Converter Kilns and furnace bricks: High-Temperature Symbiotic Smelting Partners

Converter kilns are the core carriers of steelmaking.

Furnace bricks for converters are the core lining that protects the long-term operation of the kiln. The two are interdependent and work synergistically to support the crucial link in high-temperature smelting. Then the high-temperature operating environment of the kiln places extreme demands on the performance of the furnace bricks. And the quality of the bricks directly determines the service life and operational safety of the kiln.

The Role of High-Quality furnace bricks in Converters

Converter kilns operate at temperatures above 1600℃ year-round and face the dual challenges of molten steel erosion, slag corrosion, and sudden temperature changes. So they use these furnace bricks to adapted these conditions. High-quality furnace bricks are made from heat-resistant raw materials. In order to possessing strong resistance to erosion, scour, and thermal shock. They fit tightly against the inner wall of the kiln. In order to forming a robust protective layer that isolates the kiln body from the high temperatures and molten steel.

Depending on the varying degrees of erosion in different parts of the kiln, appropriate brick materials must be selected:

The slag line is susceptible to slag erosion. So choose magnesia bricks for strong slag resistance. The taphole is subjected to significant impact from molten steel. Then high-strength magnesia-carbon bricks are used to ensure balanced stress distribution throughout the kiln. So proper selection and standardized installation of furnace bricks can maximize the extension of kiln maintenance cycles and reduce operating costs.

The kiln is made stable and durable by the furnace bricks. And the furnace bricks are made valuable by the kiln. Together, they uphold their mission in high-temperature smelting. In order to providing a solid guarantee for the efficient and safe progress of steelmaking.
