Abstract: The present application discloses a crystal rod manufacturing method and a crystal rod belonging to a field of monocrystal growth technologies. The crystal rod manufacturing method of the present application includes a shoulder rotation step and a diameter equalization step, wherein in the shoulder rotation step and/or the diameter equalization step, hydrogen-containing gas is inputted. The hydrogen-containing gas includes hydrogen gas, a mass of the hydrogen gas is mH, a total mass of the hydrogen-containing gas is mtotal, an inequation as follows is satisfied: mH/mtotal?30%. The present application, by inputting the hydrogen gas during the process of manufacturing the crystal rods, can lower an oxygen content of monocrystals to reduce defects in the monocrystalline silicon, which can reduce formation of boron oxygen complexes and prevent a phenomenon of efficiency degradation when boron-doping monocrystals are pulled.

Abstract: A suspended lifting device for diversion cylinder is provided, wherein the suspended lifting device includes a lifting beam connected to a surface of a water-cooling cross arm. A groove is provided on the lifting beam, and the groove is configured to receive a lifting bolt. A positioning plate is disposed on a bottom side of the lifting beam close to the water-cooling cross arm, and the positioning plate is configured to control an angle between the lifting beam and the water-cooling cross arm.

Abstract: The present disclosure provides a flow guide cylinder lifting assembly, including a flow guide cylinder lifting component disposed on a water-cooling lateral arm and a lifting bolt, wherein the lifting bolt is disposed in the flow guide cylinder lifting component, a lower end of the lifting bolt extends downward through an opening of an upper heat-insulating cover of the flow guide cylinder, a lifting nut is disposed at an upper end of the lifting bolt, and the lifting nut is matched to the lifting bolt to raise or lower the flow guide cylinder.
