Product Description 2200 degree vacuum directional solidification furnace for Monocrystalline silicon with automatic crucible retrieving system Product DescriptionThe directional solidification furnace is a new type of vacuum furnace that uses the principle of medium frequency induction heating to sinter high melting point metals, cemented carbide, silicon carbide ceramics and other materials under vacuum or protective atmosphere conditions. The equipment usually has a vertical furnace structure, including a furnace body, a heating sensor (graphite or resistance is selected as the heating element), a heating and insulation layer, a directional crystallizer and a mobile lifting mechanism, an operating platform, an inflation system, a power supply and a control system. Vacuum system and other components.The working principle of the directional solidification furnace is to gradually solidify the material into a material with a specific crystal structure by controlling the temperature gradient and crystal growth rate. For example, a single crystal growth furnace is a directional solidification furnace used to produce single crystal materials, while a polycrystalline growth furnace is used to produce polycrystalline materials. These materials have different crystal structures and properties and are widely used in aerospace, optoelectronics, semiconductor, construction, automotive, electronics and other industriesDirectional solidification furnace application scenarios:Preparation of single crystal materials: Directional solidification furnaces, especially single crystal growth furnaces, are used to produce single crystal materials. Single crystal materials have excellent mechanical and electrical properties and are widely used in aerospace, optoelectronics, semiconductors and other fields.Preparation of polycrystalline materials: The polycrystalline growth furnace is a directional solidification furnace for manufacturing polycrystalline materials. Polycrystalline materials are composed of multiple crystal grains, and there are grain boundaries between the grains. The grain boundaries have a certain impact on the properties of the material. Polycrystalline materials are widely used in construction, automobile, electronics and other industries.Preparation of high-quality castings: The VIM series vacuum directional solidification furnace can produce high-quality castings with special structural structures such as turbine engine blades and gas turbine turbine blades. These castings have important applications in aerospace and other fields.Annealing and brightening and degassing metals: Directional solidification furnaces can also be used to anneal, brighten and degassing metals to improve their properties and appearance.Preparation of special materials: Depending on the structure and purpose, the directional solidification furnace can also be used to produce special materials such as single crystal or polycrystalline silicon, sintered ceramics or glass.Technical parameters of directional solidification furnace:Detailed technical parameters:Vacuum induction melting furnace product name2200oC directional solidification furnaceProduct numberCY-IV500-25KW-SS-DXadvantageThis equipment can be used as a directional solidification furnace or vacuum melting.

The inner side of the carbon felt is a layer of bright tantalum sheet, which can reflect heat back to the heating element. The inner side of the tantalum sheet is a tungsten heating element, and a crucible is placed in the heating element. The crucible is installed on the directional solidification rod. The heating element is heated by induction. There is a temperature gradient field between the heating element and the cooling pool. After the material in the crucible is heated and melted, it slowly descends with the directional solidification rod. The molten material drops evenly in this In the temperature gradient field, the crystal lattice rearranges and solidifies in a certain order, forming an ordered crystal.Directional solidification mechanismDirectional solidification stroke and speed can be controlled through the left touch screen, the speed range is 0.1μm/s~2000μm/sCan a water-cooled crucible be connected to the vacuum chamber? okObservation window size Dia 90mmVacuum unit Unit input voltage380V /220VbellowsKF40X1000Vacuum flapper valveKF40Front machine vacuum pump BSV30power0.75KWVoltage380VRotating speed1450rpmAir intake diameter KF25/KF40Front pump pumping rate (L/S)8ultimate pressure5X10 -1Pa Composite vacuum gauge Composite vacuum gauge modelZDFpower supply 220V 55Wcontrol precision± 1%Vacuum gauge measuring range10-5 -10 5 PaSecondary pumpfor molecular pumps(Option One)Molecular pump(The vacuum degree of the cavity can be pumped to 6X10E-4Pa)Molecular pump model FJ620Input voltage 220VMolecular pump air inlet flange DN160Molecular pump pumping rate L/S (to air) 600Molecular pump ultimate pressure (Pa)6×10-7cooling method water coolingCooling water pressure (MPa) 0.1-0.2Cooling water temperature<25oCambient temperature0~40oCRecommended starting pressure<10Pa The secondary pump is a diffusion pump (Option II)diffusion pumpThe vacuum degree of the cavity can be pumped to 5X10E-3Pa)Voltage220Vpower1000WUltimate vacuum degree (when there is no leakage) 10E-5PaAir intake interfaceDN150Air outlet interfaceDN40Amount of oil injected0.3LPumping rate (N2)1000L/S Water cooler (optional) power supply3PH-380V/50HZ Maximum lift 40M Maximum flow16L/min Water tank capacity 60L Refrigeration capacity103Kcal/h water inlet and outlet Rp1/2''Machine size1150×520×1145(LXXXH)Product pictures of vacuum directional solidification furnace:Founded in 2005, Zhengzhou CY Scientific Instrument Co., Ltd. is a company specializing in the development and production of laboratory technology research equipment.
