Problems solved by technology

The disadvantages of this kind of glass batch material are: high cost of raw materials, high melting temperature of glass, generally between 1500-1550°C, such high temperature will inevitably increase fuel consumption and intensify the erosion of glass liquid on refractory materials of kiln; in addition, due to There are many chemical raw materials in the glass batch, which also increases the erosion of the glass liquid on the refractory material of the furnace, which affects the service life of the equipment

Embodiment 1

[0019] The glass batch is made by weighing and mixing. The components of the glass batch are calculated in parts by weight: 60 parts of molybdenum tailings, 25 parts of quartz sand, 28 parts of limestone, 3.5 parts of soda ash, 3.2 parts of zinc oxide, 3.2 parts of barium carbonate , 4 parts of iron oxide, 0.5 parts of manganese dioxide, 0.2 parts of nickel oxide.

[0020] Put the above-mentioned glass batch 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, the molten glass is poured into water to become glass particles. Spread 500 grams of glass pellets in a refractory mold with a size of 100×100 mm, and perform crystallization in a box-type electric furnace with a crystallization temperature of 1020°C. After grinding and cutting the crude black glass-ceramic, a sample of 100×100×18 mm black glass-ceramic can be obtained.

Embodiment 2

[0022] The glass batch is made by weighing and mixing. The composition of the glass batch is calculated in parts by weight: 50 parts of molybdenum tailings, 20 parts of quartz sand, 33 parts of limestone, 5 parts of soda ash, 4 parts of zinc oxide, and 6 parts of barium carbonate. , 6 parts of iron oxide.

[0023] The above-mentioned glass batch materials are melted in a glass tank furnace at a temperature of 1480°C for 3 hours, and the molten glass is directly poured into the water to become glass particles after the melting is completed. Spread 26 kilograms of glass particles in a refractory mold with a size of 6000×9000 mm, and crystallize in a shuttle kiln using liquefied petroleum gas as fuel, and the crystallization temperature is 1050°C. After grinding and cutting the crude black glass-ceramic product, a 600×900×18 mm black glass-ceramic product can be obtained.

Embodiment 3

[0025] The glass batch is made by weighing and mixing. The composition of the glass batch is calculated in parts by weight: 70 parts of molybdenum tailings, 15 parts of quartz sand, 27 parts of limestone, 3.5 parts of soda ash, 2 parts of zinc oxide, 3 parts of barium carbonate , 3 parts of iron oxide, 0.05 parts of cobalt oxide, 0.2 parts of nickel oxide.

[0026] The above-mentioned glass batch material is melted in a glass tank furnace at a temperature of 1480°C for 3 hours. After the melting is completed, the glass liquid is directly poured into the water to become glass particles. Spread 26 kilograms of glass particles in a refractory mold with a size of 6000×9000 mm, and crystallize in a shuttle kiln using liquefied petroleum gas as fuel. The crystallization temperature is 1060°C. After grinding and cutting the crude black glass-ceramic product, a 600×900×18 mm black glass-ceramic product can be obtained.

Abstract

The invention discloses a method for manufacturing black microcrystalline glass plates from molybdenum tailings, which comprises the following steps: mixing a certain part by weight of molybdenum tailings, quartz sand, lime stone, sodium carbonate, zinc oxide, barium carbonate, ferric oxide, manganese dioxide, nickel oxide and cobalt oxide to prepare a glass batch; melting the glass batch into molten glass, and then, pouring the molten glass into water to form glass particles; horizontally laying the glass particles in a fire-resistant mold for crystallization heat treatment; and grinding and cutting black microcrystalline glass crude products after crystallization heat treatment to form finished products. By using the molybdenum tailings for manufacturing black microcrystalline glass plates, the invention not only reduces the stockpiling amount of tailings and relieves the environmental pollution, but also can improve the product performance and reduce the production cost, thereby having good social benefit and economic benefit.

Description

Technical field [0001] The invention relates to a method for manufacturing a glass-ceramic plate, in particular to a method for manufacturing a black glass-ceramic plate from molybdenum tailings. 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 a wide variety of different properties, and a very wide range of uses. Glass-ceramic plate is one of the many varieties of glass-ceramic. It is a new type of high-end architectural decoration material with high strength, wear resistance, corrosion resistance, weathering resistance, no water absorption, easy cleaning and maintenance, and no radioactive pollution. The physicochemical properties and uniform color tone, soft and crystal luster, compact and flawless surface and other excellent appearance characteristics. Since the performance of the glass-ceramic plate is superior to natura...
