Description
Technical Field
The utility model relates to the technical field of blast furnace ironmaking equipment, in particular to a ceramic cup side wall of a blast furnace hearth, which is composed of embedded and bonded refractory brick rings.
Background
The ceramic cup lining body of the blast furnace hearth is in a high-temperature and high-pressure situation with molten slag iron, coal gas and harmful elements and is damaged by chemical erosion, mechanical scouring, vibration damage, high temperature and thermal shock and the like. The extent to which these damaging factors affect the functional life of the ceramic cup liner depends above all on the metallurgical strength of the blast furnace, the higher the metallurgical strength, the greater their degree of damage. Although the practical application of the ceramic cup lining body proves that the ceramic cup lining body has the comprehensive effects of protecting the hearth carbon bricks, prolonging the service life of the blast furnace and being beneficial to environmental protection, along with the improvement of the production efficiency of the blast furnace, the hearth ceramic cup formed by standard common small refractory bricks needs to improve the stability and the tightness of the brickwork while improving the physical and chemical properties of materials, provides a good brickwork structure foundation for the performance of the materials and further meets the service life requirement of the blast furnace with high smelting strength.
When the ceramic cup lining body is built by small refractory bricks, the standard refractory bricks with the shape and size specifications of G-1-G-4 in YB/T5012 or the common type refractory bricks with the shape and size similar to the G1-G-4 specification are usually selected.

Because six surfaces of the used refractory bricks are flat surfaces, all the refractory bricks in the refractory brick rings forming the ceramic cup wall have no structural constraint except masonry slurry, and harmful substances such as iron slag and the like easily enter linear bonding brick joints to enter circumferential inter-ring brick joints with larger back width or directly contact and erode carbon bricks; meanwhile, as the refractory bricks in the brick rings are not structurally constrained, the refractory bricks can displace under the vibration and impact caused by nonuniform expansion and violent flowing of slag iron of all parts of brickwork; when the local refractory bricks are corroded and damaged, other surrounding refractory bricks are easy to shift, even topple and collapse. These defects can cause the side wall of the ceramic cup to lose stability and tightness in a high-strength smelting blast furnace hearth earlier, shorten the functional life of the ceramic cup and bring adverse effects on the protection of carbon bricks and the life of the blast furnace.
