Description

A graphite lining for tin bath

technical field

The utility model relates to a float glass production equipment, in particular to a graphite inner lining for a tin bath.

Background technique

Tin bath is the molding equipment of the float glass production process, which is used to contain high-temperature tin liquid. In order to prevent the high-temperature glass liquid from sticking to the side wall refractory bricks, a graphite lining is set between the side wall bricks and the tin liquid by using the principle that graphite lubrication and high-temperature glass liquid do not infiltrate each other. The existing graphite lining has two kinds of fixed structures; one is the mosaic type of the tank body, as shown in Figure 1, the graphite lining is made into an L shape, and it is placed in the reserved groove on the side wall brick or the bottom brick for positioning. , which makes it inconvenient to replace the graphite lining in a hot state; the second is the pressure rod type, as shown in Figure 2, one end of the heat-resistant steel pressure strip is buckled to the graphite lining, and the other end is welded to the side wall brick of the tin bath , used in a long-term high-temperature environment, the heat-resistant steel bead is easy to anneal and deform, and the heat-resistant steel bead needs to be unsoldered when replacing the graphite lining, so it is inconvenient to replace the graphite lining in a hot state.

Contents of the invention

The purpose of the utility model is to solve the problem of inconvenient replacement of graphite lining in hot state in the prior art, and provide a graphite lining which is easy to assemble and disassemble.

The purpose of this utility model is achieved by the following technical solutions:

A graphite lining for a tin bath, comprising a graphite lining body arranged on the reserved groove of the bottom brick of the tin bath, characterized in that the graphite lining body is provided with a tungsten bar, and the quality of the tungsten bar is the same as that of the graphite lining body The sum is greater than the buoyancy of the tin liquid.

The tungsten bar is L-shaped, and the horizontal section of the L-shaped tungsten bar is placed on the upper end surface of the graphite lining body. One side of the vertical section of the L-shaped tungsten bar is attached to one side of the graphite lining body. The other side of the vertical section of the tin tank is attached to one side of the side wall brick of the tin tank.

The utility model has the beneficial effects of simple structure, convenient assembly and disassembly, convenient maintenance and overhaul, and high safety while reducing the labor intensity of operators.

The utility model will be further described below in conjunction with the description of the accompanying drawings and the embodiments.

Fig. 1 is the embedded graphite liner of prior art;

Fig. 2 is the graphite inner lining of welding press plate type in the prior art.

Fig. 3 is a schematic diagram of the front view of the utility model.

Detailed ways

As shown in Figure 3, a kind of graphite liner for tin bath provided by the utility model includes graphite liner body 3 located on the reserved groove of tin bath bottom brick 1b, which is characterized in that the graphite liner body An L-shaped tungsten bar 2 is provided. The sum of the mass of the L-shaped tungsten bar 2 and the mass of the graphite-lined body 3 is greater than the buoyancy of the tin liquid. The transverse section of the L-shaped tungsten bar 2 is placed on the upper end surface of the graphite-lined body 3. One side of the vertical section of the L-shaped tungsten bar 2 is attached to one side of the graphite lining body 3, and the other side of the vertical section of the L-shaped tungsten bar 2 is attached to one side of the tin bath side wall brick 1a.

Claims (2)

1. for a graphite liner for molten tin bath, comprise the graphite liner body (3) of being located on bottom brick of molten tin bath (1b) preformed groove, it is characterized in that graphite liner body is provided with tungsten rod (2), tungsten rod quality and this weight of graphite liner sum are greater than the buoyancy of tin liquor.

2. a kind of graphite liner for molten tin bath according to claim 1, it is characterized in that tungsten rod (2) is for L-type, the crosspiece of L-type tungsten rod is placed on the upper surface of graphite liner body (3), one side laminating of perpendicular section of side of L-type tungsten rod and graphite liner body (3), perpendicular section of opposite side of L-type tungsten rod fitted with a side of molten tin bath sidewall block (1a).
