The conductive automatic clamping device is characterized by comprising an auxiliary electrode, a conductive material rod, a fixing shaft, thin film air cylinders, a fixing board and a marble, wherein the conductive material rod is connected to the auxiliary electrode through the marble; the fixing shaft and the fixing board are fixedly arranged on a furnace head bracket; the fixing shaft is arranged on the outer side of the conductive material rod; and a vertical moving sleeve consists of the conducive material rod and the three thin film air cylinders. 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 up of support arm, column, short net, X-former, holder ingot chassis etc.Traditional single column props up arm-type, two column rotation arm-type double electroslag furnace, and support arm clamp holder clamping dummy electrode and metal electrode, control transmission mechanism rotate T type screw mandrel drive roller cantilever and move up and down the completion 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.Be prone to 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 possibly appear in the electrode welding process welding in addition; Under the situation of big packing ratio, be difficult to adjustment metal electrode position in the horizontal direction, be difficult to make metal electrode to be in the center of mold all the time.Metal electrode and mold are prone to beat arc, even have the phenomenon that punctures mold 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; Jacking bar slip Ceramic Balls group forced locking device in the water-cooled that it is power that its purpose is intended to design three diaphragm cylinders solves the large-scale consutrode 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 through hoodle, and stationary shaft and retaining plate are fixed on the burner support, and the conduction material bar outside is a 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 interior jacking bar slip Ceramic Balls group forced locking devices of water-cooled that diaphragm cylinder is a 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).
