钢钉的生产已有很久的历史,在1700年以前,罗马的建筑物就使用锻炼的铁钉,最初完全是用手工制造的。以后在一些国家将钢板切割后,放在钳床上用锤来锤出钢钉,直到1884年才设计出一种新的有很大改进的制钉机,并开始用冷拉钢丝生产。由于产量的提高,从家庭手工业转变成为一个行业性的生产,到目前为止,为了满足民用和各个工业部门的需要,在产量和品种质量方面发展很快。目前,仅美国每年就生产35万吨钢钉,而且还要进口35万
It has been a long time since the production of steel nails. Before 1700, Roman buildings used nails for training and were initially made entirely by hand. Later in some countries the steel plate after cutting, on the bench with a hammer to hammer out the nail, until 1884 to design a new greatly improved nailing machine, and began to use cold-drawn steel wire production. Due to the increase in production, the shift from cottage industry to an industrial production has so far been very fast in terms of yield and variety quality in order to meet the needs of both civilian and various industrial sectors. Currently, the United States alone produces 350,000 tons of steel nails per year, and imports 350,000
