  • FluxBasics What isFlux

    Now the flux is a wetting agent for the solder alloy. The better a flux is at this, the better it performs in something like a solderability test. The activator package “jump starts” the solder flow by etching the surface and the surfactant promotes the continuation of the solder flow by wetting the surface.

  • Iron andSteel SlagStatistics and Information

    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. From this and the added fluxing agents molten slag and iron are formed.

  • Novel design of ferronickel smelting slag by utilizing red

  • Lime, an essential component in thesteelindustry

    Calcite or lime is used in the steel industry because of its flux action which allows it to lower the concentration of impurities in the steel (above all silica and alumina, but also sulphur, phosphorus…) and so produce slag. To achieve this oxygen is blown through the molten iron, bringing about a fall in the percentage of carbon.
