An overflow brick structure adapting to high temperature creep

Abstract

The invention discloses an overflow brick structure adaptable to high temperature creep, which belongs to the technical field of glass production and forming equipment, and includes an overflow brick, the inner cavity of which is embedded with an overflow ridge, and two overflow ridges The end is provided with a limit structure to provide a limit force, and the middle is provided with a support adjustment structure to provide a support force. The limit force and support force are located in the linear direction of the overflow brick sinking through high temperature creep. Above; the support adjustment structure is equipped with a tensile force adjustment mechanism to adjust the size of its support force, so as to achieve structural optimization to avoid high-temperature creep and sinking deformation of the overflow sill, and then effectively solve the impact of overflow brick high-temperature creep The purpose of the influence of the production process.

Description

technical field [0001] The invention belongs to the technical field of glass production and molding equipment, and in particular relates to an overflow brick structure suitable for high temperature creep. Background technique [0002] The overflow brick is an important process equipment for the production of TFT-LCD liquid crystal glass substrates. Under high temperature conditions, the overflow brick will slowly creep and sink. The uneven flow distribution in the direction causes the quality parameters such as the thickness difference and stress of the glass plate to exceed the standard. Especially for the large-sized overflow bricks, due to the large size of the brick body and the heavy weight of the overflow brick body, the high-temperature creep rate is faster, which is not suitable for large-scale overflow bricks. The stability of the production process has an adverse effect. When the creep value of the overflow brick reaches a certain value, the production process must...
