Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0029] refer to Figure 1-2 , a firing method and a kiln for improving the strength of a ceramic tableware body, comprising the following steps:

[0030] S1, the ceramic tableware is placed in the firing kiln, and in the sealed state of the firing kiln, the ceramic tableware is rotated horizontally in the firing kiln at a speed of 35-40 rpm, and at the same time, the firing kiln is rotated at a speed of 0.5 -0.7°C / min speed heating, after 50-60min, keep the temperature in the firing kiln at 55-77°C;

[0031] S2, stop the fire supply and stop rotating the ceramic tableware, let it stand for 45-55 minutes until the temperature in the firing kiln is maintained at 35-40...

Abstract

The invention discloses a firing method capable of improving the strength of a ceramic tableware green body as well as a firing kiln. The method comprises the following steps: S1, putting ceramic tableware into the firing kiln. A rotating shaft and a turntable which are driven by a first-level motor to rotate are arranged in an upper cavity, so that the ceramic tableware is supported to horizontally rotate in a kiln body; the lower end of a filtering plate is connected with a sealing plate through a pin shaft, a screw rod which is driven by a second-level motor to rotate is arranged in a lowercavity, and the rotating screw rod enables a nut moving up and down to perform traction supporting on the sealing plate through a supporting rod, so that sequential temperature rise and fall of the ceramic tableware in the kiln body is realized under the condition that a furnace body is not extinguished; the ceramic tableware is fired step by step, and a sprayer provides uniform and comprehensiveadhesion spraying for the ceramic tableware doing rotary motion, so that the own adhesiveness is improved; and sequential temperature rise and fall is realized through step-by-step firing, so bubblesand damage to the green body of the ceramic tableware caused by temperature sudden rise and sudden fall in the traditional firing technology can be avoided.

Description

technical field [0001] The invention relates to the technical field of firing ceramic tableware blanks, in particular to a firing method and a kiln for improving the strength of ceramic tableware blanks. Background technique [0002] my country's ceramic preparation technology has a long history. Its various shapes, colorful colors, cool and smooth feel, easy to wash, are deeply loved by the Chinese people, and even the name of my country in the world is based on ceramics. Ceramics, the traditional concept refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. It ranges from the roughest earthenware to the finest fine pottery and porcelain. Ceramic manufacturing technology is common in tableware products in my country and is very successful. [0003] Although China's ceramic technology has a very lo...
