METHOD AND DEVICE FOR SIMULTANEOUSLY RECOVERING NONMAGNETIC STAINLESS STEEL FIBER AND GRINDING OIL FROM STAINLESS STEEL SCRAPS BY USING DRY HEATING METHOD

摘要

PURPOSE: A method and device for recovering nonmagnetic stainless steel fiber and grinding oil from stainless steel scraps simultaneously is provided to prevent environmental pollution by using a dry heating method. CONSTITUTION: A device for recovering nonmagnetic stainless steel fiber and grinding oil from stainless steel scraps is composed of a reaction tube(230) to which the stainless steel scraps are supplied, a heating furnace(240) heating the reaction tube, an automatic feeding unit feeding the scraps to the reaction tube continuously, a cooling unit condensing evaporated materials, a recovery case(270) recovering the condensed materials, and an automatic classifier(280) classifying the stainless steel fiber.
