Problems solved by technology

[0004] The firing method used in conjunction with the green body formula is also a subject of research by many manufacturers. With a better green body formula, there must be a firing method suitable for this green body formula. Practice has proved that there is no heating curve for firing ( firing method) is suitable for all green bodies, or the effect is good, and no green body is suitable for multiple firing methods; if the green body does not match the firing method, there will be wind shock in the product, or serious deformation, or Disadvantages of wasting energy, or foaming, affecting product quality

Embodiment 1

[0054] Select a dry green body, the maximum wall thickness of the green body is 3 cm.

[0055] The main shape of the high-voltage electric porcelain is as follows: the inside is a hollow cylinder, and the outside of the cylinder is the shed. The maximum thickness is the thickness of the shed or the wall thickness of the hollow cylinder. The maximum thickness is 3 cm is basically a thinner thickness in the electric porcelain industry, that is to say, this green body belongs to a smaller shape of electric porcelain.

[0072] a. From room temperature to 120 degrees, evenly heat up for 120 minutes;

[0073] b. From 120 degrees to 200 degrees, the temperature is raised evenly for 380 minutes;

[0074] c. From 200 degrees to 300 degrees, evenly heat up for 320 minutes;

[0075] d. From 300 degrees to 600 degrees, the average temperature rises for 620 minutes;

[0076] e. From 600 degrees to 950 degrees, the temperature is raised evenly for 620 minutes;

[0077] f. From 950 degrees to 960 degrees, keep warm and heat up for 500 minutes;

[0078] g. From 950 degrees to 1060 degrees, evenly heat up for 380 minutes;

[0079] h. From 1060 degrees to 1220 degrees, the temperature is raised evenly for 440 minutes;

[0080] i. From 1220 degrees to 1220 degrees, keep warm for 200 minutes;

Embodiment 3

[0085] Select a dry green body, the maximum wall thickness of the green body is 3 cm.

[0086] Burn according to the following method:

[0087] a. From room temperature to 120 degrees, evenly heat up for 110 minutes;

[0088] b. From 120 degrees to 200 degrees, the temperature is raised evenly for 360 minutes;

Abstract

The invention relates to the technical field of electric porcelain production, and particularly relates to a high-voltage electric porcelain sintering method. The high-voltage electric porcelain sintering method comprises the steps of loading green bodies and enabling the green bodies to enter a kiln and is characterized in that the green body sintering process comprises the following steps: step a. uniformly heating for 100-120 minutes from a normal temperature to 120 DEG C; step b. uniformly heating for 340-380 minutes from 120 DEG C to 200 DEG C; step c. uniformly heating for 280-320 minutes from 200 DEG C to 300 DEG C; step d. uniformly heating for 580-620 minutes from 300 DEG C to 600 DEG C; and step e. uniformly heating for 580-620 minutes from 600 DEG C to 950 DEG C, and the like, and sintering high-voltage electric porcelain. The high-voltage electric porcelain has the advantages of insulation, weather fastness, excellent arc flashing resistance, low cracking rate, low water absorption, low cost and good luminance.

Description

technical field [0001] The invention relates to the technical field of electric porcelain production, in particular to a firing method for high-voltage electric porcelain. Background technique [0002] The production of high-voltage electric porcelain has a long history, and there are many manufacturers. Various manufacturers and research institutes have developed many green body formulas and firing methods. These green body formulas and firing methods have produced many high-quality high-voltage electric porcelain. These high-voltage electric ceramics play a huge role in national construction; but on the one hand, after a long period of development and utilization of some raw materials, resources are facing exhaustion, resulting in higher prices of raw materials and higher production costs, which cannot meet the needs of actual production; on the other hand The advancement of technology requires higher performance and high-strength electric porcelain, for example, it is bet...
