The invention particularly relates to a preparation method of a cold-pressed ball for a converter and the cold-pressed ball for the converter, and belongs to the technical field of iron-containing solid waste recycling. The preparation method of the cold-pressed ball for the converter comprises the step of obtaining the steel slag. The steel slag is crushed and screened to obtain pre-selected steel slag and circulating steel slag. And carrying out ball milling and water washing on the pre-selected steel slag, and then carrying out magnetic separation to obtain fine iron powder and iron beans. Mixing and stirring the fine iron powder, the iron beans, a binder and water, and performing compression molding to obtain a ball blank; and drying the ball blank to obtain the cold-pressed ball for the converter. According to the preparation method, the cost in the preparation process of the cold-pressed balls and the iron content of the cold-pressed balls can be considered, the prepared cold-pressed balls for the conve
