Embodiment 1
[0018] This embodiment is a 90t stainless steel ladle, and the working lining of the ladle is made of magnesia-calcium bricks. The bricks of the working lining of the ladle wall are 150mm long and 100mm thick, the bricks of the slag line are 250mm long and 100mm thick, and the free space bricks are 150mm long and thick. 100mm, the size deviation of the ladle-clad magnesia-calcium brick is ±3mm (the allowable deviation of the size of the dry-laid magnesia-calcium brick is ±2mm).
[0019] This embodiment includes the following steps in sequence:
[0020] Ⅰ The working lining of the ladle bottom is dry-built with magnesia-calcium bricks, and the working lining of the ladle wall is wet-built with magnesia-calcium bricks and magnesia-chrome fire clay. Before the lining of the ladle wall is built, mix the magnesia-chrome fireclay evenly: stir the dry-mixed magnesia-chrome fireclay with a mud mixer for 3 minutes, add water, the amount of water to be added is 13%, and the water temp...
Embodiment 2
[0024] This embodiment is a 180t stainless steel ladle, and the working lining of the ladle is made of magnesia-calcium carbon bricks. The bricks of the working lining of the ladle wall are 200mm long and 100mm thick, the bricks of the slag line are 250mm long and 100mm thick, and the free space bricks are 200mm long and The thickness is 100mm, and the size deviation of the magnesia-calcium-carbon brick on the wall of the ladle is ±3mm (the allowable deviation of the size of the dry-laid magnesia-calcium-carbon brick is ±2mm).
[0025] This embodiment includes the following steps in sequence:
[0026] Ⅰ The working lining of the ladle bottom is dry-built with magnesia-calcium-carbon bricks, and the working lining of the ladle wall is wet-built with magnesia-calcium-carbon bricks and magnesia fire clay. Before the working lining of the ladle wall is built, mix the magnesia fireclay evenly: stir the dry mix magnesia fireclay with a mud mixer for 3.5 minutes, add water, the amo...
