Application of aluminum dihydrogen phosphate in riser cutting process

The riser cutting process is to place a cutting piece made of refractory material at the joint of the riser and the casting, and the riser can be easily removed from the casting after sand falling. The molten steel in the riser feeds the casting through the central hole of the cutting piece, so the size and shape of the central hole of the cutting piece have a great influence on the feeding of the riser.

The production test of the easy - to - cut piece made of waste silica brick particles and aluminum dihydrogen phosphate binder shows that the riser head is easily separated from the casting from the neck by hammering the riser head after the casting has fallen sand. In this way, the labor intensity of workers is greatly reduced, the cleaning time is reduced, and good benefits are obtained.
