Steel, like grain, has made great contributions to supporting the rapid development of the national economy. my country has become a big manufacturing country, and the iron and steel industry has contributed a lot. The iron and steel industry has played a great role in supporting and promoting national defense, petroleum, shipbuilding, construction, and equipment manufacturing. When the People's Republic of China was founded in 1949, there were only 158,000 tons of steel in our country. After several generations of hard work, when the Republic was founded 70 years ago, our crude steel output has ranked first in the world for 24 consecutive years. After the reform and opening up, the biggest event in my country's iron and steel industry is the construction of Baosteel. It can be said that the completion and operation of Baosteel has not only brought my country's iron and steel industry, but also the comprehensive strength of the industry to a great level. The construction of the """"One Belt, One Road"""" has brought huge opportunities for steel to """"go global"""" at a higher level. Steel has become one of the most competitive industries in my country in the world, so it has the strength to go international and integrate into the world. It will play a more important role in the research and development of advanced steel materials and new powder metallurgy materials.
