Process for making low carbon fibers

摘要

An improved method for forming steel fibers from a process of the type in which the fiber is drawn directly from a pool of molten metals. The improvement revolves around the discovery of an alloy starting material which substantially reduces processing steps and equipment and produces a fiber with improved ductility and strength characteristics. The addition of controlled amounts of copper to a typical low carbon steel alloy provides a wider latitude in the necessary cooling steps to greatly facilitate the control of the ductility and strength of the final product through the use of low cost processing techniques.
