Automatic furnace cover closing device suitable for vacuum melting furnace

Abstract

The invention discloses an automatic furnace cover closing device suitable for a vacuum melting furnace. The automatic furnace cover closing device comprises a furnace cover body, a moving device and a control device. The moving device comprises a trolley frame, a driving wheel set, a driven wheel set, a rectifying mechanism, a lifting mechanism and a power mechanism. The driving wheel set and a power mechanism are arranged at one end of the trolley frame. The power mechanism is in transmission connection with the driving wheel set. The other end of the trolley frame is provided with the driven wheel set. The portion, between the driving wheel set and the driven wheel set, of the trolley frame is provided with the rectifying mechanism. The lifting mechanism is arranged in the center portion of the trolley frame. A furnace cover is arranged below the lifting mechanism. The lifting mechanism is movably matched with the furnace cover. The lifting mechanism and the power mechanism are both electrically connected with the control device. The automatic furnace cover closing device is stable and reliable in operation performance, long in service life, convenient and fast to repair and maintain and low in fault rate, the technical defects that existing equipment cannot work stably in the high-intensity magnetic field, and is unstable in operation, and inconvenient and not fast to repair and maintain are overcome, requirements of practical production are met, the production efficiency is effectively improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of metallurgical equipment, and in particular relates to an automatic closing device for a furnace cover suitable for a vacuum melting furnace. Background technique [0002] The vacuum melting furnace is generally composed of a furnace cover, a furnace body, a vacuum system, and a power control system. The furnace cover is equipped with electron beam guns, electron generators, pipeline cables and other equipment. The existing one uses a motor to drive the furnace cover. Due to the vacuum When the smelting furnace is working, it will generate a strong magnetic field. The strong magnetic field will easily interfere with the operation of the motor, resulting in unstable operation when the cover is opened and closed, and the impact and vibration between the furnace body and the furnace cover will be large. Equipment such as cables are easily damaged by shock. [0003] Therefore, it is ...
