Technical field
The utility model belongs to technical field of smelting, particularly the open type electrode jaw in a kind of electric furnace rise fall of electrodes system.
Background technology
Electrode jaw is the vitals of electric furnace, the function of undertaking being connected between large currents combination electric conductor (hereinafter referred to as short net) and electrode, electric energy transmitting, holding electrode tightly and frequently moving up and down.Because traditional electrode clamper is the ring of a sealing, promote a jacking block by cylinder electrode is held tightly, its advantage is simple in structure, easy to process, thereby is widely adopted.But its shortcoming is also very obvious: one, large electric current enters the process of electric furnace through this clamper electrode of flowing through again from short net, the ring (clamper) of this sealing is just equivalent to install a coil on electrode, and the induction reactance that it produces can increase along with the increase of electric current.Two, because the function of jacking block is only to withstand electrode, do not have the function of conduction, therefore, this electrode jaw can only be one side conduction, and contact resistance is larger, and in hot environment, this contact resistance can be larger.
Utility model content
In order to overcome above-mentioned defect, reduce induction reactance and the contact resistance of electrode jaw, the purpose of this utility model is to provide a kind of simple in structure and open type electrode jaw that temperature rise is lower.
A kind of open type electrode jaw, this electrode jaw is mainly made up of mobile soft copper paper tinsel upper junction plate, the fixing semicircle of electrode jaw, the movable semicircle of electrode jaw, mobile soft copper paper tinsel lower connecting plate, the movable semicircle pushing mechanism of electrode jaw, cylinder push-rod, electrode jaw lifting transverse arm, the movable semicircle bearing pin of electrode jaw; Described mobile soft copper paper tinsel upper junction plate, mobile soft copper paper tinsel lower connecting plate, the fixing semicircle of electrode jaw, the movable semicircle of electrode jaw are hollow structure, mobile soft copper paper tinsel upper junction plate and electrode jaw are fixed semicircle, the movable semicircle of electrode jaw and mobile soft copper paper tinsel lower connecting plate tighten together by welding, in its cavity, are equipped with welding diaphragm; The movable semicircle of described electrode jaw is connected with electrode jaw lifting transverse arm, the movable semicircle pushing mechanism of electrode jaw simultaneously, and rotates around the movable semicircle bearing pin of electrode jaw being fixed on electrode jaw lifting transverse arm; After the movable semicircle combination of the fixing semicircle of described electrode jaw and electrode jaw, entirety is carried by electrode jaw lifting transverse arm.The movable semicircle pushing mechanism of electrode jaw is mainly made up of crank and connecting lever, and crank and connecting lever link together by rotating shaft.
The beneficial effects of the utility model are: one, the ring of sealing is originally divided into two semicircles, cuts off electric magnetic circuit, thereby reduced induction reactance by an air gap; Two, divide two-way to import electrode through fixing semicircle, movable semicircle respectively the electric energy of short net transmission, make the one side conduction of traditional clamper become two-sided conduction, increased conductive contact surfaces, reduced contact resistance.
