METHOD FOR MANUFACTURING HOT ROLLED WIRE ROD BY USING LAYING HEAD

摘要

PURPOSE: A method for manufacturing a hot rolled wire rod by using laying head is provided to prevent a scratch defect of the surface of a wire rod by forming lubricant composite material on the sharp bending part of a spiral laying head through which the wire rod passes in high speed. CONSTITUTION: A method for manufacturing a hot rolled wire rod by using laying head includes the step of forming a solid type lubricant and lubricant composite material consisting of metallic matrix(10) fixing the lubricant in the inside of a spiral laying head at a portion where friction is generated intensively due to the surface contact when a wire rod passes the spiral laying head. The lubricant is made of at least one of metallic oxide powder, graphite powder and MoS2 powder. The metallic matrix is metallic powder made of Ni, Fe or Co, or an alloy of Ni, Fe and Co in which alloy elements are added.
