Abstract
A method for producing a nickel plate blank comprises the following steps: A) using electrolytic nickel to prepare a columnar nickel electrode; B) placing the columnar nickel electrode in a vacuum consumable skull furnace chamber; C) fixing a die for casting the nickel plate blank on a die body support which is located in the furnace chamber and can rotate in high speed, to ensure that the casting gate corresponds to the liquid outlet of a crucible which is arranged in the furnace chamber and is used to hold liquid; D) sealing the furnace chamber to ensure that the inner vacuum degree of the furnace chamber is no less than 0.3pa; switching on a power supply, moving the other electrode to approach the columnar nickel electrode, generate an arc between the two electrodes and ensure that the nickel electrode is melted to be liquid and deposited in the crucible, wherein the smelting current beween the two electrodes is 20+/-6KA and the smelting voltage is 40+/-6V; E) using the die body support to drive the die to perform high-speed rotation, injecting the liquid of the crucible in the die chamber to perform centrifugal casting; and F) naturally cooling the casted nickel plate blank along with the die to realize consolidation forming.
Description
Technical field
The present invention relates to utilize the method for vacuum consumable casting nickel slab, especially belong to nonferrous materials and manufacture the field.
Background technology
Nickel is one of important strategic metal in the heavy non-ferrous metal, and nickel is silvery white metal.Characteristics such as that nickel has is anti-corrosion, heat-resisting, intensity is high, plasticity is good have been widely used in steel-making, have electroplated, industrial sectors such as system alkali, electrovacuum, oil, chemical industry.Abroad, the melting and the processing history of nickel are longer, and description is complete, its processing material mature production technology, advanced technology.Nickel material major country of production has: Canada, the FSU, Japan, Norway, Britain, Cuba etc., China's nickel output accounts for the 7th in the world at present.The production of China nickel processing material is started in the sixties, compares with advanced international standard, and there is a big difference for tool, has only factory of several family can produce nickel processing material at present, no matter kind, specification, quantity and still not exclusively satisfy market demand qualitatively.
The traditional technology of-milled sheet that the production of nickel plate is mainly followed: ingot casting--forging slab--.Must be through twice above melting.Finished ingot is forged into slab again through after the peeling, and is rolling after the peeling once more, and twice peeling wherein arranged, and it is about 12～15% that loss amounts to, and greatly reduces lumber recovery.Improve lumber recovery, will reduce the peeling amount in the course of processing, improve the lumber recovery of slab.How reducing the peeling amount is the key that improves lumber recovery.
Summary of the invention
The present invention seeks to propose a kind of method of producing the nickel slab, especially a kind of with short production cycle, low cost of manufacture, the method for the production nickel slab that utilization rate of raw materials is high.
A kind of method of producing the nickel slab is made up of following process: A, process the bar shape nickel electrode with electrolytic nickel; B, the bar shape nickel electrode is inserted in the vacuum consumable scull furnace chamber; C, the mould that will cast the nickel slab be fixedly installed on be positioned at furnace chamber and can the die body bearing of high speed rotating on, and make the pouring gate on the die body bearing top Sheng liquid interior corresponding with the liquid flowing outlet of crucible with being arranged on this furnace chamber; D, sealing furnace chamber, and make the interior vacuum tightness of furnace chamber be not less than 0.3pa; Energized moves another electrode, make the column nickel electrode near and make and keep the starting the arc between the two, the melting electric current reaches 20 ± 6KA between the two, melting voltage reaches 40 ± 6V, makes nickel electrode be fused into liquid and amasss in crucible; E, make the die body bearing drive the mold high speed rotation, simultaneously the liquid in the crucible is injected rotational casting in this mold cavity, the rotational casting process was accomplished in no more than 5 seconds; F, the nickel slab after will casting make it coagulation forming with the mould naturally cooling.Said mold cavity is tabular mold cavity, and volume can receive certain limitation certainly.
Compared with present technology have after the present invention realizes with short production cycle, low cost of manufacture, utilization rate of raw materials advantages of higher.The present invention need not forge into slab (having bigger loss) later on through peeling again with ingot casting.The present invention can guarantee the even of slab tissue, good quality through the rapid shaping casting.
Embodiment
The method of production nickel slab of the present invention is made up of following process: A, process the bar shape object with electrolytic nickel, make it to form nickel electrode; Especially electrolytic nickel is pushed or is welded into bar shape nickel electrode, i.e. vacuum consumable electrode; B, nickel electrode is inserted in the vacuum consumable scull furnace chamber, and be fixedly connected and be positioned on the electrode dop of this furnace chamber, make it to form the extreme of an electrode, nickel electrode is carried out melting; C, the mould that will cast said nickel slab be fixedly installed on be positioned at furnace chamber and can the die body bearing of high speed rotating on, and make its pouring gate Sheng liquid interior corresponding with the liquid flowing outlet of crucible with being arranged on this furnace chamber; D, sealing furnace chamber, and make that vacuum tightness is not less than 0.3pa in the furnace chamber, energized afterwards; Move another electrode dop, make nickel electrode continuously near relative with it, and constitute the extreme crucible of another electrode; Make and keep the starting the arc between the two; And make between the two that the melting electric current reaches 22KA, melting voltage reaches 40V, make nickel electrode be fused into liquid, and amass in crucible.E, make the die body bearing drive the mold high speed rotation; Simultaneously the liquid in the crucible is injected in this mold cavity; Being about to the nickel electrode liquation casts in the nickel slab casting mold cavity that is positioned at furnace chamber and high speed rotating (rotating speed is not less than PM 300 commentaries on classics; Rotating speed especially PM 300-500 changes), and this rotational casting process was accomplished in the time in no more than 5 seconds.F, the nickel slab after will casting make it coagulation forming with the mould naturally cooling.Foundry goods is taken out in G, die sinking, promptly gets nickel slab finished product.Mold cavity of the present invention is tabular mold cavity, and moulding is tabular, and to be prepared into composition even for the electrolysis ingot casting like this, the tabular nickel that proterties is good.
