Release that Witch Chapter 657: The Secret of the Two

...

Roland made a cup of tea for himself, then looked at Nightingale, "You either?"

"Yes, thank you."

She leaned on the reclining chair, holding dried fish in one hand, and holding a new script written by May in one hand, which was very interesting.

Since Anna talked to her, Nightingale first disappeared for two days, and when she appeared in front of Roland again, she seemed to be relieved of her burden and returned to her former freedom. There was always a masked smile on his face, and occasionally he looked at him secretly, his eyes full of vitality.

Like she is now.

Put your feet horizontally on the coffee table without hesitation, robe rolled to the side, exposing the slender legs wrapped in black stockings. Only when someone is come in will you hide your body briefly. This seductive pose often caused Roland's eyes to shift to one side involuntarily, causing half a morning to pass without even drawing a drawing.

I did n’t know that I would n’t ask Soraya to draw this kind of nylon qualitative thermal socks.

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

She put down the script, both hands took it, and sniffed hard, "Ah ... It's so fragrant, can you help me add some sugar? "

In future generations, Nightingale is undoubtedly a centrist from both parties, and it does n’t matter how fat it is. During the period of Roland falling asleep, she lost a lot of weight, and she lost a lot of weight all over her body, but quickly recovered to normal level after he woke up, and the weight seemed to have an upper limit, reaching this After the standard, it will never grow again.

In the past, Roland would still say two words to eat too much and easily get fat, but now I find that the other party does not need to worry about this at all.

Putting a piece of sugar into her tea cup, he returned to the table and drew a few more strokes. Eventually, he couldn't help curiosity, and said, "Nightingale ..."

"Yeah?"

"Anna she ... what did she say to you?"

"Well ..." She blinked and appeared steadily on the desk. "It's a secret."

"Can't I even tell?"

"It was required by Anna," Nightingale hesitated, and finally shook his head. "If it's about me, I'll say anything you want to know, but this ... she keeps me secret."

"Well, okay," Roland drank his tea, and didn't keep asking. Although he can go directly to Anna, people with normal emotional quotient will not repeatedly mention it at this time.

At least he can see that Anna is not angry about it.

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

"What?" Roland froze for a moment, raised head, right in front of her eyes.

Qiu Yang dyed her long golden hair, and also left a bright light spot on her face. The moving face was as beautiful as a picture scroll in the warm sunlight, and time seemed to stop because of it.

"Thank you for telling her my wish."

...

By the afternoon, good news came from Ministry of Construction. According to the new drawing of the steel-making facilities drawn by Roland, the first converter steel-making plant fell to the foot of Northern Slope Mountain.

Of course, it ’s a factory, it looks more like a simple iron shed, and there is a new large-scale equipment alone. It is different from all previous furnace. The smelting equipment is all over the body. It is made of steel. The angular furnace frame and the huge converter have been coated with heat-resistant coating. The gray-black matte surface gives a majestic and heavy feeling in the sun.

When Roland brought City Hall officials to the furnace area, the old workers who had been recruited for the new stove were surrounded by leaks. Obviously everyone was curious about it.

"Your Majesty, can this furnace really make steel? It doesn't even have a place to burn fire." Although Ministry of Construction's Lowes had previously questioned this problem, he still meticulously completed the converter according to the requirements on the map All the components for building it were made by Anna, and the weight reduction assembly of Hummingbird shortened the construction period to less than one week.

"It is not only the flame that generates heat in nature," Roland laughed, "let the workers prepare for the furnace trials."

The three main technologies of steelmaking are open hearth furnace, converter furnace and electric furnace. The electric furnaces that are not yet qualified are first eliminated. The remaining two have chosen the latter after considering a long time.

The open hearth furnace is the simplest in structure and closer to the traditional furnace, but the disadvantages are also very obvious. First of all, it requires a lot of fuel, which is very unfavorable for the available natural resource of Neverwinter City. After all, coal mines are far from the source of Scarlet Water River, and Coking Factory has just begun. It is already struggling to meet the needs of blast furnace iron smelting. Adding an open-hearth steelmaking will cause fuel shortage.

This is also the biggest advantage of the converter, which requires almost no fuel consumption. It oxidizes itself by oxidizing impurities such as manganese, silicon, and carbon in pig iron, so that the temperature of molten iron is always maintained at a high point, so that the smelting reaction continues.

The second disadvantage of the open hearth furnace is that it occupies a large area and has a long smelting time. In order to enhance the use of fuel, the open furnace needs to build a heat storage pool, preheat the air in advance, and it takes more than half a day to make a furnace of molten steel. . In the case of a converter, the size of the furnace is the volume of the equipment. The track and the molten steel transportation system can be shared. It only takes tens of minutes to smelt at one time. After the technology is mature, it can be shortened to less than a quarter of an hour. The efficiency varies greatly.

In view of these two points, Roland chose to use the converter as the main steelmaking equipment for Neverwinter City in the future.

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

"Anna, let's make a fire."

Anna nodded and walked down the stairs to the top of the converter, summoning the black fire to melt the iron ingots. After a while, the hot red iron in the furnace reflected her face.

When the production is started, the molten iron will be provided by the blast furnace, which is why he built the steel plant in the furnace area.

"Now follow the steps I said," Roland instructed the person in charge of the steelmaking group, "Plug the blowpipe into the furnace mouth."

Although it is the first time that these selected veteran workers have officially contacted converter steelmaking, they have already operated similar subsystems before. There is no essential difference between manipulating pipes and controlling trailers. steam engine rumbling, 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 and leads to the exhaust equipment driven by steam engine. As the oxygen-enriched air is drawn into the converter, the furnace mouth suddenly bursts into the sky, and orange sparks splash out of the furnace. Like a firework blooming. The dazzling light shows a strange incandescent, almost impossible to look directly.

This spectacular scene surprised the City Hall officials.

Roland felt extremely satisfied in the scorching hot waves coming from his face.

These sparks are a symbol of humanity's progress towards a new era.
