Chapter 891： Heavy Industry 1

Aluminum is the third most abundant element in the earth's crust, after oxygen and silicon.

Moreover, the physical and chemical properties of aluminum are very good, suitable for a variety of purposes.

Wu Changqing knew the importance of aluminum in the future industry and life, so he got out the technology of refining aluminum early.

The chemical properties of aluminum are very active, so the reduction is more difficult and the extraction time is relatively late.

Napoleon’s favorite set of tableware was aluminum, but silver tableware was not welcomed by him, because it was much more difficult to make aluminum than silver at that time.

Things are vaguely expensive, and aluminum has been more valuable than silver for a long time.

However, with the improvement of refining technology, its price has continued to plummet.

Nowadays, in Dahua, aluminum doesn't have that kind of bright moment.

After the construction of the Maanshan Aluminum Plant and the large-scale production of aluminum products, the price of aluminum is much lower than that of silver.

Subsequently, aluminum was used in many fields.

In terms of life, a pot made of aluminum for steaming rice is much better than an iron pot, because aluminum has much better thermal conductivity than iron, and aluminum easily forms a layer of oxide on the surface, which will not rust.

In terms of appearance alone, aluminum products are much better than iron products, smooth and silvery in color.

Aluminum pots, kettles, and even pots and pans.

The wealthy can also use aluminum alloy to decorate houses, stair railings, balcony guardrails, and anti-theft windows.

These aluminum alloys are lighter than iron products, and will not rust. They are perfect metal decorations.

These are all embellishments for daily life. With it, it just makes life more colorful. No, everyone's life is also taken care of.

In industry, aluminum products are an indispensable treasure.

Because aluminum alloy is light, it is very useful in cars, trains, and ships.

There are two ways for these vehicles to increase their speed, one is to improve engine performance, and the other is to reduce their own importance.

The demand for aluminum in automobiles and ships is not so strong.

When it comes to building airplanes in the future, aluminum alloy is truly indispensable.

With the deeper and deeper understanding of metals and the use of various metals and alloys, Dahua's industry has also entered an era of heavy industry.

It used to be the explosion of light industries such as textiles, papermaking, and ceramics, which belonged to heavy industries, namely steelmaking and machine tools.

Mainly light industry, supplemented by heavy industry.

Now, Dahua’s light industry is still prosperous. After all, the world is Dahua’s dumping market, which is far from saturated.

However, the imperial court has begun to devote major energy and resources to heavy industry, giving priority to the development of heavy industry. This is the foundation of national power.

There are many other medium-sized steel plants. There is almost one steel plant in every big city with resources and convenient transportation.

However, there are no small steel plants, and the Dahua court does not provide technical support to small plants.

On the one hand, it is low revenue, on the other hand, it is to prevent technology leakage.

The annual output of these medium-sized steel plants ranged from 10,000 tons to 100,000 tons. At the end of the seventh year of Yongxing, the country’s steel output had reached 5.3 million tons, which was equivalent to the original time and space. In 1880, the global steel output sum.

It's exaggerated, but it's a fact.

Dahua's steel industry does not lack resources, manpower, market, and technology.

This is simply the most perfect industrial chain. It is difficult to develop quickly or not. Let a pig be the director of the plant, and the plant can be profitable.

Surpass Dahua and catch up with Dahua?

The emperors of other countries are expected to kneel down and cry bitterly: "The concubines can't do it."

At present, the steel output of other countries is not clear, but it can be inferred based on sporadic intelligence.

The United Kingdom may have 50,000 tons, which is about 1750, which is nearly a hundred years faster than in the original history. This achievement is worthy of pride, provided that you do not compare with Dahua, otherwise the sense of accomplishment is extremely low.

Spain may have about 20,000 tons, France, about 30,000 tons, and the Austro-Hungarian Empire about 10,000 tons. The Ottoman Empire has not yet begun to change. It is estimated that the annual output is only 1,000 tons.

Other countries are also incompetent, not worth mentioning.

The output of all other countries combined is not as good as Dahua's fraction.

Today, the envoys of various countries in Dahua are afraid to send Dahua's development data back to the country, fearing that the emperor of his country will be desperate, and the people of his country will directly kneel down and call Dad.

When a country is strong enough to a certain extent, it is indeed enough to let people from other countries willingly join in as inferior people.

The difference in the steel industry between various countries and Dahua is only the difference in quantity. In other respects, the difference in quality is even greater.

For example, Dahua now has Jinling Machine Tool Factory, Songjiang Machine Tool Factory, Wuhan Standard Machine Tool, Foshan Longchang Machine Tool, and four large machine tool factories.

These standard machine tools are the envy of other countries.

In other countries, there is no large-scale machine tool factory, and the technical content is too high to play.

Not to mention the large ones, there are not many small machine tool factories.

The machine tool is the mother machine of the industry. Without machine tools, there is no way to manufacture high-precision machine parts in batches, and other industries cannot develop.

Without machine tool technology, no matter how much steel is refined, it can only be used to make low-grade goods such as swords, but not high-end goods such as engines.

There are few factories in foreign countries that make machines, but in Dahua, there are several such factories.

Maanshan General Manufacturing Bureau, Wuhu Machinery Factory, Guangzhou Parts General Factory, Jiangning Machinery Factory, Jinling Machinery Manufacturing General Factory.

These are relatively well-known machine manufacturing plants, which have contracted Dahua's various machine manufacturing tasks.

These large factories are only building high-tech machines, and some low-tech machine parts are contracted by various private small factories.

In Nanjing's industrial zone, the entire park is full of such factories, and there are thousands of types of machine parts manufactured, which is dazzling.

When there is demand, human creativity will become infinite.

These various parts did not have Wu Changqing's participation, but the wise laborers still got them out.
