"Are these sent to Jinghai Shipyard?"

Zhao Xu asked as a donkey cart full of gas cylinders passed by.

After the emergence of hydrogen and oxygen welding, various workshops have great demand for it.

In the past, the riveting was troublesome, the process time was long, and the air tightness was poor, and hydrogen-oxygen welding solved these disadvantages.

At present, in addition to various machinery workshops, shipbuilding workshops naturally have the greatest demand for hydrogen and oxygen welding.

Let hydrogen and oxygen welding replace the riveting of warship iron armor, and the construction speed of iron armor will be greatly advanced.

"Go back to Your Highness, that's exactly." The head of the Iron and Steel Workshop smiled, "In addition, it's the steam engine workshop, the agricultural machinery workshop, etc., and they have also trained some gas welding craftsmen."

Zhao Xu nodded slightly.

When Dasong was leaping towards the power industry, he did not directly destroy the steam industry.

Instead, let the steam industry and the power industry have me and I have you.

It will not be too late to gradually abandon the backward steam industry after the power industry is fully rolled out in Dasong.

The scale of Dasong Industry is not large, and cutting off the steam industry established in recent years is equivalent to cutting off one's own arm.

After leaving the electrolysis workshop, Zhao Xu, accompanied by everyone, went to other workshops and inspected the preparation of steel plates, steel bars, steel wires and special steels with his own eyes.

Overall, Dasong's steel industry level basically reached the mid-to-late 19th century.

"As the first steel workshop in Yancheng, although the progress you have made is obvious to all, you cannot be complacent and continue to overcome more complex steel manufacturing technology." After a round of inspections.

When Zhao Xu left the Iron and Steel House, he turned around and said to the head of the Iron and Steel House.

For steel smelting, the Iron and Steel Floor now has its own research and development team and no longer only hopes for the R&D institute.

After all, the advent of the power industry era means a technological explosion.

The research and development institute can only solve key technologies.

Instead of having to get into anything like the housekeeper.

Therefore, drawing on contemporary experience, he asked the workshop to establish its own research room internally.

The researcher in the laboratory is a skilled craftsman from the workshop, and the other is from Yanzhou University.

The R&D Institute provides them with technical parameters and drawings, and they are responsible for the research.

In order to promote self-research within the workshop, he also asked the workshop to establish an internal night school to teach craftsmen to read, read, read, and basic knowledge such as mathematics, physics and chemistry.

"Yes, Your Highness, we will definitely not lose the name of Yancheng Steel House." said the head of the Steel House.

The steel yards in Shanggu County and Liao County were put into production, forming an internal competition with them.

The Industrial Department often calls together these officials to assess their political achievements.

In this regard, they were also very committed to the affairs of the matter, striving for whom to develop better?

After giving a few more instructions to the head of the Iron and Steel Workshop, Zhao Xu and the officials of the Industrial Department went to the copper industry workshop opposite.

This new workshop area located in the west of Yancheng is all heavy industry.

In addition to steel, there are workshops such as copper, tin, lead, and aluminum.

At the copper industry workshop, Zhao Xu inspected the production of copper wire, copper sheets, copper sleeves and other parts, and then went to the aluminum industry, tin industry and lead industry workshop to observe. Before noon, he went to the rare metal smelting workshop and visited the refinement of tungsten, manganese, lithium, etc.

The rapid development of the metal industry made Zhao Xu feel comfortable.

For military technology, the metal industry is obviously one of the most important technologies.

I stayed in the west of the city for a morning, and in the afternoon, Zhao Xu went to the chemical workshop area in the north of the city again.

After the birth of electricity, chemical technology can usher in a period of great explosion.

Qu Sheng and his students synthesized many compounds that were previously unproductive in a short period of time.

Now, he is working with the Industrial Department to prepare for the industrial production of these compounds.

For example, ammonia.

The large industrial method of ammonia is to synthesize it with high temperature and high pressure using hydrogen and nitrogen.

Since pure hydrogen was unable to be produced before, this was naturally impossible.

With electricity, it becomes possible to manufacture ammonia in industrial use.

Ammonia is widely used and can give birth to more chemical industries.

For example, when nitric acid was used to make, saltpeter was needed, but now it can be prepared directly through ammonia. The cost has decreased and the scale has increased.

After the industrial preparation of ammonia, the Hou's alkali production method invented by the Chinese could also be realized in the early 20th century.

Ammonia, table salt and carbon dioxide can produce soda ash, and no longer need to use alkali ores to obtain soda ash.

At the same time, the by-product of soda ash ammonium chloride is a material for chemical fertilizers.

This is equivalent to establishing a fertilizer industry.

It can be said that as long as you break through one point in the chemical industry, you can break through a series of related chemicals.

The workshops under construction were inspected in the chemical workshop area, and Zhao Xu focused on inspecting various rubber products in the rubber workshop.

He was busy until the evening before he returned to the palace.

The next day, he went to the Light Industry Factory District in Dongcheng again.

Light industry is naturally textiles and food.

After turning on the electricity and replacing the steam engine in the workshop with an electric motor, Zhao Xu's most intuitive feeling was that the output of the textile industry has been greatly improved.

As for the steam engine equipment in textile workshops in the past, they were sold to private merchants, and backward production capacity was also production capacity.

The big song is too big, and development cannot be fully developed at once. You can only choose areas with convenient transportation to focus on development.

Therefore, these phased out steam engines can be transferred to the westward inland areas.

In the light industrial workshop area, Zhao Xu inspected the traditional weaving workshop and spinning workshop, and then went to emerging service trade factories, such as hat workshops, shoe workshops, and clothing workshops.

With the cooperation of the research and development institute and the machinery workshop, the pedal sewing machine was developed last year.

This machinery, which was born in the middle of the 19th century, has a complex structure and can be fully manufactured with the industrial level of Yancheng.

Afterwards, he came to the two key workshops of this inspection.

One is the canning workshop and the other is the battery workshop.

Canned food is related to military supplies. Although it is convenient to carry fried noodles, it lacks nutrition and is a method taken without conditions.

If conditions permit, the soldiers will naturally not be allowed to eat fried noodles.

War is a time-consuming and laborious job, and it is better for the soldiers to eat.

"Your Highness, we are adjusting the equipment and will be officially put into production in half a month." When we arrived at the canning workshop, the head of the canning workshop came up.

The canning workshop consists of two floors, half of which are used to make canned boxes.

That is, tin is plating the thin steel plate provided by the steel mill, and then the steel plate is directly shaped by stamping equipment.

Because the steel plate has high flexibility, you only need to place the steel plate on the mold and press the cylindrical tool of the stamping machine, and the can box will be born.

As for food, you only need to cook it and then heat it to sterilize it, seal the can while it is hot, and a canned food will appear.
