Problems solved by technology

However, because the flame of the horseshoe flame kiln burns in the shape of a horseshoe in the kiln, that is, it burns on one side, the flame reaches two-thirds of the length of the kiln cavity and turns, and the exhaust gas is discharged from the other side, and the direction is changed every 30 minutes. Therefore, the temperature in the kiln fluctuates greatly, and there is an obvious temperature difference in the width direction of the kiln pool, the kiln pressure is large, the batch material is flying, and the energy consumption is still high (natural gas consumption reaches 640m 3 / ton of glass balls) and the aspect ratio of the kiln body is small, generally only 1.5 to 1.7, resulting in a short melting time for the molten glass in the kiln, and the quality of the produced glass balls is still not ideal. In addition, there are still materials in this production method. The strand temperature is low, which is easy to cause crystallization and devitrification, and affects the ball forming rate of the glass ball, which seriously affects the product quality; the glass ball produced by this method is used for drawing, and the drawing rate is only about 83.0%

Embodiment 1

[0019] This embodiment takes the preparation of the required mixture for every 100kg of alkali-resistant glass balls produced as an example: the amount of each raw material and auxiliary material is respectively: 57.0kg of quartz sand, wherein: SiO 2 ≥99.0%, Fe 2 o 3 2 o 3 2 65%, TiO 2 2 o 3 2 87%, ZrO 2 >1.5%, Al 2 o 3 2 2 o 3 2 1.8kg of 94% fluorite, 23.5kg of soda ash with a purity of 99.6%, and 6.5kg of potassium nitrate with a purity of 94.0%. Each component is the powder that passes through a 40-mesh sieve after crushing.

[0020] Mix potassium nitrate, fluorite, rutile and other raw materials and auxiliary materials respectively into two kinds of initial mixing materials, and then alternately send them into the mixer and mix them evenly; finally add 3kg of clear water, continue stirring for 3 minutes, and then discharge;

[0021] The mixed materials that have been prepared successively are fed into the melting pool 13 of the Shuanglong kiln through the feeder t...

Embodiment 2

[0024] When the chemical composition of each raw material and auxiliary material in embodiment 1 is constant, produce every 100kg glass ball, take by weighing 53.7kg quartz sand, 32.5kg zircon sand, 7.1kg rutile, 7.45kg calcite, 1.9kg fluorite, 28kg soda ash And 6.5kg potassium nitrate, be mixed with mixed powder, under the processing condition of embodiment 1, can produce containing ZrO 2 17.0% alkali-resistant glass balls.

Embodiment 3

[0026] When according to the raw material composition in embodiment 1, take by weighing respectively by producing 100kg glass ball: quartz sand 45.3kg, zircon sand 22.4kg, rutile 5.3kg, calcite 4.7kg, fluorite 1.5kg, soda ash 19.5kg, potassium nitrate 4.6kg kg, after making mixed powder, add 30kg of clinker with similar composition to the glass ball to be produced, and melt it at a temperature of 1610°±10°C to obtain ZrO-containing 2 Alkali-resistant glass balls around 14.2%.

Abstract

In the invention, quartz, sand, zircon sand, titanis schorl, calcite, fluorite, potassium nitrate, soda ash and some other chamotte are used as raw and auxiliary to high-zirconia alkali-resisting glass ball by melting, cooling, clearing, ball-making and annealing, the double-arch furnace melting glass liquid includes heat exchange cell, inside and outside big arches, small furnace, gas ejector, flue pipe, anocelia, front and back facewall, dog-hole, clearing tank and feed entrance. Melting tank made by non-contraction cavities electric smelted corundum brick and qualified silicon brick and double-arch lining or building body are used by said furnace.

Description

technical field [0001] The invention belongs to a production method and a kiln for production of alkali-resistant glass balls in the building material industry. In particular, a kind of natural gas is used as fuel, and a double kiln is used as a furnace to produce high zirconia (ZrO 2 ) production method of alkali-resistant glass spheres. Its glass spheres are especially suitable as a raw material for the production of alkali-resistant glass fibers. Background technique [0002] Alkali-resistant glass fiber is the reinforcing base material for manufacturing glass fiber reinforced cement products (GRC for short). Because this product has light weight, high strength, non-combustibility, strong designability, easy molding, and long service life, the cost is much lower than that of FRP. , Magnesium cement and its long-term performance is better than that of magnesium cement. It has been widely used in construction and civil engineering at home and abroad, not only as a wall m...
