Description
The technical field is as follows:
the invention relates to the field of float glass production, in particular to a graphite isolating device for a float glass forming process.
Background art:
the float process is a method for forming plate glass on the surface of molten metal tin after the molten glass in melting furnace flows into tin bath, the tin bath is key thermal equipment for float glass forming, the tin bath is loaded with tin liquor, the molten glass is floated on the surface of tin liquor, under the control of proper temperature gradient, under the action of edge-drawing machine, the plate glass with required thickness and width can be formed. After the glass plate is shaped, the glass plate is required to be led out to a transition roller at the tail end of a tin bath and is continuously sent to an annealing kiln.
The molten tin bath body is a closed device consisting of refractory materials and steel plates, and because molten glass and the refractory materials belong to inorganic oxide materials, wettability exists between the molten glass and the refractory materials, when the molten glass is in contact with the refractory materials, adhesion can be caused, so that the production process is influenced, the molten glass is prevented from adhering to the wall of the molten tin bath, graphite materials are lined on the inner side of the wall of the molten tin bath generally, graphite is not soaked with the molten tin and the molten glass, and a good isolation effect can be achieved.
Because the tin liquid height can be adjusted because of the technology needs, also can cause the altitude variation because of tin liquid consumption, therefore graphite is made rectangular form usually, and has certain degree of depth below the tin liquid level, because graphite proportion is little than the tin liquid much, therefore the graphite inside lining can receive great buoyancy, generally adopts the steel sheet band screw to fix the graphite strip inboard at the pool wall, but this kind of connected mode has following shortcoming:
1. the graphite strip is well installed in a cold state, and because the expansion coefficient difference between graphite and the screw is large, the graphite is about 220E-6/k while the expansion coefficient of steel is about 12E-6/k, and the screw is loosened and is not firmly fixed when the temperature is increased to a high temperature.
2. When the forming lead or the abnormity occurs, the tin bath edge seal is usually required to be opened, the glass plate is manually operated by tools such as a hook shovel, the graphite strip can be pressed by the tools such as the hook, and the graphite strip is easy to press and fall off.
3. Graphite is used for a long time at high temperature, slow burning loss is generated, screw holes are enlarged, and screws are loosened.
4. When the graphite strip drops because some reason, when needing to be changed, because the steel clamp plate welding needs to cut open on the cell body shell steel construction, after changing new graphite strip, need keep operating condition to descend and press a welding to resume, work load is big, the operation degree of difficulty is high, and operational environment is abominable.
5. Cold installation and disposable. Once the graphite strip is burnt, the graphite strip cannot be repaired.
6. And the device is installed in a cold state, and is easy to loosen and fall off after being heated. After long-term use, the material may loosen and fall off due to burning loss.
The invention content is as follows:
the invention aims to overcome the defects in the prior art and provides the graphite isolating device for the float glass forming process.
The application provides the following technical scheme:
the utility model provides a graphite isolating device for float glass forming process, it includes that brick at the bottom of molten tin bath lateral wall brick and molten tin bath, is equipped with the mounting groove on the brick at the bottom of the molten tin bath that is close to molten tin bath lateral wall brick, is equipped with graphite inside lining, its characterized in that in the mounting groove: the tin bath side wall brick is provided with a sliding groove, one side of the graphite lining is provided with a sliding block clamped into the sliding groove, the outer side of the tin bath side wall brick is provided with an outer wall, the outer wall is provided with an inserting ring, and a pressing rod correspondingly matched with the graphite lining is inserted into the inserting ring.
On the basis of the technical scheme, the following further technical scheme can be provided:
the sliding groove is a dovetail groove or a T-shaped groove, the sliding blocks are longitudinally distributed along the graphite lining, and the section of the sliding block is in a dovetail shape or a T shape.
The invention has the advantages that:
the graphite lining replacing device has the advantages of simple structure, flexible operation, quick replacement of the graphite lining, better use effect and the like. Especially, the bottom end of the graphite lining can not float away after being separated from the mounting groove due to the design of the sliding groove and the sliding block.
