Float glass forming cooling water packet
A technology of float glass and cooling water, which is applied in the direction of glass production, etc. It can solve the problems of uneven lateral cooling effect, affecting the stability of working conditions, and large thickness deviation, so as to reduce the difference in glass thickness, increase the yield, and reduce the size of the glass. The effect of lateral temperature difference

[0002] The original cooling water bag of the tin bath in the float process is basically a three-tube straight plate or gap water bag. During the cooling process, due to the relatively good cooling effect of the water entering the edge and the natural temperature difference in the tin bath, the edge of the glass plate and the middle of the plate are caused. The thickness deviation is obviously large (take the eight-wire thick glass as an example, the edge of the glass plate is thinner and the middle is thicker after being subjected to the force of the edge pulling machine); The thickness of the glass is different. Generally, the electric heating at the edge of the tin tank is used to balance the effect of the lateral temperature difference of the glass, which not only affects the stability of the working conditions in the tank, but also causes energy waste.

Embodiment
[0013] Embodiment: An 80cm length stainless steel active sleeve 2 is installed outside the cooling water bag body 1 in the high temperature zone of the tin bath, and the fiber asbestos insulation board 4 is tightly plugged between the active sleeve 2 and the water bag body 1, and then the active Sleeve 2 and fiber asbestos insulation board 4 are moved as a whole to the position where the cooling water bag extends into the tin tank and is 40mm away from the wide side of the tin tank, and then fixed with bolts 3, so as to achieve local heat preservation effect and balance the water bag The horizontal cooling temperature reduces the temperature difference between the edge and the plate during the forming process of the tin bath of the glass plate, and reduces the overall thickness difference of the glass. Wherein the water bag body 1 is a water bag square tube, and the flexible sleeve 2 is a stainless steel rectangle;

The invention discloses a float glass forming cooling water packet which comprises a water packet body and a segmental sleeve, wherein the segmental sleeve is sleeved at any position of the water packet body; and an insulation plate is filled between the segmental sleeve and the water packet body, the segmental sleeve, the water packet body and the insulation plate are fixedly connected through bolts. The float glass forming cooling water packet has the advantages that the segmental sleeve is arranged on the cooling water packet body, so that in the glass forming process, transverse temperature difference can be artificially shortened, the thickness difference of the glass is reduced, and yield is improved; and simultaneously, the segmental sleeve has a low manufacturing cost and an obvious effect, the position of the sleeve can be regulated at any time according to the temperature variation in a groove, and operation is convenient.
