800 t挤压机底燃式燃油棒坯加热炉

随着燃烧技术的不断进步，在简易直火斜底式炉取得成功的基础上，将ＲＬ型贯通式辐射电炉改造为底燃式燃油棒坯加热炉。简要介绍了该炉的结构、加热原理及节能效果。通过近一年的实际应用表明：该炉完全能满足铝合金挤压生产的工艺及环保条件要求，而且升温速度快，少加热惯性和噪音污染，工节和使用性能均优于原辐射电炉。

Bottom-burning Type Oil-fired Furnace for Heating Billets Combined with 800 t Extruder

On the basis of the progress of burning technique and the success on the simple direct firing oblique bottom furnace,a straight through type electric radiatioin heating furnace is reformed to a bottom burning type oil fired furnace for heating billets.In the paper,the author introduces its structure,heating and energy saving effect.It is shown after near one year operation that the furnace can meet the requirements of the aluminum alloy extrusion and its environment protection and has the advantages of rapid heating,less heating inertia and noise,and better technological and operating performances than the original radiation type electric furnace.: On the basis of the progress of burning technique and the success on the simple direct firing oblique bottom furnace,a straight through type electric radiatioin heating furnace is reformed to a bottom burning type oil fired furnace for heating billets.In the paper,the author introduces its structure,heating and energy saving effect.It is shown after near one year operation that the furnace can meet the requirements of the aluminum alloy extrusion and its environment protection and has the advantages of rapid heating,less heating inertia and noise,and better technological and operating performances than the original radiation type electric furnace.
