Two days later, as soon as Shi Yiwen returned to the factory, he immediately organized the factory to start molding the iron wellheads of the pressurized water wells, which were different from the sand mold casting in the deep state. Because mass production was required, iron mold casting was used instead.

The iron mold is not a new technology, as early as the Spring and Autumn Period and the Warring States Period, it has appeared in the iron fan casting, which has an iron farm tool model, which is exquisitely made, has a perfect structure, and has a very high level of craftsmanship. Until now, iron molds have been used for large-scale castings such as pots and farm tools in various places.

Because there was no technical difficulty in the pressure well, with molds and sufficient iron, hundreds of them were cast in just one day.

"Now we can make 600 pieces a day, and at this output, we can cast about 20,000 ...... a month."

After a moment of silence, Shi Yiwen shook his head and said.

"The output is still lower, since it is a disaster relief object, we have to rush the time, so add some molds, let the workers work overtime, and strive to make more than 2,000 a day, so that 60,000 can be made in a month...... Even if it's 60,000, it's still not much. ”

Shi Yiwen sighed, at this time, he missed the industrial capacity in another time and space, which made people envious and hateful.

"There are more than one million households in Beizhili, and there are almost hundreds of thousands of people affected by the disaster, hey, it can only be said that it is barely enough!"

The strength of an individual is always limited, and the strength of a factory is also limited, even if all the production capacity of the Lugou Iron Factory is used, it is impossible to meet the needs of Beizhili, in the face of such a reality, Shi Yiwen also seems a little helpless.

"Childe, even if you make 60,000, you can still live millions of people, which is also a great merit,"

Xu Sicheng looked at Shi Yiwen who looked helpless and said.

"Besides, didn't you ask the book building to engrave the "Pressurized Water Well Law" there? In a few years, this pressurized water well will definitely become popular in the world. At that time, the people of the world will also benefit from it. ”

The world is alive...... Xu Sicheng's words reminded Shi Yiwen of the great drought in Chongzhen decades later, the extraordinary drought in Shaanxi that has not rained for several years, and the pressurized water well with a depth of less than 11 meters is only 11 meters by relying on the well, is it useful?

But then, he thought of another possibility, maybe in a few decades, with his own efforts and the level of technology, he may have been able to drill deep wells with steam engines, or even diesel engines to pump water. By that time, the depth of the shaft could reach hundreds of meters.

"I hope so."

Nodding silently, Shi Yiwen glanced at the drawings, and then said.

"What is the casting cost of our factory now?"

"Hui Gongzi, a well with 31 catties of iron 627 yuan, the market price of a pound of iron is one cent of silver, although the cost of the iron of the Zunhua Iron Plant used in our factory is 50% lower than the market price, but in terms of pricing, it is still purchased at the market price, so the iron price is three dollars and one cent and six cents plus iron coke and labor costs, the cost of a well head does not exceed four dollars and two cents, and the ex-factory price I initially set is one or two dollars and five cents."

When Xu Sicheng came out of the overall cost of the well one by one, Shi Yiwen pondered for a moment and then said.

"Our cost is less than five dollars of silver, because the cost of our chemical iron is low, I calculated when I was in Shenzhou, the cost of the folk blacksmith shop casting, the cost will not be less than eight dollars, we sell one or two dollars, the profit of the blacksmith shop will be much less, now what we need is that they will produce nearby, so that as many people as possible can benefit in a short period of time, so we can increase the ex-factory price, so that the blacksmith shop has profits, they will cast the wells, they can profit from it at the same time, so that more people can benefit."

Sometimes, product pricing does not necessarily follow market rules, just like in World War II, Japan raised the price of weapons by 10% in order to mobilize private enterprises to produce arms, so as to stimulate the enthusiasm of private enterprises to produce arms. And during the period of preparation for war, the state procured weapons from local mobilization lines, and even some products were used at twice the high price of regular arsenals.

Now the goal of raising prices is to increase the profits of "small enterprises", so that they can have enough enthusiasm to invest in the production and manufacturing of wellheads, so that more people can benefit.

"I understand, in this case, the final price of the well head is almost two taels, plus the cost of drilling the well, it should not exceed two taels or three dollars...... The people can afford it. ”

Nodding in agreement, Xu Sicheng said again.

"Childe, it is estimated that a lot of iron will be needed in various places at that time, and I think the output of the iron factory can be increased somewhat, after all, a well will cost dozens of catties of iron, and millions of households, if every family drills a well, the iron needed at that time will be an astronomical amount."

"Hmm."

Responding lightly, Shi Yiwen smiled.

"In fact, we can also make a lot of profit by selling iron."

In fact, it is just casually said that compared with the profits obtained by the well, Shi Yiwen pays more attention to the many benefits that pressurized wells bring to the people of the world.

"When the people in the north have pressurized water wells, the people in the north will no longer rely purely on the sky to eat, small drought worry-free, big drought to make a living, when the time comes, our cotton cloth and other products sales, will also increase, well, even ......"

Suddenly, as if thinking of something, Shi Yiwen was silent for a moment, and then said.

"Even we can make fertilizer, with the help of fertilizer, not only the yield of crops can be doubled, and even double cropping a year will be very common, wheat in winter, corn in summer, ......"

Thinking of the common double-cropping operation on both sides of the Yellow River in later generations, Shi Yiwen naturally thought of the crop specimens in the Agricultural and Animal Husbandry Research Institute in the space, and maybe those specimens could be taken out for breeding this year. Although the number of crop specimens such as wheat, rice, and corn is small, as long as they are slowly multiplied, the yield of crops can be doubled in a few years.

"Making fertilizer?"

Xu Sicheng is no stranger to corn, and the grain it uses may have been originally only grown in places like the Shanglin Yuan Vegetable Department, but now it has gradually been introduced to the people, although it is a little rare, but it can also be eaten. In contrast, he is more curious about how fertilizer is made, and the reason why he is so curious is because he knows the meaning of "manufacturing" in Shi Yiwen's mouth.

"Could it be that fertilizer can be made in factories like everything else?"

looked at Shi Yiwen in surprise, and Xu Sicheng's tone was full of suspicion.

"Well, almost, some ores can be used as fertilizer after simple treatment, and even together with the slag from our sulfuric acid plant, it can also be used to make fertilizer."
