Summary: | The utility model relates to a suspension type segregating carburization frame special for a drill rod, which comprises a carburization support (4) and is characterized by further comprising a suspension disc (1). The suspension disc (1) is arranged above the carburization support (4) and capable of rising and falling freely, and a through hole (3) is arranged on the suspension disc (1). The suspension type segregating carburization frame enables a carburization layer of a carburization process drill rod and a carbon potential to be even and leads the drill rod to be free of deformation and bend, operation of discharging from a furnace and hanging on a hook under a high temperature condition are easy, a drill rod straightening processing process is saved, so that the segregating carburization frame improves work efficiency and is suitable for a carburization process of the drill rod ranging from 1.1m to 4.0m. |
