用粉末冶金方法,利用钛冶金生产产生的废料和低品级的海绵钛制造零件,在经济上是合算的。本工作的目的,旨在对用磨碎TΓ-TB海绵钛废料的方法得到的钛粉的性质进行研究和比较。将+2.5—(-6.0)和+5.0—(-12.0)毫米的65公斤海绵钛废料在直径0.7米,长1米的球磨机中磨碎。为了防止金属在磨碎过程中氧化和着火,采用由食盐配成的粒状防护 The powder metallurgy method, the use of titanium metallurgy waste produced and low-grade titanium sponge titanium parts manufacturing, is economically cost-effective. The purpose of this work is to investigate and compare the properties of titanium powders obtained by the method of grinding T-TB titanium sponge scrap. 65 kg of sponge titanium scrap of +2.5 - (- 6.0) and +5.0 - (- 12.0) mm were ground in a ball mill of 0.7 m in diameter and 1 m in length. In order to prevent oxidation and ignition of the metal in the grinding process, granular protection formulated with salt
