Abstract
The present invention is production process of glass ball for producing alkali resisting glass fiber. The materials including quartzite, calcite, zirconite, rutile, fluorite, potassium nitrate, sodium carbonate and chamotte are crushed and mixed to form the mixed material; and the mixed material is smelted in natural gas burning smelting furnace with zircon corundum brick lining and further processed through cooling, clarification, ball making and annealing to produce alkali resisting glass ball with high zirconia content. The said production process has high product output, low production cost and high product quality and low power consumption, and is easy to control.
Description
Technical field
The invention belongs to the production method of the alkali-resistant glass marble in the building materials industry, particularly a kind ofly make imitation frosted glass with Sweet natural gas and adopt the production of horse shoe flame kiln to contain high zirconia (ZrO
2) the production method of glass sphere.This glass sphere especially is suitable as raw material and is used to produce alkali resistant glass fibre.
Background technology
Alkali resistant glass fibre is to make the glass fiber reinforced cement goods enhancing base material of (being called for short GRC), because this kind goods have light weight, intensity height, do not fire, designability is strong, easy-formation, long service life, cost is better than advantages such as magnesium cement far below glass reinforced plastic, magnesium cement and long-term behaviour.At home, be widely used in outer building and the civil engineering work, not only be used for cold district, and extend to the more existing product scope of making by glass reinforced plastic formula magnesium cement usually as materials for wall.But because zirconic content and contains titanium oxide (TiO about 6% generally up to more than 14% in its Chemical Composition
2), therefore, temperature of fusion is up to more than 1600 ℃ when producing it as the glass sphere of raw material, and it is bigger to found difficulty.At present, the method that is used to produce this kind glass ball is to adopt the production of all-electric melting kiln, though this mode of production scaling loss and fly upward the loss less, but exist industrial scale little, every kiln only can be established 1～2 group of apparatus for making pearl ball (2～4T/ daily output), and the glass metal surface temperature is low in the power consumption height, stove, the temperature field is inhomogeneous, and poor product quality, bubble is more and disadvantage such as production cost height.And tradition is used to found the horse shoe flame kiln of alkali-free or c-glass marble, make the liner and the body of heater of kiln owing to adopt conventional refractory materials, if exist resistance to elevated temperatures poor again in order to found alkali-resistant glass marble, defective such as work-ing life is short, thereby can not use it for the production alkali-resistant glass marble so far.
Summary of the invention
The objective of the invention is to improve design a kind of at the existing disadvantage of background technology is fuel with the Sweet natural gas, the production method that adopts horseshoe flame furnace to found alkali-resistant glass marble; Boost productivity and quality product to reach, purpose such as effectively reduce energy consumption and production costs.
Solution of the present invention is on the basic structure basis of invariable of conventional horse shoe flame kiln, changing its furnace lining flame retardant coating into resistant to elevated temperatures high-quality does not have shrinkage cavity oxidation Corhart Zac-block and makes liner, conventional body of heater high thermal resistance is poor to overcome, the life-span short, the disadvantage that is not suitable for being used to found alkali-resistant glass marble; And adopting quartz sand, calcite, zircon sand, rutile, saltpetre, soda ash, fluorite as former, auxiliary material, mixed is evenly sent into again and is founded in the kiln on request after screening; For further save energy and recycle alkali-proof glass waste residue, fiber etc., can introduce in admixtion that the part grog is former with instead of part, auxiliary material.Glass metal after the fusing is sent into apparatus for making pearl ball and is made alkali-resistant glass marble after homogenizing, cooling, thereby realizes its purpose.Therefore, the inventive method comprises:
A, at first will be except that grog former, auxiliary material separated pulverizing after cross 20～40 mesh sieves, grog is crushed to＜5cm; Each composition and proportioning are by intending producing the glass sphere weight percent meter, be respectively: quartz sand 40.0～65.0%, grog 0～30%, rutile 5.5～8.0%, zircon sand 18.0～32.0%, calcite 5.0～9.0%, fluorite 0.8～2.0%, saltpetre 5.0～7.2%, weighing is stand-by respectively for soda ash 18.0～27.0%;
B, first batching: a. mixes saltpetre, fluorite, rutile according to the above ratio, and is stand-by; B. former, the auxiliary material of all the other that simultaneously will be except that grog also mixes according to the above ratio, and is stand-by;
C, preparation compound: start stirrer, treat that compound " a " that it again will be through just joining after working well and " b " are successively or alternately add in the stirrer, mix, and before discharging 2～3 minutes water sprays, the water ratio in the compound is controlled in 3～5% scopes back discharging;
D, found: with above-mentioned prepared mixture or be 3.65～3.75g/cm directly through feeder or with sending into unit weight through feeder again after load weighted grog mixes in proportion
3High-quality not have shrinkage cavity oxidation Corhart Zac-block be to found in liner, the horse shoe flame kiln with fuelled with natural gas, glass melting temperature is controlled in 1600 °～1640 ℃ scopes;
E, cooling clarification, discharging: the high temp glass liquid of founding, dog-hole in stove flows into and flows into the feeding pond again after work pool cooling clarification, the homogenizing and export through the feeding pond, with the form discharging and the ball-making device system of the sending into ball of material thigh, the temperature of material thigh is controlled in 1150 ± 20 ℃ of scopes;
F, system ball: the material stock-traders' know-how cutting machine of sending into ball-making device is cut into blank, sends into the shaper moulding again, after anneal, promptly makes by heavy its Chemical Composition of per-cent and is: SiO
