Detailed Description
Further advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present invention, which is described by the following specific examples.
It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for the purpose of understanding and reading the disclosure, and are not intended to limit the scope of the invention, which is defined by the appended claims, but rather by the claims, unless otherwise indicated, and unless otherwise indicated, all changes in structure, proportions, or otherwise, used by those skilled in the art, are included in the spirit and scope of the invention. Also, the terms such as "upper," "lower," "left," "right," "middle," and "a" and the like recited in the present specification are merely for descriptive purposes and are not intended to limit the scope of the invention, but are intended to provide relative positional changes or modifications without materially altering the technical context in which the invention may be practiced.
As shown in fig. 1, the present invention provides a tin bath, comprising:
a molten tin bath bottom which is built by molten tin bath bottom bricks 4; the material of the tin bath bottom brick is generally clay or calcium aluminate;
tin bath side walls with composite graphite lining.
The composite graphite lining is composed of two detachable and spliced graphite lining parts, so that even if the graphite lining leaked from tin liquor is oxidized or falls off, one of the graphite lining parts can be replaced conveniently, and accordingly maintenance cost is reduced greatly.
Specifically, in order to make the tin bath side wall with the composite graphite lining replace one of the graphite lining parts conveniently, in combination with fig. 1 and 2, the tin bath side wall with the composite graphite lining includes:
the side wall brick 3, the inside wall of the side wall brick 3 is provided with an L-shaped lining embedded groove, and the lining embedded groove comprises a vertical groove part and a horizontal groove part vertically communicated with the bottom end of the vertical groove part;
the lining assembly comprises a fixed lining 7, a filling type lining 8 and a compression bar 9, wherein the fixed lining 7 and the filling type lining 8 are made of graphite materials, the cross section of the fixed lining 7 is L-shaped, the cross section of the filling type lining 8 is rectangular, the fixed lining 7 comprises a vertical lining part and a horizontal lining part which is vertically connected to the bottom end of the vertical lining part, the horizontal lining part of the fixed lining 7 is clamped on the horizontal groove part of the embedded groove of the lining, the vertical lining part of the fixed lining 7 is clamped on the vertical groove part of the embedded groove of the lining, and a gap area is reserved for the filling type lining 8, and the filling type lining 8 is installed on the side wall brick 3 through the compression bar 9 to fill the gap area.
In the invention, the side wall brick 3 is also made of clay or calcium aluminate, the fixed lining 7 and the filling type lining 8 are made of high-purity high-carbon graphite, and the pressing rod 9 is made of heat-resistant steel. The molten tin is filled in a tank surrounded by the bottom bricks and the side wall bricks. The glass ribbon floats on molten tin and is spread out, and is formed under the action of an edge roller. The side wall brick is provided with an embedded groove (called L-shaped groove for short) of the L-shaped lining, the fixed lining 7 is embedded in the side wall brick, and the L-shaped space formed by the tin bath bottom brick and the side wall brick enables the fixed lining 7 to float away under the buoyancy and convection of tin liquid, so that the side wall brick can be stably embedded in the side wall brick. It should be noted that the installation of the graphite lining structure needs to be performed synchronously with the construction of the side wall bricks, otherwise, after the side wall bricks are closed, the fixed lining 7 cannot be installed. When the glass ribbon 1 is wide to the side wall brick, the filling type lining 8 and/or the fixed type lining 7 block the glass ribbon 1, the glass ribbon 1 and the graphite lining are not soaked and can not adhere, and the glass ribbon and the graphite lining can be easily separated by adjusting the edge roller or other auxiliary means, so that the occurrence of full-groove accidents is avoided.
In the long-term production process, the top of the existing integral graphite lining is gradually oxidized due to frequent exposure to the space, and graphite materials at the top of the existing integral graphite lining gradually fall off and are lost. When the glass band width reaches the side wall brick, the glass band can not be blocked by the existing integrated graphite lining, the glass band is contacted and adhered with the side wall brick, accidents are easy to occur, and the structure of the existing integrated graphite lining determines that the existing integrated graphite lining is difficult to take out and replace in a thermal state. Based on this, the composite graphite lining structure of the present invention solves this problem. When the filled lining 8 in the tin bath is oxidized and the material is gradually dropped and damaged, a new filled lining 8 is assembled in advance in a cold state, the filled lining 8 and the compression bar are connected for standby through a connecting piece, then the assembled filled lining 8 is placed in the tin bath in a hot state, and the compression bar is fixed on the side wall brick 3 after the position is fixed. The filling type lining 8 is pressed on the fixed lining 7 to fill the vacant area again, and when the glass ribbon 1 is wide to the side wall brick, the filling type lining 8 can block the glass ribbon 1 again, so that the glass ribbon 1 is prevented from being contacted with the side wall brick.
Therefore, the tin bath side wall with the composite graphite lining greatly reduces the lining maintenance cost of the tin bath side wall by utilizing the split design of the fixed lining 7 and the filling type lining 8, so that the tin bath graphite lining can meet the requirement of long-term production safety guarantee.
