Production Practice of Increasing Primary Ladle Age of 120 t Refining Ladle
Aiming at the issue of low primary ladle age,through analyzing the mechanism of brick type damage in various parts of the ladle,a series of improvement measures have been proposed,such as optimizing the refractory materials in various parts of the ladle,laying protective measures in key parts of the ladle,using high-performance and long-life breathable bricks,and optimizing the turnover rhythm of the ladle,etc.The practical verification was carried out in a 120 t refining ladle.The practical results show that through the above improvement measures,the average primary age of the ladle has been increased from 42.35 heats to 62.77 heats,with the highest ladle age reaching 72 heats.The cost of refractory materials and ladle investment has significantly decreased,and it has greatly promoted the stable operation of production organization.
