扼要介绍铝硅系合金的熔配法、电热还原法和电解法三种不同生产工艺。电解法适合我国铝矿资源特点，产品质量优越，值得在国内推广；电热还原法具有单台设备产能大，可以利用季节性电源等优点，在条件适宜的地区可以相应发展；熔配法则工艺复杂，流程长，能耗高，成本贵，除特殊地区和特殊情况外，应逐渐减少使用． Brief introduction of aluminum-silicon alloy melting method, electrothermal reduction and electrolysis of three different production processes. Electrolysis is suitable for the characteristics of China’s aluminum resources, product quality is superior, it is worth to be promoted in the country; Electrothermal reduction method has the advantages of large capacity of a single device, you can use seasonal power, the appropriate conditions in the region can be a corresponding development; , Long process, high energy consumption, high cost, in addition to special areas and special circumstances, should gradually reduce the use of.
