Kiln vehicle corner column brick and vehicle loading method for porcelain bushing blank bodies

Abstract

The invention relates to a kiln vehicle corner column brick and a vehicle loading method for porcelain bushing blank bodies. The kiln vehicle corner column brick comprises a brick body, wherein grooves in the same direction are formed on two adjacent surfaces of the brick body. The vehicle loading method comprises the following steps of: a, building columns at four corners of a kiln vehicle by using the kiln vehicle corner column brick; b, placing the blank bodies on the kiln vehicle regularly, and ensuring that each column occupies the position of one blank body; and c, pressing the tops of the two adjacent blank bodies by using a pressure head plate, and pressing outer sides of four peripheral blank bodies on the kiln vehicle by using a beam, wherein the beam has a square pipe structure made of silicon carbide, and two end parts of the beam are arranged in the grooves of the kiln vehicle corner column brick. Compared with the prior art, the kiln vehicle corner column brick has the advantages that: the beam glides vertically due to contraction in the process of sintering the blank bodies, so that the blank bodies are pressed uniformly; and space is saved, the capacity is improved, an operation process is simplified, and porcelain bodies are solider.

Description

technical field [0001] The invention relates to the technical field of high-voltage electric porcelain firing, in particular to a method for loading kiln car corner column bricks and porcelain sleeve blanks. Background technique [0002] The individual of high-voltage electric porcelain is relatively long, and it is easy to bend and deform during the firing process of the green body. In the prior art, the method of hoisting and firing is adopted, that is, multiple pillars are installed on the kiln car, and there are hanging pillars between the upper parts of the pillars. There is a hanging plate between the beam and the hanging beam. The hanging plate has a through hole that clamps the neck of the porcelain sleeve. During the firing process, the green body shrinks, and the hanging plate prevents the deformation of the porcelain sleeve. Such loading and firing The method has the disadvantages that there are many columns, the utilization rate of the kiln car is small, and the ...

[0002] The individual of high-voltage electric porcelain is relatively long, and it is easy to bend and deform during the firing process of the green body. In the prior art, the method of hoisting and firing is adopted, that is, multiple pillars are installed on the kiln car, and there are hanging pillars between the upper parts of the pillars. There is a hanging plate between the beam and the hanging beam. The hanging plate has a through hole that clamps the neck of the porcelain sleeve. During the firing process, the green body shrinks, and the hanging plate prevents the deformation of the porcelain sleeve. Such loading and firing The method has the disadvantages that there are many columns, the utilization rate of the kiln car is small, and the green body needs to reserve a hanging neck to waste raw materials. When firing, the green body is hoisted to reduce the density of the porcelain sleeve, which also reduces the strength of the porcelain sleeve. In addition, it also has the disadvantages of low production efficiency and complicated process.
