Description

Technical Field

[0001] The utility model relates to the technical field related to flow steel bricks, in particular to a double-branch flow steel brick. Background Art

[0002] Flow steel bricks refer to hollow refractory bricks built in the grooves of the bottom plate for ingot casting to connect the steel bricks and the ingot mold, commonly known as soup bricks. Flow steel bricks are generally rectangular hollow clay bricks with various specifications. In order to reduce the resistance of molten steel flow and prevent steel leakage, the flow steel bricks are required to have smooth inner holes, regular shapes and tight joints. Mullite refers to a general term for a series of minerals composed of aluminosilicates.

[0003] Most of the existing flow steel bricks are made by one-piece molding process. When splicing, the flow steel bricks are only spliced ​​through the protrusions they carry to form a steel flow channel. During the flow of molten steel, the flow steel bricks are easily vibrated by the impact of liquid steel or collided with external forces, causing cracks, which leads to the outflow of liquid steel. It is necessary to stop work and rearrange the steel flow channel, which is inconvenient. Utility Model Content
