2200℃ directional solidification furnace

    The 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

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 industries

Directional 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   solutions

 A protective sleeve is placed on   the induction coil, and the protective sleeve is wrapped with carbon felt to   increase the thermal insulation performance. 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.
