Precast block has the advantages of convenient construction, good overall integrity, strong resistance to arc radiation, and resistance to rapid cooling and heating.

 

Precast Block, also known as refractory precast block or refractory precast shapes, is a prefabricated refractory component manufactured through vibration casting or molding processes using high-quality refractory aggregates, binders, and additives. It is widely used in BOF (Basic Oxygen Furnace) and EAF (Electric Arc Furnace) systems to improve installation efficiency, thermal shock resistance, and service life.

 

Compared with traditional brick masonry, precast refractory blocks provide faster installation, higher dimensional accuracy, and lower maintenance costs, making them ideal for modern steelmaking operations.
