Description
Affiliated technical field
The present invention relates to the specific equipment of hot metal vacuum melting
Background technology
Metallic substance is the basic substance that the mankind depend on for existence and development, and is more and more higher to the requirement of metallic substance at various technical fields high-technology field particularly, causes the application of vacuum melting more and more wider.Developed country extensively adopts vacuum melting technology to produce various steel and non-ferrous metal alloy at present.
Vacuum melting is the method that high melt is purified metals under vacuum.Vacuum smelting method commonly used has: vacuum induction melting, vaccum consumable electrode electric arc furnace melting, electron beam melting etc.Various melting method are to molten alloy Effect on Performance difference.In general, vacuum self-consumption electrode arc melting can improve alloy plasticity at high temperature; Can improve the processing performance of the thermal pressure processing of alloy; Quality and homogeneity to finished product play desirable influence.Vacuum self-consumption electrode arc melting has become one of main method of high duty alloy melting with vacuum induction melting.The principle of vacuum consumable electrode electric arc remelting is under vacuum environment, and the electrode of metal is rapidly fusing and carry out resolidification in water mold under the high temperature action of electric arc.When the form of liquid metal with molten drop shifts to crystallizer from the pyritous arc zone, in crystallizer, keep and solidify, the series of physical chemical reaction takes place, impel molten metal to obtain refining, purification.The essence of vacuum consumable electrode electric arc remelting simply says that exactly the heat energy by means of electric arc carries out remelting and moulding in water mold to the metal consumable electrode of known chemical composition under vacuum state, to improve the fusion process of its quality.
The industrial conventional vaccum consumable electrode electric arc furnace basic structure of using as shown in Figure 1.
Self-consuming furnace is formed an airtight melting space by body of heater (4) and copper crucible (11).For the lifting of consumable electrode (7), one set of lifting mechanism and tightness system are arranged at stove top.There is vacuum slipper seal (3) in furnace roof portion, and this sealing can guarantee that elevating lever (2) does not destroy the vacuum tightness in the stove when entering in the stove outward by stove.The outside end of elevating lever connects press power cathode (16), the other end installation chuck (5), and the stove outside has electrode feed mechanism (1) can drive elevating lever to move up and down.
Elevating lever chuck clamping one transition electrode (6), transition electrode are the transition apparatus between electrode and chuck, guarantee the current delivery of electrode negative potential.Electric arc connects between the lower end of consumable electrode and the copper crucible (11).Vacuum static seal (9) is arranged between copper crucible and body of heater, and copper crucible one end is equipped with positive pole (15) coupling device.The copper crucible is surrounded by water jacket (12) outward, and water coolant advances from water-in (14), and water outlet (10) goes out.Form the cooling loop of ingot casting (13).Body of heater and crucible constitute an enclosed space by vacuum slipper seal and vacuum static seal, link to each other with the outer vacuum system of stove by vacuum adapter (8), can make the vacuum tightness in the stove be evacuated to certain value by processing requirement during work.
Do not adopt the copper crucible yet but adopt under the ingot casting and draw mechanism, as shown in Figure 2.Water mold (20) bottom is a movable mechanism of drawing down, and the ingot casting of cooling forming (13) is descending gradually under the traction of ingot-guiding head (17) in crystallizer, and ingot casting length is looked the length of piston rod (18) and oil cylinder (19) and decided.
The technological process of simple description consumable electrode arc furnace is as follows.Treat that the metal of remelting makes electrode earlier, firmly weld with transition electrode, the chuck of elevating lever clamps transition electrode, consumable electrode is loaded onto the copper crucible after putting in the stove, and self-consuming furnace is airtight, is evacuated to definite value, general who has surrendered's consumable electrode is delivered to nearly crucible bottom under the elevating lever, be placed with heelpiece and starting the arc agent on the crucible bottom or only put starting the arc agent, under open circuit voltage, produce arc discharge and then reach stable arc burning, form a certain amount of metal pool by means of contacting when dim between consumable electrode and the starting the arc agent.Change normal smelting over to after the starting the arc success.Reasonable control current, voltage, melting speed and vacuum tightness during normal smelting, the gas in the metal and low-melting impurity can be removed.
In vacuum consumable electrode electric arc remelting processing, the diameter of consumable electrode and crucible diameter should have a rational proportion, and electrode diameter too big (near the crucible diameter) influences exhaust, and the limit arc burns out crucible wall easily, the too little thermosteresis that then can make is excessive, and bath temperature is inhomogeneous.
In order to improve the quality of cast metals, have and adopt secondary remelting and even three remeltings.
The vaccum consumable electrode electric arc furnace that uses has multiple structure both at home and abroad, but its principle is mostly identical, and difference only is the layout difference of feed mechanism, taking-up ingot casting mechanism and the vacuum system of size, electrode.
The weight of electric arc furnace finished ingot depends on the weight of consumable electrode, industrial production is in order there to be rational yield rate, hope can have big as far as possible ingot casting, this just needs very long consumable electrode, the height of self-consuming furnace furnace body is greater than the length of consumable electrode, stove also will have longer operating mechanism outward, thus in industry spot in order to pursue the large-tonnage finished ingot, self-consuming furnace is designed to very high body of heater as much as possible.
In order to obtain heavy weight ingot casting, the consumable electrode diameter also must be thick (otherwise electrode length exceeds the open ended height of furnace body), the crucible diameter is corresponding just bigger, large diameter ingot casting is unfavorable for crystallisation by cooling, for the processing of road, back, large diameter ingot casting has also increased the forged difficulty of cogging, but the length of electrode and diameter have determined the length of finished ingot and the diameter of crucible, and the big thick and forged difficulty of ingot casting crystalline can only be transferred to next procedure and go to solve.
So the technology of long ingot casting is rarely found in vacuum consumable electrode electric arc remelting processing preferably than fine crystallization to cast diameter with the mode of dummy ingot under the crystallizer.
