The use and installation of Shi Ying Shuikou brick need to strictly follow relevant specifications and skills to ensure its stability and service life in high temperature environment. The following is a detailed description of the use method, installation precautions and use skills of Shi Ying Shuikou brick:

I. Method of use

(1) check the integrity of the brick body

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.

(2) daub fireclay

Apply a layer of fire mud evenly outside the nozzle brick, and then screw it into the hole of the seat brick to ensure that the nozzle brick is placed correctly.

(3) Depth control

The installation depth of nozzle brick should be moderate. If the upper end face of the nozzle brick is lower than the bottom of the bucket, the rapid cooling of molten steel may lead to cracks in the plug brick; If the upper end surface is higher than the bottom of the bucket, it will lead to the waste of molten steel.

(4) repair around

After the installation is completed, it is necessary to repair around the nozzle brick to ensure the tightness and prevent molten steel from infiltrating into the gap.

II. Precautions for Installation

(1) cooperate with grinding

Before installation, two adjacent bricks are matched and ground to remove defects on the bricks, so as to better seal the joints of the bricks and ensure the smooth bricklaying.

(2) Prevent molten steel from infiltrating.

Avoid molten steel from infiltrating into the gap between the nozzle brick and the plug rod or sleeve brick, which may lead to the brick body being damaged or partially falling off.

(3) controlling the temperature of molten steel

Too low temperature of molten steel may cause damage to nozzle brick, so it is necessary to strictly control the temperature of molten steel.

(4) Avoid too deep installation.

When the nozzle brick is put too deep, the molten steel may penetrate between the nozzle and the stopper, resulting in local falling off.

III. Skills of use

(1) preheating treatment

Before use, Shi Ying Shuikou brick should be properly preheated to avoid the brick cracking caused by sudden temperature change.

(2) Regular inspection

In the process of use, check the use status of nozzle brick regularly, and find and deal with possible cracks or damage in time.

(3) Reasonable control of pouring speed

The pouring speed should not be too fast to avoid excessive impact on the nozzle brick.

(4) prevent erosion

For the parts that are easy to be corroded by molten steel, materials with higher fire resistance (such as zirconium quartz sand) can be used for firing to prolong the service life.

Through the above methods and precautions, the service life and efficiency of Shi Ying Shuikou brick can be effectively improved, and its stability and reliability in high temperature environment can be ensured.
