Description
Technical Field
The utility model belongs to the technical field of float glass production facility, concretely relates to a draw limit wheel that is used for float glass draws limit machine.
Background
The float glass is produced by a float forming process, and the edge roller is mainly used for drawing a glass belt from two sides of the glass belt at a certain angle in the production process, spreading the glass belt to a certain thickness, then guiding the glass belt into an annealing kiln through a transition roller for annealing, cutting, and finally packaging finished products.
In this production process, the edge roller on the edge roller works for a long time in the molten tin bath or the broken glass plates appear in production, the full groove emergency accident, lead to the edge roller not in time to lift up, in the edge roller gets into the molten tin, can be full of tin between the edge roller tooth, weaken the glass plate effort, can not effectively stabilize the glass plate and draw thin shaping, must pull out the molten tin bath to the edge roller, clean edge roller, sweep the edge roller head through oxygen acetylene, steel brush clean-up just can continue to use, influence production efficiency.
In addition, the metal edge roller is worn and aged easily after contacting with the glass plate for a long time, so that the acting force of the edge roller is weakened, the trend and the width of the glass plate cannot be controlled, adhesion with the glass plate can be caused, and finally the rolling machine head cannot be stably produced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a draw limit wheel for in float glass draws limit machine can realize drawing the limit wheel and not invading moist with tin liquid, increases the intensity, the hardness that draw the limit wheel, improves production efficiency.
The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be: a draw limit wheel for in float glass draws limit machine, includes draws the limit wheel body, the surface of drawing the limit wheel body has plated NiCrAlY layer, transition layer, CeO in proper order from bottom to top2 -Y2O3 -ZrO2And (3) a layer.
Further, the thickness of the NiCrAlY layer is 0.08-0.1 mm.
Further, the thickness of the transition layer is 0.04-0.06 mm.
Further, the CeO2 -Y2O3 -ZrO2The thickness of the layer is 0.1-0.15 mm.
Further, the transition layer is NiCrAlY and CeO2 -Y2O3 -ZrO2The mixed layer of (1).
The utility model discloses the beneficial effect who brings:
1. the utility model adopts the metal bottom NiCrAlY to eliminate the residual stress caused by spraying and improve the bonding capability of the coating; the intermediate transition layer reduces the difference in thermal expansion between the metal and the ceramic and improves the stress distribution in the coating.
2. CeO is adopted as the outer surface layer2 -Y2O3 -ZrO2The edge roller has the advantages that the strength and hardness of the edge roller are increased, the wear resistance and corrosion resistance of the edge roller are enhanced, the edge roller can run in a tin bath for a long time and is not soaked with tin liquid, the width and thickness of a plate are convenient to control, the production stability is ensured, and the production efficiency is improved; in addition, CeO2 -Y2O3 -ZrO2The high heat insulation of the layer can reduce the temperature rise of the edge roller and reduce the deformation.
3. Compare with graphite material edge roller, the utility model discloses an edge roller is more stand wear and tear, is favorable to prolonging edge roller life.
4. Compare with ceramic material edge roller, the utility model discloses an edge roller is able to bear or endure the rapid cooling, and difficult fracture can use for a long time.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, edge roller, 2, NiCrAlY layer, 3, transition layer, 4, CeO2 -Y2O3 -ZrO2And (3) a layer.
Detailed Description
The present invention will be described in further detail with reference to the drawings and specific examples.
As shown in figure 1, the edge roller for the float glass edge roller comprises an edge roller 1 bodyThe outer surface of the edge roller 1 body is sequentially plated with a NiCrAlY layer 2, a transition layer 3 and CeO from bottom to top2 -Y2O3 -ZrO2A layer 4; the thickness of the NiCrAlY layer 2 is 0.08-0.1mm, the thickness of the transition layer 3 is 0.04-0.06mm, and the CeO2 -Y2O3 -ZrO2The thickness of the layer 4 is 0.1-0.15mm, and the transition layer 3 is NiCrAlY and CeO2 -Y2O3 -ZrO2The mixed layer of (a) is specifically: the above-mentioned NiCrAlY and CeO2 -Y2O3 -ZrO2The coating material is prior art and is easily manufactured by those skilled in the art.
The working process is as follows: cleaning the outer surface of the edge roller, and spraying the NiCrAlY layer 2 on the outer surface of the edge roller by adopting an atmospheric plasma spraying technology, wherein the NiCrAlY layer 2 eliminates residual stress caused by spraying, so that the bonding capability of the coating is improved; then the transition layer 3 is sprayed on the NiCrAlY layer 2, the transition layer 3 reduces the thermal expansion difference between metal and ceramic, and improves the stress distribution in the coating; finally spraying CeO2 -Y2O3 -ZrO2Layer 4, CeO2 -Y2O3 -ZrO2Layer 4 reduces the temperature rise of drawing the limit wheel, reduces and warp, has increased the intensity, the hardness of drawing the limit wheel, has strengthened the stand wear and tear, the corrosion resisting property of drawing the limit wheel, has guaranteed to draw the limit wheel can long-time operation in the molten tin bath, and does not invade the moist with the tin liquor, and the control board width of being convenient for is thick with the board, guarantees production stability, improves production efficiency, is fit for large-scale production.
It should be noted that the above embodiments are only used for illustrating the present invention, but the present invention is not limited to the above embodiments, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention all fall into the protection scope of the present invention.
