【摘要】 在大连钢厂锻钢分厂3号半连续推钢式锻造加热炉的节能技术改造中,通过综合采用各项节能技术措施,取得了显著的节能及经济效果。生产统计吨钢油耗由改造前的269.29kg下降到187.35kg。炉膛热效率由原来的12.15％提高到27.76％。所研制的插件金属管式换热器,在烟气温度500～600℃的情况下,可将空气预热到400～500℃。采用重油电加热器,油温稳定地控制在130～140℃,降低了油的粘度,提高了雾化质量。更多还原

【Abstract】 A series of measures were adopted for modernization of semi-continous reheating furnace for forging at Dalian Steel Works. Much energy saving has been achieved: oil consumption per ton metal decreased from 269.29 to 187.35kg, the heat efficiency increased from 12.15% to 27.76%. The metal-tube type heat-exchanger of unique structure preheats combustion air up to 400-500℃ if the temperature of exhaust gas is 500-600℃. With electric heater the temperature of the oil kept in the range of 130-140℃ the viscosity of the oil can be reduced so improves atomization evidently.更多还原
