Chapter 39: Still failed

　　 After listening to Song Qingsong’s report, Wang Xudong stood up immediately. He could see that Wang Xudong was interested and waved his hand: "Go, let’s take a look at our new mining equipment."
　　 This time, in order to expand the scale of mining, Wang Xudong put out more than 10 million for the purchase of equipment. Through bidding, this is the first batch of equipment and has now arrived at the mine.
　　 Walking out of the office, Wang Xudong saw the excitement of the mine, and stopped a lot of equipment purchases, and many miners were looking around there to watch.
　　In the past, all the small iron ore mines in the Doulishan area were mining caverns, and equipment like the present one has never been used, because these mining equipment are used for open-pit mining.
　　 "Good guy, this is a large cone drill."
　　 "Old Li, it seems that we will never use percussion drills to make holes again."
　　 "Yes, there is this thing, that punching is a matter of minutes!"
　　 "……"
　　 During the production process of open-pit mine, whether it is stripping or returning the ore, the technological process generally requires perforation, blasting or splitting, loading and transportation. At present, the equipment used in my country's ferrous metallurgical mines is mainly perforated cone drills and down-the-hole drills. Impact drills have been eliminated.
　　In the mine field, percussion drills were used in the past. Workers used percussion drills to drill holes on the mining surface. The efficiency was relatively low. Now it is good. With this advanced large-scale cone drill, the efficiency of drilling is doubled.
　　 is not only a roller cone drill, there are also a lot of equipment next to it, among which the more conspicuous are large crushers, splitters, three-meter electric shovel, 20-ton truck and so on.
The blasting process has been eliminated. The current mining process is to drill first, and then use a splitting machine to break open the iron ore on the mining surface along the drilled hole. The previous splitting machine on the mine was small, and there was only one. It is a large split machine, and two have come.
　　 "Boss, how about it, okay!"
　　 Wang Xudong said happily: "It's too good. With these things, we can change shotguns, and it's more than just mining hundreds of tons of ore every day."
　　 Song Qingsong said loudly: "Boss, I immediately train the workers and teach them how to use these mining equipment."
　　 Song Qingsong is proficient in all kinds of mining equipment, and naturally knows how to use it. In addition, two or three people from the equipment manufacturer also came to train the workers together.
　　Wang Xu nodded and said happily: "Go, use these mining equipment earlier."
　　 Xudong Mining Company is now an excellent supplier of Wujiang Mining. The two parties have an agreement that starting from the next month, Xudong Mining must supply more than 1,000 tons of iron ore to Wujiang Mining Company every day.
　　With these mining equipment, it is estimated that it is not a problem. The supply is estimated to be more than one thousand tons, and one or two thousand tons per day is not a problem.
　　 "It seems that the investment of more than ten million equipment is worth it!" Wang Xudong thought in his heart.
　　 Song Qingsong and the two or three people from the equipment manufacturer, together, began to train the workers and teach everyone how to use these mining equipment.
　　 The mine is full of excitement, and the workers are happy. Starting today, these new mining equipment can be used and the efficiency has improved. Everyone has also changed from manual operations to mechanical operations. Mining will also be much easier.

