中国新大国重器诞生有15个球场大 可建造10万吨航母
中国新大国重器诞生有15个球场大 可建造10万吨航母

此前，听过一个传闻，不辨真假。传闻是这样，早年中国曾经引进一台钢板轧机，在进行钢材轧制的过程中，消耗了大量的电力，因此造成了大面积停电。之后，专门为了这台轧机的供电，当然也考虑到水利因素，而建造了一座水电站，就是著名的葛洲坝水电站。如果传闻是真，可以看得出，轧机受到一个国家多么的重视，一台强大的轧机就代表一国的重工业水平。
有数据显示，在2003年前投产的26台中厚板轧机中，大多都是2000毫米左右的轧机，而就是这样的轧机都会令国家高度重视。但到了2008年4月15日，一台5500毫米宽厚板轧机在中国第一重型机械集团公司下线，一举打破世界记录，成为中国首台，也是世界首台5000毫米以上的宽厚板轧机。到了2018年，也就是经过了10年，这样的5500毫米的轧机在我国就有十多台，这样的工业能力，足够令世界惊叹，与此同时，世界轧机之王仍然由鞍钢的5500毫米轧机保持，而这台机器足足有15个足球场大，技术水平完全碾压德国与日本。美国与俄罗斯尚不具备生产这一级别轧机的能力。
我们都知道，国产航母最重要的就是国产航母用钢板，而生产10万吨级以上船舶，就需采用宽度4000毫米以上船用钢板。而生产那4000毫米以上船用钢板就需要4800毫米以上的轧钢机。为什么非要用轧机来生产航母用钢板呢？因为10万吨级的航母，必须要确保舰船的强度，而舰船的强度除了钢铁材料的影响外，最重要的就是要尽可能的减少焊缝，以此来增加舰船的强度。减少焊缝就需要大型的宽厚板，而这就需要轧机来进行轧制，使刚才一次成型。就我国未来生产的10万吨级航母003来讲，就需要4800毫米以上的轧机，而这正是我国这10几台5500毫米轧机的应用范围所在。可以说，我国的003在和航母用钢材这一关没有任何阻碍。
在此跑个题，俄罗斯经常听到其正在设计未来的航母，按俄罗斯的话讲，其未来的航母将达到10万吨级，采用双舰岛等优秀的设计思路。但是，就其工业底子来讲，实现这一梦想还有很长的路要走，除非俄方能够采购到宽厚板轧机，或者进口到宽幅中厚板。但是，这两样都属于重要的战略物资，是不会轻易的出口的，因此，俄方的构想还需脚踏实地的一步步来。
宽厚板轧机不仅用于航母的钢板制造，其的用途十分广泛，例如：巨型桥梁结构钢、海上钻井平台结构钢、还有核电站安全壳、大型水坝闸门等等。可以说，但凡需要强度大的特种建筑，都需要宽厚板轧机的参与，因此，称其为国之重器，半点都不为过。
“每一块钢铁里，都隐藏着一个国家兴衰的秘密。”这是美国钢铁大王卡内基的传记作者所说的一句话，而这句话也充分说明了我国目前的复兴盛况！（作者署名：利刃）

China's new power is born with 15 stadiums
China's new power is born with 15 stadiums

Earlier, heard an rumor, not true or false. The rumors are this: In the early years, China once introduced a steel plate mill, which consumed a lot of electricity during the steel rolling process, thus causing a large area of blackout. Later, specifically for the power supply of this rolling mill, of course, considering the water conservancy factors, a hydroelectric power station was built, which is the famous Gezhouba Hydropower Station. If the rumors are true, it can be seen that the rolling mill has received a lot of attention from a country, and a powerful rolling mill represents the country's heavy industry.
According to statistics, among the 26 medium plate mills put into operation before 2003, most of them are mills of about 2000 mm, and such mills are of great importance to the country. However, on April 15, 2008, a 5,500-mm-thick plate mill rolled off the line at China's No. 1 Heavy Machinery Group, breaking the world record and becoming the first in China and the world's first plate mill with a thickness of more than 5,000 mm. By 2018, that is, after 10 years, such a 5500mm rolling mill has more than 10 sets in China. This industrial capacity is enough to make the world amazing. At the same time, the world's rolling mill king is still made by Angang's 5500mm rolling mill. Keep up, and this machine has 15 football stadiums in full, and the technical level has completely crushed Germany and Japan. The United States and Russia do not yet have the capability to produce this level of rolling mills.
We all know that the most important domestic aircraft carrier is the steel plate made by China-made aircraft carriers, and the production of shipboards of 100,000 tons or more requires the use of steel plates with a width of more than 4000 millimeters. The production of steel plates above 4000 mm requires more than 4,800 mm of rolling mills. Why do we have to use rolling mills to produce steel plates for aircraft carriers? Because the 100,000-ton-class aircraft carrier must ensure the strength of the ship, and the strength of the ship in addition to the impact of iron and steel materials, the most important thing is to reduce the weld as much as possible to increase the strength of the ship. Reducing welds requires large, thick, heavy plates, which require rolling mills to perform the rolling just one time. For the 100,000-ton-class aircraft carrier 003 produced in China in the future, a 4800-mm-high rolling mill is needed, which is exactly the application range of the 10 5500-mm mill in China. It can be said that China's 003 is no obstacle to the steel used in aircraft carrier.
In this issue, Russia often hears that it is designing future aircraft carriers. According to Russia’s words, its future aircraft carrier will reach 100,000 tons, adopting excellent design ideas such as double-ship islands. However, in terms of its industrial foundation, there is still a long way to go to achieve this dream, unless the Russian side can purchase a heavy plate mill or import a wide plate. However, these two kinds of important strategic materials are not easily exported. Therefore, Russia’s concept still needs a down-to-earth step.
The heavy plate rolling mill is not only used for the manufacture of steel plates for aircraft carriers, but its uses are very extensive, such as: giant bridge structural steel, offshore drilling platform structural steel, nuclear power plant containment, large dam gates, and so on. It can be said that all special buildings that require high strength require the participation of a wide-heavy plate mill. Therefore, calling it a country’s most important device cannot be overemphasized.
“Every piece of steel hides the secret of the rise and fall of a country.” This is a word spoken by the biographer of Carnegie, the American steel magnate, and this sentence also fully illustrates our current rejuvenation! (Author's signature: sharp knife)
