Abstract

A process for preparing Al-Ti alloy by direct electrolysis of carbon anode containing titanium oxide includes such steps as mixing calcined petroleum coke (73-81 wt.%), coal asphalt (17-25) and titanium oxide powder (0.5-5), heating while kneading for 30-45 min, shaping anode, calcining, installing said anode to electrolyzer, and electrolyzing. Its advantages are high performance of product, low cost, high uniformity and high current efficiency.

Description

With the method that contains the direct electrolysis production aluminum titanium alloy of titanium oxide carbon anode
(1) technical field: the present invention relates to a kind of electrolytic process direct production aluminum base alloy technology of using, particularly a kind of usefulness contains the method for the direct electrolysis production aluminum titanium alloy of titanium oxide carbon anode.
(2) background technology: the production technology of aluminum current titanium alloy mainly contains two kinds, and first kind is with fine aluminium, the molten aluminium titanium master alloy that is made into of pure titanium; Second kind is to adopt the thermite reduction mix-melting method to produce aluminium titanium master alloy with fine aluminium, titanium salt, titanium oxide; The third is directly to add titanium oxide in aluminium cell, produces aluminium titanium master alloy.Titanium content in the aluminium titanium master alloy of producing with above three kinds of methods is generally 1-5% (weight percent), if when manufacturer needs use aluminum titanium alloy, also needs fine aluminium and aluminium titanium master alloy melted once more and is made into desired aluminum titanium alloy.More than three kinds of production technique all exist long flow path (needing repeatedly molten joining), metal loss is big, molten timing energy consumption height, the shortcoming that production cost is high.The third method is that titanium oxide is added aluminium cell, direct electrolysis production aluminum titanium alloy, and this technology causes very big difficulty to the ordinary production management of aluminium cell, and titanium segregation in aluminium liquid is serious, and current efficiency is low.
(3) summary of the invention: a kind of usefulness that the objective of the invention is to develop at the problem of above existence contains the method for the direct electrolysis production aluminum titanium alloy of titanium oxide carbon anode, and its purpose one is to produce the carbon anode that contains titanium oxide.Prepare burden by weight percentage earlier, its proportioning is: after-smithing petroleum coke 73-81%, coal-tar pitch 17-25%, titanium oxide powder 0.5-5%; Batching is placed on can heat mixed pinches to mix to pinch in the pot and was made as thickener in 30-45 minute; What thickener is processed into required specification contains the titanium oxide carbon anode again, and the processing condition of producing carbon anode according to routine are carried out roasting then, and roasting becomes to contain the carbon anode of titanium oxide.Its purpose two is that the titanium oxide carbon anode that contains that roasting is good is installed on the aluminium cell, directly carries out the electrolysis production aluminum titanium alloy.Produce aluminum titanium alloy with aforesaid method, it is simple to have method, and flow process is short, the characteristics that production cost is low.It can utilize the titanium oxide powder that cheaply is easy to get to substitute expensive metal titanium; It neither needs repeatedly molten joining, and has overcome the alloy segregation of production aluminium titanium master alloy and the difficult problem of uneven components again.This method with titanium oxide is added in the electrolyzer directly to the method for electrolytic aluminum titanium master alloy and compares, solved in the production process titanium oxide and flown upward that loss is big, current efficiency is low, the unmanageable technical barrier of aluminium cell.The performance of the aluminum titanium alloy of producing with this method obviously is better than the aluminum titanium alloy produced with mix-melting method.
(4) embodiment: the present invention is described in further detail below in conjunction with embodiment.
Embodiment 1:
The first step.Production contains the carbon anode of titanium oxide: prepare burden by weight percentage earlier, proportioning is: after-smithing petroleum coke 81%, coal-tar pitch 17%, titanium oxide powder 2% take by weighing after-smithing petroleum coke 2.49Kg, coal-tar pitch 0.51Kg, titanium oxide powder 0.06Kg; The batching of 3.06Kg is placed on can heat mixed pinches to mix in the pot and pinched 30 minutes, make the 3.06Kg thickener, again the thickener of 3.06Kg made 3 diameters and be 60mm, highly contain titanium oxide right cylinder green anode piece for 150mm, pack into then and carry out roasting in the stoving oven, the top temperature of roasting is 1200 ℃, be incubated 4 hours, be cooled to room temperature, can make and contain the titanium oxide carbon anode.Below add 2% titanium oxide powder and do not add the physical and chemical index of the carbon anode that the oxidation titanium valve makes with table 1 explanation.Table 1:
Figure A0113837000041
Second step was carried out direct electrolysis production aluminum titanium alloy with the good titanium oxide carbon anode that contains of roasting.Use titanium oxide content be 2% contain the titanium oxide carbon anode, to contain the titanium oxide carbon anode is installed on the small aluminium electrolytic cell, the control electrolysis temperature is 950 ℃, bath voltage is 4.1 volts, pole span is 4.1 centimetres, alumina content is 3.7% in the sodium aluminum fluoride, can make titanium content and be 0.24% aluminum titanium alloy.

Claims (1)

1, a kind of usefulness contains the method for the direct electrolysis production aluminum titanium alloy of titanium oxide carbon anode, it is characterized in that: produce the carbon anode that contains titanium oxide earlier, prepare burden after-smithing petroleum coke 73-81%, coal-tar pitch 17-25%, titanium oxide powder 0.5-5% by weight percentage; Batching is placed on can heat mixed pinches to mix in the pot and pinched 30-45 minute, be made as thickener; What thickener is processed into required specification contains the titanium oxide carbon anode again; Produce the processing condition of carbon anode then routinely and carry out roasting, roasting becomes to contain the titanium oxide carbon anode; Second step was that the titanium oxide carbon anode that contains that roasting is good is installed on the aluminium cell, and direct electrolysis method is produced aluminum titanium alloy.
