本发明的粉冶高碳钼合金顶头是通过改变顶头用的钼合金成份研究出相应的烧结工艺及新的顶头加工变形方法,为生产不锈钢管提供一种综合性能优于国内外现有顶头的产品。钼合金顶头是生产不锈钢、耐热钢和轴承钢无缝管材的穿孔关键工具。按生产方法可分为熔炼和粉末冶金两大类,用粉冶法生产钼合金顶头的优点是流程短、工艺简
The powder metallurgy high-carbon molybdenum alloy head is prepared by changing the composition of the molybdenum alloy used for the head to develop the corresponding sintering process and a new method for the deformation of the head machining. The method provides a stainless steel pipe with better overall performance than the prior art at home and abroad product. Molybdenum alloy head is the production of stainless steel, heat-resistant steel and bearing steel seamless pipe piercing key tools. According to the production method can be divided into two major categories of smelting and powder metallurgy, powder metallurgy with the advantage of the production of molybdenum alloy head is a short process, the process of Jane
