Problems solved by technology

Since the 1980s and 1990s, in the practice of ceramic production and scientific research, the phenomenon of self-glazing or self-release glaze or self-analysis glaze or self-generated glaze in the firing process of clay tires has been paid attention to. Adding an activator to the solid-phase structure, liquid-phase precipitation capillary force, etc. have been discussed in many aspects, but so far, the one-time firing technology of self-generated glaze ceramics is still in the process of practical application

Embodiment Construction

[0017] The present invention is described below in conjunction with embodiment.

[0018]The one-time firing process of self-generated glaze ceramics includes raw material selection, batching, crushing, sieving, mixing, impurity removal, iron removal, pressure filtration, mud refining, molding, kiln loading, one-time firing, kiln exit, quality inspection, and finished product packaging . Among them, a magnetic iron remover is used for iron removal, and the magnetic field strength is 15,000 to 30,000 gauss. Iron removal can adopt multi-stage iron removal, such as three-stage iron removal, which is beneficial to continuous production. Among them, mud training is divided into first mud training and second mud training, and an ancient process is set between the first mud training and the second mud training. Among them, ball mill is used for pulverization, vibrating sieve machine is used for sieving, agitator is used for mixing, filter press is used for pressure filtration, and m...

Abstract

The invention provides a kiln transmutation autogenous glaze Shandong celadon, a mud material and a method. A ceramic kiln employs a redox alternating atmosphere system to roast the unpainted clay idol into autogenous glaze Shandong celadon. The autogenous glaze Shandong celadon has a green glaze layer, or both blue glaze layer and blue porcelain body. The method can ensure effective precipitation of glaze layer by ceramic unpainted clay idol and enrichment on the surface in one roast, so as to obtain a Shandong celadon finished product through kiln transmutation. The method helps improve productivity and yield of Shandong celadon, saves energy and protects the environment, in particular reduces carbon emissions, and is a great-leap-forward progress for ceramic production.

Description

technical field [0001] The invention relates to celadon manufacturing technology, in particular to a kind of kiln-transformed self-generated glaze Lu celadon and mud material and method. The kiln change means that the firing atmosphere in the ceramic kiln adopts an atmosphere system in which redox changes alternately; the Lu celadon is a type of porcelain that began in the Song Dynasty; It is formed by spontaneous precipitation from the carcass during firing in the kiln and / or the surface effect of carcass firing, that is to say, the two major processes of glaze making and glazing and related steps are completely omitted; the mud refers to The raw material formula for making ceramic mud tires is generally a mixture including a variety of minerals. The implementation of the present invention can ensure that the glaze layer is effectively precipitated and enriched on the surface of the ceramic mud tire in one firing, and the finished product of Lu celadon is fired by kiln trans...
