Products Description
Because molybdenum and molybdenum lanthanum alloy have the characteristics of high high temperature strength, poor low temperature plasticity, and high temperature oxidation, etc., the rolling equipment requirements for molybdenum and molybdenum alloy plates are high, the rolling process is difficult, the rolling yield is low, and the plasticity of the rolled plates is poor, and the anisotropy is obvious, which leads to the difficulty of further deep processing and forming of molybdenum plates and molybdenum alloy plates, which limits the development and application of high value-added molybdenum products.

1.The ideal rolling process of powder metallurgy sintered molybdenum lanthanum: the billet opening temperature of molybdenum lanthanum is about 1450 °C, the pressing rate of the billet is 30%-40%, the first hot rolling is heated and rolled 5 times, the second fire heating temperature is 1400 °C, and the rolling is 4 times. The pressing rate of hot rolling passes is 20%-30%. The warm rolling and annealing temperatures of molybdenum lanthanum are all high-purity molybdenum. For pure molybdenum and molybdenum lanthanum alloys, cross-rolling was carried out in the warm rolling stage, and the anisotropy of molybdenum alloy plates was improved by cross-rolling, and the commutation points were selected for cross-commutation rolling. The hot-rolled and warm-rolled cross-rolling methods significantly affect the microstructure properties of molybdenum plate and molybdenum-lanthanum alloy plate, and the ratio of transverse and rolling deformation in the warm-rolled cross-rolling process significantly affects the anisotropy of the material. The hot-rolled plate process of molybdenum and molybdenum lanthanum alloy is stable, and the comprehensive yield rate of molybdenum and molybdenum lanthanum alloy reaches 90%.
