaces.A new gap flow recuperative burner reaches almost the same efficiencies with a recuperative system.To increase the working temperature range,the gap flow heat exchanger can be combined with a ceramic heat exchanger.One important aspect which has to be considered is thermal NO-formation,especially when preheating the combustion air.The use of flameless oxidation technology enables lowest NOx emissions despite high air preheat temperatures.

高频感应焊(HFW)管线管焊缝冲击韧性存在不稳定现象,在进行同一组的三个试样夏比冲击试验中,焊缝冲击功值出现“两高一低”情况.通过扫描电镜分析了冲击试样残样的断面,冲击功低值的试样断面更平整且断面有残留氧化物夹杂.结合HFW焊管制管中焊接及热处理工艺特点,分析了焊缝冲击功不稳定的原因以及焊接过程中氧化物夹杂形成的原因,提出了控制氧化物夹杂的措施.
中间包电磁感应加热技术,可以有效地补偿钢液的热损失,利于实现低过热度恒温浇注,进而增加等轴晶的比率,改善铸坯质量.中间包感应加热技术越来越受到人们的广泛重视.本研究建立了感应加热电磁、流动和传热的三维数学模型,并对模型的可靠性进行了验证.研究表明,感应电流在注流室、分配室以及两个通道间形成了电流回路,通道内的电流密度远大于注流室与浇注室的电流密度.由于集肤效应与邻近效应,通道靠近线圈一侧的磁场比其
