During initialization, bell promotes and rotating mechanism 6 drives the top that bell rotates to body of heater 4, descend and be placed on the body of heater 4, simultaneously, bell lifting and rotating mechanism 6 also drive three electrodes of electrode lifting mechanism 8 connections and are rotated in place simultaneously, to electrode power supply, electrode lifting mechanism 8 drives three electrodes and descends to being deep in the body of heater 4 and begin steel-making with the furnace charge starting the arc by conductive cross arm for power pack 1; After steel-making finished, electrode lifting mechanism 8 was mentioned three electrodes, and tilting mechanism 3 is poured out the molten steel in the body of heater 4 and is used to be cast into ingot casting or steel casting.The shortcoming that exists on the electric furnace arrangement for producing steel structure of this kind structure is: be to serve as the parts of connection drive bell 5 with two crossbeams 61 in bell lifting and the rotating mechanism 6, article two, crossbeam 61 is across on bell 5, and and have two point of fixity between the bell 5, occupied on the bell 5 very large space thus, the space of maintenance, operation is diminished, seriously hindered the layout of other parts on bell 5, as the layout of the 4th hole smoke evacuation bend pipe, the 5th hole charging mechanism etc.
Summary of the invention
The purpose of this utility model be for solve that bell that existing electric furnace arrangement for producing steel exists promotes and rotating mechanism in two crossbeams occupied space very big on the bell, the problem that has hindered other parts on bell, to arrange, and provide the space that a kind of bell promotes and rotating mechanism occupies on the bell little, help the electric furnace arrangement for producing steel that other parts are arranged on bell, as the layout of the 4th hole smoke evacuation bend pipe, the 5th hole charging mechanism etc.
The utility model is by power pack, base fascinates, tilting mechanism, body of heater, bell, bell promotes and rotating mechanism, electrode, electrode lifting mechanism, wherein tilting mechanism is positioned on the support, body of heater places on the tilting mechanism, bell can be placed on the body of heater, bell is fixed on the below of bell lifting and rotating mechanism, three electrodes vertically are set in the body of heater from bell versatilely and also can rise or descend, power pack by the conductive cross arm in the electrode lifting mechanism to three electrode power supplies, three electrodes are fixed on the conductive cross arm in the electrode lifting mechanism, can drive and rising or decline by electrode lifting mechanism, electrode lifting mechanism promotes with bell and the rotation of rotating mechanism consubstantiality, characteristics of the present utility model are that bell promotes with bell with a connecting arm and rotating mechanism is connected.
During the utility model initialization, bell promotes and rotating mechanism drives the top that bell rotates to body of heater, descend and be placed on the body of heater, simultaneously, bell lifting and rotating mechanism also drive electrode lifting mechanism and are rotated in place simultaneously together with three electrodes, power pack admittance electricity transverse arm is to electrode power supply, and three electrodes of electrode lifting mechanism drive descend to being deep in the body of heater and begin steel-making with the furnace charge starting the arc; After steel-making finished, electrode lifting mechanism was mentioned three electrodes, and tilting mechanism is poured out the intravital molten steel of stove and is used to be cast into ingot casting or steel casting.
The beneficial effects of the utility model are:
Because of bell is connected with bell lifting and rotating mechanism with a connecting arm, the space that bell promotes and rotating mechanism occupies on the bell is little, helps other parts and arranges on bell.
