The Main Differences between Converters And Refractory Bricks

A converter is a metallurgical equipment used in steel production, mainly for converting molten iron into molten steel. Refractory bricks are special building materials used for lining high-temperature equipment such as converters, blast furnaces, and hot blast stoves to resist high temperatures and chemical erosion.

Refractory bricks are usually made of refractory clay or other refractory raw materials, featuring high refractoriness, good thermal shock resistance and slag resistance. Converters are welded from steel plates, with refractory bricks lined inside to form the furnace lining.

During operation, converters undergo drastic temperature changes and mechanical impacts, with the internal temperature reaching over 1600℃. Refractory bricks need to maintain structural integrity and functionality in such extreme environments to prevent erosion by molten metal and slag.

The service life of a converter depends on various factors, including operating conditions, maintenance, and the quality of the selected refractory bricks. As part of the converter's inner lining, the quality of refractory bricks directly affects the converter's service life.
