Release that Witch

657. Chapter 657 Secrets of the two

……

    Roland made himself a cup of tea and then looked at Nightingale. “Are you either?”

    “Yes, thank you.”

    She leaned on the lounge chair, holding dried fish in one hand, and holding a newly written script from May, and she was very interested.

    Since Anna talked to her, Nightingale disappeared for two days. When she appeared again in front of Roland, she seemed to have unloaded the burden and changed back to her former freedom. There is always a smile that can’t be concealed on his face, and occasionally he will sneak a few eyes on him, his eyes full of energy.

    Just like she is now.

    Unscrupulously, the feet are placed on the coffee table, and the robes are smashed to the side, revealing the slender legs wrapped in black stockings. Only when someone comes in, will they temporarily hide their bodies. This tempting posture made Roland’s eyes often involuntarily sideways, causing half a morning to pass, and even a pair of drawings have not been drawn.

    I knew that it wasn’t called Soraya to draw this kind of qualitative warm socks close to nylon.

    He brought another cup of tea with a pleasant fragrance to the front of Nightingale, “The tea you want.”

    She put down the script, and the both hands took it and sniffed, “ah…Good fragrance, can you help me add a piece of sugar? ”

    In the afterlife, Nightingale is undoubtedly a middle-sex person of the salty and sweet parties, and how can they not eat fat. During Roland’s sleepy time, she lost weight very seriously, and she lost weight in her body, but when she woke up, she quickly returned to normal level, and the weight seemed to have an upper limit. After the standard, it will never grow again.

    In the past, Roland would eat too much and easily get fat. Now I realize that the other party does not have to worry about this.

    Putting a piece of sugar into her cup, he went back to the table and drew a few more. Finally, he couldn’t help but curiosity and said, “Nightingale…”

    “Yeah?”

    “Anna she…What did you say to you? ”

    WellShe flashed and appeared on the desk steadily. “It’s a secret.”

    “Can’t I even tell?”

    “It was Anna’s request,” Nightingale hesitated, and finally shook his head. “If it’s about me, you want to know what I will say, but this…She kept me secret for the time being. ”

    “Oh, okay,” Roland drank the tea and didn’t continue to ask. Although he can go directly to Anna, people with normal emotional intelligence will not repeatedly mention this matter at this time.

    At least he can see that Anna is not angry at this.

    Just when he mentioned the quill again, Nightingale suddenly said, “Thank you.”

    “What?”Roland groaned, raised head, just in time with her eyes.

    Qiuyang dyed her long blond hair and left a bright spot on her face. The moving face was beautiful in the warm sunshine, and the time seemed to stop.

    “Thank you for telling her my wish.”

……

    In the afternoon, the Ministry of Construction sent good news. According to Roland’s newly drawn steelmaking facility drawings, the first converter steel plant fell on the foot of Northern Slope Mountain.

    Of course, it is a factory, it looks more like a simple iron shed, with a new piece of equipment on its own scale – unlike all previous furniture, this smelting equipment is all over the body. Cast from steel, the angular grid and the large converter have been coated with a heat-resistant coating, and the matte surface of the gray-black color gives a heavy feeling in the sun.

    When Roland came to the Furnace district with City Hall officials, the old workers who had been recruited by the new stoves were surrounded by water. Obviously everyone was curious about it.

    “Your Majesty, can this stove really make steel? It doesn’t even have a place to burn. ”Although Lowes of Ministry of Construction had questioned this question before, he still completed the converter construction in accordance with the requirements of the figure – its components were all made by Anna, and the weight-reduction assembly of Hummingbird allowed the construction period. Shortened to a week.

    “It’s not just the flames that generate heat in nature,” Roland laughs. “Let the workers prepare for the trial.”

    The three main technologies of steelmaking are open hearth, converter and electric furnace. The electric furnace that is not yet qualified is first excluded. The remaining two he chose the latter after considering it for a long time.

    Although the flat furnace is the simplest in structure and operates closer to conventional furnaces, the disadvantages are equally obvious – first of all, it requires a lot of fuel, which is very unfavorable for Neverwinter City’s available natural resources. After all, the coal mine is far from the source of the Scarlet Water River, and the Coking Factory is just getting started. It is already very difficult to meet the needs of blast furnace iron, and adding a flat furnace steel can cause fuel to be stretched.

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

    The second disadvantage of the open hearth is that it covers a large area and has a long smelting time. In order to strengthen the use of fuel, the open hearth needs to build a heat storage tank, preheating the air in advance, and it takes a long time to refine a furnace of steel. When changing to a converter, the size of the furnace is the size of the equipment. The track and the steel water transportation system can be shared. The smelting takes only tens of minutes, and even after the technology is mature, it can be shortened within 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 of Neverwinter City in the future.

    With the help of the Steam engine, the workers quickly dumped a pile of pig iron ingots into a pear-shaped hearth.

    “Anna, let’s make a fire.”

    Anna nodded and climbed up the top of the converter along the stairs, summoning a black fire melting iron ingot, and in a moment, the hot red iron in the furnace brightened her face.

    When the production is officially produced, the molten iron from the steel mill will be supplied by the blast furnace, which is why he built the steel plant in the furnace area.

    “Follow the steps I said,” Roland told the head of the steelmaking team, “Insert the blowpipe into the mouth of the furnace.”

    Although these selected old workers were the first to formally contact with converter steelmaking, they have already operated similar subsystems before, and there is no essential difference between manipulating the pipeline and controlling the trailer. The steam engine rumbling, and a steel pipe slowly fell from the top of the furnace into the raft.

    The other end of the steel pipe is connected to the coating hose and leads to the steam engine-driven pumping equipment. As the oxygen-enriched air is sucked into the converter, the furnace suddenly bursts into the flames, and the orange-red sparks splash out of the furnace. Blooming fireworks. The dazzling light presents a strange incandescent, almost impossible to look directly at.

    This spectacular scene surprised City Hall officials.

    Roland felt the unparalleled satisfaction in the burning waves of the face.

    These sparks are the symbol of humanity’s march towards a new era.
