(PDF) PRODUCT DEFECTS IN ALUMINUM EXTRUSION

7.12 Low Hardness As-extruded aluminum is quite soft and is therefore heat-treated by age hardening in furnaces for prescribed temperature-time cycles depending on the aluminum alloy. Due to any number of malfunctions or problems in the furnaces, the aging process may produce insufficient hardness.

Iron

Materials containing finely ground iron(III) oxides or oxide-hydroxides, such as ochre, have been used as yellow, red, and brown pigments since pre-historical times. They contribute as well to the color of various rocks and clays, including entire geological formations like the Painted Hills in Oregon and the Buntsandstein (colored sandstone, British Bunter ).

Electric Arcs

The briquettes are then fed into a smelting shaft furnace, which normally operates on 100 percent sinter feed but can also process 100 percent Waelz oxide or other secondary material briquettes. Typical Waelz oxides consist of zinc (56 to 60 %), lead (7 to 10 %) and cadmium (0.1 to 0.2 %).

K1‐MET

The influence of the Al 2 O 3 content in the remelting slag on chemical reactions and the formation of nonmetallic inclusions (NMIs) during electroslag remelting of a bearing steel is focused. In addition, numerical simulations on the NMI‐formation are presented, allowing for a better understanding how the type of NMI can be adjusted.

Charcoal

Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen.

Extrusion

Commonly extruded materials include metals, polymers, ceramics, concrete, modelling clay, and foodstuffs. The products of extrusion are generally called extrudates. Also referred to as hole flanging, hollow cavities within extruded material cannot be produced using a simple flat extrusion die, because there would be no way to support the centre barrier of the die.
