Hanging structure for preventing fracture of 3D high-aluminium glass runner cover board brick

Abstract

The invention discloses a hanging structure for preventing fracture of a 3D high-aluminium glass runner cover board brick. The hanging structure comprises a main beam, wherein hanging lugs are respectively arranged at the two ends of the main beam. The hanging structure also comprises a plurality of clamping boards for connecting the cover board brick, wherein the clamping boards are arranged under the main beam in sequence; a gap is left between the two adjacent clamping boards; the two sides of the clamping boards are connected to the main beam by connectors. The hanging structure disclosedby the invention has the beneficial effects that the plurality of clamping boards are arranged, equivalently the original one clamping board is split into the plurality of clamping boards, each clamping board is connected to the main beam by adopting the connector and is hung, the stressing is balanced, the gap is left between the adjacent clamping boards and a space is reserved for the expansionamount of a hanging part, so that the problem that the hanging part is wholly deformed by thermal stress deformation and nonhomogeneous expansion and the like of the two sides to cause fracture of the cover board brick due to deformation of the hanging part is avoided, and the purpose of protecting the cover board for safe use is achieved.

Description

technical field [0001] The invention belongs to the field of float glass preparation equipment, in particular to a hanging structure for preventing 3D high-alumina glass runner cover bricks from breaking. Background technique [0002] 3D high-alumina float ultra-thin electronic glass is a manufacturing industry, and the safe operation of process equipment is the most basic prerequisite for production safety and profit guarantee. Nowadays, while developing new glass technologies, glass manufacturers in the world are constantly optimizing the safety configuration of production lines, and transforming equipment structures and installation methods. With the continuous development of the world's high-tech industry, the demand for 3D high-alumina ultra-thin glass in the international market is increasing, especially for ultra-thin glass substrates for flat panel displays and mobile phones. Therefore, glass manufacturers are focusing on energy saving, environmental protection, info...

AI Technical Summary

Problems solved by technology

Since the high-alumina ultra-thin glass flow channel is a high-temperature area (1200-1300 ° C), and there is a temperature difference between the front and the back, there is a difference in the expansion of the stainless steel material before and after the hanging part, and the cover brick itself is made of fused silica, which is in a high-temperature environment. The expansion coefficient under the glass is significantly smaller than that of steel, which is not a big problem when ordinary float glass is used at a relatively low temperature or in a small operation. However, because high-alumina glass requires a higher glass liquid temperature, the flow channel The temperature is relatively high, which in turn increases the temperature difference between the cover brick and the hanging parts, and the cover brick is broken due to the deformation of the hanging parts.
