Description
Technical field
The present invention relates to a kind of primary magnesium ingot standard spectrum sample and preparation method thereof, belong to the manufacturing field of alloy.
Background technology
Magnesium and magnesium alloy are the minimum structural metallic materials of density, and its specific strength is higher than steel, and have good antifatigue and damping performance.Therefore, be used to make transport facility and the Aero-Space parts have special significance.Country attaches great importance to the development and the development of magnesium and magnesium alloy, and State Council has classified the development of magnesium and magnesium alloy materials as one of the Tenth Five-Year Plan (2001-2005) main project of national economy and social development.
As a kind of development of new material, be unable to do without the chemical composition analysis check, and chemical composition analysis be unable to do without standard model.We can say that the development of standard model is an a kind of fundamental research of development of new structural metallic materials.Southwestern Aluminum (group) company limited had developed MgAlMn, MgAlZn, three serial magnesium alloy standard models of MgAlSi in 2002, had satisfied above-mentioned needs well.But because the development of magnesium material is very fast, many new materials constantly are developed, and all need corresponding standard specimen.Therefore, magnesium standard specimen breach is very big, can not adapt to the demand for development of country, Chongqing City's magnesium industry far away, also has many standard specimens suddenly to wait to develop.
Reach reasons such as safety technique owing to the magnesium chemical activity by force, determined that magnesium and magnesium alloy standard specimen development difficulty is more much bigger than aluminium standard specimen.Technical difficult points is as follows:
(1) ingot casting easily produces slag inclusion, and some element casting yield alters a great deal, and is restive, and especially micro-Pb, elements such as Ti, Ni are difficult to add in the magnesium; And easily segregation such as Fe, Ti, Mn, Pb etc.
(2) chemical constitution is adjusted difficulty: because no suitable standard specimen can't be formulated the on-the-spot sample analysis rules, bring very big difficulty for adjustment standard specimen ingot casting chemical constitution.In addition, Pb, Zn, three elements of Ti (generally not requiring), former remelting does not require analysis with magnesium ingot.And Pb, Zn, three elements of Ti have been increased in the new standard primary magnesium ingot standard.
3. safety related technical problems: the chemical activity of magnesium is very strong, in molten condition, very easily with oxygen, nitrogen and water generation chemical action.At bath surface as strictly protection, very fast oxidizing fire just during near 800 ℃.In technological process, liquid metal is directly met water and is just produced the blast of splashing property, must strictly note.In addition, harmful gas and dust all should be dealt carefully with.
4. pure magnesium standard specimen surface anti-oxidation, anticorrosion problem also are difficult points.
Summary of the invention
The object of the present invention is to provide a kind of primary magnesium ingot standard spectrum sample, to satisfy the needs of alloy production.
