Large-scale high-end continuous casting and rolling mill sets:
These sets of equipment have extremely high requirements for precision, stability, and automation, making the cost of integrating the entire line very high.
Core characteristics: The entire line includes multiple core sub-equipment such as continuous casting machines, rolling mills, automated control systems, and online detection systems. It requires customized design and manufacturing based on the enterprise's production capacity and product specifications, resulting in extremely high technological barriers.
Estimated cost: The total investment for a newly built high-end plate and strip continuous casting and rolling production line can typically reach several billion yuan, with the purchase cost of core main equipment accounting for more than 40% of the total investment.
Ultra-large electroslag remelting furnaces/vacuum metallurgical equipment:
These are ultra-large pieces of equipment used for the production of high-end special steel and large forgings, with extremely high manufacturing difficulty and cost.
Typical case: The 450-ton electroslag remelting furnace at Shanghai Heavy Machinery Plant in China was the world's largest of its kind at the time. The investment in its independent research and development and the cost of the equipment itself were far higher than those of conventional metallurgical equipment.
Cost Logic: These types of equipment need to withstand high temperatures and pressures, requiring extremely high material purity and machining precision. They are also highly customized, with very low production batches, thus significantly increasing the cost per unit.
Large-Scale, High-Precision Metallurgical Machine Tools
Ultra-large boring and milling machining centers for processing large metallurgical components, ship engines, and high-end forgings can reach prices in the hundreds of millions of yuan.
Typical Case: Large floor-type boring and milling machining centers exceeding 5 meters in length manufactured by German companies are priced at over 100 million yuan. These machines have extremely high requirements for machining precision, rigidity, and stability, resulting in very high R&D and manufacturing costs.
Industry Perception: It is generally believed in the industry that high-end metallurgical machine tools exceeding 5 meters in length are generally priced in the hundreds of millions of yuan range and are recognized as expensive metallurgical auxiliary equipment.
