Description of the Function of Aluminum Alloy Flux

图片
  Ⅰ . Fluxes for aluminum alloys are used in production Fluxes for aluminum alloys are widely used in the production of primary aluminum and secondary aluminum to improve the quality of the melt and the recovery rate of metallic aluminum.   Ⅱ . The role of fluxes for aluminum alloys 1. Fluxes for aluminum alloys   can change the wettability of aluminum melt to oxide (aluminum oxide), making aluminum melt easy to separate from oxide (aluminum oxide), so that most of the oxide (aluminum oxide) enters the fluxes for aluminum alloys and reduces the oxide content in the melt.   2. Fluxes for aluminum alloys can change the state of the oxide film on the surface of the melt. This is because it can break the solid and dense oxide film on the surface of the melt into fine particles, which is beneficial for the hydrogen in the melt to permeate and escape from the particle gaps of the oxide film and enter the atmosphere.   3. The existence of the fluxes for aluminum alloys...

Application of Fluxes for Aluminum Alloys

图片
  What is the role of aluminum alloy flux? Now SATA will introduce it in detail for you.   1. The principle of fluxes for aluminum alloys The effect of high-efficiency fluxes for aluminum alloys   is very good. It is mainly to remove the hydrogen and floating oxidized slag in the molten aluminum to make the molten aluminum more pure, and it also has the function of removing slag.   The principle is that some components of aluminum alloy flux are easy to decompose at high temperature, the generated gas reacts with hydrogen, and can also strongly adsorb slag, which can play a certain role in slag removal.   2. The application of fluxes for aluminum alloys Fluxes for aluminum alloys can be used for a variety of aluminum alloys, and alloys with relatively high magnesium content and aluminum-magnesium alloys cannot be used if unexpectedly. It can be used for pure aluminum smelting for refining and slag removal.   When using it, you only need to sprinkle the alum...

Classification and Requirements of Fluxes for Aluminum Alloys

图片
  Ⅰ . Classification of fluxes for aluminum alloys There are many types of fluxes for aluminum alloys used in aluminum alloy smelting, which can be divided into two categories: covering agent (flux to prevent melt oxidation and burning and gettering) and refining agent (flux for degassing and removing inclusions). The covering agent and refining agent used in different aluminum alloys are different.   However, any fluxes for aluminum alloys   used in the aluminum alloy melting process must meet the following conditions.   Ⅱ . The requirements of fluxes for aluminum alloys 1. The melting point should be lower than the melting temperature of aluminum alloy.   2. The specific gravity should be less than that of aluminum alloy.   3. Fluxes for aluminum alloys can absorb and dissolve the inclusions in the melt, and can discharge the gas from the melt.   4. It should not react chemically with metal and furnace lining. If it reacts with metal, it should only ...

Advantages and Uses of Aluminium Granulated Fused Refining Fluxes

图片
  Ⅰ . Product introduction of granular refining flux:   Granular refining flux is currently the main product in the market. Compared with the traditional powdered refining flux, it has better effect, less loss and is more environmentally friendly.   Ⅱ . Product advantages of granular refining flux   1. Traditional powder refining flux: the loss rate of aluminum is 2-3%, the melting point is not fixed and the melting point is higher than 740 degrees, the form in the aluminum liquid is solid powder, and a lot of harmful gases are generated during processing, and the slag and gas removal is not obvious .   2. Advantages of the granular refining flux : the aluminum loss rate is 0.3-0.5%, the melting point is fixed and less than 600 degrees, the form in the aluminum liquid is liquid, the composition is stable and uniform, no harmful gas is generated, and the slag and gas removal effect is obvious.   Ⅲ . Product use of granular refining flux:   1. The granul...

The Introduction & Usage Method of Mg Remover Flux

图片
  Ⅰ . The role of Mg remover flux   The design of the flux composition is based on substances such as chloride and fluoride (sodium fluorosilicate, sodium chloride, aluminum fluoride...), under the combined action of dispersed small bubbles and active flux, as the reaction speed is adjusted to achieve the purpose of strong magnesium removal, while effectively removing calcium and other metal inclusions in the aluminum melt, and has the functions of refining and degassing, removing inclusions, etc., so as to achieve the purpose of purifying the aluminum melt.   Ⅱ . How to use magnesium removal agent   1. Mg remover flux is sprayed with inert gas as the carrier. The powder spraying tank is slowly circling in the furnace and the inert gas pressure should not be too high. The Mg remover flux   should be effective in the furnace and fully react with the aluminum melt.   2. Before spraying, the burner should be turned off. During the spraying process, make sure t...

The Characteristics of Different Types of Sodium Hexafluoroaluminate

图片
  Sodium hexafluoroaluminate is also called cryolite, which sounds very good. It is a tasteless mineral of white, fine crystals, which has a greater solubility than natural cryolite. Easy to absorb water and become damp, it is mainly used as a cosolvent in aluminum electrolysis industry, a wear-resistant filler for rubber and grinding wheels, and an opalizer for glass and enamel, etc.   Sodium hexafluoroaluminate   can be divided into high molecular weight sodium hexafluoroaluminate and low molecular weight sodium hexafluoroaluminate according to its molecular ratio of sodium to aluminum. According to its physical properties, it can be divided into sandy cryolite, granular cryolite and powdered cryolite. The shapes, functions and requirements are also different. Next, SATA will explain it to everyone.   Ⅰ . The characteristics of sandy sodium hexafluoroaluminate   1. Its low melting point and fast melting speed can shorten the time to enter normal working state....
