Titanium clad copper bar is the main component of metal anode. It integrates the excellent electrical conductivity of copper and the excellent corrosion resistance of titanium, and successfully replaces the graphite anode, increasing its life by more than 10 times and saving energy by more than 20%. , and improve the purity of caustic soda, is an excellent electrode material. Recently, copper composite rods have been used in the electrolytic copper industry as conductive rods. After use, the electrical conductivity and current efficiency are improved, and the power consumption is reduced. At the same time, the service life of the electrode is improved, and the maintenance cost is reduced.
Titanium-copper composite rods have developed rapidly since their introduction in the 1960s. The first was jointly developed by the Italian Derona Company and American Bauxite Company in 1968. Since the 1970s, many countries in the world, such as Japan, the United States, West Germany, France, and Italy, have successively adopted titanium anodes instead of graphite anodes and put them into industrial production. my country started the research and development of titanium-copper composite rods in 1973.
There are many production methods for titanium clad copper rods, and methods such as the explosion composite method or titanium tube-sleeve copper rod are mainly used abroad. At first in China, copper rods were inserted into titanium tubes and then connected with lead to make conductive rods. This kind of composite rod is not easy to make, and secondly, the conductivity is unstable, which causes the tank pressure to rise. Later, some people used the method of titanium tube sleeve copper rod + stretching to produce composite rods. At present, the main manufacturers of titanium-copper composite bars use the extrusion method. The production method of extruded ingots starts to use large-diameter thick-walled titanium tube blanks, which are filled with round copper rods and sealed with titanium plates at both ends. Due to the gas in the gap between the copper ingot and the titanium tube, the composite quality of the composite rod will be affected at high temperatures. The titanium composite copper rod produced by the extrusion method, because it is a hot processed product, was found to have poor bending resistance and poor surface roughness during actual use. Later, the extruded rod was subjected to appropriate cold stretching, on the one hand, the bending resistance of the bar is improved, and on the other hand, the surface roughness of the bar is improved. After years of use by users, the feedback is good. In the late 1980s, the explosion method was also used to produce titanium-copper composite rods, but the production capacity was not formed due to low efficiency and high cost. In recent years, some people have used the explosion + rolling method to produce composite rods, and they have also achieved success.
