In the process of using sleeve brick, we need to pay attention to the following points to ensure its performance and service life:

I. Inspection before installation

Before installing the sleeve brick, it is necessary to carefully check its appearance to ensure that there are no cracks, defects or other obvious quality problems.

Check the dimensional accuracy of sleeve brick to ensure that it meets the design requirements, so as to ensure the close cooperation with plug brick and nozzle brick.

II. Matters needing attention in the installation process

Installation sequence: Installation should be carried out in the correct order. First install the seat brick, then install the nozzle brick, and finally install the sleeve brick.

Sealing inspection: the contact surface between sleeve brick and plug brick and nozzle brick should be coated with refractory mud to ensure good sealing and prevent molten steel from leaking.

Firmly fixed: press the cover at the end of the sleeve brick, and press the sleeve brick with nuts through the cover to ensure that it will not loosen during use.

III. Maintenance during use

Avoid thermal shock: during use, the sleeve brick should be prevented from being subjected to sharp temperature changes to prevent thermal shock damage.

Prevention of mechanical impact: During operation, excessive mechanical impact on the sleeve brick should be avoided to avoid damage.

Regular inspection: During use, the wear and tear of sleeve bricks should be inspected regularly, and the damaged parts should be found and replaced in time.

IV. Safety operation procedures

Personal protection: When installing and maintaining sleeve bricks, operators must wear labor protection articles such as safety helmet and gloves.

Handle with care: handle with care during handling and installation to avoid collision and throwing.

Safety of aerial work: If installation or maintenance work is carried out at high places, necessary protective measures should be taken, such as fastening safety belts to ensure the scaffold is stable.

V. Storage and transportation

Storage conditions: sleeve bricks should be stored in a dry and flat place to avoid moisture and damage.

Transportation protection: During transportation, appropriate packaging and fixing measures should be adopted to prevent collision and damage.

Through the above precautions, the service life of sleeve brick can be effectively prolonged and its stability and safety in high temperature environment can be ensured.
