Tube sheets are generally cast in sand molds. First, a mold with a certain proportion is made according to the drawing. Then, the mold is placed in a sand box and filled with casting sand around it, which is compacted. After the casting sand is compacted, the mold is taken out, and refractory materials are brushed and dried according to the shape of the mold. Finally, another sand box with reserved sprues is combined with this sand box to prepare for casting.
