日本钢管公司京浜钢铁厂开发一项既不降低炉子的热效率又能实现无氧化加热的双层气氛新燃烧技术,该厂于1987年对现有炉焊管坯加热炉进行了技术改造,使氧化铁皮烧损量减少了70％。
Japanese steel company Keihin Steel Works has developed a new two-stage atmosphere combustion technology that will not reduce the thermal efficiency of the furnace and will achieve non-oxidative heating. The plant reformed the existing furnace for furnace tubes in 1987 to make the scale Burns reduced by 70%.