　　 Wujiang Commercial Plaza.
　　 In the coffee shop on the second floor, by the window, Wang Xudong and Zheng Xiaotong were drinking coffee there. It could be seen that Zheng Xiaotong frowned slightly and seemed to be worried.
　　Wang Xudong also discovered this, and couldn't help asking with concern: "Xiaotong, what's the matter? Is there anything unhappy?"
　　 Zheng Xiaotong sighed slightly in his heart, and slowly said: "Xudong, I'm going back to Beijing, the plane this afternoon."
"Ah!" Wang Xudong was slightly taken aback and didn't think about it. It happened so suddenly, Wang Xudong looked at Zheng Xiaotong and said with a slight reluctance: "Xiaotong, would you like to play for a few more days? There is another famous attraction in Wujiang City. It is also a 4A-level scenic spot. I will take you to take a look."
　　 Wang Xudong couldn't bear to leave Zheng Xiaotong in his heart, and Zheng Xiaotong was the same. Even Zheng Xiaotong didn't even think about it, but he couldn't bear to leave.
Zheng Xiaotong has also been to Wujiang City before. He usually stays for two or three days and leaves. It has never been like this time. After staying for nearly 20 days, he has called several times from his home, if not urged by his mother. Urgent, Zheng Xiaotong still wants to stay for a few more days.
　　 Zheng Xiaotong said leisurely: "Xudong, no, my mother has already called three times. This time she gave a dead order and insisted that I return to Beijing immediately."
　　 Although Wang Xudong felt a little bit reluctant, he knew that Zheng Xiaotong would definitely have to return to Beijing, so Wang Xudong said, "Xiaotong, or else, I'll take you to the airport in the afternoon."
　　 There is no airport in Wujiang City. You have to go to the provincial capital by plane. It takes about two hours by car, which is not too far.
　　 Zheng Xiaotong said straightforwardly: "Yes, I originally wanted my cousin to send me off, but that guy actually said that I was not free in the afternoon, so I was so angry."
　　Thinking of Liu Yu, Wang Xudong felt light and smiled happily, "Xiaotong, next time we meet Liu Yu, let's take a good look at him, but I dare not be free."
　　 Although he knew that Wang Xudong was joking, Zheng Xiaotong pursed his lips and smiled softly, "Xudong, you must remember to call me in the future."
　　 Wang Xudong said: "That's for sure."
　　 After chatting for a while, the two of them felt a lot more relaxed. Although the two were not boyfriends and girlfriends, they both knew that the other had a good impression of themselves. If everything goes well, it is very likely that they will develop into boyfriend and girlfriend friends.
　　 Knowing that Zheng Xiaotong will return to Beijing in the afternoon, Wang Xudong invited Zheng Xiaotong to watch a movie. Zheng Xiaotong happily agreed, and the two watched a movie for the first time.

　　Sanlian Steel Group.
Ding Huixian was full of hope this time. He carried out sampling tests and inspections on this batch of Australian mines, and carefully looked at the various indicators. Although several parameters were not ideal, they were much better than the domestic mines used before, especially sulfur, The index of harmful elements such as phosphorus is much lower than that of domestic mines.
try again.
Therefore, Ding Hui first took his own team and personally guided the workers to make steel. He strictly controlled the process and parameters. Chen Sanlian also knew that this time was very important. Success or failure depends on this. If the use of Australian mines still fails, then The whole project failed.
　　 The atmosphere in the steel-making workshop was tense. In the steel-making control room, everyone looked at the steel spattering in the workshop through the large glass, feeling nervous and excited.
　　 The time seems to be very long. At this time, it seems to pass very slowly. When the smelting is finished and sampling can be checked, many people think that this seems to be as long as a century.
　　 This is because everyone is too nervous and wants to succeed!
　　 Soon, everyone was in the laboratory. The sample was seen very clearly under the electron microscope. Ding Hui first looked at it himself.
At the beginning, Ding Huixian looked happy, and became more and more happy. Everyone thought they had succeeded and was about to cheer and celebrate. However, Ding Huixian's face gradually changed, his brows wrinkled slightly, and he finally sighed. Take a breath.
　　 Chen Sanlian has always been nervous, because Chen Sanlian knows that everyone has put a lot of effort and energy into this topic, and his own Sanlian Steel Group has also used a lot of manpower and material resources to cooperate with the research.
　　 Chen Sanlian frowned when Ding Huixian saw Ding Huixian, and couldn't help asking, "Old classmate, how is it? Did you succeed?"
　　 "Hey..." Ding Hui sighed first, and said with a heavy tone: "Old Chen, we still failed, we failed!"
　　 Suddenly, the whole laboratory was filled with sadness and heaviness.
After a long time, Ding Hui said: "Old Chen, the whole set of smelting processes and various parameters, we have gone through repeated demonstrations and scrutiny, and there will be no mistakes. Now, the key to success or failure is to have high-quality iron ore that meets the requirements. stone."
　　 Chen Sanlian comforted: "Old classmate, or else I will think of a way to help you understand where there are high-quality high-grade iron ore."
　　 Ding Huixian said: "It seems that this can only be done. I also use my relationship to find out everywhere. As long as I can find high-quality iron ore that meets the requirements, I firmly believe that I will succeed."
