Chapter 657 The Secret of the Two

...

Roland made himself a cup of tea, then looked at Nightingale, "Do you want to?"

"Yes, thank you."

She was leaning on the recliner, holding the dried fish in one hand, and a new script written by May in the other, reading it with gusto.

After Anna talked with her, Nightingale disappeared for two days, and when she reappeared in front of Roland, she seemed to have unloaded a burden and returned to her previous free appearance. There is always a smile that cannot be concealed on his face, and occasionally he will sneak a few glances at him, his eyes are full of vitality.

Just like she is now.

He unscrupulously put his feet horizontally on the coffee table, and pulled his robe to the side, revealing his slender legs wrapped in black stockings. He would only hide his figure for a short time when someone came in. This seductive posture made Roland's eyes often turn to one side involuntarily. As a result, half the morning passed without even drawing a blueprint.

If I had known earlier, I would not have asked Soraya to draw such warm socks that were made of nylon.

He brought another cup of tea with a pleasant fragrance to Nightingale, "The tea you want."

She put down the script, took it with both hands, and sniffed it vigorously, "Ah...it smells so good, can you add another piece of sugar for me?"

In future generations, Nightingale is undoubtedly a centrist of the sweet and salty parties, and she can't get fat no matter what she eats. During the time when Roland was unconscious, she lost a lot of weight, and she lost a lot of weight all over her body, but after he woke up, she quickly returned to normal levels, and there seemed to be an upper limit to her weight. After the standard, it will never grow again.

In the past, Roland would chatter about eating too much and getting fat easily, but now he realizes that the other party doesn't need to worry about this at all.

Putting a piece of sugar into her teacup, he went back to the table and drew a few more strokes. Finally, he couldn't help his curiosity and said, "Nightingale..."

"Um?"

"Anna...what did she tell you?"

"Well..." She suddenly appeared on the desk, "It's a secret."

"Can't even I tell?"

"Anna asked for it." Nightingale hesitated for a moment, and finally shook her head. "If it's about me, I'll tell you anything you want to know, but this...she asked me to keep it a secret for now."

"Well, okay," Roland took a sip of tea, and did not continue to ask questions. Although he could go directly to Anna, no one with a normal EQ would mention this matter repeatedly at such a time.

At least he could see that Anna was not annoyed by this.

Just when he picked up the quill again, Nightingale suddenly said, "Thank you."

"What?" Roland froze for a moment, raised his head, and met her eyes.

Qiuyang dyed her long golden hair brightly, and also left bright spots on her face. Under the warm sunshine, her charming face was as beautiful as a picture scroll, and time seemed to stop because of it.

"Thank you for telling her my wish."

...

In the afternoon, good news came from the Ministry of Construction. According to Roland's new drawings of steelmaking facilities, the first converter steelmaking plant was completed at the foot of the North Slope.

Of course, if it is a factory, it looks more like a simple iron shed, and a large-scale new equipment is placed alone in it—different from all previous furnaces, this time the smelting equipment is covered with It is made of steel. The sharp-edged furnace frame and the huge converter have been coated with heat-resistant coating. The gray-black matte surface gives people a sense of majesty and thickness in the sun.

When Roland brought the city hall officials to the kiln area, the new stove had been surrounded by recruited old workers, obviously everyone was full of curiosity about it.

"Your Majesty, can this furnace really make steel? It doesn't even have a place to burn fire." Although Luo Siya from the Ministry of Construction had questioned this question before, he still completed the construction of the converter meticulously according to the requirements on the diagram ——Its components are all made by Anna, and the weight-reducing assembly of Hummingbird shortens the construction period to less than one week.

"Flames are not the only ones that generate heat in nature," Roland said with a smile, "Let the workers get ready for the furnace trial."

The three main technologies for steelmaking are open hearth furnace, converter and electric furnace. Electric furnaces that are not ready for the conditions are excluded first, and he chose the latter after a long consideration of the remaining two.

Although the open hearth furnace is the simplest in structure and its operation is closer to that of a traditional furnace, its disadvantages are also very obvious - first of all, it requires a lot of fuel, which is very unfavorable for the available resources of Neverwinter. After all, the coal mine is far away at the source of the Chishui River, and the coking plant has just started. It is already very difficult to meet the needs of the blast furnace for iron smelting. If an open hearth furnace is added to make steel, it will lead to a shortage of fuel.

And this is the biggest advantage of the converter - almost no fuel consumption. It releases heat by itself through the oxidation of manganese, silicon, carbon and other impurities in pig iron, so that the temperature of molten iron is always maintained at a high point, so that the smelting reaction continues continuously.

The second disadvantage of the open hearth furnace is that it occupies a large area and takes a long time to smelt. In order to enhance the utilization of fuel, the open hearth furnace needs to build a heat storage pool and preheat the air in advance. It takes more than half a day to smelt a furnace of molten steel. If it is replaced by a converter, the size of the furnace is equal to the volume of the equipment, and the track and molten steel transportation system can be shared. It only takes tens of minutes to smelt once, and it can even be shortened to less than a quarter of an hour when the technology matures. The efficiency varies greatly.

It is precisely because of these two points that Roland chose to use the converter as the main steelmaking equipment in Neverwinter City in the future.

With the help of the steam engine, the workers quickly dumped a large pile of pig iron ingots into the pear-shaped furnace.

"Anna, light a fire."

Anna nodded, followed the stairs to the top of the converter, and summoned the black fire to melt the iron ingots. After a while, the red hot molten iron in the furnace shone brightly on her face.

When it comes to official production, the molten iron in the steelmaking plant will be provided by the blast furnace, which is why he built the steel plant in the kiln area.

"Next, follow the steps I said," Roland instructed the person in charge of the steelmaking team, "insert the blowing pipe into the furnace mouth."

Although these selected old workers are officially exposed to converter steelmaking for the first time, they have already operated similar subsystems before, and there is no essential difference between manipulating pipelines and controlling trailers. The steam engine rumbled, and a steel pipe slowly fell from the furnace roof into the chamber.

The other end of the steel pipe is connected to the coated hose, leading to the exhaust equipment driven by the steam engine. As the oxygen-enriched air is sucked into the converter, the furnace mouth bursts into flames, and orange-red sparks splash out from the furnace, like blooming fireworks. The dazzling light was so strangely incandescent that it was almost impossible to look directly at it.

The spectacular scene amazed city hall officials.

Facing the scorching air waves rushing towards his face, Roland felt extremely satisfied in his heart.

These sparks are the symbol of mankind entering a new era.
