Embodiment Construction

[0014] exist figure 1 , 2 In 3, a transitional connection method between a heating rod and a water-cooled electrode for a crystal furnace, the two ends of the heating rod (2) are processed into an external thread shape; and then one end of the metal rod (1) is set to match the electrode installation position Install the plane, and drill a threaded hole at the position of the installation plane, and the other end is processed into an internal threaded hole matching the external thread of the heating rod (2), and the cross-sectional area of ​​the metal rod (1) is at least that of the heating rod (2). 1.8 times the cross-sectional area. When installing and implementing, first connect the two ends of the heating rod (2) to the corresponding ends of the two metal rods (1), and then fix the other ends of the two metal rods (1) to the water-cooled heater through the threaded holes with refractory screws. At the electrode installation position, a transitional connection between the ...

Abstract

The invention discloses a transitional connection method for a heating rod and a water cooling electrode of a crystal growing furnace. The transitional connection method is characterized in that two ends of the heating rod are respectively connected with a refractory metal rod with a larger cross section, and the refractory metal rods with the larger cross section are fixed with the water cooling electrode. When the transitional connection method is adopted, reliable contact can be ensured, electric clearance can be prevented from arc striking, and the thermal damage to the electrode caused by the direct contact of a thermal load of the high-temperature heating rod with the electrode can also be avoided; and the transitional connection method is applicable to various low-voltage high-power tungsten resistance furnaces, such as a sapphire crystal growing furnace and a monocrystalline silicon crystal growing furnace.

Description

technical field [0001] The invention relates to single crystal growth equipment by melt seed crystal method, in particular to a transitional connection method between a heating rod for a crystal furnace and a water-cooled electrode technical background [0002] Many tungsten wire heating element high-temperature resistance furnaces must be powered by low voltage and high current. Multiple tungsten wire heating elements are connected in parallel to electrodes of two polarities at the same time. The end adopts the method of bundling multiple thin tungsten wires to increase the cross-sectional area of ​​electricity and then install them on the electrodes. This method is not only inconvenient for installation and maintenance, but also easy to cause poor contact due to loosening of the filaments around the heating wire. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned existing technologies, the present invention provides a heating ...
