Embodiment 1

[0045] Embodiment 1: Glass batch is made by weighing and mixing. The composition (weight) of the glass batch is: 60 parts of lead-zinc smelting slag, 21 parts of quartz, 20 parts of limestone, 3.6 parts of soda ash, 3.5 parts of zinc oxide, carbonic acid 3.7 parts of barium, 2 parts of iron oxide, 0.5 parts of manganese dioxide, and 0.2 parts of nickel oxide.

[0046] The composition and mass percentage content of the lead-zinc smelting slag used are: SiO 2 40.20%, AL 2 o 3 13.60%, CaO19.84%, MgO3.31%, K 2 O+Na 2 O1.93%, Fe 2 o 39.66%, ZnO0.71%, PbO0.06%.

[0047] 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 2 hours. After the melting is completed, pour the glass liquid into water to become glass pellets. 500 grams of glass granules were spread flat in a refractory mold with a size of 100×100 mm and crystallized in a box-type electric furnace at a crystallization temperature ...

Embodiment 2

[0048] Example 2: A glass batch is made by weighing and mixing. The composition (weight) of the glass batch is: 50 parts of lead-zinc smelting slag, 25 parts of quartz, 23 parts of limestone, 4 parts of soda ash, 4 parts of zinc oxide, carbonic acid 5 parts of barium, 5.2 parts of iron oxide.

[0049] The composition and mass percentage of the lead-zinc smelting slag used are the same as in Example 1.

[0050] The above-mentioned glass batch materials were melted in a glass tank furnace at a temperature of 1480°C for 2 hours, and after the melting was completed, the molten glass was directly poured 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 black microcrystalline stone product of 600×900×18 mm can be obtained.

Embodiment 3

[0051] Example 3: A glass batch is prepared by weighing and mixing. The composition (weight) of the glass batch is: 40 parts of lead-zinc smelting slag, 35 parts of quartz, 27 parts of limestone, 3.5 parts of soda ash, 2 parts of zinc oxide, carbonic acid 3 parts of barium, 2.2 parts of iron oxide, 0.05 part of cobalt oxide, and 0.2 part of nickel oxide. The color of the product is black.

[0052] The composition and mass percentage of the lead-zinc smelting slag used are the same as in Example 1.

[0053] The above-mentioned glass batch materials were melted in a glass tank furnace with a temperature of 1480° C. for 2 hours, and after the melting was completed, the molten glass was directly flowed 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 black microcrystalline stone p...

Abstract

The invention relates to a black microlite manufactured by using lead and zinc smelting dreg and a manufacturing method thereof. The glass raw material of the black microlite comprises the following components in parts by weight: 40-60 parts of lead and zinc smelting dreg, 21-35 parts of quartz, 20-27 parts of limestone, 3.5-4 parts of soda ash, 2-3.5 parts of zinc oxide, 3-5 parts of barium carbonate, 2-5.2 parts of ferric oxide, 0-0.5 part of manganese dioxide, 0-0.2 part of nickel oxide and 0-0.05 part of cobalt oxide. The invention has the same performance as that of common glass ceramics produced completely by using industrial materials, and can utilize waste, thereby reducing the environment pollution, reducing the production cost and the melting temperature of glass, improving the melting speed and the melting furnace efficiency of glass and reducing the energy consumption. The invention can be widely applied to architectural ornament materials, in particular applied to various building decoration projects such as inner and outer walls, floors, aisle columns, table-boards 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. At present, the raw materials used in the production of micro-ceramics are basically industrial chemical raw materials except quartz sand. The disadvantage of this kind of glass batch material is: high cost of raw materials, high melting temperature of glass, generally between 1500-1550 ℃, such high temperature will inevitably increase the productive consumption of fuel, and intensify the erosion of glass liquid on refractory materials of kiln ; Due to the large amount of chemical raw materials in the glass batch material, the...
