The invention provides a method for preparing a baking-free brick by mixing slag micro powder and glue. The method comprises the steps of raw material crushing; sieving, wherein crushed raw materials are put into screening and stirring equipment, and raw material particles in accordance with the size are obtained through vibration screening; stirring, wherein the obtained raw material particles and other raw materials are stirred in the screening and stirring equipment, and raw material slurry is obtained after sufficient melting; injection molding; mold pressing; and steam curing, wherein an obtained brick blank is fed into an autoclave to be subjected to autoclaving, a silicate product is subjected to a hydration reaction, finally a finished product is obtained, and operation is completed. Through the method, by adding a small amount of cement, the strength of a brick body is guaranteed, the particle size of the raw materials is controlled through a vibration screening mechanism, and the situation that due
