Desulfurization gypsum mold box and preparation method thereof

The invention discloses a desulfurization gypsum mold box and a preparation method thereof. The desulfurization gypsum mold box comprises desulfurization gypsum Beta powder, pulverized fuel ash and steel slag according to a certain ratio. The preparation method comprises the following steps: A, preparing raw materials: desulfurization gypsum is calcined into desulfurization gypsum Beta powder through a secondary heat-seeking one-step method; B, mixing the desulfurization gypsum Beta powder, the pulverized fuel ash and the steel slag according to the certain ratio, stirring after adding water, pressing by a full-automatic gypsum mold box molding machine, and demolding; and C, stacking in a drying yard and naturally drying for 7 to 10 days to obtain the desulfurization gypsum mold box. The method is easy to implement, and the operation is simple and convenient. The automatic feeding, the stirring, the press molding and the mechanical demolding can be achieved, so that the desulfurization gypsum mold box achieve
