Abstract
The invention relates to a method to produce aluminum-boron alloy by using aluminum cell. It adopts alumina, boric anhydride as raw material and the device is aluminum cell. The method includes the following steps: directly adding alumina and boric anhydride into aluminum cell to melt in cryolite melt, under the effect of DC current, the cathode of aluminum cell would separate out metal aluminum and metal boron, under the whisking of magnetic force from electrolyte tank, the aluminum-boron alloy would be formed. The advantages of the invention is that it need not device invest, and the raw material is easily to get, the energy consumption and producing cost is low, the quality of aluminum-boron alloy is high, and there is no segregation.
Description
Technical field: the present invention relates to a kind of method of producing aluminum-boron alloy with aluminium cell, belong to the aluminium reduction process field of production, is a kind of method with sodium aluminum fluoride one aluminum oxide, boron oxide aluminum production by fused-salt electrolysis boron alloy specifically.
Technical background: the production of aluminum-boron alloy industrial be to adopt molten method of completing the square always, promptly be will metallic aluminium and the fusing of metal boron after be in the same place to mixing in proportion, cast aluminum-boron alloy then.This method energy consumption is big, the cost height, and the casting yield of boron is low, and it is lower to utilize the present invention to produce the energy consumption and the cost of aluminum-boron alloy, and the casting yield of boron reaches about 98%, and the aluminum-boron alloy of producing is of high quality, and its chemical ingredients is even, segregation-free.
Summary of the invention: the purpose of this invention is to provide a kind of employing direct current by electrolyzer negative and positive the two poles of the earth, with the method for sodium aluminum fluoride-aluminum oxide, boron oxide aluminum production by fused-salt electrolysis boron alloy.
The objective of the invention is to realize by following technical scheme:
(1) in aluminium cell, makes anode, wherein: electrolyte level: 16 with ice crystal masonry ionogen, aluminium liquid
~22cm, aluminum liquid horizontal: 18
~24cm;
(2) serve as the raw material of producing aluminum-boron alloy with aluminum oxide and boron oxide, the purity of aluminum oxide is not less than 98.4%, and the purity of boron oxide is not less than 98%;
(3) directly add aluminum oxide and boron oxide in selected aluminium cell, they are dissolved in the middle of the cryolite melts, the fusion concentration of boron oxide in ionogen is 0.5%-0.9%;
(4) under galvanic effect, beginning precipitating metal aluminium and metal boron on the negative electrode of aluminium cell;
(5) under the stirring of the magnetic field force that electrolyzer produces, form the uniform aluminum-boron alloy of chemical ingredients;
(6) use suction aluminium bag with the aluminum-boron alloy sucking-off, and cast the aluminum-boron alloy ingot.
Advantage of the present invention is: produce aluminum-boron alloy with the aluminium cell of producing aluminium, need not the equipment input, and processing condition are with to produce electrolytic aluminum identical, and ordinary student produces the electrolgtic aluminium aluminum oxide and makes raw materials for production, and the production aluminum-boron alloy, just increased boron oxide on the basis that produces electrolytic aluminum and made raw materials for production, be very easy to grasp, energy consumption and the cost of producing aluminum-boron alloy are lower, the casting yield of boron reaches about 98%, and the aluminum-boron alloy of producing is of high quality, and its chemical ingredients is even, segregation-free.
