Предпазни мерки за леки огнеупорни тухли

1. Lightweight refractory bricks have large porosity and loose structure, so they cannot be used for parts that are in direct contact with molten slag and liquid metal.

2. The mechanical strength is low and cannot be used for load-bearing structures.

3. The wear resistance is very poor, so it is not suitable for the parts that are in contact with the charge and are severely worn.
