fluxing agents, which form slag on the deposit in the welding process (Refs. 12, 13). Unfortunately, the fluxing agents, such as marble, rutile, and fluorite, occupy more screen space because of their lesser density compared to the metal powders. The addition of ferroalloys, such as ferrochrome, is restricted. The M 7 C 3 carbides are insuffi

Conversion of Mill Scale Waste into Valuable Products via ... Hindawi

In this study, mill scale waste produced in steel companies was recycled to produce valuable products by suitable smelting process using submerged arc furnace and carbonaceous reducing agent. The reductant and fluxing materials were optimized to obtain different valuable products. 2. Experimental.

USA Fluxing agent for removing inorganic deposits from ...

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.

Flux (metallurgy) Wikipedia

In metallurgy, a flux (from Latin fluxus '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 .

Characterization of Fluxing and Hybrid Underfills with Micro ...

As introduced in previous research, the fluxing underfill and resin matrix of the hybrid underfill are composed of four components: a base resin, a curing agent, a fluxing agent to remove the oxide layer formed on the surface of the solder and Cu pads, and an MEC to control the speed of the chemical reaction at room temperature during the process.

Black Dross Processing: Utilization of Black Dross in the ... Springer

In the present study, black dross (BD) residue, a hazardous byproduct generated during secondary aluminum production, has been evaluated as a possible raw material for the production of a calcium aluminatebased ladle fluxing agent to be used in the steel industry. The thermally treated BD [pretreated black dross (PBD)] used as a starting material, consisted of approximately ± wt ...

PDF Iron And Steel Production US EPA

The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 11/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages

Blast furnace | Definition, Temperature, Diagrams, Facts

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as blast furnaces consist of several zones: a crucibleshaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from ...
