浅析钼板坯压制开裂与钼粉性质的关系

Superficial Analysis on the Relation of Molybdenum Slab Pressing Cracking to Molybdenum Powder Characteristics

研究了钼粉原料的种类、粒度、松比及Fe、C、O、Ca含量等因素对钼板坯研制成形的影响。结果表明,控制钼粉粒度和钼粉中Fe、C、O、Ca元素的含量,可以提高钼板坯的压制成形性,确保板坯压制时不致开裂。

The effect of several factors such as kind,fineness,apparent volume and Fe,C,O and Ca contents of raw molybdenum powder on pressing formability of molybdenum slab was investigated. The results show that the pressing formability of molybdenum slab may be improved by the control of fineness and Fe,C,O and Ca contents of the molybdenum powder,thus ensuring the slab against cracking during the pressing.
