广泛应用工艺性能符合现代技术发展水平要求的钢和生铁,是加速科技进步的重要途径,而钢和生铁的合金化又是使之达到要求的主要方法之一。钒是重要的合金化元素,它可以细化钢的组织,提高强度、韧性、塑性和耐磨性,改善可焊性和其他物理-力学、工艺、使用等性能,而且还可使某些钢种减少钨、钼、铌的用量。因此,钒作为合金化元素广泛用于结构钢、热强钢和工具钢的生产,特别是油气管、建筑用金属结构、钢轨
The extensive application of steel and pig iron with technological properties that meet the requirements of the development of modern technology is an important way to accelerate the progress of science and technology. The alloying of steel and pig iron is one of the main methods to meet the requirements. Vanadium is an important alloying element, it can refine the organization of steel, improve strength, toughness, ductility and wear resistance, improve weldability and other physical - mechanical, process, use and other properties, but also make some of the steel Reduce the amount of tungsten, molybdenum, niobium. Therefore, vanadium as an alloying element is widely used in the production of structural steels, hot-forgings and tool steels, especially for oil and gas pipelines, construction metal structures, rails
