Abstract
The invention discloses an electrode hoisting system for an LF furnace. A hoisting supporting beam is arranged on a movable hood of the LF furnace; an electric block track is arranged on the hoisting supporting beam; an electric block is mounted on the electric block track through a driving mechanism; the electric block track is horizontally arranged above the movable hood of the LF furnace and extends out of the horizontal range of the movable hood of the LF furnace. When the technical scheme is adopted, the replacement and regulation of an electrode are performed independently. The movable hood has a self-prepared electrode hoisting equipment, so the regulation and replacement of the electrode are performed by the system independently without interfering with other steps and exerting any influences on other steel making processes. By fully utilizing the space and advantage of the conventional equipment, the transmission of the movable hook and actual needs are combined organically; and thus, the electrode can be hoisted forth and back freely, time is saved, the effective cooperation in operating space is realized, and production efficiency is improved.
