Embodiment 1

[0048] The glass batch is made by weighing and mixing. The composition (weight) of the glass batch is: 60 parts of lead-zinc smelting slag, 26 parts of quartz, 15 parts of lithium feldspar, 4 parts of soda ash, 2 parts of zinc oxide, barium carbonate 4 parts, 2 parts of borax, 2 parts of chromium oxide, 0.2 part of copper oxide, and 0.04 part of carbon powder.

[0049] The composition and content of the lead-zinc smelting slag are SiO 2 40.20%, AL 2 o 3 13.60%, CaO19.84%, MgO3.31%, K 2 O+Na 2 O1.93%; Fe 2 o3 9.66%, ZnO0.71%, PbO0.06%.

[0050] Put the above-mentioned glass batch material in a mullite crucible and melt it in a box-type electric furnace at a temperature of 1480°C for 3 hours. After the melting is completed, pour the glass liquid into water to become glass pellets. 700 grams of glass granules were spread flat in a refractory mold with a size of 120×120 mm and crystallized in a box-type electric furnace at a crystallization temperature of 1020° C. Thereby, ...

Embodiment 2

[0053] The glass batch is made by weighing and mixing. The composition (weight) of the glass batch is: 50 parts of lead-zinc smelting slag, 33 parts of quartz, 15 parts of lithium feldspar, 3 parts of soda ash, 3 parts of zinc oxide, barium carbonate 4 parts, 2 parts of borax, 2.2 parts of chromium oxide, 0.06 part of copper oxide, and 0.1 part of carbon powder. The composition and content of the lead-zinc smelting slag are the same as in Example 1.

[0054] The above-mentioned glass batch materials were melted in a glass tank furnace with a temperature of 1480° C. for 3 hours, and after the melting was completed, the molten glass was directly poured into water to become glass pellets. 26 kg of glass granules were spread flat in a refractory mold with a size of 6000×9000 mm and crystallized in a shuttle kiln fueled by liquefied petroleum gas, with a crystallization temperature of 1060°C. Thus, a green glass-ceramic product of 600×900×18 mm can be obtained.

[0055]

Embodiment 3

[0057] The glass batch is made by weighing and mixing. The composition (weight) of the glass batch is: 40 parts of lead-zinc smelting slag, 38 parts of quartz, 24 parts of lithium feldspar, 7 parts of limestone, 2 parts of soda ash, and 2 parts of zinc oxide. 4 parts of barium carbonate, 2 parts of borax, 2.5 parts of chromium oxide, and 0.2 parts of carbon powder. The composition and content of the lead-zinc smelting slag are the same as in Example 1.

[0058] The above-mentioned glass batch materials were melted in a glass tank kiln at a temperature of 1480° C. for 3 hours, and after the melting was completed, the molten glass was directly flowed into water to become glass pellets. Spread 26 kg of glass pellets in a refractory mold with a size of 6000×9000 mm and crystallize in a shuttle kiln fueled by liquefied petroleum gas at a crystallization temperature of 1050°C. Thus, a green glass-ceramic product of 600×900×18 mm can be obtained.

Abstract

The invention relates to a green glass-ceramic plate made from lead-zinc smelting slag and a manufacturing method thereof. The glass raw material is prepared from the following components in parts by weight: 40 to 60 parts of lead-zinc smelting slag, 26 to 38 parts of quartz, 15 to 24 parts of lithium feldspar, 2 to 4 parts of soda ash, 2 to 3 parts of zinc oxide, 2 to 5 parts of barium carbonate, 1 to 3 parts of borax, 2 to 2.5 parts of chromium oxide, 0 to 0.2 part of copper oxide and 0.04 to 0.2 part of carbon powder. The invention is not only in line with the common glass-ceramic produced by completely adopting industrial materials on the aspect of the performance, but also can realize waste utilization, reduce the environmental pollution, the product cost and the melting temperature of glass, improve the melting speed and the melting furnace efficiency of the glass, decrease the energy consumption and can be widely applied to building decoration materials, especially applied in various building decoration engineering, such as inside and outer walls, floors, pillars, table boards of the building, and the like.

Description

technical field [0001] The invention relates to a glass-ceramic product and a manufacturing method thereof. Background technique [0002] Glass-ceramic is a polycrystalline material obtained by controlling the crystallization of glass. At present, glass-ceramics has formed a special category of materials, with various varieties and different properties, and has a very wide range of uses. Glass-ceramic plate is one of many varieties of glass-ceramics. It is a new type of high-grade building decoration material with high strength, wear resistance, corrosion resistance, weathering resistance, non-absorbent, easy cleaning and maintenance, and no radioactive pollution. Features and uniform color tone, soft and crystal-clear luster, dense and flawless surface and other excellent appearance characteristics. Because the properties of the glass-ceramic plate are superior to natural stone in all aspects, it has been widely used in high-end decoration projects such as interior and ex...
