Composition and Properties of Manganese Steel
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.

1. Offshore Oil and Gas Exploration In the oil and gas industry, submarine hammer drilling is crucial for the installation of subsea pipelines and wellheads. The ability to efficiently penetrate the seabed allows for the secure placement of infrastructure that can transport hydrocarbons from extraction points to processing facilities.
Applications of the ZJ Slurry Pump
When the crawler pile driver is drilling, the current of the pile driver's ammeter shall not exceed 100A. If the ammeter current exceeds 100A, the drill pipe should stop and descend slowly, and the rotor always keeps turning. If the current drops below 100 amps and is stable, the drill pipe can continue to decline slowly.
