采用光电跟踪切割机切割钢板,在造船、锅炉制造等工业企业中应用已较普遍,但在冶金建筑企业中使用这种工艺的还不多。我们希望冶金建筑企业本着自力更生,艰苦创业的革命精神,结合本单位的具体情况,积极采用这项新技术,以减轻钢材下料时的繁重劳动。——编者 The use of optical tracking cutting machine cutting steel, shipbuilding, boiler manufacturing and other industrial enterprises have been more common, but the metallurgical construction enterprises in the use of this process is not much. We hope that the metallurgical construction enterprises will actively adopt this new technology in light of the revolutionary spirit of self-reliance and arduous pioneering and in light of the specific conditions of their own units so as to alleviate the heavy labor in the unloading of steel products. --editor
