[Original Article] Steel ladle capacity-increasing transformation and optimizing practice of ladle bottom technology

[vc_row][vc_column][vc_column_text]After a company’s capacity expansion ladle went online, the quality of molten steel was increased from 290t to 310t, which directly laid the foundation for stable production and excellent production in the steelmaking department. The annual production capacity of the first steelmaking converter increased by 7% to about 630,000 tons. The total annual production capacity reached 9.7 million tons, close to Pohang Guangyang’s production level. The ladle capacity expansion and transformation effectively promoted the increase of steelmaking output, thereby effectively reducing the impact of the single furnace auxiliary on the output in front of the furnace. At the same time, due to the increase of single furnace output, the power cost per ton of steel, refractory materials and labor costs were reduced, greatly reduced Production cost per ton of steel.

 

At the same time, the adoption of the ladle bottom slit composite diffused breathable brick and the new coal oxygen gun and the improvement of the bottom blowing process have improved the blowing rate from 99.84% and stabilized above 99.98%, and the life of the bottom blown brick has also been significantly improved, Reaching the level of advanced steel mills such as Baosteel, South Korea’s Pohang and Nippon Steel.
