The main components of submarine hammer drilling equipment include the drill rig, hammer, drill pipes, and the drill bit. The drill rig is often mounted on a surface vessel or a floating platform and is designed to support the excessive weight and dynamic forces encountered during drilling operations.

Down-the-hole hammer drilling is a technique used primarily for drilling boreholes in hard rock applications. It employs a pneumatic hammer, situated directly at the drill bit, to deliver high-impact blows that effectively break up the rock. This method contrasts with traditional rotary drilling, where the drill bit operates at the surface and relies on torque and weight to penetrate the ground.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
