What Professor Zhuang said maybe may become 'certain'. According to the timeline, as the Anti-Japanese War reaches 1940, the relationship between the organization and Nanjing will rapidly deteriorate. With the urinary behavior of Zhongzheng brother and the military commander,
He will definitely find ways to deal with Professor Zhuang Qianding.
This is not alarmist, but fact.
"On the issue of traffic and transportation, please tell me your thoughts." Zhuang Qianding smiled, changed the subject, and asked.
Traffic and transportation are the other two major problems faced by the steelmaking system, and they are very important. Solutions must be thought of in advance and prepared for rainy days.
Zhuang Qianding doesn't like to improvise.
The development of industry is inseparable from a convenient transportation system and means of transportation. Because the base area is located on the Loess Plateau, the road conditions are very poor. Most of them are loess roads, and a few main roads are gravel roads. The road load is low and the road surface is narrow. Two oxcarts can
May cause road congestion.
This kind of road network system is completely unable to bear the astronomical and terrifying flow of raw materials in steelmaking and mines.
Secondly, transportation in the base area is also a big problem. Not to mention heavy-duty trucks and trains, there are only a few tractors. According to the information obtained by Zhuang Qianding, the transportation means for people in northern Shaanxi are horse-drawn carriages, bullock carts, and wheelbarrows.
and legs.
Horse-drawn carriages, bullock carts, and wheelbarrows can transport grain, but they cannot satisfy the huge appetite for various industrial raw materials for steelmaking.
Theoretically, each ton of molten steel smelted by the oxygen top-blown converter process consumes 0.95 tons of molten iron, 150 kilograms of scrap steel, 100 kilograms of limestone and various slagging materials, with a total amount of about 1.4 tons.
Since the blast furnace ironmaking process is far inferior to that of later generations, each ton of pig iron requires 1.9 tons of iron ore, 0.5 tons of coke and 50 kilograms of limestone, while one ton of coking coal can only produce 0.6 tons of coke.
Calculated based on this data, based on the annual output of 35,000 tons of steel, the various industrial raw materials are roughly -
36,750 tons of molten iron,
5,000 tons of scrap steel,
5,000 tons of limestone,
56,000 tons of iron ore,
16,000 tons of coke,
22,000 tons of coking coal.
The total mass of industrial raw materials is as high as 140,000 tons!
Moreover, this is only the industrial raw material demand of steel plants. Sulfuric acid plants and gunpowder plants both require various industrial raw materials needs of thousands of tons and tens of thousands of tons.
It is impossible for the existing transportation tools in the base area to bear such a huge total transportation volume.
If the transportation system and means of transportation cannot be solved, it will be difficult for the base area industry to develop rapidly.
After hearing these two questions, Yu Hua simply sorted out the words and said slowly: "For the transportation system, the students believe that the main road network of Shenmu Mine-Steelmaking Plant and Yikezhao League-Shenmu-Yulin-Yancheng should be established, with cement
Based on the road, multi-stage construction methods are adopted, and a large amount of manpower and material resources are used to establish a prototype of a transportation system in a short time."
Regarding traffic and transportation issues, he had considered it a long time ago, and it was his idea to establish a trunk road network based on cement roads.
"Why not choose the cinder road? The cost of the cinder road is low, and the coke plant and thermal power plant can provide a large amount of cinder every year." Zhuang Qianding thought thoughtfully and nodded lightly. Yu Hua had roughly the same idea as him, but he
I was thinking of using cinder, not cement.
The cost between cement roads and cinder roads, excluding labor and transportation, is that cement roads are only about one-third more expensive than cinder roads.
"First, cinder roads cause a lot of tire wear. In the absence of artificial rubber and the inability to obtain natural rubber supplies, it is better to choose cement roads. Second, cement roads are cost-effective, have long lifespans, are difficult to construct, and are difficult to maintain and resist loads in the future. Performance and other aspects are worse than cinder roads. Although cinder roads are cheaper, their long-term benefits are not as good as cement roads."
Yu Hua gave his own reasons: "Third, we can take this opportunity to establish a cement industry. Cement can be used to build roads, buildings, bridges, and fortifications. Of course, this does not mean that cinders should be completely abandoned. Cement can be used in rural areas and various branch lines.
The roads were paved with cinder blocks.”
Mainly made of cement and supplemented by cinder, this is the basis of the prototype of the transportation system.
In fact, in addition to transportation needs, cement is more useful in the military field.
"Okay, I support this plan. How to solve the transportation problem?"
Professor Zhuang Qianding did not know when he took out the notebook and pen he carried with him and wrote down the transportation system plan given by Yu Hua. After recording, he continued to ask: "I think trucks can be developed, mainly powered by diesel. Gasoline engines are not suitable.
The low temperature environment in northern Shaanxi in winter.”
After saying this, he opened the office door and motioned for Yu Hua to enter.
"Professor, I support your plan, but personally, I feel that developing trucks is a bit too hasty. I think we can build tractors first, accumulate experience, and then build trucks." Yu Hua followed Zhuang Qianding's footsteps and entered the office together, pondering for a while.
Fan, express your inner thoughts.
Building a truck rashly is a bit of a big step. The base area has no foundation and no experience. Whether it can build a truck with up-to-standard performance and reliability and stability is an uncertain factor.
Reliable and stable!
It would be too painful if the manufactured truck stalled after two steps and broke down after one step.
Compared with trucks, tractors appear fresh, refined and practical.
In terms of technical difficulty, reliability and practicality, tractors are much higher than trucks.
The most important thing is that the economic cost and time cost of building a truck can be used to build at least two tractors.
"What you said makes sense. I have somewhat ignored the objective situation of the base area. Regarding the manufacturing level of the base area, building tractors is indeed the best choice." Zhuang Qianding heard this, thoughtfully, and immediately understood that what he was considering was not
Not thorough, he agreed with the plan proposed by Yu Hua, and then said: "What type of tractor should we build?"
This was his problem. He ignored the actual situation in the base area. With the industrial system and machinery manufacturing industry in the base area being almost zero before, it was still very difficult to build power machinery such as trucks.
He can build it. After all, he is a mechanical expert. There is no problem in designing a truck, but whether it is reliable and stable...
have no idea.
The car-building plan has been put on hold for the time being, and the direction has been determined to be tractors. What we have to do now is to conceive of what type of tractor to build.
Tonnage, load weight, engine power, speed.
"The student has an idea." Yu Hua smiled as the walking tractor he had encountered by chance in the countryside appeared in his mind. Then he took out a design drawing, held a pencil in his hand, and quickly drew a concept map.
On the drawing, a concept drawing of a tractor with a unique and aesthetic appearance was quickly presented.
Single-cylinder front drive, panoramic sunroof, independent exhaust, 360-degree panoramic image, multi-angle adjustable seats, heavyweight key, manual shift lever, unrivaled rear space and Mercedes-level trunk baffle, immersive
Chunk, pop, pop, sound, all these elements create an unprecedented power machine - a Chinese classic walking tractor.
