Embodiment Construction

[0024] Accompanying drawing is the technological process schematic diagram of the present invention, as shown in the figure:

[0025] The manufacturing process of the kiln-change glazed porcelain of the present invention comprises the following steps:

[0026] a. Billet: select Fe 2 o 3 Content greater than 1%, TiO 2 For inferior china clay with a content greater than 0.2%, crush and grind the china clay, then ball mill and press filter (fineness requirement: 0.2% to 1.0% after sieve with 10,000 holes); add water to the secondary clay, stir evenly, and mix with The china clay after press filtration is mixed, adding part of iron-titanium oxide and rare earth metal elements accounting for less than 1.0% of the total mass, and pressing it into a green body under a certain pressure;

[0027] b. Bottom glaze making: ① Bottom glaze making: crush and grind the bottom glaze raw materials, add iron and titanium oxide and water ball mill, the fineness requirement of ball milling: 0.1...

Abstract

The invention discloses a process for manufacturing a kiln transformation glaze porcelain. The manufacture process comprises the steps of blank making, forming, enameling and burning, wherein a carving step is arranged between the enameling step and the burning step; in the invention, inferior porcelain clay and secondary clay, which are abundant, low in price and high in ferrotitanium content, are used as main materials for production of kiln transformation glaze porcelains, by adding rare earth metal elements such as iron-titanium oxide, cerium and cesium, etc., the physical-chemical properties of blank glaze, and produced blank colors and kiln transformation colors of porcelain are mixed, and the color development is simple and natural, the coloring is mild, deep colors and light colors go well with each other, and lines and contours are clear; the invention optimizes the allocation of porcelain resources, fully utilizes unrenewable mineral resources, lowers production cost, improves economic benefits of the ceramic industry and opens up a new path for the supply of porcelain materials.

Description

technical field [0001] The invention relates to the field of ceramic processing and manufacturing, in particular to a manufacturing process of kiln-transformed glazed porcelain. Background technique [0002] The ancient color and kiln transformation technology of ancient porcelain making in my country can be regarded as a unique skill in the world. The selection of porcelain clay is an extremely important part of the entire porcelain making process. In the production of traditional ceramics, general ceramic manufacturers are accustomed to using china clay with low iron and titanium content, because Fe in raw glaze raw materials 2 o 3 For every 0.1% increase in the content of Fe, the whiteness of ceramic products will decrease by 1.4 degrees; while Fe 2 o 3 and TiO 2 When the total amount is 0.18-0.57%, every 0.1% Fe increase 2 o 3 or TiO 2 , the whiteness of the product will be reduced by 1.8 degrees. Therefore, in order to improve the whiteness of ceramic products, ...
