Description

Arc furnace bell, last furnace shell and following furnace shell are with the three-in-one suspender of double hook type
Technical field
The utility model belongs to metallurgical machinery arc furnace loading and unloading suspender field, the three-in-one suspender of double hook type that particularly a kind of arc furnace bell, last furnace shell and following furnace shell handling are used.
Background technology
Arc furnace is a metallurgical smelting furnace; Molten steel and slag corrosion can cause loss to following furnace shell refractory material in the smelting process; General 300~400 stoves just need to change (handling) and once descend furnace shell; Simultaneously, because the replacing each time and the work such as daily attention of himself of furnace shell down, bell and last furnace shell also must handlings.
The handling of domestic present high capacity arc furnace bell, last furnace shell and following furnace shell is to adopt different modes to distinguish operation with different suspenders.
The handling of bell and last furnace shell normally adopts the separate unit driving to come handling through rope rig.
The handling of following furnace shell has four kinds of modes:
(1) adopt two drivings to lift through shoulder pole girder+steel rope;
(2) adopt two drivings to come handling through shoulder pole girder+following furnace shell special hanger+steel rope;
(3) adopt the separate unit driving to come handling through steel rope;
(4) adopt the separate unit driving to come handling through following furnace shell special hanger+steel rope.
Wherein, the handling mode of (1) and (3) all exists steel rope to furnace shell top generation extruding and wearing and tearing down, and steel rope discontinuity equalization, problems such as the overbalance of body of heater, difficulty in place simultaneously; (1) and the handling mode of (2) under handling, in the furnace shell process, be to adjust the body of heater balance through the different lifting altitude of two drivings, poor synchronization, and can bring that the organization of production difficulty is big, labor strength reaches long difficult problem duty cycle greatly; (2) and (4) though the handling mode adopted time furnace shell special hanger, this suspender must be established special-purpose storage rack, has increased investment.
To sum up, for the bell of accomplishing arc furnace, the handling work of going up furnace shell and following furnace shell, need subsequent use three kinds of suspenders (rope) in the prior art.This has not only increased investment, has taken the limited working space in workshop, has also increased the difficulty of management.Descend furnace shell must establish the special hanger storage rack in addition, also increased investment.
