链式炉现在全国薄板行业中约占60％左右有60台,是50年代从鞍钢开始使用至今,已30余年,无什么改进。但当今处于世界能源危急时代,它耗能之大引人关注。在轧钢行业中,链式炉几乎都不能进入特等炉,而后起之秀——步进炉,逐渐进入特等炉的行列,而且各种指标均能满足当今生产的要求。仅从能耗的角度来讲,全国轧钢行业60台链式炉若改造为步进炉,仅炉爪带走的热量,则一年可节约标准煤2～2.3万吨价值200～230万元。我厂步进炉为φ800×1200薄板轧机配套,将硅钢板坯1040×240×9.8加热一火迭
Chain stove now about 60% of the national sheet metal industry has 60 units, is the 50’s from Ansteel began to use, more than 30 years, no improvement. Today, however, it is in a critical period of energy crisis in the world and its energy consumption has drawn great attention. In the rolling industry, the chain furnace almost can not enter the special furnace, and the rising star - step furnace, and gradually into the ranks of special furnaces, and various indicators can meet the requirements of today’s production. Only from the energy point of view, the country’s 60 steel rolling chain chain furnace if the transformation into a step furnace, only the heat away from the furnace claw, the annual savings of 2 to 23,000 tons of standard coal worth 200 to 2.3 million yuan . I plant into the furnace for φ800 × 1200 sheet mill supporting the silicon steel slab 1040 × 240 × 9.8 heating a fire Diego
