The installation method and steps of Shi Ying Shuikou Brick should be carried out in strict accordance with the specifications to ensure its stability and service life in high temperature environment. The following are detailed installation methods and precautions:
Before installation, Shi Ying Shuikou brick must be carefully inspected for cracks, defects or other defects. Only complete nozzle bricks can be used for installation.
Apply a layer of fire mud evenly outside the nozzle brick, usually using magnesia-chrome refractory mud to ensure uniform and full application, and the contact joint is not more than 1 mm.
Screw the nozzle brick into the hole of the seat brick to ensure that the nozzle brick is placed correctly. The installation depth of nozzle brick should be moderate to avoid being too high or too low.
Pour a proper amount of ramming material around the nozzle brick and ram it tightly with special tools. When tamping is slightly lower than the water level on the nozzle, install the seat brick.
The joint between the seat brick and the nozzle brick is wet-laid with magnesia-chrome refractory slurry to ensure that the seat brick and the nozzle brick are concentric. After fixing the brick, continue to tamp the surrounding layers until they are flush with the castable.
Repair around the nozzle brick to ensure sealing. Filling drainage sand between the seat brick and the nozzle brick, and laying heat insulation material on the drainage sand.
After the installation is completed, check whether the nozzle brick is installed in place and ensure that its upper end face is flush with the bottom of the bucket.
Matching grinding: before installation, two adjacent bricks are matched and ground to remove defects on the bricks and make the joints of the bricks better sealed.
Avoid excessive force: during installation, avoid applying excessive mechanical force to the nozzle brick.
Temperature control: Before use, properly preheat the Shi Ying Shuikou brick to avoid the brick cracking caused by sudden temperature change.
Prevent molten steel from infiltrating: fill drainage sand and heat insulation material between the nozzle brick and the seat brick to prevent molten steel from infiltrating into the gap.
Through the above steps and precautions, the stability and reliability of Shi Ying Shuikou brick in the installation process can be effectively ensured, and its service life can be prolonged.
