Technical Field
The invention belongs to the technical field of electroslag metallurgy, and particularly relates to a metal wire feeding device, a feeding system and a feeding method.
Background
Electroslag remelting is a process of re-refining steel (usually electric furnace steel or converter steel) produced by a general smelting method. In the remelting process, active elements in steel, such as Al, Ti, Ce, B and the like, are lost due to oxidation. How to prevent the oxidation of active elements is one of the important metallurgical problems of electroslag remelting. Electric powerOxygen typically enters the slag and liquid steel during slag remelting through the following routes: (1) oxygen dissolved in original electrode steel and unstable oxides in the steel are decomposed at high temperature to release oxygen; (2) oxygen carried into slag by oxide skin on the surface of the electrode; (3) unstable oxides FeO, MnO and SiO in slag2、Cr2O3Etc. oxygen contained therein; (4) the valence oxides in the slag transmit oxygen supply action, such as low valence oxides of Fe, Ti, Mn, Cr and the like in the slag, and absorb oxygen in the atmosphere on the surface of a slag pool to form high valence oxides. The higher oxides of these elements, at the slag bath and metal bath interface, evolve oxygen, becoming lower oxides, which then enter the steel.
In order to reduce oxygen in the electroslag ingot, reduce element burning loss and improve the quality of products required by smelting. The modern metallurgical process generally adopts vacuum arc remelting, vacuum induction remelting, electron beam melting and electroslag remelting processes, inert gas is introduced for protection, and a deoxidizer and the like are added. The several methods are specific, vacuum arc remelting, vacuum induction remelting and electron beam melting can obtain high-quality steel ingots with low gas content, high purity, uniform and compact structure and small component segregation, and the alloy is ensured to have excellent process plasticity and high mechanical property. However, the equipment is complex, the maintenance cost is high, the alloy production cost is high, and the problems of poor alloy reproducibility and the like can occur. In comparison, the direct addition of a deoxidizer in the electroslag remelting process is a preferred choice, the deoxidizers are various, aluminum is used as a strong deoxidizing element, and most of the electroslag remelting processes adopt aluminum or aluminum-containing composite deoxidizers for deoxidation, so that the method has the advantages of simple acquisition process, low price and the like.
Through search, chinese patent 201610946313.5 discloses a method for adding aluminum powder during electroslag remelting, wherein aluminum powder with different particle sizes is uniformly placed on a conveyer at certain intervals, and is uniformly and continuously added into a crystallizer through the conveyer. The method comprises the following specific steps: (1) suspending a conveying device for placing aluminum powder on a smelting support arm of the electroslag furnace by a weight; (2) uniformly laying aluminum powder with the particle size of 1-3 mm on a conveying device; (3) placing aluminum powder with the particle size of 8-10 mm on a conveying device at a distance of 10-12 cm from each other; (4) the aluminum powder is added into the crystallizer by the movement of the conveying device. Through aluminium powder adding device, the aluminium powder that is 1mm ~ 3mm with the granularity conveys into the sediment pond, makes the oxygen in the sediment pond effectively reduce, prevents that oxygen from spreading into the molten bath: when aluminum particles with larger granularity of 8 mm-10 mm fall into the crystallizer, the aluminum particles with larger granularity can enter into the molten pool, thereby effectively removing oxygen in the molten pool and achieving the purpose of improving the metallurgical quality and performance of the steel ingot. But has the disadvantages that: this process of adding aluminium probably needs different modes of addition to the aluminium grain of different particle diameters, and the precision that relies on this conveyer to add aluminium is lower moreover, and the aluminium grain addition is difficult to accurate control, can only rely on the manual work to judge the quantity of aluminium powder whether reach required content, and the in-process aluminium powder that adds aluminium powder in addition can burn and lose, has reduced the rate of recovery of aluminium.
