Problems solved by technology
Since the sub-plate is in direct contact with molten steel, the consumption of the sub-plate is relatively large, and the requirements for the sub-plate are also high; the structure of the left and right sides of the mother plate is asymmetrical, and it is also prone to cracking or even breaking due to the impact of thermal shock during the casting process

Embodiment Construction
[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0021] figure 1 and figure 2 It is a schematic diagram of the new composite structure skateboard. The composite structure skateboard of the present invention is composed of an outer shell 1, an expansion layer 2, a wear-resistant inner lining 3, an upper adhesive layer 4, a lower adhesive layer 5, a left slab 6, and a right slab 7. The left plate brick 6 and the right plate brick 7 are made of inexpensive and high-quality refractory materials, such as aluminum-carbon materials, aluminum-carbon-zirconium materials, and the like. The shell 1 is made of metal materials, such as Q235, Q345, etc., which can produce certain elastic deformation and plastic deformation. The wear-resistant lining 3 is made of zirconia material with good thermal shock stability, corrosion resistance and erosion resistance. The left plate brick and the right plate brick are spl...

The invention discloses a sliding board of a composite structure and belongs to the technical field of metallurgy continuous casting equipment. The sliding board is used in a steel ladle sliding nozzle system and comprises an outer shell, an expansion layer, a wear-proof lining, an upper adhesion layer, a lower adhesion layer, a left board brick and a right board brick. The upper surface of the left board brick and the upper surface of the right board brick are located on the same plane. The left board brick and the right board brick are spliced to form a sliding board body. A complete conic hole of the sliding board body is formed by a semicircular conic hole of the left board brick and a semicircular conic hole of the right board brick. A cylindrical hole is formed in the center of the wear-proof lining and serves as a casting opening. The upper adhesion layer is located between the conic hole of the sliding board body and the wear-proof lining, the lower adhesion layer is located between the lower surface of the sliding board body and the outer shell, and the expansion layer is located between the periphery of the sliding board body and the outer shell. The sliding board of the composite structure has the advantages that the sliding board body can be prevented from cracking or being broken and the sliding board of the composite structure is long in service life, safe, reliable and the like.
Description
Technical field: [0001] The invention belongs to the technical field of metallurgical continuous casting equipment, and in particular relates to a sliding plate with a combined structure, which is used in a ladle sliding nozzle system. Background technique: [0002] The sliding nozzle system is a control device for molten steel in the casting process of the continuous casting machine. It can precisely adjust and control the molten steel flow from the ladle to the continuous casting tundish, and has the advantages of good controllability and high production efficiency. The sliding plate is its most important part, and the flow of molten steel can be directly controlled by the movement of the sliding plate. During the working process, the sliding plate needs to withstand repeated chemical and physical erosion of molten steel and strong thermal shock. At present, domestic skateboards are generally aluminum-carbon integral skateboards. During use, due to the scouring of high-te...
