Embodiment 1

[0020] A high-temperature glass welding process, comprising the following process steps,

[0021] 1) According to the size and shape requirements of the prepared glass, select a suitable high-temperature glass tube and cut it as the glass body;

[0022] 2) According to the size and shape requirements of the cup body, prepare a cup bottom with a suitable size that matches the cup body. The material used for the cup bottom is the same as that of the cup body and has the same expansion coefficient;

[0023] 3) The bottom of the cup is formed by a mold. After forming, it is placed in an incubator and kept at 40°C for 24 hours. Through the heat preservation treatment, the bottom of the cup can be cracked during welding;

[0024] 4) Slowly raise the temperature of the bottom of the cup after heat preservation to 300°C, and at the same time, slowly raise the temperature of the cup body to 300°C, so that the cup body and the bottom of the cup have the same temperature, which is easy t...

Embodiment 2

[0031] A high-temperature glass welding process, comprising the following process steps,

[0032] 1) According to the size and shape requirements of the prepared glass, select a suitable high-temperature glass tube and cut it as the glass body;

[0033] 2) According to the size and shape requirements of the cup body, prepare a cup bottom with a suitable size that matches the cup body. The material used for the cup bottom is the same as that of the cup body and has the same expansion coefficient;

[0034] 3) The bottom of the cup is formed by a mold. After forming, it is placed in an incubator and kept at 38°C for 22 hours. Through the heat preservation treatment, the bottom of the cup can be cracked during welding;

[0035] 4) Slowly raise the temperature of the cup bottom after heat preservation to 310°C, and at the same time, slowly raise the temperature of the cup body to 310°C, so that the cup body and the cup bottom have the same temperature, which is easy to weld between...

Abstract

The invention discloses a high-temperature glass cup welding process, which is implemented through the following steps of 1) according to the requirements on the size and shape of a prepared glass cup, selecting an appropriate high-temperature glass tube, and cutting the high-temperature glass tube to be taken as a cup body; 2) according to the requirements on the size and shape of the cup body, preparing a cup bottom having an appropriate size and matched with the cup body; 3) carrying out die molding on the cup bottom, and then putting the obtained product into a thermal insulation box to carry out heat preservation for 20-26 hours at a temperature of 35-45 DEG C; 4) slowly heating the cup bottom subjected to heat preservation to 280-320 DEG C, and meanwhile, slowly heating the cup body to 280-320 DEG C, so that the cup body and the cup bottom are the same in temperature; 5) welding the cup body and the cup bottom by coal gas and oxygen, wherein the welding temperature is controlled at 580-620 DEG C; 6) after welding for forming is completed, carrying out annealing treatment on the glass cup, when the temperature is reduced to 35-45 DEG C, carrying out heat preservation for 12-24 hours, and then cooling the glass cup; 7) slowly heating the glass cup subjected to cooling from 0 DEG C to 600 DEG C, and then carrying out annealing treatment on the glass cup; 8) carrying out polishing treatment on the glass cup subjected to stain removal; and 9) after polishing is completed, sealing the glass cup, so that a single-layer glass cup can be prepared, or adding a linear to prepare a double-layer glass cup.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a high-temperature glass welding process. Background technique [0002] Glass is divided into non-oxide glass and oxide glass according to the composition, oxide glass is divided into silicate glass, borate glass, phosphate glass and so on. Silicate glass refers to the basic composition of Si0 2 Glass is a colorless and transparent material with the largest output, the widest range of uses, and the lowest price. Quartz glass is the best among silicate glasses. The raw materials used to manufacture quartz glass are crystal, high-purity quartz sand, or white quartz sand, and its composition is high-purity Si0 2 , the melting temperature is required to be above 1713°C. [0003] Quartz glass has a series of special physical and chemical properties: 1. It has excellent high temperature resistance, and its melting point is similar to that of platinum; 2. The thermal expansi...
