What is aluminum refining agent used for? What's the ingredient?

The final deoxidized molten steel is mainly composed of aluminum.

1, and the refining agent is white powder or granular flux. It is made by drying a variety of inorganic salts and mixing them according to a certain proportion.

2. Function: Refining agent is mainly used to remove hydrogen and floating oxide slag in aluminum liquid, which makes aluminum liquid more pure and has slag removal function.

3. Features: Some components in the refining agent are easy to decompose at high temperature, and the generated gas is easy to react with hydrogen, which has strong adsorption with slag inclusions and quickly escapes from the melt. Other parts also have slag removal function.

4. Scope of application: suitable for ordinary brands of aluminum alloys (alloys with high magnesium content and aluminum-magnesium alloys cannot be used), degassing, refining and slag removal when pure aluminum is melted.

5. Usage: Sprinkle the refining agent on the liquid surface, quickly press it into the aluminum liquid, fully stir it, then let it stand and scrape it flat; For example, it is best to spray the refining agent into the aluminum liquid with inert gas by a jet machine.

Silver white light metal. It has plasticity. Commodities are often made into bars, sheets, foils, powders, tapes and wires. An oxide film can be formed in humid air to prevent metal corrosion. Aluminum powder can burn violently when heated in air, and give off a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. The relative density is 2.70. The melting point is 660℃. The boiling point is 2327℃. The content of aluminum in the earth's crust is the third only to oxygen and silicon, and it is the most abundant metal element in the earth's crust. The development of three important industries, aviation, construction and automobile, requires that aluminum and its alloys have unique properties, which is of great benefit to the production and application of this new metal aluminum. It is widely used.

2065438+07101The list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted out for reference, and aluminum was produced in the list of Class I carcinogens.
