本文简述了用挤压轧制法制取钼管的工艺流程。其中试验了粉末冶金、二次真空电孤熔炼、一次电子轰击再真空电弧炉重熔和两次电子轰击坯锭,并作了初步的评价。在三辊轧管机上采用氢气——压缩空气火焰的加热法轧制出了外径8～21毫米、壁厚0.3～1.5毫米、长2米左右的各种规格钼管,证明焰气加热法是可行的,并初步认定有利于钼管轧制的工具孔型。
This article describes the extrusion process with molybdenum pipe manufacturing process. Among them, the tests of powder metallurgy, secondary vacuum arc soldering, primary electron bombardment and vacuum electron arc furnace remelting and two electron bombardment of billets were carried out. Preliminary evaluations were made. In the three-roll mill on the use of hydrogen - compressed air flame heating method of rolling out the outer diameter of 8 to 21 mm, wall thickness of 0.3 to 1.5 mm, length of about 2 meters of various specifications molybdenum tube, flame gas heating method Is feasible, and initially identified conducive to the molybdenum pipe rolling tool hole.
