Chapter 1: How Steel is Made.

1 The history of steel refining can be traced back to ancient times, and after thousands of years of improvement, the process has changed dramatically.

2 The basic process of iron and steel refining is to heat a raw material called "iron ore" to a high temperature with coal, so that it can undergo a chemical reaction, so as to extract iron from it, and then add various elements, such as manganese, aluminum, etc., to adjust the physical properties of the material, and finally form the steel we know well.

3 The modern steel bumper iron refining process includes: element mixing, smelting, casting, etc., each step is crucial and directly related to the quality and performance of the final product.

4 Modern steelmaking also requires a great deal of equipment and technology, among which computer technology plays an important role in improving the quality and performance of steelmaking.

Chapter 2: Properties of Steel.

1 The properties of steel are determined by its composition, and the common steel components mainly include: carbon, silicon, phosphorus, manganese, aluminum, zinc, vanadium, chromium, etc.

2 Different steels contain different elements and therefore have different properties, for example: carbon steel has good ductility and toughness; Alloy steel has higher strength and corrosion resistance; Special steels have excellent thermal strength, etc.

3 The properties of steel are also affected by the heat treatment, which can change the microstructure of steel and improve its mechanical properties, such as improving strength, wear resistance, destructibility, corrosion resistance, etc.

4 The properties of steel will vary depending on the environment in which it will be used and its quality, therefore, when selecting and using steel, the environment and quality of its use should be considered to ensure the quality and performance of the product. Hope.

Writing ideas: First of all, write about the feelings of reading the book "How Steel is Made", briefly introduce the protagonist in the book, connect with the reality of life, and express your own opinions.

Text: When I finished reading the book "How Steel is Made", I couldn't help but be moved to tears, as if there were thousands of waves in my heart hitting my heart one after another.

I remember Gorky's famous saying: I feel that when books give the feelings, thoughts and attitudes of characters that Russia has never heard of or seen, it seems that each book opens a window in front of me and allows me to see an incredible new world. This book not only gave me a new world, but also gave me a blue sky of my own.

Paul, the protagonist of this book, was born into a poor family in Ukraine. At the age of 11, he worked as a child laborer in the station canteen, joined the Communist Youth League in 1919, and then fought in the civil war. 1923 In 1924, Paul served as the leader of the Komsomol in the border regions of Ukraine, and in 1925 he joined the Communist Party.

However, due to his long-term participation in the arduous struggle, his health was seriously damaged, but he finally fought against the disease tenaciously, and later he not only defeated the disease with his will stronger than steel, but also wrote the world literature masterpiece ** "How Steel is Made".

Connect with the reality of life. Today's children don't want to let them work as child laborers to subsidize their families, even if they are allowed to wash dishes and cook at home, they are not willing. In their "account" there has always been no in, only out.

This is not because of the rapid development of the country, but because of the doting of parents.

The children are like little princesses and little emperors at home, and they will only spend money to buy some things that they don't like to go home, and they even treat their parents as slaves. If there is no big fish, orange or meat on the table, or no favorite dish for you, you lose your temper, cry and make trouble, and don't eat. Like our parents' generation, it's good to have food.

And the children will say that the times are different, but now the children in the mountainous areas only eat sweet potatoes and dried sweet potatoes, and they still take the first place in the class. And our children here want the wind to be the wind, the rain to be the rain, eat big fish and meat every day, and have everything they want, but why have their grades not been high? This is because they are not self-motivated, soak in sugar water all day long, and forget what bitterness tastes like.

Paul was blind and quadriplegic, but he still wrote a masterpiece of literature. Even if a child of my generation asks him to write an essay, he will frown, and when he talks about surfing the Internet, playing games, and watching TV, he will say that he is not willing to do homework or read books at all, and he knows how to play all day long.

I really hope that the children in the mountains can be swapped with the children here, so that the children here do not know the blessings in the midst of blessings. I have benefited a lot from this book, "How Steel is Made", and I think this book will inspire me to move forward!

The most precious thing for a human being is life. Everyone has only one life. A person's life should be spent like this:

When he recalls the past, he will not regret that he wasted his time, nor will he be ashamed of his inaction. On his deathbed, he was able to say that his life and all his energies were devoted to the greatest cause in the world--- the struggle for the emancipation of mankind.

This is a quote from Ostrovsky, the author of "How Steel is Made", --- Ostrovsky. This sentence made me unable to calm down for a long time. The protagonist of "How Steel is Made" --- Paul.

Isn't Kochagin that? His life and all his energies were devoted to the greatest cause in the world--- the struggle for the liberation of mankind. How much his spirit is worth emulating.

Paul. Kochakin, when he was a child, was often bullied by powerful children, but one day, he met Zhu Helai, who taught him a few simple boxing moves so that he was no longer bullied by others, and it was Zhu Helai who transformed him from an ordinary child into a hero in the struggle for the liberation of mankind.

After Paul joined the army, he was wounded, so he was often unwell, but he persevered, and as soon as he came out of the hospital, he asked for a job arranged for him. Eventually, he was paralyzed in both legs due to overexertion, and injuries sustained during the battle, and soon became blind again. How painful this is for ordinary people, but he resolutely chose the path of literature.

Eventually, as a result of his efforts, one of his books, Children in the Storm, was published.

In life, you will encounter all kinds of misfortunes, setbacks, and difficulties, but as long as you work hard to overcome them, you will succeed. A slave who is not worthy of fate, if he is not defeated by it, will have a spirit like Paul's. Let's work together. Strive to create more miracles!

Reading "How Steel is Made" has a feeling.
