Steel is made like this!University professor conversation elementary school students

"What is the difference between steel and iron?"

"What steps do you need to practice steel?"

"How hard is the steel?"

Recently, at the National Popular Popular Day event at Wuhan University of Science and Technology at the Central Primary School of Xiadian Town, primary school students raised their questions to Hou Yanhui, a professor at the School of Metallurgical and Metallurgical of Metallurgical and Metallurgy.

"The difference between steel and iron is like a hero put on the battle." Hou Yanhui said. Taking "heroes" and "combat clothes" as an example, she tells that when manganese, chromium, nickel, tungsten and other elements are injected into iron forming alloys, they have different performance and play a different role. Under the leadership of Hou Yanhui, the students also explored the steel in life together. Steel -made table legs, stainless steel insulation cups, steel -made large iron doors ... "There are steel everywhere in life." Seeing a variety of steel in the world, students couldn't help but sigh.

Zhao Yi, a member of the teaching group of the School Materials College, will use a series of animations to demonstrate the refining process of steel to the students: the iron ore enters the crusher into a small particle. There are also steps such as blast furnace ironmaking, turntable steelmaking, billet rolling, etc., and then forging to cause steel. Hou Yanhui explained: "Steel is made like this! The iron burned the body in the furnace to make the body shattered into iron water.

At the same time, Hou Yanhui said that people and steel are the same. In the process of growing up, they will encounter setbacks, constantly fall, and after continuous training, they can eventually exercise into those who are perseverance and indomitable.

"It turns out that steel comes like this. To become a steel hero, we have to undergo so many tests. We must use them carefully." Students said.

In the class, the student Zhou Li unexpectedly scratched her legs. Everyone nervously bandaged her wounds, and she didn't cry. Zhou Li pointed at the steel animation played by his fingers: "I want to be as strong as steel. I also want to be a steel hero." Everyone present applauded her.

"Settlement and suffering can make people suffer, but it can make people grow in adversity, consolidate the quality of steel with" toughness, bravery, and connotation. I hope that through the form of popular science, we can not only teach knowledge to students, but also exercise and cultivate their steel -like spirit. "
