The Application of Abrasive Blasting Machines in the Shipbuilding Industry
The application of abrasive blasting machines in the shipbuilding industry is indispensable. It is more like a thorough "cleaning and rust removal" process for the "sea monster" - the ship, during its construction and maintenance, and also a process of applying a sturdy "rust-proof armor" to it.
The abrasive blasting process runs through the entire process from raw material steel plates to the formation of the ship and its long-term maintenance. I divide its main application scenarios into
three core application scenarios for detailed explanation
Steel plate pre-treatment: The transformation from "raw material" to "reliable base material"
This is the largest-scale and most automated abrasive blasting application in the shipbuilding industry. On the dedicated steel plate pre-treatment production line, the abrasive blasting machine or the pre-treatment line abrasive blasting machine is the core equipment. Whether it is a horizontal or vertical abrasive blasting machine, they all operate with extremely high efficiency to thoroughly clean the incoming raw steel plates. This process directly determines the lifespan of the subsequent coating and is the first and most crucial step in ensuring the long-term corrosion resistance of the ship. For example, the newly投产's wide-thick steel plate pre-treatment line in Wuhan Shipyard is specifically built to meet the strict requirements of ship and marine steel products.
Large components and sections processing： Protecting the "heart" and "bones"
When the steel plates are cut and welded into ship sections or manufactured into key components such as ship engines, abrasive blasting machines make their appearance again. For example, the truck-mounted abrasive blasting machine that can handle components weighing up to 200 tons is the main force for handling these "big guys". They can effectively remove the oxide scale and stress from the surfaces of key components such as diesel engine cylinders and crankshafts, and can also perform overall or local treatment on the formed ship sections to ensure that all structures are in the best preparation state for coating before closing.
Mobile operation： Providing convenience for the lifelong maintenance of "giant ships"
After the ship is closed or during its long-term operation and maintenance, fixed large-scale equipment cannot operate on the entire ship. At this time, flexible mobile or dedicated abrasive blasting equipment shows its value. For example, the remotely controlled deck abrasive blasting robot can move autonomously, avoid obstacles, and perform efficient rust removal and paint removal operations. In ship repair, the sandblasting process (using mineral sand) is usually used to operate on the formed ship body to remove old paint and rust layers, preparing for re-coating.
New industry trends： Intelligence and Automation
In recent years, the application of abrasive blasting technology in the shipbuilding industry has also shown a significant trend of intelligence and automation：
Robot replacement of manual labor： To address the problems of high labor intensity, low efficiency, and health hazards in the rust removal of large planes such as decks, deck abrasive blasting robots have emerged. They adopt wireless remote control or autonomous guidance and can achieve Sa2.5 level cleaning requirements. Their efficiency and environmental protection far exceed manual labor.
Intelligent equipment overcoming challenges： For traditional processing problems of large and complex components (such as ship body surfaces), domestic researchers have developed intelligent sandblasting robots integrating "intelligent eye + planning brain + anti-shake heart". It can automatically recognize the three-dimensional model of the workpiece, plan the optimal path, and complete the operation with extremely high stability, increasing production efficiency by 35% and the compliance rate of cleaning quality to 98%, providing a reliable "protective suit" for large-scale heavy equipment such as ships. Overall, the application of shot blasting machines in the shipbuilding industry has evolved from merely being a rust-removal tool to a comprehensive technical system that integrates material pre-treatment, structural strengthening, and automated maintenance. It is a crucial part in ensuring the lifespan and safety of ships.
