Liu Jianhui sneered disdainfully: "This self-consumable electric arc furnace in the working process of the metal bar itself as the upper electrode, under the action of the current power supply and the lower electrode placed in the mold to produce an arc, the use of the high temperature of the arc to melt the upper electrode itself, and in the water-cooled crystallizer is quickly cooled and solidified, and to obtain alloy ingots, this furnace is especially suitable for smelting titanium, zirconium, tungsten, molybdenum, tantalum, niobium and other active metals and refractory metals, and because it generally works under vacuum, it is called vacuum self-consumable arc furnace, hey, college students, You don't even know such a simple truth, do you? ”

Lu Xin didn't bother to deal with this shameless villain, he turned his head to Professor Lin Tao, his doctoral supervisor: "Professor Lin, you put dozens of metal raw materials in this furnace, if the high-entropy alloy formed by these raw materials together completely loses its conductivity, the upper electrode of this furnace completely fails, and the furnace can emit an electric arc, won't it not work?" ”

"Completely lost conductivity? High-entropy alloys are fully insulated and fully resistive? Lin Tao's eyes widened in surprise: "High resistance is indeed a major feature of high-entropy alloys, I want to find high-entropy alloys with high resistance characteristics, but high-entropy alloys are still metals after all, not plastics, and cannot have complete resistance characteristics!" ”

Lu Xin's words woke up the people in the dream, and the doctors brought by Lin Tao also talked about it, and what they talked about the most was whether the high-entropy alloy formed in the furnace would become an ultra-high-resistance alloy.

There are dozens of different high-resistance alloys in alloy materials, which are used to manufacture resistive components, such as nickel-chromium-aluminum-iron, nickel-chromium-aluminum-copper, nickel-chromium-manganese-silicon, nickel-manganese-chromium-molybdenum alloy, which are not mainly used to conduct current, but to limit or control the current in the circuit with its high resistance, such as resistive elements and resistance wires used in motors, potentiometers, standard resistors, potentiometers, and slip wire resistors; Resistive alloys for the manufacture of sensing elements that reflect parameters such as strain, temperature, magnetic field, and pressure; Resistive elements in temperature compensators and temperature measuring resistors.

Lu Xin also realized from their discussion that there was a slight error in his words just now, and said with a smile: "What I said may not be a complete resistance, but an ultra-high resistance, the resistance characteristics are close to ordinary insulating materials, if the professor does not believe it, he can take out a part of the high-entropy alloy solid to do the resistance experiment." ”

The furnace has been powered off for more than ten hours, and it has long been cooled, so those doctoral students still carefully stopped vacuuming, and then destroyed the vacuum, and then loosened the connecting bolt between the lower electrode and the crystallizer, started the ingot dragging device, and dragged out the ingot formed by the high-entropy alloy alloy alloy and put it into the instrument for resistance testing.

The test results were as Lu Xin expected, the resistance was super high, almost close to the insulating material.

Now everyone understands that because the dozens of metal raw materials form a high-entropy alloy with ultra-high resistance in the furnace, the metal raw materials cannot become electrodes in the self-consuming electric arc furnace, and the electric arc furnace naturally cannot work normally without electrodes.

The mechanics who repair the equipment and the personnel who manage the equipment only understand the equipment, but do not understand the properties of high-entropy alloys, and the people responsible for the research of high-entropy alloys do not understand the equipment, and the two groups of people have no active communication together.

Lu Xin just probed the metal characteristics of the high-entropy alloy in the furnace, and found that the metal molecule structure inside was much looser, there were large faults between the metal molecules, and there were mostly impurities between the molecules, so he boldly put forward the hypothesis of ultra-high resistance.

Lin Tao looked at Lu Xin appreciatively, stepped forward to hold Lu Xin's hand tightly, and laughed loudly: "Lu Gong, if you hadn't reminded us, I'm afraid we would have drilled the tip of the horns, entered a dead end, and wasted time in vain, it's really too xiexie!" ”

Lu Xin was very suspicious that it was because he fell into the furnace yesterday afternoon and absorbed the special energy in the metal substance, so that the molecular structure of the metal in the high-entropy alloy was sparse, and the conductivity of this high-entropy alloy was extremely reduced, so he reminded Professor Lin: "The conductivity or resistance of this ratio of high-entropy alloy may not be very stable, why don't you do another experiment in the same proportion?" ”

Lin Tao agreed with Lu Xin's judgment, so he asked people to put in dozens of different metal materials according to the original proportion, turn on the power supply, connect the waterways of each vacuum pump, vacuum, and then connect the waterways of each cooling point, prepare for smelting, and then start test smelting, and found that the furnace can run normally again.

"I see! Well done! Jiang Chunyu couldn't hide her excitement, she clenched her fists and hammered Lu Xin's chest.

It turned out that Jiang Chunyu had planned for the worst, and reported the news of the unfavorable maintenance of the vacuum self-consumable electric arc furnace worth five million to the group company, and accepted the criticism and punishment of the group company, but he didn't expect Lu Xin to turn the tide and prove that there was no problem with this machine.

Lu Xin touched his aching chest, is this woman also from a mechanic, how can she have so much strength, but looking at her fine skin and tender meat, she doesn't look like she was born as a mechanic.

He touched his slightly swollen face again, and glanced at Jiang Chunyu, who was so excited that his cheeks were flying, and suddenly felt that she was a little familiar, as if he had met him before.

He hollowed out his mind and thought for a while, and finally remembered, as if he had seen it at his alma mater, Jiangnan University of Science and Technology, she seemed to be a teacher at the University of Science and Technology, how could she come to Sanjiang Group?

Lu Xin dared to ask: "Vice President Jiang, have you worked at Jiangnan University of Science and Technology before?" ”

Jiang Chunyu'e frowned: "How do you know?" ”

Lu Xin put on a sunny smile: "Vice President Jiang, I went to Jiangnan University of Science and Technology in college, and I have seen you in school before!" ”

"What level are you?" Jiang Chunyu stared at Lu Xin suspiciously, as a beautiful woman who was often harassed by men, she never took any man in her eyes, let alone a passerby like Lu Xin, she had no impression of Lu Xin at all.

"Teacher Jiang, I'm from the 09th grade of the Mechanical College!" Lu Xin slowly remembered that Jiang Chunyu seemed to be the teacher of the Mechanical College.

Jiang Chunyu's eyes turned cold again when he looked at Lu Xin: "There are two people from your academy last year, one is Ma Changle and the other is Xie Fei, it seems that there is no you!" She thought Lu Xin was lying.

"A few months ago, there was a vacancy in the company, and I was in a hurry to ask for someone, so I jumped ship!" Lu Xin wrote lightly, he didn't want to say that Jiang Xueqing introduced him through the back door.

"I see!" Jiang Chunyu's eyes had a hint of warmth, she chuckled, clenched her fists again, and punched Lu Xin: "I didn't lose the face of our school, do a good job!" ”

Jiang Chunyu turned around and communicated with Professor Lin Tao about the aftermath and ignored Lu Xin.

Lu Xin looked at Jiang Chunyu's back, touched his swollen face again, picked up the mobile phone screen and took a photo, there were still clear five finger prints, this cold and arrogant woman didn't seem to have been slapped by her yet, hmph, sooner or later, Lao Tzu will have to get this slap back, or let you pay the price you deserve!
