Problems solved by technology

However, the production and processing technology level of my country's existing molybdenum-based materials, whether it is process technology or equipment capabilities, whether it is product performance or variety structure, has a large gap with the world's advanced industrial countries; especially in the preparation and sintering of high-quality slabs. The gaps in temperature control, rolling equipment capacity, rolling process control, rolled material surface quality, and plate specifications and varieties are even greater, which are far from meeting the needs of the rapid development of my country's national economy. As a result, many molybdenum-based plates have to be imported in large quantities.
[0004] At present, there are many enterprises engaged in the R&D and production of molybdenum-based alloy sheets in my country, but there are few enterprises with complete process routes and complete production process equipment and facilities. There are obvious gaps in the rationality of alloy ratio, homogeneity and purification of billets, sintering process arrangement and temperature control, rolling process arrangement, plate quality and specification varieties, etc.

Abstract

The invention relates to a process for manufacturing the molybdenum based rare earth alloy plate and equipment for manufacturing the same, wherein pure molybdenum powder is simultaneously added with four rare earth oxides of ZrO2, Y2O3, La2O3 and Nd2O3 according to certain ratio, by utilizing the chrematistics of long and large crystal grain and strong sag resistance and anti-creep property of rare earth alloy elements and the dispersion strengthening function, the re-crystallization temperature of the metal molybdenum is increased, the mechanical performances of the molybdenum based material such as tensile property, yielding behavior and extensibility are improved, and the application range of the molybdenum based material is widened; and the manufacturing process comprises production procedures of material preparation treatment, mixing treatment, forming treatment, sintering treatment, material making treatment and the like and the setting of various technical parameters of special technical equipment and process. With the preparation process, the molybdenum based rare earth alloy plate which has the advantages of good electric conductivity and heat conductivity, excellent high-temperature resistance and corrosion resistance and better mechanical performances such as tensile property, yielding behavior and extensibility, and fills in domestic blank and can replace the imported material can be manufactured.

Description

technical field [0001] The invention relates to a manufacturing process and equipment for an alloy plate, in particular to a manufacturing process and equipment for a molybdenum-based rare earth alloy plate. Background technique [0002] Molybdenum-based materials are widely used in electronics, electric power, aerospace, automobile, metallurgy and other production industries because of their unique high melting point, good electrical conductivity, thermal conductivity, superior corrosion resistance, and radiation resistance. With the continuous improvement of my country's scientific and technological level, high-tech products in various production fields are constantly emerging, the application fields of molybdenum-based materials are expanding day by day, and the number of demand and use is increasing sharply. Higher and higher. However, due to the low recrystallization temperature of molybdenum and its brittleness after recrystallization, it is difficult to process and ma...
