Design and Application of Tapping Sleeve Brick

The tapping sleeve brick is the channel for the molten steel from converter to the ladle. It directly contacts with the molten steel and its life directly affects the steel making rhythm of the converter. From the structure, tapping sleeve bricks are divided into monolithic sleeve brick and split sleeve brick. The monolithic sleeve brick is generally used isostatic compression molding, split sleeve brick is used machine pressure molding.

Whether it is monolithic or split type, the inner holes is a circular structure of the through-hole. The hole size according to tapping time, and the wall thickness is generally 50-100mm. The hole shape is divided into straight and trumpet-shaped. Experiments show that the trumpet-shaped hole and the circular inlet shape, the tapping speed is faster, which means that the interference between the molten steel and the tap hole is weakened and the water flow is relatively stable, shortens the tapping time. There have many kinds of refractory products in our factory.
