Production of Stainless Steel Fiber by Sheet Shaving of Hot Water Soluble Resin Coated Coil

Abstract

A new method of producing stainless steel fibers by shaving coiled sheet has been developed. To prevent the fibers from sticking to each other, hot water soluble resin coated coil is used. This coating decreases fiber sticking from 40% to 8%, thus enabling uniform and fine fibers to be produced. It was also found that thinner fibers can be obtained when thin sheets are used than when the feed rate is decreased. As a result, fibers with equivalent diameters of 14 μm were obtained with metal sheet of 10 μm thickness and feed rate of 5 μm/rev. The tool life until re-grinding was about 40 minutes and productivity was about 15 kg/h, confirming that industrial production is possible.
