Embodiment 1

[0035] (1) Put 30% calcium-calcium slag, 20% Dongsheng clay and 50% Zhujita clay into the ball mill after processing each raw material by weight percentage, and the particle size after ball milling is less than 200 mesh.

[0036] (2) The ball-milled mixture is placed in a ceramic green body abrasive tool for dry pressing molding, and the molding pressure is 10 MPa.

[0037] (3) After the molded body is dried, spray water and apply glaze. The heating rate of the low-temperature and medium-temperature sections is the same as the traditional method, and the high-temperature roasting temperature is controlled to be 1100°C.

[0038] (4) After keeping the temperature for 90 minutes at the calcination temperature, enter the cooling zone.

Embodiment 2

[0040] (1) Put 40% calcium-silicon slag, 10% Dongsheng clay and 50% Zhujita clay into the ball mill after processing each raw material by weight percentage, and the particle size after ball milling is less than 200 mesh.

[0041] (2) The ball-milled mixture is placed in a ceramic green body abrasive tool for dry pressing molding, and the molding pressure is 10 MPa.

[0042] (3) After the molded body is dried, spray water and apply glaze. The heating rate of the low-temperature and medium-temperature sections is the same as the traditional method, and the high-temperature roasting temperature is controlled to be 1100°C.

[0043] (4) After keeping the temperature for 90 minutes at the calcination temperature, enter the cooling zone.

Abstract

The invention relates to a method for manufacturing a glazed brick by utilizing silico-calcium slag, belonging to the technical field of ceramic manufacture. The glazed brick comprises the following raw materials in percentage by weight: 5%-40% of the silico-calcium slag, 0%-10% of Dongsheng clays and 50%-95% of bamboo partridge tower clays. Due to the adoption of the invention, the shortage crisis of raw mineral materials is weakened and the discharge of the silico-calcium slag is reduced, and an energy-saving type ceramic product is produced; the production energy consumption of ceramics can be reduced and the utilization efficiency of resources is enhanced by preparing low-temperature glaze materials adapted to calcium silicate because the firing temperature of a blank body is reduced through the calcium silicate contained in the silico-calcium slag; the invention not only reduces the pollution, but also increases a new member for building materials; and in addition, the novel glazed brick prepared by using the method has various properties which all accord with or surpass the national standard.

Description

Technical field: [0001] The invention relates to a method for manufacturing glazed tiles using calcium-silicon slag, and belongs to the technical field of ceramic manufacturing. Background technique [0002] There are a wide range of raw materials for making ceramics, but with the dwindling of natural resources, especially the reduction of high-quality raw materials, the production of ceramics is limited. At home and abroad, attention has been turned to the use of industrial waste to manufacture ceramics. However, at present, waste ceramics generally have unfavorable factors such as complex components and difficult product quality control, which limits its development. As we all know, my country is a big country producing ceramics in the world, and the output of architectural ceramics has ranked first in the world since 1998. With the depletion of high-quality ceramic resources, it is imminent to seek recyclable ceramic raw materials. Calcium silicate slag is the residue a...
