Embodiment 1

[0014] Take a handmade porcelain plate with a height of 1500mm and a width of 800mm. Drill 2 holes of Φ30mm and a distance of 200mm in the upper part of the porcelain plate, and drill three holes of Φ25mm and a distance of 150mm in the lower part of the porcelain plate. After glaze, use 2 round carbon carbide rods to pass through the 2 holes on the upper part of the porcelain plate, hang them in the hanging electric kiln, put 3 silicon carbide open circular rings (Φ150mm, the weight of each open circular ring 500 grams) into the three holes in the lower part of the porcelain plate, close the furnace door, gradually raise the temperature to 1200°C, keep it warm for 10 minutes, stop heating, let the temperature of the kiln drop to room temperature naturally, and burn out a piece of plate of large red porcelain plates.

Embodiment 2

[0016] Take a piece of extruded porcelain plate with a height of 2000mm and a width of 1200mm, drill 2 holes of Φ35mm and a distance of 500mm in the upper part of the porcelain plate, and drill 5 holes of Φ25mm and a distance of 150mm in the lower part of the porcelain plate, and put the cadmium on the porcelain plate. After the red glaze, use 2 round silicon carbide rods to pass through the 2 holes on the top of the porcelain plate, hang them in the hanging electric kiln, put 5 silicon carbide circular rings (Φ150mm, the weight of each open circular ring 500 grams) into the five holes in the lower part of the porcelain plate, close the furnace door, gradually raise the temperature to 1200°C, keep it warm for 10 minutes, stop heating, let the temperature of the kiln drop to room temperature naturally, and burn out a piece of plate of large red porcelain plates.

Abstract

A method for solving a problem of protrusion of a cadmium red glazed porcelain plate by counterweights includes steps: drilling 3-5 holes in the lower portion of the porcelain plate; when the cadmium red glazed porcelain plate is hung in a suspension firing electric kiln, penetrating to hang 3-5 silicon carbide open circular rings into holes in the lower portion of the porcelain plate, closing a door of the kiln, gradually heating to 1200+ / -50 DEG C, keeping the temperature for 10+ / -2min, stopping heating, and naturally cooling the kiln to the room temperature. The porcelain plate fired according to the method is smooth and free of protrusion, and the problem of protrusion of the cadmium red glazed porcelain plate in an existing suspension firing process can be solved effectively.

Description

technical field [0001] The invention relates to a method for solving the convex plate of a cadmium red glaze porcelain plate by adopting a counterweight. Background technique [0002] In the hanging firing process, the cadmium red glazed porcelain plate is often due to the uneven thickness of the handmade porcelain plate, the uneven temperature of the hanging fired electric kiln, and the thermal expansion coefficient of the cadmium red glaze is not suitable for the thermal expansion coefficient of the porcelain plate, which often causes burning. The produced cadmium red glaze porcelain plate has a convex plate phenomenon, especially for large-sized porcelain plates, such as: porcelain plates with a height of 1500mm × width 800mm, a height of 2000mm × 1200mm, etc., the convex plate phenomenon is particularly serious. [0003] At present, there is no effective method to solve the problem of the convex plate of the cadmium red glaze porcelain plate in the hanging firing process...
