一、概述线材是热轧生产中断面最小,长度最长,呈盘卷状交货的钢材。就热轧线材的形状而言,有圆形、螺纹圆形等。就热轧线材的规格而言,国外有人认为凡是呈盘卷状交货的统称之为线材,其规格范围为φ5～38毫米或更大。国内外普遍认为其规格范围为φ5.5～13.5毫米呈盘卷状交货的称之为线材。线材的主要用途可归纳为两大类:一为建筑用材料;二为拔丝用原料。作为建筑材料用的线材,钢种以普碳
First, an overview of wire is the smallest cross-section of hot-rolled production, the longest length, was coiled delivery of steel. In terms of the shape of the hot-rolled wire rod, there are a circular shape, a spiral shape, and the like. Hot-rolled wire rod specifications, foreign people think that all coiled delivery collectively referred to as the wire, the specifications for the range of φ5 ~ 38 mm or more. At home and abroad is generally believed that its specifications range of φ5.5 ~ 13.5 mm was called coil wire delivery. The main purpose of wire can be grouped into two categories: one for the construction materials; two wire for the raw materials. As a building material with wire, steel to Cape carbon
