Welding Electrodes

Graphite Powder is used in Arc Welding Electrode manufacture as a component in the Flux. Graphites high oxidation resistance enables it to combine with the molten weld metal material. Precise Graphite particle size distribution ensures easy extrusion and elimination of cracks in the flux coating.
Graphite addition to the flux is primarily in hard facing electrodes and also in nickel and ferro-nickel core wire electrodes used for welding of cast iron requiring machining capability.

Catalysts

Graphite Powder is used as additive in the manufacture of Catalysts. The Graphite Powder even in minor quantities provides the necessity lubrication between the active catalyst powders during the manufacturer of the catalyst pellets and extrusions. Graphites chemical inertness ensures that it does not interfere with catalytic functions which would otherwise POISON the catalyst.

PRECISION FORGING LUBRICANTS

Precision forging normally means close-to-final form or close-tolerance forging. It is not a special technology, but a refinement of existing techniques to a point where the forged part can be used with little or no subsequent machining. Improvements cover not only the forging method itself but also preheating, descaling, lubrication and temperature control practices.
The decision to apply precision forging techniques depends on the relative economies of additional operations and tooling vs. elimination of machining. Because of higher tooling and development costs, precision forging is usually limited to extremely high quality applications.
The following lubricants are recommended for precision forging applications.

REFRACTORIES CERAMICS

Refractory materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they need to be resistant to thermal shock, be chemically inert, and/or have specific ranges of thermal conductivity and of the coefficient of thermal expansion. Natural Graphite is the key additive in many specialized refractories like magnesia-carbon bricks

Glass Bottle Mould

There are, currently, two primary methods of making a glass container the blow and blow method and the press and blow method. In both cases a stream of molten glass, at its plastic temperature (1050C-1200C), is cut with a shearing blade to form a cylinder of glass, called a gob. Both processes start with the gob falling, by gravity, and guided, through troughs and chutes, into the blank moulds. In the blow and blow process, the glass is first blown from below, into the blank moulds, to create a parison, or pre-container. Theparison is then flipped over into a final mould, where a final blow blows the glass out, in to the mould, to make the final container shape. In the case of press and blow process, theparison is formed with a metal plunger, which pushes the glass out, into the blank mould. The process then continues as before, with the parison being transferred to the mould, and the glass being blown out into the mould.

Friction Materials

Graphite in view of its lamellar structure is widely used in the production of friction materials. In the direction of motion the lamellar structure provides easy shear resulting in low friction. In highly loaded stationary surfaces, the lamellar structure has sufficient strength to prevent contact between the surfaces under pressures.
