Recently, "the strongest brain" Central South University and the "shield giant" iron construction heavy industry marriage. What kind of spark will this shine? What kind of story will be created? It is bound to create an "iron-tooth steel tooth" that exerts the best performance of "Pangolin"!

At this time, friends may ask: Is this "Pangolin" awkward? What is the "iron tooth steel tooth"? In fact, this is the main body of the "Pangolin" name is the shield machine! Then, what is the shield machine used for? As one of the main equipments for urban tunnel construction, it is naturally used to “make holes and swallow”! And this "Pangolin" has to "make holes and swallow the soil", and it is indispensable to rely on the "iron-tooth steel teeth" of the cutter head - the carbide turning tool.

At this time, friends may have to say it again, I have never seen it, or you have to talk about it. This has to be said from the subway that every friend may sit on every day or two. As we all know, the subway has entered our lives, bringing convenience and speed to our trips. How can we not be concerned? It’s just that we are not paying attention to the point, right? For example, many friends in Xiamen should know that Xiamen Metro Line 1 has been opened for the first anniversary! This brings convenience, who sat, who knows, from time to time, there are seats, very happy, there are wood! Also, everyone is more concerned about the opening of Metro Line 2, Line 3, Line 4, Line 5 and Line 6? Oh, then, where am I...

However, next, I want to share with you the "Pangolin" and "Iron Steel" that I have learned. They are very close to you and close to me. On March 28, 2018, the first shield machine of Xiamen Metro Line 4 project was successfully launched, which marked the beginning of the construction of the expressway around the island of Metro Line 4. It is said that Line 4 is currently the “fastest running” line in the Xiamen subway system.

However, have you ever noticed that this "Pangolin" is a "foreign species" or is it "born?" In fact, whether it is Beijing, Shanghai, Shenzhen, or Nanjing, Hangzhou and other cities, a large number of shield machines and special carbide tools have been introduced. This, the subway project is the use of advanced shield construction technology, but the equipment is not their own, and ultimately it is not easy to use. First of all, the hurdle in the heart is not good.

As you may know, Central South University has academic advantages in new materials, rail transit, construction machinery, electronic information, and intelligent manufacturing. If these "strongest brains" can make full use of what they have learned, this will provide technical support for the implementation of Tiejian Heavy Industry's technological innovation and engineering projects. However, in fact, the "marriage" between Central South University and Tiejian Heavy Industry is based on "feelings". Previously, the two sides jointly completed the research of several national, provincial and municipal scientific research projects such as the National 863 Program “Research and Application of Key Technologies for Large Diameter Full Section Hard Rock Tunnel Excavation Equipment (TBM)”.

Therefore, this time, Central South University and China Railway Construction Heavy Industry Group signed an industry-university-research cooperation agreement in Changsha to carry out joint research in key infrastructure parts such as cemented carbide materials and shield cutters. This is an exciting start – driving the key Materials and core components will be autonomous and localized, and the shield cutter industry will be strengthened and strengthened, and the industry will be transformed into a high-end transformation and intelligent manufacturing will be realized. The author believes that this will also have an exciting result, fully realize the independent manufacture of key materials and core components of the shield machine!
