Description
Technical Field
The invention belongs to the technical field of glass plate production, and particularly relates to a control device and a control method for a warping defect of plate glass.
Background
In the glass production process, float glass is formed in a tin bath from molten glass and then enters an annealing furnace for annealing. The glass is cooled down in the lehr over a sufficient period of time, either through the annealing temperature range or at a slow rate, to minimize or eliminate thermal stresses generated in the glass. In the annealing process, the temperature difference between the upper surface and the lower surface of the glass plate is larger, or the temperature difference between the transverse direction of the glass plate is larger, so that the warping defect of the glass is generated. The generation of glass warping defect not only affects the yield of glass, but also can generate production safety accidents under the circumstance of serious warping.
The warpage is classified into permanent warpage and temporary warpage, and both permanent warpage and temporary warpage are caused by the fact that a temperature difference exists between the upper surface and the lower surface of the glass plate or in the width direction of the glass plate in the annealing and cooling processes of the glass plate, so that the cooling strength and the center of the two sides of the glass plate are inconsistent, or the cooling strength of the upper surface and the lower surface of the glass plate is inconsistent, and permanent stress or temporary stress is unevenly distributed. In the prior art, when the glass plate has a warping defect, the glass plate can be cut and sampled only after annealing, and then the glass plate is detected and judged by using off-line special warping detection equipment. If the glass plate is warped, the process technician judges the position of the glass plate, which possibly has inconsistent temperature, in the annealing process of the annealing kiln according to the position of the warped glass plate, then carries out annealing temperature adjustment of the relevant area, then carries out sampling detection, and repeats the process until the problem of warping defects is solved. The method for solving the warp defect of the glass plate has the following problems: 1. the duration of the warping defect is long, and sampling detection can only be carried out after the glass plate is offline; 2. judging that the warpage of the glass plate 3 has a temperature inconsistent part in the annealing kiln requires experience of technicians, and different process technicians may have different judging results.
