Description
Technical field
The present invention relates to a kind of forcing press that uses pressure head, especially relate to a kind of graphite electrode make-up machine.
Background technology
Characteristic such as that artificial graphite electrode has is high temperature resistant, anti-oxidant, ash content is low is widely used in the electric arc furnaces metal smelt, and the production process of electrode is divided into 4 operations: moulding, roasting, graphitization, machined.
The capital equipment of molding procedure is a shaping machine.
Extrusion formation equipment mainly is a large press, and at present, the press of domestic maximum is 4000 tons, and the product maximum gauge of its moulding is 750mm; And equipment price costliness.If produce the big again electrode of diameter, press will be above ten thousand tons.
Along with the development of technology, the especially progress of silicon smelting technique, the small dimension electrode can not satisfy the requirement of smelting.Vibration moulding equipment can be produced big specification electrode, and equipment investment is less, is the first-selection of producing big specification electrode.
Another kind of former is a vibrating forming machine, and is heavy though the structure of traditional vibrating forming machine is fairly simple, and energy resource consumption is big, and the product quality homogeneity is poor.
The pressure of existing pressurization mainly produces by weight, though adopt tens tons weight, also can only produce the pressure of several kg, and its specific pressure generally is 3～4kg/cm
2Secondly,, increased the load of platform greatly, wasted a large amount of energy owing to mould, frame, weight etc. all place on the shaking platform.In addition, because the eccentric stiffener of vibration places below the platform, its bearing maintenance capacity is very big again, has therefore increased considerably the difficulty of flight-line maintenance.Simultaneously, owing to the reasons such as shape of mould, therefore realize that vacuum forming is very difficult, even vacuum equipment is arranged, its vacuum is also very low; Because mould places above the platform, form the goods bottom and bear the machine power of shaking, pressure is born at the goods top, and therefore the difference of Yin Li and intensity cause the power of shaking of machine up and down of goods to differ bigger, and the homogeneity of extrudate density is poor.
Chinese patent CN1353566 discloses a kind of big specification hollow graphite electrode moulding process, and adopting petroleum coke, coal tar pitch, graphite powder is raw material, through stirrings of heating, reinforcedly also shake in advance, depanning behind the pressurization and vibration, cooling, make the electrode base.Because the electrode blank molding is good, the yield rate that later operation is improved product has very great help.Mould includes mould tube, chassis, central tube and gland, and the mould tube includes inside and outside wall, air inlet faucet and the water inlet tap of giving vent to anger.The big specification hollow graphite electrode good conductivity, power saving, the consumption of electrode that adopt this invented technology and mould to produce are little, of many uses.
Summary of the invention
The object of the present invention is to provide a kind of graphite electrode make-up machine.
The graphite electrode of described graphite electrode make-up machine is meant the graphite electrode that is of a size of ф 820～1400mm.
The present invention is provided with electrode dolly, vacuum system, hydraulic system, electric-control system and frame, also is provided with rubber spring support, mould, seaming chuck, cool material system, top dolly, stem stem and centre frame, switching mechanism, push-down head and vibrating motor.
The rotating shaft of mould is located on the rubber spring support, the thickener outlet of cold material system connects mould through belt feeder, seaming chuck is connected with mould with push-down head, the top dolly is located on the track of frame, and seaming chuck, stem stem and centre frame are located on the dolly of top, and vibrating motor is as vibration source and be located at the mould both sides, vibrating motor is arranged at the middle part of graphite electrode, be equipped with on seaming chuck and the mould and be connected tooth, be connected with mould after 15 ° of the seaming chuck rotations, push-down head is fixedly mounted on the bottom of mould; Switching mechanism is connected with cool material system.
Described cool material system adopts the rotating disk cooler.
Described vibrating motor can be located at the middle part of mould, makes the machine power of shaking more even in the axial distribution of shaped electrode.
Described electric-control system can adopt programme-control treatment circuit (PLC), so whole operation can be controlled the realization operation automation by PLC.
Compare with existing graphite electrode former, the present invention has following outstanding advantage:
1) the present invention is particularly useful for the moulding of large-size graphite electrode.Vibration source is arranged at the middle part of electrode, makes the machine power of shaking even in the axial distribution of electrode, and the tap density difference of electrode is little, and bulk density is more even.ф 800～1100mm graphite electrode for example, vibrating motor places the middle part of mould, makes the machine power of shaking more even in the axial distribution of shaped electrode; Super-huge electrode for greater than ф 1200～1400mm then adopts shaking platform, and at this moment shaking platform places the middle part of mould, the vibration source that adopts zero amplitude to start.
2) specific pressure of article of manufacture is far longer than common make-up machine.Adopt two-way pressing mode, the density of electrode is improved greatly and more even.Specific pressure 3～the 4kg of common make-up machine, this equipment specific pressure is brought up to 20～30kg.
3) realize the high vacuum in the production process, satisfied the requirement of technology, stopped the implosion of electrode, improved the casting yield of electrode.Because mould and last push-down head link together, and adopt the measure of sealing, therefore can realize the vacuum of mould inside, vacuum is reached-0.93MPa.
4) because electric-control system can adopt the programme-control treatment circuit, so whole operation can be controlled the realization operation automation by PLC.
5) energy savings.Because the both sides that the employing vibrating motor is hung on the mould tube as vibration source, have therefore been removed shaking platform from; Employing system internal force pressing mode has been removed frame from; Heavy weight has been removed in the pressurization of employing oil cylinder from.Make the weight that participates in vibration reduce 50% approximately, reduced the consumption of electric power significantly.
Through test, the production qualification rate of graphite electrode reaches more than 95%, is greatly improved than the qualification rate (about 80%) of general make-up machine; The bulk density of graphite electrode reaches 1.73g/cm
3, than graphite electrode (about 1.68g/cm of general make-up machine production
3) also be greatly improved.
