我国穿制无缝不锈钢管用的顶头,目前大都采用铸态钼合金顶头。这种顶头不但成本高,钼消耗大,而且平均穿管寿命仅在100支左右,生产效率很低。为改变这种落后状况,在无产阶级文化大革命和批林批孔运动推动下,株洲硬质合金厂与北京钢铁研究院和大冶钢厂协作,以TZM为基础,开展了粉态钼顶头的研制工作。通过多种成份的摸索和使用试验,目前以Ti 0.6～0.8％,Zr 0.1
China wear seamless stainless steel pipe with the head, most of the current use of molybdenum alloy head. This head not only high cost, molybdenum consumption, and the average wear tube life of only about 100, the production efficiency is very low. In order to change this backwardness, Zhuzhou Carbide Plant, in collaboration with Beijing Iron and Steel Research Institute and Daye Steel Works, promoted by the Great Proletarian Cultural Revolution and the Punch Hole Campaign, carried out the production of molybdenum molybdenum head based on TZM Development work. Through a variety of ingredients to explore and use the test, the current Ti 0.6 ~ 0.8%, Zr 0.1
