传统的缝式炉与普通的锻造室式炉的结构基本类似,它的热效率大多不到10％,正常生产时炉口冒火,劳动条件很差。 为此,冶金部马鞍山钢铁设计研究院、无锡市太湖耐热铸造厂、常州钢铁厂联合研制了节能型燃油缝式炉。其技术关键是:设计了高效喷流辐射换热器和金属对流换热器,两次回收烟气余热,将助燃空气预热到500℃左右;选用改进的S型双管全热风油喷嘴,利用热风取代压缩空气
The traditional seam furnace and ordinary forging chamber furnace structure is basically similar, most of its thermal efficiency less than 10%, the normal production of flue gas stove mouth, poor working conditions. To this end, the Ministry of Metallurgical Maanshan Iron and Steel Design and Research Institute, Wuxi Taihu heat-resistant foundry, Changzhou Steel jointly developed a fuel-efficient fuel seam furnace. The key technical points are as follows: designing an efficient jet radiation heat exchanger and a metal convection heat exchanger, recovering the waste heat of the flue gas twice, preheating the combustion air to about 500 DEG C; and adopting the improved S-type double- Use hot air instead of compressed air
