Abstract

The invention provides a rotary two-way telescopic blanking connecting pipe device and an application method. The device comprises a two-way telescopic blanking connecting pipe, a rotary device and a base, wherein the middle part of the two-way telescopic blanking connecting pipe is connected to the rotary device; the rotary device is arranged on the base; and a limit switch is arranged on the base. When the device rotates to a standby position, equipment maintenance and replacement can be conveniently conducted, the maintenance intensity of the equipment is reduced, and the working efficiency is improved. According to the rotary two-way telescopic blanking connecting pipe device and the application method, the two-way telescopic blanking connecting pipe is rotated to the standby position, and then a feed opening is sealed by a cover plate at the feed opening of a vacuum tank, so that an RH device can still conduct some cyclic degassing light treatment or conduct baking and slagging operation under the condition of not moving the tank, the production rhythm can be effectively ensured, the benefit is improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of vacuum alloy feeding of an RH molten steel vacuum refining system, and in particular relates to a rotating bidirectional telescopic feeding connecting pipe device and a use method thereof. Background technique [0002] In the RH molten steel vacuum refining system, in order to meet the quick connection and disconnection of the vacuum tank system and the vacuum alloy feeding system, an alloy expansion joint is specially set up. The expansion joint consists of a compensator, three cylinders and two upper and lower flanges. . The usual setting method is: the upper flange of the expansion joint and the lower flange of the discharge chute are fixedly connected by bolts, and the connection / disconnection of the upper flange of the thermal insulation joint of the vacuum tank is realized by the expansion and expansion cylinder of the compensator. The vacuum tank is a container for refining, and its internal refractory mate...
