Float glass lift-up roller station and method for introducing glass head into float glass lift-up roller station for first time

Abstract

The invention provides a float glass lift-up roller station and a method for introducing a glass head into the float glass lift-up roller station for the first time. The float glass lift-up roller station is located between a tin bath and an annealing furnace and comprises a discharged slag box, tin cleaning devices, rollers, a transmission device of the rollers, electric heating devices, an upper cover, a sealing check curtain and sealing check curtain adjusting mechanisms sequentially from bottom to top, wherein the discharged slag box is an open type and is separated from the tin cleaning devices, so that maintenance of the tin cleaning devices and replacement of the rollers above the discharged slag box are facilitated; the electric heating devices which are located above the rollers and are in sleeve connection with the upper cover facilitate temperature adjustment of the lift-up roller station; tin cleaning adjusting devices arranged in the tin cleaning devices adjust gaps between graphite blocks and the rollers through relative sliding of upper wedge blocks and lower wedge blocks, the structure is simple and not prone to deformation, and accordingly, the tin cleaning effect and sealing effect of the tin cleaning devices are enhanced. The device and the method fit in with float glass production, can improve the quality of glassware and are easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of float glass manufacturing, and relates to transition roll table technology, in particular to a float glass transition roll table and a method for introducing glass heads into it for the first time. Background technique [0002] The float glass transition roller table is the key equipment between the tin bath equipment and the annealing furnace, which belongs to the continuation of the end of the tin bath equipment. Its main function is to lead the glass ribbon at about 600°C from the tin bath to the annealing kiln. Is its structure Whether it is reasonable and whether the sealing is tight is related to the increase of the internal pressure of the tin bath and the stability of the production of the tin bath, which directly affects the production quality of float glass. In the current technology, the rollers of the transition roller table usually operate at a high temperature above 600°C, and most of the ro...

Problems solved by technology

The leaf spring gradually deflects in a temperature environment of 600°C, generally about 20-25mm; at the same time, the bridge structure and the roller itself also deflect, and the deflection generated by the roller exerts pressure on the graphite block, causing the graphite block structure to deform. Therefore, the tin wiping device is prone to stepping on the waist at high temperature, resulting in that the tin wiping device cannot be in close contact with the roller, and the tin and its oxides on the roller cannot be wiped off, nor can it play a good sealing role.

[0004] The existing transition roller table is usually connected to the lower slag box, the curtain, etc., the space is large and the heat preservation conditions are not good. When the glass ribbon enters the transition roller table from the tin tank, the temperature will drop, which is very unfavorable to the formation of the annealing stress of the glass and affects the cutting of the glass. Yield rate, resulting in poor flatness
