Problems solved by technology
In this pouring method, the crucible or matrix glass filled with high-temperature molten glass must be moved smoothly during the pouring process. The operation can only be completed by taking it out of the middle, and the risk of glass bursting due to the impact of cold air is very high

Embodiment Construction
[0032] The glass hard edging pouring cover of the present invention is as Figure 3-4 As shown, the main body 3 of the pouring cover made of graphite or metal material (bronze, cast iron, etc.) is provided with a groove 4 at the center of the upper end of the main body 3 of the pouring cover. The groove 4 is preferably a cylindrical structure with a diameter of 60 mm or more. 4 is the center and extends outwards to provide a number of flow grooves 5. One end of the flow groove 5 is connected to the groove 4, and the other end extends to the edge of the main body 3 of the pouring cover. upper end.
[0033] In order to ensure the smooth flow of the edge-encapsulated glass, the width of the flow tank 5 is preferably more than 20mm, and the flow tank 5 is arranged obliquely. High, the bottom of the liquid flow tank 5 and the pouring cover main body 5 preferably forms an inclination angle of more than 5°.
[0034] The inventive method preferably also adopts the diversion groove 6...

The invention provides a glass hard clad edge cast cover which is uniformly cast and ensures that glass is not easy to explode and a casting method thereof. The cast cover comprises a cast cover main body, wherein a groove is formed in the center of the upper end of the cast cover body; a plurality of solution flowing grooves extend outwards by taking the groove as a center; one end of each solution flowing groove is communicated with the groove, and the other end extends to the edge of the cast cover main body. As edge-cladding glass solution uniformly flows from the center of the cast cover to the periphery, the edge-cladding glass solution flowing to all positions of the gap between matrix glass and a die does not have temperature difference, and a container filled with a high-temperature molten glass solution is not required to be shifted, the problems that molten edge-cladding glass cast method is not uniform in hard clad edge casting and the glass is easy to explode are solved.
Description
technical field [0001] The invention relates to a glass edging device and a method thereof, in particular to a laser glass hard edging pouring cover and a pouring method thereof. [0002] technical background [0003] Laser glass edging is one of the three major components of the laser glass development process. In the encapsulation, the refractive index matching of the laser glass and the encapsulation glass plays a crucial role in the residual reflection, which will eventually affect the degree of suppression of parasitic oscillations, thereby affecting the gain of the amplifier. At present, laser glass edging methods are generally divided into two types: [0004] One is to use optical adhesive to paste the edge glass that absorbs parasitic oscillation amplified spontaneous emission (ASE) around the base laser glass, and optimize the chemical composition to make the base laser glass, binder material and ASE-absorbing cladding physically Match the properties as much as pos...
