【摘要】 分析了炉壁黑度对炉膛辐射换热流的影响 ,分别对火焰直接加热炉和间接加热炉进行了讨论。结果表明 :炉壁黑度对制品表面净辐射热流几乎没有影响 ,因而增大或减少炉壁黑度对强化炉内辐射换热没有意义更多还原

【Abstract】 Effect of furnace wall emissivity on surface heat flux of heated stock is analyzed for direct firing furnace and indirect heating furnace.The results show that furnace wall emissivity has little effect on surface heat flux of heated stock.更多还原
