钒属高熔点稀有金属,具有银灰色光泽。最早于1801年在墨西哥的铅矿中发现,1905年首次应用于工业上。由于钒能改善钢的性能,所以近年来它已成为某些钢的必不可少的组分。随着工业技术的发展,钒的需求量将日益增加。 1.钒的用途钒主要用于钢铁工业炼制各种合金钢。大量用于制造各种切削工具、锻压模及发电机、船舰、飞机、坦克等各种机器部件,并用于国防尖端工业。由于远距离输送天然气和石油需要高强度钢管线,含钒低合金钢的
Vanadium is a high melting point rare metal, with a silver-gray gloss. As early as 1801 found in lead mines in Mexico, 1905 for the first time applied to industry. Since vanadium can improve the properties of steels, it has become an indispensable component of some steels in recent years. With the development of industrial technology, the demand of vanadium will increase day by day. 1. The use of vanadium Vanadium is mainly used in the steel industry refining a variety of alloy steel. A large number used in the manufacture of various cutting tools, forging dies and generators, ships, aircraft, tanks and other machine parts, and used in defense cutting-edge industries. As the long-distance transmission of natural gas and oil need high-strength steel pipelines, vanadium low-alloy steel
