摘要: 冷镦钢盘条一般为低、中碳优质碳素结构钢和优质合金结构钢,用来冷镦成型制造各种机械标 准件和紧固件。因冷镦工艺要求该钢具有高的洁净度,控制钢中 Si、Al的含量,采用控制轧制和控制冷却工 艺,避免出现马氏体、贝氏体和魏氏体组织,使钢材具有细晶和碳化物球化组织,以提高钢材的塑性和冷顶锻 性能。介绍了国内外冷镦钢的开发和生产情况,化学成分对冷镦性能的影响,冷镦钢的生产工艺特长。

Abstract: The cold heading steel coil generally is low and medium carbon quality steel and alloy structure steel to manufacture various standard mechanical element and fastener by cold heading forming. As the element and faster are formed by cold heading process, the cold heading steel has high cleanliness, to control Si and Al content in steel, and has fine grain and spheroidal cementite structure produced by controlled rolling and cooling process to avoid occurring martensite, bainite and Widmannstatten structure and increase plasticity and cold heading properties of steel. The evolution and production of cold heading steel, the effect of chermical compositions on cold heading properties and the characteristics of production process of cold heading steel are presented in this paper.
