Dec 08, 2013· Bath stirring improves the mixing of metal and slag and helps in the rate of dephosphorization. Good stirring with the addition of the fluxing agents such as flour spar etc., also improves phosphorus removal by increasing the dissolution of lime, resulting in a highly basic and fluid liquid slag. Sulphur reaction
Apr 19, 1977· A fluxing process for removing inorganic deposits from equipment used to produce base metals from ores by inclusion of alkali metal silicates, preferably as liquids or hydrates, as at least 10% of the fluxing agent, thereby improving effectiveness of the fluxing process.

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
Steel Furnace Slag is produced in a (BOF) Basic Oxygen Furnace or an (EAF) Electric Arc Furnace. Hot iron (BOF) and/or scrap metal (EAF) are the primary metals to make steel in each process. Lime is injected to act as a fluxing agent.
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which usually contains acid, is used to remove the surface is commonly used to descale or clean steel in various steelmaking processes.
In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were carbonate of soda, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.
Galvanizing – The Use of Chemical Fluxes Rev Aug03 Introduction As discussed in GalvInfoNote #2, "The Continuous HotDip Galvanizing Process for Steel Sheet Products", it is absolutely necessary to have the steel sheet free from any surface oxides as it enters the molten zinc coating bath.
agent. The metallic iron produced by such a furnace contains a relatively high proportion of carbon (4%) and is passed to the steelmaking process as a liquid at approximately 1450C, called "hot metal". Refining: Steelmaking The refining of iron to make steel is where the carbon content of .

and finally magnetic separation to remove fluxing salts and other waste products from the aluminum. First, raw material is fed into a long rotating drum or a wetball mill where water soluble contaminants are rinsed into waste water and removed (leached). The remaining washed material is then screened to remove fines and undissolved salts.

Just as the flux itself spreads onto the surface, the solder alloy must also. A good flux will lower the surface tension between the metal and the molten solder. Before, the surfactant was a wetting agent to help the flux spread. Now the flux is a wetting agent for the solder alloy. The better a flux is at this, the better it performs in ...

Although this would not be an issue if the steel slag used contains a low amount of FeO, the EAF slag used in this research work contains approximately 37 wt% of FeO. FeO is a powerful fluxing agent and at high concentration, an excessive amount of the glassy phase was formed.
An improved fluxing method for the galvanization of steel, particularly batch galvanization, is disclosed. In this process, a metallic element is deposited (for example, by electroless plating) on the surface of the steel sheet or other article prior to its being dipped in the galvanization bath. Preferred metals for use in this fluxing process are tin, copper, nickel, with tin being more ...
