Description

Substrate glass shaping traction mechanism and annealing furnace

Technical Field

The invention belongs to the technical field of substrate glass production, and particularly relates to a substrate glass forming traction mechanism and an annealing furnace.

Background

In the production of substrate glass, the overflow method is a widely used technique for manufacturing high-generation substrate glass. The main process for producing the substrate glass by adopting the overflow method comprises the following steps: the high-temperature molten glass flows out of the glass melting furnace, and flows into the overflow brick device after clarification and homogenization treatment; at the bottom of the overflow brick, high-temperature glass liquid is fused and drawn into continuous glass sheets by a traction device, and the continuous glass sheets are rapidly cooled and solidified by a cooling device to form substrate glass. The whole process needs to strictly control technological parameters such as temperature, pressure and the like, and meanwhile, the normal operation and maintenance of equipment are maintained.

The overflow method involves gradually cooling the molten glass in a high temperature molten state using a draw-down traction system to form a continuous glass sheet. In this process, the pulling rolls are the key components to achieving sheet stretching. The traction long roller ensures that high-quality substrate glass meeting the requirements is produced through functions of traction, support, fixation, temperature transmission and the like. At the same time, the method comprises the steps of, it also needs to have the characteristics of high temperature resistance, wear resistance, replaceability and the like, so as to meet the requirements of the production process. The traction long roller is contacted with the high-temperature glass plate, and applies proper force to draw and stretch the glass liquid into continuous glass sheets; the glass plate can be stably supported and fixed, the problems of shaking, deformation or breakage and the like in the traction process are prevented, and the quality stability of the glass plate is ensured; because the substrate glass production process is usually carried out under high temperature conditions, the traction long roller needs to have certain heat conducting property so as to rapidly remove heat from the glass sheet and realize rapid cooling and solidification; the traction long roller has the characteristics of high temperature resistance and abrasion resistance, can adapt to the high-temperature working environment and the friction effect of glass liquid on the surface of the traction long roller, and can maintain the long service life.

However, conventional pulling rolls have some problems during use. Firstly, because the characteristic of high temperature molten glass liquid, pull the long roller and work under the high temperature, and under this kind of condition, traditional pull long roller can appear undulantly in the use of glass liquid feed temperature, lead to the thickness of glass board to change, lead to the extrusion to the long roller of pull of both sides, the protective structure in the roller outside is less with annealing furnace terminal surface contact surface, the weight of counter weight is less simultaneously, it is infirm to fix, and then lead to can't carrying out steady support, the roller produces and rocks, and then the roller rocks or warp at the in-process production of drawing base plate glass, reverse acting on base plate glass, produce harmful effects to base plate glass's quality.

Secondly, traditional annealing stove structure is integral type structure, and the tip face is fixed on the furnace body, has the slotted hole on the tip board, and the outside major axis of traction roller stretches out from the slotted hole, and the traction roller is wholly installed inside the furnace body, if the installation of carrying out the roll body is changed, needs all to demolish the end plate, receives furnace body structure's restriction, and this kind of change mode wastes time and energy, and has the potential safety hazard, can also prolong production line downtime simultaneously, causes negative effect to production efficiency and output.
