Problems solved by technology
[0005] The main deficiency in this patent is: compared with the harsh and complicated working conditions in the thin strip continuous casting process, the wear resistance and thermal shock resistance of the materials selected in each area of the side sealing plate are poor, and it is easy to cause the traditional The bonding method fails, and the service life of the entire side sealing plate is limited, which seriously affects the production efficiency of thin strip continuous casting; the structure of the entire side sealing mechanism is complex, such as area III is a layered special-shaped part, and area II is a high-tech ceramic special-shaped part. Difficult; cannot guarantee thin strips with good edge quality; high production cost

Embodiment Construction
[0022] In the following, in combination with Figure 1-3, take the side sealing plate installed on a roll with a roll diameter of 320mm on a twin-roll continuous casting machine as an example to illustrate it:
[0023] First determine the material, shape and size of each part of the side sealing plate. According to the specific size of the continuous casting device, determine the specific shape and size of each part of the side sealing plate. Substrate 1 can be an asbestos cement board prepared by "Chongqing Asbestos Cement Board Factory". Substrate 1 is an isosceles trapezoidal plate or a triangular plate. , the lower bottom is narrow, its height is 170mm, and its thickness is 20mm. There are two isosceles with different depths connected to each other and matched with the heat insulating plate 2 and the ceramic plate 3 respectively on the upper and middle lower parts of the same vertical centerline on one side of the substrate. Trapezoidal groove and rectangular groove, the d...

The present invention relates to a side sealing equipment for seal-casting space in metal strip double-roll continuous casting machine, and its technical scheme is as follows: a pair of side sealing mechanisms are respectively and oppositely mounted at sides of end face of roll end of double-roll continuous casting machine, and the end face of its every roll end is opposite to the working face of side sealing plate of said side sealing mechanism and close to it, every side sealing mechanism includes side sealing plate, supporting mechanism for supporting said side sealing plate, supporting component on the supporting mechanism, shortened or extended elastic supporting component between the side sealing plate and supporting component and shortened or extended elastic component between them.
Description
Technical field: [0001] The invention belongs to a side sealing device of a metal strip twin-roll continuous casting machine, in particular to a side sealing device used for sealing a casting space in a thin metal strip twin-roll continuous casting. Background technique: [0002] The patent number is US6082437, and its invention title is "Side wall for closing off the casting space of a plant for the twin-roll continuous casting of thin metal strip" . In this patent, different materials are selected for different working conditions of each part of the side sealing plate, and the side sealing plate is divided into three areas: the upper middle part of the side sealing plate is in direct contact with the metal liquid area I, and the area where the side sealing plate is in contact with the edge of the roll The contact area II between the lower end of I and the metal liquid, the solidification zone, and the surface area III of the contact surface between the lower end of the si...
