本发明是属于冶金、铸造领域里的一项技术问题，主要解决的问题是用一带有微处理机程序控制的结晶器进行铝的提纯。这种结晶器适合于我国铝资源的状况，其凝固速度可用微机控制在５～１０mm／min范围内，解决了日本专利中的结晶器不适合我国铝提纯这一技术问题，本发明如果应用
The invention belongs to a technical problem in the field of metallurgy and foundry, and the main problem to be solved is that the aluminum is purified by a mold controlled by a microprocessor program. This mold is suitable for the status of aluminum resources in our country, and its solidification speed can be controlled by microcomputer in the range of 5 ~ 10mm / min, which solves the technical problem that the crystallizer in Japanese patent is not suitable for aluminum purification in our country. If the invention is applied
