Influence of clay refractory bricks on steel quality
For use clay refractory bricks need to be mixed with one or more liquids and stirred well and are highly fluid.
For use clay refractory bricks need to be mixed with one or more liquids and stirred well and are highly fluid. What is the impact on the quality of steel? The following is the relevant content organized by the editor:
In the steel smelting process, the interaction between the furnace lining refractory material and the molten steel in the molten pool and the resulting impact on the quality of the molten steel and steel mainly includes the following aspects:
As a result of clay refractory bricks, shedding, non-metallic inclusions are generated in the molten steel and steel. During: steelmaking, the furnace lining refractory bricks are eroded and structural changes occur in the decarburized and reactive layers of the bricks, resulting in relaxation. As a result of mechanical erosion of molten steel, slag, furnace gas, molten iron, bulk materials and scrap, the refractory material is dislodged and involved in the molten steel, forming non-metallic inclusions.
The nature of non-metallic inclusions in steel is quite different from that of the steel itself. From a mechanical point of view, the location of non-metallic inclusions is the stress concentration point of steel, the strength of steel, stiffness and other mechanical properties have a great impact. Therefore, non-metallic inclusions are one of the serious defects that affect the quality of steel.
Non-metallic inclusions are produced by the mutual reaction between the constituent elements of clay refractory bricks and the non-metallic elements in steel. Some elements of the refractory material are directly dissolved in the molten steel, increasing the oxygen, carbon and other non-metallic elements in the molten pool. Under certain conditions, the non-metallic elements in the steel water react with each other to form non-metallic inclusions. Similarly, clay refractory bricks can adversely affect the quality of molten steel and steel.
Clay refractory bricks are mainly used in the construction of coke ovens, as well as in the vaults of various glass and refractory brick hot kilns and other load-bearing parts. In hot blast stoves, high-temperature load-bearing is also used, but not for thermal equipment with temperature fluctuations below 600.
