我厂现有19M~3小高炉一座。由于高炉有效容积小,冶炼周期短,炉况易波动,变化大,给高炉操作带来一定的困难。生产斗争的实践使我们不断认识到:在坚持“精料”工作的基础上,努力摸索小高炉的操作规律,不断提高操作技术水平,保证炉况顺行,这是小高炉夺取优质、高产、低耗的不可忽视的一个重要方面。高炉操作的主要任务,就是要保证炉料和煤气流在高炉截面上的合理分布,最大限度地利用煤气中的热能和化学能。上升煤气流和下降炉料是高炉冶炼过程中,许多矛盾中的
I plant a 19 M ~ 3 small blast furnace. Due to the effective volume of the blast furnace, smelting cycle is short, easy to fluctuate fluctuations in the furnace conditions, changes in the blast furnace operation to bring some difficulties. The practice of production struggle has constantly led us to recognize that on the basis of adhering to the “concentrate” work, we must try our best to explore the operating rules of the small blast furnace, continuously improve the operation skill level and ensure the furnace running smoothly. This is the reason why the small blast furnace wins the high quality, An important aspect that can not be ignored. The main task of blast furnace operation, is to ensure that the charge and gas flow in blast furnace section of a reasonable distribution, to maximize the use of gas in the heat and chemical energy. Ascending gas flow and falling charge are many contradictions in blast furnace smelting process
