The utility model relates to the technical field of steel billet processing, and discloses a heat preservation forging device for steel billet processing, which comprises a forging furnace, the outer wall of the forging furnace is fixedly connected with the inner wall of a furnace door, the outer wall of the furnace door is fixedly connected with the inner wall of a discharging frame, and the forging furnace is provided with a heat preservation mechanism for carrying out heat preservation treatment on steel billets. The heat preservation forging device comprises a heat preservation mechanism, a protection mechanism is arranged on the heat preservation mechanism, the heat preservation mechanism comprises heat transfer pipes, the tops of the heat transfer pipes are fixedly connected with the inner wall of a forging furnace, the heat preservation mechanism is arranged, and the two heat transfer pipes are connected to the bottom of the forging furnace and used for collecting heat in the forging furnace. And an activated carbon filter screen and a control shaft are arranged in the heat dissipation pipe, the angle of the heat insulation plate is controlled by rotating a rotary knob at one end of the control shaft, the heat in the heat storage pipe can be discharged out of the heat dissipation pipe, and therefore heat preservation is conducted on the steel billet materials on the discharging frame.

This invention discloses a method for preparing and applying crude and homogeneous polysaccharides of *Mesona chinensis* that regulate *Bacteroides*. The method includes the following steps: pulverizing *Mesona chinensis* herb, extracting by reflux with deionized water, filtering out the residue, concentrating to 1 / 4 of the volume, adding ethanol to 80% by volume, stirring evenly, letting stand overnight, centrifuging the precipitate, washing three times with anhydrous ethanol, ethyl acetate, and acetone respectively, dissolving in an appropriate amount of deionized water, and freeze-drying to obtain crude *Mesona chinensis* polysaccharide. The obtained crude *Mesona chinensis* polysaccharide is diluted with deionized water and dialyzed using dialysis bags in the range of 7000D, 100000D, 300000D, and 500000D respectively. The solutions are combined, concentrated, and freeze-dried to obtain homogeneous polysaccharides of *Mesona chinensis* with different molecular weights. The prepared crude and homogeneous polysaccharides of *Mesona chinensis* have good antioxidant capacity and can promote the growth of *Bacteroides* in the gut. In vitro experiments verified that the metabolites of *Mesona chinensis* polysaccharide have good lipid-lowering activity.
