  • High-temperature forming device for imperfect single-crystal wafers used for neutron monochromator
    Patent number: 11753742
    Abstract: A high-temperature forming device for imperfect single-crystal wafers used for a neutron monochromator includes a heating electric furnace, a temperature control system, a die system, a loading system, a vacuum protection system, and an auxiliary system. Where a furnace mouth of the heating electric furnace faces downwards, the heating electric furnace can be lifted vertically or a hearth of the heating electric furnace can be opened and closed. A vacuum protection cavity is formed by a glass cover and a blocking flange, a through hole is formed in one end of the glass cover, and the other end of the glass cover is closed. An operation opening is formed in the glass cover, the die system includes an upper die, a middle die, and a lower die, the middle die is a composite die.
