Reverberating furnaces
Reverberating furnaces are key equipment in metal smelting, operating on the core principle of high-temperature reflective heat transfer. Kiln bricks, used as the core lining of the furnace body, form the “first line of defense” ensuring stable operation. The two are mutually compatible and work synergistically, constituting the core system of smelting operations.
The operating characteristics of the reverberating furnace determine the selection standards for the kiln bricks. Because the quality of the bricks directly affects the furnace lifespan and smelting efficiency.
The connection between reverberatory furnaces and kiln bricks
The reverberating furnace maintains temperatures above 1500℃ year-round. The combined effects of furnace gas and molten slag corrosion, as well as material erosion, place stringent requirements on the temperature resistance and corrosion resistance of the kiln bricks.
Kiln bricks suitable for reverberating furnaces
Kiln bricks suitable for reverberating furnaces are made from high-purity refractory raw materials using precise processes, possessing both excellent thermal stability and structural strength. They fit tightly against the furnace wall, forming a sealed protective layer that isolates the furnace body from the high temperatures and molten slag. In order to ensuring the structural integrity of the furnace.
Based on the varying operating conditions of different parts of the reverberatory furnace, kiln bricks must be scientifically selected:
The furnace top, subjected to the strongest high-temperature radiation, uses high-temperature resistant silica bricks.
The molten pool area, severely affected by slag erosion, uses high-alumina bricks with strong slag resistance. In order to ensuring suitable operation for all parts of the furnace.
Properly laid kiln bricks can extend the reverberatory furnace’s maintenance cycle, reduce operating costs, and contribute to efficient smelting.
The reverberatory furnace provides the carrier for the kiln bricks to realize their value, while the kiln bricks provide the foundation for the safe operation of the reverberatory furnace. The two mutually enhance each other during high-temperature quenching. In order to providing a solid guarantee for the stable development of the metal smelting industry.
