Technical Field

[0001] The utility model relates to the technical field of brick pressing machines, in particular to a special brick pressing machine for aluminum silicon carbide carbon bricks. Background Art

[0002] Aluminum silicon carbide carbon bricks are widely used in molten iron carrying tools in the steel industry, such as molten iron tank linings and torpedo tank linings.

[0003] Chinese patent publication number CN213703832U proposes "a special brick press for aluminum silicon carbide carbon bricks". The technical solution proposes the problem that "the working stroke of the pneumatic cylinder or hydraulic cylinder in the prior art is fixed. Since the formed aluminum silicon carbide carbon bricks are to be used for the lining of molten iron tanks of different sizes, the heights of the formed aluminum silicon carbide carbon bricks are different. When pressing formed bricks of different heights, it is necessary to lift the height of the pneumatic cylinder or hydraulic cylinder as a whole or change the original bottom mold for adjustment. This adjustment method is very cumbersome and time-consuming." The utility model provides the following technical solution: "By rotating the external pressure brick module, the distance between the external pressure brick module and the support plate can be changed, and then the external pressure brick module is fixed by locking bolts, thereby achieving the effect of adjusting the height of the overall brick pressing module to meet the height requirements of different formed bricks."

[0004] The above scheme has the following defects: the mold box structure of the above device is single and cannot be adjusted, and can only press out aluminum silicon carbide carbon bricks of one size, which has poor practicality.

The two side cylinders are retracted to pull the two steel blocks outward respectively, so that the bottoms of the medium bottom mold and the small bottom mold are unobstructed, thereby facilitating the control of the lifting and lowering of the medium bottom mold and the small bottom mold. Then, the materials for preparing aluminum silicon carbide carbon bricks can be filled into the inside of the medium bottom mold and the large bottom mold respectively for pressing, thereby achieving the effect of facilitating the pressing of carbon bricks of various sizes.
