冷拉型钢的发展历史回顾
最早的钢材成型手段远没有现在这么先进，都是靠手工锻造得到的，直到第一次工业革命有了机器的出现，手工锻造才被机器锻造所取代。随着蒸汽机的发明和蒸汽作为动力的应用，有了工业汽锤的出现，后来电气技术的发展和电动机驱动的应用，促进了机械压力机的发展，再后来出现了液压元件和液压技术，这些技术手段在型钢锻造领域都有很好的应用。
The earliest steel forming methods are far from being as advanced as they are now. They were obtained by manual forging. Until the first industrial revolution saw the emergence of machines, manual forging was replaced by machine forging. With the invention of the steam engine and the application of steam as power, with the emergence of industrial steam hammers, the development of electrical technology and the application of electric motor drives have promoted the development of mechanical presses, and then hydraulic components and hydraulic technology have appeared. Technical means are well applied in the field of section steel forging.
在最近半个多世纪，我国的模锻设备和锻造技术得到了飞速的发展，主要是得益于计算机技术、加工制造技术等科学的发展。这不仅使得设备的性能得到了进一步的提高，还为整个冷拉型钢行业发挥了巨大的作用。虽然与工业发达国家相比，我国在这个领域的设备的技术和水平还有一定的差距，还有待进一步改善。
In the past half century, China's die forging equipment and forging technology have developed rapidly, mainly due to scientific developments such as computer technology and manufacturing technology. This not only makes the performance of the equipment further improved, but also plays a huge role for the entire cold drawn steel industry. Although compared with industrially developed countries, there is still a certain gap in the technology and level of equipment in this field in China, which needs to be further improved.
