Abstract
The invention relates to a method for removing iron contained in a silicon-aluminum alloy. The method is characterized by comprising the following steps of: firstly carrying out melting dehydration on manganese chloride, and then carrying out cooling crystallization; then selecting the dehydrated and crystallized manganese chloride according to the weight ratio of 1.8-2 times of the ion content of a smelted silicon-aluminum alloy, placing into a closed bell jar, pressing into silicon-aluminum alloy melting liquid during smelting, slowly stirring, and heating till no bubble is formed. The treated silicon-aluminum alloy is obviously improved in property, enhanced in tensile strength by 5%-15%, enhanced in elongation percentage by more than 10% and convenient to operate.
