Description

Technical Field

[0001] This utility model relates to the field of furnace hearth lining construction technology, specifically to a furnace hearth lining construction structure using corundum silicon carbide material. Background Technology

[0002] The hearth is a key structural area of ​​the blast furnace, located between the center line of the first row of tuyeres and the bottom of the furnace. This area adopts a square design and contains components such as the taphole and tuyeres. Its main functions include containing high-temperature molten slag and iron, providing space for fuel combustion, and facilitating the discharge of molten iron. Modern blast furnaces generally use sloping structures, guide channels, and composite refractory materials to improve their resistance to erosion. The hearth needs to withstand high temperatures and chemical corrosion, and its service life needs to be extended through cooling systems and monitoring technologies. Corundum silicon carbide refers to refractory products made from fused brown corundum and silicon carbide used for the slide rails of steel rolling heating furnaces. Therefore, the hearth is generally cast using this material.

[0003] The existing construction structure for furnace hearth linings made of corundum silicon carbide is not convenient for demolding, making it inconvenient to use. Furthermore, the existing construction structure for furnace hearth linings made of corundum silicon carbide is not convenient for removing the inner liner, requiring manual operation, which results in low safety and poor practicality.
