China is rich in diaspore with high silicon,high titanium and low iron,which,is hard to be processed to produce alumina.A
new process for direct producing
Al-Si-Ti alloy in large aluminum reduction cells by adding silicon,titanium and alumina can shorten process flow,reduce investment,energy consumption and cost.The results of the
experiment in 140 kA cells indicate that during experiment the average current efficiency of the cells is 90 2%.This experiment provides a new way to produce high quality alloy material.The bauxite can be comprehensively utilized and remarkable economic and social benefits can be obtained. As an intermediate alloy.the Al-Si-Ti alloy can be used to produce every kinds of Ti-containing cast alloy which is widely used in auto industry,piston of internal combustion engine,machinery building,high voltage electrical appliance,etc.Comparing with traditional alloy producing by melting/proportioning method,the intensity,thermal stability and wear resisting property of this kind alloy are much better.
