The invention relates to a chrome-silicon content control method of a chrome-containing steel ball. The method comprises the following steps: by taking chromium iron and waste steel uniform in component as raw materials, in the chromium iron, measuring the percentage of chrome as m1 and that of silicon as n1; in the waste steel, measuring the percentage of chrome as m2 and that of silicon as n2; and calculating the weight A of chromium iron and the weight B of waste steel according to formulae (1) and (2), wherein m is the designed percentage of chrome in the chrome-containing steel ball and n is the designed percentage of silicon. According to the method provided by the invention, before production and operation, the weights of the raw materials chrome iron and waste steel are calculated according to the formulae in light of the contents of chrome and silicon in the high chrome steel ball, and finally, the contents of chrome and silicon in the high chrome steel ball are obtained to meet the design requirements. Compared with the prior art, silicon iron needs not to be added in the production and operation process to adjust the content of silicon, so that precise control of the contents of chrome and silicon in the high chrome steel ball are realized. Furthermore, the operating step is simplified, and the operating risk is reduced.
