Release that Witch

"Hey..." Hillview looked at the shells for a while, and looked at Roland's design sketch for a long time before pointing to the detonator. "It seems that this copper tube is not aligned with the top nail."

"What about springs?" Anna asked. "Is it stuck on both sides of the iron plate?"

"There is a cockroach."

"Left or right?"

Anna asked for the details and then recorded the questions one by one on the book.

After collecting the reasons for the failure, it is the next round of shooting - four shots can just use Asha's playback ability, so that the efficiency of improvement has naturally become unprecedented.

Unfortunately, the next two rounds of test firing also failed, and Roland had to announce that he would continue the test tomorrow.

For Asha and Sylvie, they have all finished their work today. After that, they can go back to the castle to enjoy a delicious afternoon tea, or go to the convenience market to see if there are any novelty items. But for Anna and Ai Gesha, the grenade test is just a small part of the busy work. In particular, Anna, in addition to improving the fuze in accordance with the reasons for failure, she had to complete the development and assembly of the steam turbine.

Luo Lan intended to follow her to the backyard of the North Slope to see the progress of the turbine model, and the guardian Sean brought the news of the city hall.

"His Majesty, Deputy Minister of Construction Luo Yaya hopes that you can go to the furnace area, he said that the first dry distillation furnace has been set up."

......

As a necessary facility for the coking plant, the planned ten dry distillation towers are located beside the kiln group at the foot of the northern **** mining area.

Due to the large-scale felling of bricks and iron-making, the kiln group has changed from a small plot of less than 1,000 square meters at the beginning to a broad gap extending along the mountain. If it is not Roland that prohibits workers from accessing the woods near the town, it is estimated that there will not be a tree in the north of the border area.

Nowadays, although there is coal, the convenient and easy-to-obtain charcoal is still the main force of iron smelting. As the tree-removing site is farther away from the kiln group, the workers will aim at the north **** mountain - there will be hundreds of pieces every day. The logs were cut off and then dropped from the top of the mountain. From a distance, a small piece of "bald spot" appeared in the green mountain peaks.

Roland naturally does not ask them to protect the environment in this kind of thing. As long as the dust does not affect the town, he does not care if he cuts down the North Hill. After all, compared to the desperate mountains, this prominent small mountain range is just a negligible corner. There are leaves to maintain the basic vegetation, and there is basically no need to worry about soil erosion.

The flat land that was opened at the foot of the mountain naturally became the most suitable place for the coking plant.

Roland walked through the noisy kiln area with the nightingale and guards to the front of the first retort. Luo Ya immediately greeted him and bowed to him. "Your Majesty, I built this double-layer kiln with refractory bricks according to your requirements. According to the drawings, the upper furnace should be closed with iron gates, the middle mezzanine There are also iron plates that can be moved freely, but I don't know who to look for to make these two things. In addition, the copper pipes and chimneys on the small stove are also finished, except for these metal components.

Roland went into the oven and checked it all over. I have to say that as a member of the original stonemason, Carl Vabert's old friend, Losya really had a lot of experience in the masonry. The inner wall of the nearly two-storey dry distillation tower is evenly changed. The gap between each brick is basically the same. The brick joints are also layered and interlaced, and there is no straight seam. It is obvious that not only the layout ability is extraordinary, but also the construction attitude is very serious. . It is important to know that even if you use the same drawing, the finished products built by different people may be very different.

"Good job," he applauded after checking. "I will arrange for the iron gate and the iron plate to be cast. Then you only use the fire-resistant brick on its fire surface."

"Your Majesty," Losya said with hesitation. "Can you tell me how this stove works?"

"Why, do you want to be a coking worker?" Roland joked.

"Of course not," the other party shook his head. "I have never built such a strange kiln before, so the description on the drawing is not known. I can only rely on guessing. If you can know its specific usage and function, build it. The second seat can not only be completed faster, but I can also improve some places where I can't handle it."

So, Roland laughed. "This type of kiln is mainly used for dry distillation of coal. How should you see how charcoal is burned? This is similar, but the scale is bigger. The lower layer burns, the upper layer is baked, the filler It's all coal."

“Boiled coal with coal?” Losya surprised.

“Yes, after the carbon has been retorted, it can be converted into coke and burned at a higher temperature. It is a good fuel for steelmaking. In addition, several by-products are produced during the retorting process, and the pipes on the tower wall are used. Collect them, not the exhaust chimney."

"That... Why is there a small stove built on the side of the stove?

“There should be no air left in the upper layer during retorting, otherwise the coal will burn directly,” Roland pointed to the hole reserved in the two furnaces. “The calcined limestone in the small furnace will produce a lot of carbon dioxide – you can understand that it cannot burn. gas……"

"Your Majesty, I know this," Losya said. "There is a teaching in the evening class."

"That's simple," Rolandton said. It seems that the popularization education work is expanding the content a little bit under the efforts of the book. "Carbon dioxide will enter the upper layer of the kiln through the pipeline, and all the air will be discharged, so that the coal can achieve the dry distillation effect. As for limestone, it is the gray-white stone used to burn cement. The northern slopes are everywhere."

......

After inspecting the first tower of dry distillation and returning along the original road, he stayed by the kiln area for a while.

Looking at the busy scene in front of me, Roland’s heart was a little bit stirring. A variety of brick furnaces stand side by side. At first glance, it looks like a neat red forest. There are dozens of columns of smoke rising above the forest. The gray, white and black are intertwined with the plain workers. The backward appliances together constitute a very contemporary image. More than a dozen steam engines are rumbling, pulling the conveyor belt to send pieces of raw materials and charcoal into the blast furnace; the track system is also laid from the mine hole, and a small mine car runs through the two places. In the meantime, the speed of iron ore transfer has long been different.

After the completion of the construction of the steel mill and the forging plant, this place will inevitably become another core place for the winter city - from ore mining to smelting into steel, and then converting the steel into various raw materials and sending it to the processing plant. Born here, it has given human strength and extraordinary strength, and they have the courage to overcome everything.
