Masonry of ladle integral breathable brick and nozzle brick

The quality of the ladle masonry is related to the service life of nozzle bricks, breathable bricks, etc., and may also affect the quality of the finished steel products. Before the masonry, the lining material of the ladle needs to be removed. Before unpacking, a certain amount of preparation is required. First, carefully check the thickness of the ladle wall, bottom, nozzle brick, and air-permeable brick to see if there are large brick joints. Before entering the ladle, you need to observe whether there is any hanging or loose steel slag on the upper side of the ladle, and make corresponding treatments to avoid the steel slag falling during the operation and causing injury.

After the unpacking is completed, it is the masonry of integral breathable bricks, nozzle bricks and so on.

Masonry of integral air-permeable bricks: clean up the air-permeable brick parts reserved at the bottom of the package; use the crown crane to align the steel tube of the air-permeable brick with the reserved holes in the bottom of the steel ladle, and sit and sit; The gap between them is filled with castable.

Masonry brick: Check the status of the brick, and ensure that there are no cracks, deformations, etc. that affect the use of the brick. Generally speaking, the installation accuracy requires that the height of the brick brick end face is less than 125mm from the base plate of the fixed frame of the mechanism, and Measured from any position, the size fluctuation is within 1mm; during installation, put the nozzle block brick into the positioning ring, rotate the block brick properly, so that the cement and the block brick are in good contact, and sit on the solid block brick, at this time the thickness ≤1mm ; The gap between the periphery of the seat brick and the bottom brick is filled with the seat brick repair material.

The construction of integral air-permeable bricks and nozzle bricks occupies a large proportion in the ladle masonry process, and is also essential for steel refining.
