Description

Preparation method for producing aluminum-silicon alloy ingot by using waste glass
Technical Field

Background
The glass is a substance commonly used in modern life of human beings, and can be made into various appliances, utensils, plate glass and the like. The component of ordinary glass is mainly silicon dioxide (SiO)2I.e. the main composition of quartz sandMinute). Sodium carbonate (Na) is generally added in the manufacture of glass2CO3I.e. soda) with potassium carbonate (K)2CO3Potash) to lower the process temperature. Because the consumption of the glass is large, the waste is more, and the waste glass and products can be collected for the sustainable utilization of resources, so that the harm is turned into the benefit, and the waste is changed into the valuable. There are several types of recycling of glass products: as a flux for casting, transformation and utilization, re-melting, raw material recovery and reuse, and the like. Although these applications have been successful, the added value of the recycled product is low.
Similarly, scrap aluminum is a commonly used scrap material, and a large number of scrap automobiles and beverage cans, etc. contain a large amount of aluminum. In the recycling process, aluminum is oxidized to generate certain products such as aluminum ash, and the products are not worth further extracting aluminum due to low grade and are discarded.
At present, aluminum-silicon alloy is mainly manufactured by diffusing liquid aluminum and solid silicon. Because the melting point of the aluminum is about 660 ℃, the aluminum is melted into liquid, then the silicon is melted to form aluminum-silicon alloy liquid, and then the aluminum-silicon alloy liquid is inspected and cast into aluminum-silicon alloy cast ingots. Since silicon has a melting point of 1440 ℃, its diffusion rate is slow, so the manufacturing process takes a long time and consumes a lot of energy. In addition, during the process of manufacturing the alloy, the silicon surface is easy to form oxide (SiO)2) The diffusion of silicon can be further reduced, and meanwhile, the loss rate of silicon is up to 10-20%, and the production efficiency and the cost are seriously influenced.
