The invention relates to a niobium or tantalum strip、tantalum foil production method, in which niobium or tantalum metal billet with thickness of 40~100mm is rolled by medium thick plate method, and when niobium or tantalum sheet is thin, the sheet is welded into a strip and the belt is led by welding before and after rolling, and the finished product with thickness of 0.001~0.5mm is obtained. The invention has the advantages of practicability, strong economy, flexible production and easy realization. It can effectively reduce the investment and production cost of niobium or tantalum strip foil products, improve the production efficiency, yield, structure and mechanical properties, plate shape and surface quality of the products, and fully meet the production process requirements.
Niobium, tantalum foil with good corrosion resistance and high temperature resistance, good strength, impact toughness, plasticity and excellent processing performance and good affinity with the human body, widely used in aerospace, military equipment, photoelectric, communication, superconductivity, medical devices, chemical and textile industry and other high-tech materials, application and development prospects are very broad market.
In view of the production process and equipment status of niobium and tantalum sheet, how to produce niobium and tantalum strip foil in line with market demand is very important under the condition of minimizing equipment investment.
Niobium or tantalum strip foil production method, which is practical, economical, flexible and easy to realize, can effectively reduce the investment and production cost of niobium or tantalum strip foil products, improve the production efficiency, yield, microstructure and mechanical properties, plate shape, surface quality, fully meet the production process requirements; In the case of thin niobium or tantalum plate, the strip is welded into a strip and the strip is drawn by welding back and forward to reduce the equipment investment.
