The conductive automatic clamping device provided by the invention has the advantages that the device for automatically locking by means of using the three thin film air cylinders as power to drive a water cooling inner sleeve material rod to slide a ceramic ball group is designed. The conduction problem, caused by large locking contact current (40000 A) of a large-size consumable electrode and the conductive material rod of the 120-t electric slag furnace, can be solved.
Description
Technical field
The present invention is a kind of electroslag furnace electrodes conduct automatic clamping device, belongs to extraordinary metallurgical equipment technology field.
Background technology
Traditional electroslag furnace generally is made of support arm, column, short net, transformer, holder ingot chassis etc.Traditional single column props up arm-type, two column rotation arm-type double electroslag furnace, support arm clamp holder clamping dummy electrode and metal electrode, and control transmission mechanism rotation T type screw mandrel drive roller cantilever moves up and down finishes melting.Do not establish the protection of inert gas cover.Owing to do not have protection of inert gas, the difficult control of the scaling loss that increases hydrogen, oxygen, nitrogen and easy oxidation element of electroslag steel.Influence the quality of ESR ingot.It is big that roller props up arm-type electroslag furnace mechanical friction coefficient, and control accuracy is low.Easy sleepy head behind the device metal electrode, dummy electrode and metal electrode have increased owing to entire length, inclined to one side dislocation or the not straight phenomenon of weldering also may appear in the electrode welding process welding in addition, under the situation of big packing ratio, be difficult to adjust metal electrode position in the horizontal direction, be difficult to make metal electrode to be in the center of crystallizer all the time.Metal electrode and crystallizer are easily beaten arc, even have the phenomenon that punctures crystallizer to take place.Single station electroslag furnace can not be produced in ESR ingot section cooling time, and big ingot shape ESR ingot is longer cooling time, and production efficiency reduces.
Summary of the invention
What the present invention proposed is a kind of electroslag furnace electrodes conduct automatic clamping device, the water-cooled Inner jacking bar slip Ceramic Balls group forced locking device that it is power that its purpose is intended to design three diaphragm cylinders solves the large-scale consumable electrode of 120t electroslag furnace and contacts big electric current (40000A) conduction problem with the locking of conduction material bar.
Technical solution of the present invention: it is characterized in that comprising supporting electrode, conduction material bar, stationary shaft, diaphragm cylinder, retaining plate, hoodle; Wherein conduction material bar connects on the supporting electrode by hoodle, and stationary shaft and retaining plate are fixed on the burner support, and the conduction material bar outside is stationary shaft, and conduction material bar and three diaphragm cylinders one of the composition that joins moves up and down cover.
Advantage of the present invention:Three water-cooled Inner jacking bar slip Ceramic Balls group forced locking devices that diaphragm cylinder is power have been designed.Solved the large-scale consumable electrode of 120t electroslag furnace and expected that with conduction the locking of bar contacts the conduction problem of big electric current (40000A).

Embodiment
Contrast accompanying drawing, its structure are to comprise supporting electrode 1, conduction material bar 2, stationary shaft 3, diaphragm cylinder 4, retaining plate 5, hoodle 6; Wherein conduction material bar 2 connects on the supporting electrodes 1 by hoodle 6, and stationary shaft 3 and retaining plate 5 are fixed on the burner support, and conduction material bar 2 outsides are stationary shaft 3, and conduction material bar 2 and three diaphragm cylinders 4 one of the composition that joins moves up and down cover.
Form a stationary shaft part by stationary shaft 3 and retaining plate 5, stationary shaft 3 and retaining plate 5 are fixed on the burner support.
The described cover that moves up and down is joined by conduction material bar 2 and three diaphragm cylinders 4 and forms, and under the dynamic action of diaphragm cylinder 4, conduction expects that bar 2 does vertical up-and-down movement outside stationary shaft 3.
Some hoodles 6 have been accepted the effect that connects conduction material bar 2 and supporting electrode 1.
Working process of the present invention: beginning → as shown in 3, centrally aligned supporting electrode 1 center with stationary shaft 3, and descend, contact with supporting electrode → as shown in Figure 1 and Figure 4, diaphragm cylinder 4 piston rods are stretched out, the material bar 2 that will conduct electricity is descending along stationary shaft 3, hoodle 6 is snapped in the neck of supporting electrode 1 → promotes stationary shaft 3 and conduction material bar 2, supporting electrode can be mentioned, transfer to smelt station and smelt → after the smelter finishes and goes to and changes the electrode station, diaphragm cylinder 4 piston rods are withdrawn, to conduct electricity material bar 2 along stationary shaft 3 up → lifting stationary shaft 3 and conduction material bar 2, hoodle 6 is skidded off in the neck of supporting electrode 1, and supporting electrode 1 is thrown off stationary shaft 3 → electroslag furnace electrodes conduct automatic clamping device and is finished a do action.
Be power with the diaphragm cylinder, drive water-cooled Inner jacking bar and slide, and then drive some hoodles, will expect the quick and reliable auto lock of bar and supporting electrode or disengagement.
By being power with the diaphragm cylinder, driving water-cooled Inner jacking bar slides, and then drive some hoodles, to expect the quick and reliable auto lock of bar and supporting electrode or disengagement, thereby the rapidity and the accuracy that provide conduction material bar to be connected with supporting electrode, it is reliable to guarantee that conduction material bar is connected contact with supporting electrode, makes the difficulty that solves existing in prior technology large-tonnage high quality electrode production be achieved.
