Chapter 891: Heavy Industry 1

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

Moreover, aluminum has good physical and chemical properties, making it suitable for many purposes.

Wu Changqing knew the importance of aluminum in the industry and life of later generations, so he developed the technology of refining aluminum early on.

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

Napoleon's favorite set of tableware was aluminum products, but silver tableware was not favored by him because it was much more difficult to obtain aluminum than silver at that time.

Rare things are expensive, and aluminum has been worth more than silver for a long time.

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

Now in Dahua, aluminum does not have that kind of bright moment.

After the Ma'anshan Aluminum Plant was put into construction and aluminum products were produced on a large scale, the price of aluminum was much lower than that of silver.

Subsequently, aluminum has been applied to many fields.

In terms of life, aluminum is much better than iron pans for steaming rice, because aluminum has much better thermal conductivity than iron, and aluminum is easy to form 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 silver in color.

Aluminum pans, kettles, even pots and pans.

Rich people 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, making them perfect metal decorations.

These are the embellishments of daily life. With them, it just makes life more colorful. Without them, everyone’s life is also taken care of.

In industry, aluminum products are indispensable treasures.

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

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

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

When it comes to building aircraft in the future, aluminum alloys are truly essential.

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

In the past, it was the outbreak of light industries such as textiles, papermaking, and ceramics, which belonged to heavy industries, that is, steelmaking and machine tools.

Mainly light industry, supplemented by heavy industry.

But now, Dahua's light industry is still prosperous. After all, the whole world is Dahua's dumping market, which is far from saturated.

However, the imperial court has begun to devote its main energy and resources to heavy industry, giving priority to the development of heavy industry, which is the foundation of national strength.

There are so many other medium-sized steel factories. Almost every big city with resources and convenient transportation has a steel factory.

There are no small iron and steel factories, and the Dahua court does not provide technical support for small factories.

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

The annual output of these medium-sized steel plants ranges from 10,000 tons to more than 100,000 tons. At the end of the seventh year of Yongxing, the national steel output has reached 5.3 million tons, which is equivalent to the original time and space. In 1880, the global steel output sum.

It's an exaggeration, but it's true.

Dahua's steel industry has no shortage of resources, manpower, market, or technology.

This is simply the most perfect industrial chain. It is difficult not to develop rapidly. Letting a pig be the factory manager can make the factory profitable.

Surpass Dahua, catch up with Dahua?

The emperors of other countries probably knelt down and cried bitterly: "The concubine can't do it."

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

The UK 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. The premise is not to compare with Dahua, otherwise the sense of accomplishment will be 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 started to change, and the estimated annual output is only 1,000 tons.

Other countries are also not in the stream, not worth mentioning.

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

Today, envoys from various countries in Dahua are afraid to send Dahua's development data back to their country, fearing that the emperor of their own country will despair, and the people of their own country will directly surpass Dahua and kneel down and call Dad.

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

The gap between various countries and Dahua in the steel industry is only a quantitative gap, and in other respects, the qualitative gap is even greater.

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

These standard machine tools are the envy of other countries.

In other countries, there is not a single large-scale 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.

And the machine tool is the mother machine of the industry. Without the machine tool, 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 smelted, it can only be used to make low-level goods such as swords, and cannot make high-end goods such as engines.

There are almost no factories manufacturing machines in foreign countries, but in Dahua, there are several such factories.

Made in Ma On Shan

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

These are relatively well-known machine manufacturing factories, and these factories have contracted Dahua's various machine manufacturing tasks.

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

In Nanjing's industrial zone, the entire park is full of such factories, producing thousands of various types of machine parts, which is dazzling.

When there is demand, people's creativity will become infinite.

These various parts did not have Wu Changqing's participation, but those laborers full of wisdom still got them out.
