Description
Technical Field
The invention belongs to the technical field of float glass production process equipment, and relates to a glass belt cooling device of a float glass tin bath.
Background
The float glass forming temperature is typically in the range of 1100 to 600 c. In the forming process, the glass is required to be subjected to four forming process stages of high-temperature natural flattening and polishing, drawing and forming of the glass by forming equipment, slow cooling and shaping of the glass, and reinforced cooling of the glass by water cooling equipment, so that the forming process of the float glass can be completed completely. The fourth stage in the float glass forming process, namely the stage of cooling the glass by water cooling equipment, is a key region of entering the reinforced cooling and finally leaving the tin bath at 600 ℃ after the float glass is formed and shaped.
According to the heat dissipation and heat transfer principles of glass in a tin bath, the larger the glass yield is, the thinner the produced glass is, the higher the temperature of the glass in the fourth stage of the forming process in the tin bath is, the more difficult the cooling is, and the length of the tin bath must be lengthened to meet the process requirements. The tin bath is composed of a brick structure, a steel structure and noble metal tin liquor, and the design of the length of the tin bath is increased, so that the investment of the tin bath is greatly increased. In order to reduce the production cost of float glass and reduce the increase of investment cost caused by the lengthening of a tin bath or the increase of tin liquor, the number of water drum coolers in the space of the tin bath is increased in the fourth stage on the premise of meeting the basic forming and shaping process requirements of the first three stages of the float glass in the actual production process, so that the design of reducing the length of the tin bath is realized, and the purpose that the float glass subjected to intensified cooling can finally leave the tin bath at the process temperature of 600 ℃ is achieved.
However, in actual production use, after the number of the water drum coolers is increased in the tin bath space, the following problems exist in use:
1. because the water drum coolers are arranged too densely in the tin bath, each group is a row-type space water drum which is formed by 6-8 square tubes and has the width of about 500mm longitudinally and transversely opposite to each other, and a support frame or a floor trolley with larger volume is required to be arranged at the outer side of the tin bath to support the water drum. On one hand, the operation space for handling abnormal accidents of the tin bath is reduced, and the production safety of the tin bath is lowered; on the other hand, too intensively strengthening the radiation cooling glass surface can generate excessive temperature difference in terms of glass thickness, thereby generating glass stress which is difficult to eliminate in the subsequent annealing stage, not only affecting the flatness of the glass, but also seriously damaging the on-line annealing and cutting quality of the glass and reducing the glass yield.
2. As the molten tin in the tin bath is an active substance, after being oxidized by oxygen and S02 which are permeated by the outside, the molten tin can generate oxides with extremely high volatility, and in severe cases, the volatile substances are easy to deposit and condense on the surface of the space water drum cooler of the tin bath after being cooled, and after reaching a certain degree, the volatile substances are influenced by complex redox atmospheres (N2, H2, O2 and SO 2) and air currents in the tin bath, and flocculent or tin drop-mixed particles fall onto the surface of glass to form optical deformation of the surface of the glass, tin spots on the surface of the glass, tin polluted sundries and the like, SO that the quantity of glass defective products is increased.
