The main facility for ferro silicon manufacturing process is electric-arc furnace. The Si content should be adjusted by raw material adding amount. After general ferro silicon manufacturing process, refining procedure is also necessary in order to remove Aluminum, Calcium, Carbon and other harmful elements.
plating metal. The process uses a reducing agent, and the work part surface acts as a catalyst for the reaction. Normally, Ni and Ni alloys are used for this plating. It is costlier as compared to other similar methods. Nickel plating by this method is used to get high resistance to
aluminum alloys are aged, and during this process, a fine dispersion of ele-ments and compounds are precipi-tated that significantly increase mate-rial strength. The diffusion process and precipitation kinetics vary with the alloy chemistry. The cooling process of age-harden-able aluminum alloys not only affects properties such as strength and duc-

Aluminum extrusion is a process by which aluminum alloy material is forced through a die with a specific cross-sectional profile. A powerful ram pushes the aluminum through the die and it emerges from the die opening. When it does, it comes out in the same shape as the die and is pulled out along a runout table.
The process is limited to fluidity metals. This refers to those metal alloys that can flow. It will be nearly impossible to force a metal that can’t flow through the die. Therefore, it is important to evaluate all factors that can affect the fluidity of the metals.

the ram forces the alloy through the opening in the die. In the indirect process, the die is contained within the hollow ram, which moves into the stationary billet from one end, forcing the metal to flow into the ram, acquiring the shape of the die as it does so. The extrusion process has been likened to squeezing toothpaste out of a tube. When

Because brazed joints have a very clean, well-finished appearance, brazing often is the preferred bonding process for manufacturing plumb-ing fixtures, tools, heavy construction equipment and high-quality consumer products. The process is well-suited for joining dissimilar met-als, which gives the assembly designer more material options.
The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be used on high quality bauxite with fairly low content of admixtures, especially silicon.
Centrifugal Casting. Centrifugal casting, sometimes called rotocasting, is a metal casting process that uses centrifugal force to form cylindrical parts. This differs from most metal casting processes, which use gravity or pressure to fill the mold. In centrifugal casting, a permanent mold made from steel, cast iron, or graphite is typically used.
