Roller conveyor shot blasting machine, steel plate preservation line, sand blasting room are the most commonly used equipment in shipbuilding industry. Steel plate shot blasting machine can blast steel plate, h beam and small steel structure, while sandblasting room can blast the body of the ship, the steel structure of the ship and other big parts. The preservation line is a piece of the necessary equipment in every shipyard. It can blast steel plate, paint it and dry it.
Why are shot blasting machines used in the shipbuilding industry?
In the shipbuilding industry, shot blasting machines are core and critical equipment for ensuring the quality and lifespan of ships. Simply put, shipyards use shot blasting machines to solve a fundamental problem concerning the survival of ships: preventing the steel hull from being rapidly corroded by seawater.
A giant ship sailing in the harsh marine environment will have its steel surface rust and corrode in a very short time if it is not treated, seriously threatening structural safety. Shot blasting machines are an indispensable tool to address this challenge.
What types of shot blasting machines are needed for which components in the construction industry?
components | Purpose | Blasting Machine type |
Marine steel plates and sections | It efficiently removes rolling mill scale and sea salt corrosion, creates uniform anchor patterns, and directly applies temporary anti-corrosion primer. With a high degree of automation, it is an essential component of large shipyard production lines. | Roller Coveyor Shot Blasting Machine ( Steel Pretreatment Line) Features: By integrating fragmented and inefficient processes into a high-speed automated production line, a single steel plate can be processed continuously at a speed of 1 to 6 meters per minute, a feat unmatched by traditional manual methods. |
Marine steel plates, structural steel (angle steel, channel steel, I-beams), steel pipes | Removes stubborn adhering sand, oxide scale, and welding slag; simultaneously, the impact force eliminates surface stress and improves fatigue strength. | Hook-type Shot Blasting Machine Features: For irregularly shaped "hard nuts to crack," the workpiece is hung on a hook and lowered into the shot blasting chamber for a comprehensive "shower" cleaning, which is flexible and efficient. |
Giant hull sections | Before segmented painting, all areas on the inner and outer surfaces of the segments, such as welds and free edges, that cannot be covered by the pretreatment lines are thoroughly sandblasted. | Sandblasting Booth Features: Capable of performing efficient and environmentally friendly overall rust removal on extra-large, irregularly shaped ship hull sections in a completely sealed, negative-pressure environment, a capability that other mobile or walk-through equipment cannot match. |
