前言

一、双金属带锯条在80多年前，最早诞生在美国

1933年,美国杜尔（DOALL）公司发明了带锯床和带锯条，其原理是使用一条环形锯带来切割金属。带锯床在诞生之初使用单金属带锯条进行切割，其材质是碳素工具钢。后经30多年的反复研究，于1964年，杜尔公司成功研发出世界上最早的齿部为高速钢，背部为弹簧钢的双金属带锯条。它以节材、节能、高效于一身的特点，迅速超越了传统的锯切方式，开创了双金属带锯切割的新纪元。

二、我国双金属带锯条的制造，早在30年前诞生在湖南和本溪

1982年国务院正式下发红头文件，批准了国营湖南机床厂在国内率先研制双金属带锯条项目。湖南机床厂于1984年从国外引进全套的双金属带锯条生产设备和生产工艺技术，经过一年多的研发，于1985年秋，成功研制出了我国第一批双金属带锯条。从此，开创了中国生产制造双金属带锯条的先河。

在湖南机床厂之后，国营本溪工具厂于1987年从德国引进全套的双金属带锯条生产设备和生产工艺技术，开始了双金属带锯条的生产制造。

三、上世纪90年代和本世纪初，双金属带锯条在我国得到长足发展

自从湖南机床引进国外设备和工艺技术，研制出我国第一批双金属带锯条之后，由于双金属带锯条自身的优势和国内市场的巨大需求，30年来，我国双金属带锯条工业从无到有，不断发展，取得了很大成绩。国内几十家双金属带锯条生产企业在消化进口技术的基础上，使应用于双金属带锯条冷加工和热处理的设备和工艺技术已经全部国产化。

目前，据不完全统计，国内拥有可以完成双金属带锯条冷加工和热处理完整工艺的厂家达到40多家，其中能够自行焊接加工复合带的厂家超过了一半。另外，为双金属带锯条加工“根带”的下游企业遍布全国四面八方，估计达到几千家，这些厂家完成的主要工序有：下料—对焊—焊口回火—焊口打磨—上护齿带—包装等全部终端工序。

双金属带锯条是一种金属切割下料的新型工具。广泛应用于机械、化工、冶金、造船、航天、食品、电子、国防、建筑等行业。它与传统的弓形往复锯和圆盘锯相比，其切削精度和工作效率成倍提高、极大地降低了材料损耗，具有高精、高效、节能、降耗四大优势。双金属带锯条的问世，被誉为当今“金属下料工艺的一场革命”。双金属带锯条在世界制造业内，已经形成了举足轻重的庞大的独立产业。

在此说明：本书叙述的双金属带锯条应该称为“高速钢双金属带锯条”。国内外市场还有其他双金属带锯条品种：如：硬质合金带锯条、金刚砂带锯条、钨砂带锯条等。据有关资料统计，到2011年，高速钢带锯条在双金属带锯条市场中占有率为93%以上。可见，“高速钢双金属带锯条”的市场规模在双金属带锯条系列中占有绝大部分的比例。本书介绍的“双金属带锯条”专指“高速钢双金属带锯条”。
