Description
The present invention relates to electroslag process, relate to special-shaped casts diecasting method and device thereof or rather.
The invention of recommending mainly is applicable to the special-shaped casts of getting ferrous metal or non-ferrous metal part and instrument under fixing and condition of external field with electroslag permanent casting legal system, make the mechanical performance of foundry goods reach the level of forging, the foundry goods shape is very near the shape of fabricated part simultaneously.
In known a kind of special-shaped casts casting (SU, A, 548149), motlten metal is poured in the die with the mode of slag used in Metal Melting with open flow.This method can not guarantee the continuity of electroslag remelting metal flow when the metal of electroslag remelting is poured into a mould in die by hopper, because metal contacts with atmosphere when pouring into a mould in the mode of open flow, make in the metal metal inclusion state that reaches capacity, so that reduced the quality of foundry goods.
Known another kind of special-shaped casts casting (SU, A, 3333625) according to said method obtains motlten metal and slag in hopper, then it is poured in the die.Hopper and die are rigidly connected mutually, make the die wall be actually the continuity of bucket wall, and motlten metal and slag promptly flow along the die wall, and the upper end face of die and hopper is separated from each other.Therefore, die and hopper form the untight integral body of one side, realize the cast of metal and slag by the method for this integral body being watered the trunnion axis upset.
But the feasibility of this technology is restricted.This be because, if motlten metal and slag are spilt by watering overturn the fast method casting metal and the slag of misclosure integral body of trunnion axis; If overturn misclosure integral body at a slow speed, then considerable slag can condense on the wall that connects die and hopper, thereby the die foundry goods has serious blemish.In addition, in this misclosure integral body of forming by die and hopper, can't heat the notch portion of emitting of foundry goods effectively, can in foundry goods, produce shrinkage cavity and other casting flaw like this, otherwise just have to use a large amount of flux for fear of these defectives.
Known another kind of electroslag refining furnace (SU, A, 606359), it comprises pillar, the bracket of electrode is housed, be contained on the swinging mounting hopper, support arm and bottom bracket in order to holding molten metal and slag.Hopper shell is connected with bracket by mechanism with flexible elements, and adopts the die of placing separately in order to produce special-shaped casts.Hopper overturns around rotating support after obtaining motlten metal and slag, thereby makes liquid metals and slag inject die.
Known another diecasting device (SU, A, 656350) is to be made up of the hopper and the electrode feed mechanism of motlten metal and slag.Hopper is for describing device, and it pushes up down that ， And can utilize independent transmission mechanism around self axis rotation.Hopper and transmission mechanism are contained on the platform, and this platform can rotate in vertical plane by independent transmission mechanism.Hopper overturns in vertical plane with platform after slag obtaining the deposite metal, thus can be in the die of independent placement casting metal and slag.
Existing these devices can not guarantee the continuity of electroslag remelting metal flow, because metal is the die that injects independent placement in the mode of open flow.
Known a kind of special-shaped casts casting device, it comprises the hopper and the die of motlten metal and slag, hopper has and can make the own transmission mechanism that rotates with respect to horizontally hinged fulcrum in vertical plane, die all is rigidly fixed to (B.E.Paton on the hopper in the overall process of gathering and cast electroslag remelting metal, B.I.Medovar, U.V.Orlovski work " electroslag casting " (Russian) nineteen eighty-two, Ukraine Intellectual Press (Kiev) the 51st～53 page).
Owing to be fixed on the continuity that hopper cast end that hopper puts is actually the die wall outward, the disruption that the electroslag remelting metal flow therefore when the electroslag remelting metal is poured into a mould in die by hopper, can not occur, and metal always is in below the molten slag layer, thereby can prevent that metal from contacting with atmosphere, guarantee the high-quality of foundry goods.
But the productivity ratio of this device is low, because at casting solidification with will pour into a mould die and change that hopper is inverted in time of sky die into, so a motlten metal under can not splendid attire.
For make foundry goods particularly heavy castings solidify, the time of being lost may reach holding molten metal and pouring into a mould 50% of required effective time.
The objective of the invention is to change the order of special-shaped casts diecasting operation and arrange the relative position of die and motlten metal and slag hopper in the casting device properly, so that in die, can prevent that metal from overflowing together with slag when casting molten metal and slag, And and can also before replacing the die of having poured into a mould, in hopper, send into a motlten metal and slag down with new die.
The method of finishing the object of the invention is, in special-shaped casts diecasting method, earlier motlten metal and slag are contained in the material bin, be poured in the die then, remain to crystallization and obtain special-shaped finished product cast, according to the present invention, the cast before die place hopper above, their upper end face is fitted mutually.In order to realize the cast of motlten metal and slag, overturn simultaneously die and hopper are in till the position of hopper below until die, thus with motlten metal and slag by the hopper metaideophone to die.Motlten metal and slag by the hopper metaideophone to the process of die, their joint of upper end face in the metaideophone district should be obturaged.
Die and hopper upper end face be the joint in die metaideophone district at motlten metal and slag, the most handy method that temporarily stops pouring into a mould till when this molten slag layer is solidified during from the topped joint of living in the metaideophone district of the molten slag layer joint of obturaging.
This time-out duration of pouring of motlten metal and slag, preferably elect 2% of cast total duration at least as.
The molten slag layer of topped die and hopper upper end face joint is preferably forced cooling.
Hopper preferably remains to the complete crystallization of foundry goods above die.
The method that solves the task of putting forward also is, hopper is equipped with the transmission mechanism that can overturn in vertical plane in comprising the special-shaped casts diecasting equipment of motlten metal and slag hopper and die, according to the present invention, the installation of die should make die move to hopper their upper end face is fitted mutually, whole to cause die and hopper to form a sealing, this seals whole available hopper transmission mechanism and rotates in vertical plane.
Die and motlten metal and slag hopper preferably are fixed on the common pivoting support, and the upset of die in vertical plane preferably has independent transmission mechanism.
In another kind of structural shape, motlten metal and slag hopper preferably are hingedly fixed in two bearing Zhi Jian And can occupy two positions, a position elevating hopper is connected with a bearing therein, on another position, be connected with another bearing, an additional die at least also will be arranged simultaneously, this additional die is fixed on independent pivoting support Shang And and has the transmission mechanism that overturns in vertical plane, it can form a sealing integral body with hopper on the position in two positions, and the whole transmission mechanism that replenishes die that can utilize of this sealing overturns in vertical plane.
