Embodiment

[0023] The daily-use glass-ceramic production method with smooth surface is characterized in that it comprises the following production steps:

[0024] (1) Production of semi-finished products

[0025] Using conventional production methods, the raw material of glass ceramics is smelted at 1400°C to form glass slurry, and the glass slurry is metered and put into a steel mold installed on a press, and pressurized to form a semi-finished product of daily-use glass ceramics;

[0026] (2) Flame polishing treatment of products

[0027] The semi-finished products are processed in the flame polishing room; the flame polishing room is equipped with a rotating disk, a graphite male mold and 2 combustion nozzles, and a supporting mold is set on the rotating disk, of which the flame nozzle of the No. The flame hole of the combustion nozzle is set in the middle, and the appearance of the graphite male mold is the same as the appearance of the inner cavity of the product;

Abstract

The invention discloses a production method of daily-use glass ceramics with a smooth surface, which is characterized in that it comprises the following production steps: (1) semi-finished product production; (2) product flame polishing treatment; (3) product shaping; (4) annealing deal with. The method of the present invention makes the surface of the daily-use glass-ceramic product smooth, basically eliminates the tiny cracks on the surface of the product, eliminates the burrs and rough surfaces at the edge, and becomes smooth and smooth, and the appearance of the product reaches regularity and no deformation. The quality meets the standard requirements of GB / T30771 "Glass Ceramics for Daily Use".

Description

technical field [0001] The invention relates to the field of glass ceramics, in particular to a method for producing daily-use glass ceramics with a smooth surface. Background technique [0002] In the GB / T30771 "Glass Ceramics for Daily Use" standard, glass ceramics are defined as "a type of ceramic composite material composed of a crystal phase and a glass phase. Generally, the glass is properly heated to produce a sufficient amount of crystal phase in the glass. Obtained." The definition of glass ceramics for daily use is "glass ceramic products for daily use". [0003] The appearance, shape and use of daily-use glass ceramics are similar to those of daily-use ceramics, but the materials are different from those of daily-use ceramics, and the production process is also different. The production process of daily-use glass ceramics is similar to that of daily-use glass, but there are differences. It is through high-temperature melting of composite materials, hot-press form...
