钽具有高熔点、耐腐蚀、加工性能好等特点,广泛应用于化工、电子、航空航天等领域。国内生产钽合金板材的生产由于受设备和技术的限制,目前只能生产宽度小于1000 mm,长度小于2000 mm的板材。小尺寸板材会造成使用过程中产生焊缝较多的现象,易使其在长期使用过程中出现破裂失效的情况,造成较大经济损失。本文主要完成了大尺寸纯钽板材的试制工作,摸索了大尺寸纯坦板的制备工艺,制作出了宽幅达1300 mm,长度大于2000 mm的大规格钽板,解决了生产大尺寸纯钽板材的加工技术问题。
Tantalum has high melting point, corrosion resistance, good processing properties and other characteristics, widely used in chemical, electronics, aerospace and other fields. Domestic production of tantalum alloy sheet Due to equipment and technical constraints, currently only the width of less than 1000 mm, the length of less than 2000 mm plate. Small size of the plate will result in the use of more welds generated during the phenomenon, easy to make it appear in the long-term use of the case of rupture failure, resulting in greater economic losses. This paper mainly completed the trial production of large-size pure tantalum plate, groping the preparation process of large-size pure plain plate, produced a large size tantalum plate up to 1300 mm in length and 2000 mm in length, solved the problem of producing large-size pure tantalum Plate processing technology issues.
