Description
Technical Field
The utility model belongs to the field of metal materials, and particularly relates to a master alloy quality control splitter plate of a vacuum induction furnace.
Background
The high-temperature alloy is mainly applied to the fields of aerospace, gas turbines and the like, and is a top-grade industrial material standing from a pyramid tip. The high-temperature alloy is mainly used for the industry service of aerospace gas turbines in the material industry, and is widely applied to the industrial fields of electric power, petroleum and petrochemical industry, automobiles, metallurgy, glass manufacturing, atomic energy and the like due to the excellent performances of high temperature resistance, corrosion resistance, fatigue resistance, creep resistance and the like.
The high-temperature alloy casting master alloy is manufactured by the working procedures of refining through a vacuum induction furnace, shunting and pouring a refractory material into a mould for solidification and the like. The quality of the master alloy is crucial to the performance of the final cast part product, and the vacuum melting and pouring solidification process is a key link of the high-temperature alloy preparation process. The quality of the high-temperature alloy master alloy can directly influence the subsequent treatment process and has important influence on the final performance of the high-temperature alloy product. Alloy smelting is a key link for obtaining a high-temperature alloy product with excellent performance and meeting working conditions. The purpose of superalloy melting is to eliminate inclusions larger than the critical defect size, and most of the non-metallic inclusions are produced during master alloy melting, and the quality of the superalloy ingot is poor, and reliable cast parts cannot be produced. Under the condition of certain components, a proper production process needs to be selected, and segregation, purity and the like of the alloy are controlled, so that the high-temperature alloy product meeting the performance requirements can be prepared finally. The cast high-temperature alloy refers to that master alloy is directly cast into parts such as a turbine disc or a blade and the like after being remelted in vacuum smelting. The cast high-temperature alloy is also an important material in aerospace, energy, transportation and chemical industries, and in the vacuum induction smelting process, the control of high-temperature high-vacuum and pressure conditions in the refining period, the control of the addition amount of alloy elements in the alloying period and the selection and adjustment of casting temperature in the casting period, particularly the degassing, turbulence, flow distribution, flow velocity distribution, feeding distribution and the like in the process of redistributing and casting the master alloy rods can influence the performance of the cast high-temperature alloy. The cast high-temperature alloy has a wide composition range and is divided into three types according to the use temperature: isometric crystal casting high-temperature alloy used at-253-650 ℃; isometric crystal casting high-temperature alloy used at 650-950 ℃; and directionally solidifying columnar crystal casting high-temperature alloy used at 950-1100 ℃. Taking an aircraft engine case as an example, the main material is an equiaxed high-temperature alloy casting used under medium and low temperature conditions, the development trend is complicated in structure, precise in size and thin-wall and light-weight, and therefore the core difficulty of the process technology is the cooperative control of precise forming and solidification structures. The master alloy is called "master alloy" because it is a casting base metal and has strong genetic properties, that is, many characteristics of the master alloy (such as carbide distribution, grain size, microscopic mirror structure, and even many characteristics affecting the quality of a casting product including mechanical properties) are inherited to the casting after the master alloy is cast by remelting.
For the international standard of the master alloy, with the improvement of the technical standard requirements at home and abroad, the master alloy rod is not allowed to have air holes, shrinkage cavities, impurities, surface defects and the like, and the purity requirement is higher and higher. Such as: the requirements of American space navigation standards are not easy to be met by domestic manufacturers, and the enterprise standards such as GE, RR and the like are stricter. The technical standards can be achieved only by controlling the raw material link and the refining link and controlling the casting link. At present, the master alloy bar is cast by adopting a splitter plate, and the conventional splitter plate structure has the center casting surrounding equal-division splitter plate, a one-way runner casting splitter plate and other types. For the two shunting plate structures, the problems of gas entrainment, segregation, shrinkage cavity, inclusion, surface defects and the like of the master alloy rod, particularly the rear-end master alloy rod, caused by nonuniform shunting of the master alloy melt can be solved, and the international product standard can not be met.
