被美技术封锁30年，中国用三年打破垄断，造出3.6万吨钢铁巨兽

Core Viewpoint - China has successfully developed a 36,000-ton forging press, breaking a 30-year technological blockade imposed by the U.S. and demonstrating significant advancements in heavy equipment manufacturing [1][10]. Group 1: Historical Context - 30 years ago, China faced immense challenges in acquiring advanced manufacturing equipment, with the U.S. imposing high prices and strict conditions, claiming that China would not be able to utilize such technology [4][6]. - In the 1990s, attempts to purchase such equipment were thwarted by U.S. refusals, citing the sensitivity of the technology and leading to a sense of humiliation among Chinese engineers [6][4]. Group 2: Development Journey - In 2007, China initiated a national effort to develop the 36,000-ton forging press independently, gathering top engineers to tackle the project [6]. - The design process was complex, requiring precise specifications and overcoming significant technical challenges, including the design of hydraulic systems and control programming [6][8]. Group 3: Technological Breakthrough - The forging press was successfully trialed in 2010, achieving operational status in just three years, which was a remarkable feat compared to previous expectations [8]. - The press has a height equivalent to a four-story building, weighs over 22,000 tons, and can exert a forging pressure of 36,000 tons, with precision levels reaching within 0.1 millimeters [8][10]. Group 4: Global Impact and Recognition - The successful production of the forging press has led to a transformation in China's manufacturing capabilities, enabling the production of critical components for large aircraft engines, nuclear power plants, and high-speed trains [10]. - International reactions have shifted from disbelief to admiration, with U.S. and German experts acknowledging China's advancements in heavy equipment manufacturing [10][11]. - China has transitioned from a technology follower to a leader, with the ability to produce such equipment at significantly lower costs compared to foreign competitors [10][11].
