Embodiment 1

[0027] The sintering method of the present invention comprises the following steps:

[0028] Step 1: Make the DM-308 glass powder type glass blank Inner diameter = 11.2mm, The outer diameter = 14.5mm is evenly stacked on the metal plate made of 310S, the concentric circular surface of the glass blank is in contact with the surface of the metal plate, and the glass blank is in the shape of a ring;

[0029] Step 2: Set the temperature t1=690°C and the speed r1=240 rpm of the chain-type sintering furnace;

[0030] Step 3: Flow the metal plate into the chain-type sintering furnace with the chain to shape the glass blank once. In order to make the sintered glass blank plastic, the glass blank can be picked up and inserted into the ceramic tube without breaking. The inner diameter Φ1=10 mm of the glass blank at this time was measured.

[0031] Step 4: Selection of ceramic tube: Select the ceramic tube according to the Φ1=10mm of the glass blank obtained in step 3 and the inner ...

Embodiment 2

[0042] The sintering method of the present invention comprises the following steps:

[0043] Step 1: Make the DM-305 glass powder type glass blank Inner diameter = 11.2mm, The outer diameter = 14.5mm is evenly stacked on the metal plate made of 310S, the concentric circular surface of the glass blank is in contact with the surface of the metal plate, and the glass blank is in the shape of a ring;

[0044] Step 2: Set the temperature t1=700°C and the speed r1=230 rpm of the chain-type sintering furnace;

[0045] Step 3: Flow the metal plate into the chain-type sintering furnace with the chain to shape the glass blank once. In order to make the sintered glass blank plastic, the glass blank can be picked up and inserted into the ceramic tube without breaking. The inner diameter Φ1=10 mm of the glass blank at this time was measured.

[0046] Step 4: Selection of ceramic tube: Select the ceramic tube according to the Φ1=10mm of the glass blank obtained in step 3 and the inner ...

Embodiment 3

[0057] The sintering method of the present invention comprises the following steps:

[0058] Step 1: Make the produced BDG-4 glass powder type glass blank Inner diameter = 11.2mm, The outer diameter = 14.5mm is evenly stacked on the metal plate made of 310S, the concentric circular surface of the glass blank is in contact with the surface of the metal plate, and the glass blank is in the shape of a ring;

[0059] Step 2: Set the temperature t1=660°C and the speed r1=220 rpm of the chain-type sintering furnace;

[0060] Step 3: Flow the metal plate into the chain-type sintering furnace with the chain to shape the glass blank once. In order to make the sintered glass blank plastic, the glass blank can be picked up and inserted into the ceramic tube without breaking. The inner diameter Φ1=10 mm of the glass blank at this time was measured.

[0061] Step 4: Selection of ceramic tube: Select the ceramic tube according to the Φ1=10mm of the glass blank obtained in step 3 and th...

Abstract

The invention belongs to the technical field of glass sintering, and particularly relates to a sintering method of a glass insulator. The method is as follows: a glass biscuit is subjected to one-time setting and multi-time ceramic tube sintering to obtain a finished glass blank. The sintering method disclosed by the invention has the beneficial effects that sintering without deformation of a large-size glass biscuit is realized, and shape and position tolerance dimensions of the glass biscuit with a thin wall of which the inner diameter phi is greater than 10mm and the wall thickness is less than 2mm is particularly kept unchanged.

Description

technical field [0001] The invention belongs to the technical field of glass sintering, and in particular relates to a sintering method of a glass insulator. Background technique [0002] Glass insulators have the following characteristics: 1. High mechanical strength, 1 to 2 times higher than that of porcelain insulators; 2. Stable performance, not easy to age, and higher electrical performance than porcelain insulators; 3. Less production processes, short production cycle, and easy mechanization , automatic production, high production efficiency; 4, due to the transparency of glass insulators, it is easy to find small cracks and various internal defects or damage during external inspection; 5, if the glass body of the insulator has various defects, the glass The main body will break automatically, which is called "self-breaking". After the insulator breaks itself, the iron cap residual hammer still maintains a certain mechanical strength and hangs on the line, and the lin...
