Lin Yuan continued: "The reason for the demise of the battleship is very clear to everyone, as for the reason for the demise of the cruiser, after the warship was widely equipped with radar and missiles, the cruiser's original long-distance reconnaissance and jamming mission has been replaced, the function of the cruiser and the destroyer are almost the same, and the weapons equipped are also similar, the only difference is whether to load more or less." ”

"So in our time, except for the United States and Russia, which are equipped with Ticonderoga-class and Glorious-class missile cruisers, there are no other countries equipped with cruisers, and the cruisers equipped by these two countries are also going to be decommissioned, and there is no follow-up plan to build ships."

"Therefore, the main warship of our navy, the displacement is not too large, a full load displacement of 7,000 tons is enough, you don't have to worry about insufficient firepower, this tonnage is enough to hold more than 30 missiles with a charge of 300 kilograms, such missiles, three to four are enough to sink a 30,000-ton battleship, and one of our battleships can fight against an enemy fleet!"

Lin Yuan said: "According to our current situation, the Japanese and Russians are most likely to attack from the sea, in order to deal with the possible war, we will build four or five destroyers first, and we will build other military ships, such as submarines and large landing ships, later." Lin Yuan looked at Wan Ling as he said and asked, "Elder Wan, is there any difficulty in the shipyard now?" ”

Wan Ling said: "This is not easy to explain here, so let's go to the shipyard after the meeting, and we will talk about it there." ”

Lin Yuan nodded and said, "Okay, let's stop today's meeting, Wan Lao, let's go to the shipyard together." Lin Yuan announced the dismissal of the meeting, and then came to the shipyard, the shipyard is located near the Lushun Military Port, and the naval base of Lushun is far away, far away Lin Yuan saw a large factory building erected on the seaside, Wan Ling pointed to those factories and introduced: "Those are the design center, those are the processing workshop......

Wan Ling pointed to a tall chimney and said, "See? That chimney was used for the boiler of the power plant, and the shipyard now has a very good supply of electricity. After Wan Ling finished speaking, he pointed to the railroad tracks on the ground and said, "We still have railroad tracks here, and the raw materials outside the factory can be easily transported in." ”

Wan Ling said and walked along the steel rails to the inside of the workshop, and said to Lin Yuan as he walked: "In fact, building a warship is also very simple, that is, use steel to build the skeleton of the hull, and then install weapons on it, the difficulty is how to build and how to install it." ”

Wan Ling said and took Lin Yuan into a spacious workshop, where a large number of steel were stacked, the shape of these steels was different, some were round bar shaped, some were I-shaped, and some were plate-shaped, Wan Ling said: "This is where we store the raw materials to be processed, some of them are steel, some are aluminum alloys, and there are other alloys such as tin bronze, these alloys need to be cut and welded to become the components needed for the battleship, and they have to go through several processes before cutting and welding, These processes are collectively referred to as the pretreatment of steel. ”

Wan Ling said and pointed to the door in the distance, where the railroad tracks came out, and he said, "There is the steel pretreatment plant." Wan Ling said and took Lin Yuan to walk over there, and said as he walked: "Those stacks of steel look very straight, in fact, it is just that the resolution of the human eye is not enough, and they can't see their bending, and those steels are no longer straight due to uneven heating during casting, or when they are stored under temperature stress, so our first step is to straighten them, which is called 'correction'." ”

At this time, the two came to the outside of the factory, and as soon as they came in, Lin Yuan saw a wide conveyor belt, Wan Ling pointed to the conveyor belt and said: "There is a transport car on the railroad track, and the transport vehicle sends the steel from the storage room here, and there is a crane on the beam of the house, pick up the steel and put it on the conveyor belt, and the conveyor belt sends the steel that needs to be corrected into the straightening machine." ”

Lin Yuan saw a huge machine at one end of the conveyor belt, with two rows of sticks in it, Lin Yuan pointed to the machine and asked, "That is the correction machine?" Right? ”

Wan Ling nodded and said, "That's right, that's the straightening machine, the upper and lower rows are rolls, the extrusion of the rolls makes the uneven steel straight, and the steel enters the next machine after the leveler." As he spoke, he walked past the straightening machine, along the conveyor belt to an even larger machine, patted it with his hand, and said, "Shot blasting machine." ”

"After the steel is placed in the air for a period of time, there will be an oxide layer on the surface, if the oxide layer is not removed, it will reduce the fatigue strength of the steel and shorten the life of the hull, so we remove the oxide layer on the surface, and this shot blasting and rust removal machine is used, this machine can spray out the small iron balls at high speed, hit the steel, remove the oxide layer on the surface, remove the oxide layer, and then apply a layer of primer, you can officially cut, and after cutting, you can weld into the required parts, and our problem, Happened to appear at this time. ”

Lin Yuan asked, "What's the problem?" ”

Wan Ling said and picked up a drawing from the cabinet next to him, pointed at it and said to Lin Yuan: "Look at this drawing, it is a drawing of the ribs of the hull, the ratio is one to fifty, when processing, this drawing should be converted into a one-to-one drawing, so that our workers can process the required shape on the steel, we call the process of drawing conversion lofting, do you think this lofting process is difficult?" ”

Lin Yuan thought for a while and said: "I think the difficulty should not be small, I see that the parts on the drawing are composed of curves and surfaces, which is difficult for workers to ensure that the curvature of the converted curve is the same as the original curve when converting the proportion, am I right?" ”

Wan Ling said: "Yes, in our time, there are computer-controlled fully automatic equipment, which can achieve mathematical lofting, and the accuracy is much higher than that of manual ones, but in this era, we do not have such equipment, so we can only rely on manpower to complete this step." ”

"Not only this step, but also the drawings after the lofting is completed, and the final warship parts need to fall from the drawings to the real thing, so we need the next step, drawing a cutting line on the steel, and we call this process the number material."

Lin Yuan asked, "Both processes require manpower, don't they?" What we're lacking is skilled technicians, right? ”

Wan Ling nodded, and Lin Yuan asked, "Then we don't have such skilled workers now?" ”

Wan Ling replied: "There are a few old engineers on the Beijing ship who used to work as lofting number workers in the shipyard, but the number of them is too small, and if we want to build a warship on a large scale, we can't do it without a large number of skilled technical workers." ”

Lin Yuan thought for a while and said: "It's definitely too late for us to train ourselves, so we will gather all the domestic talents, first of all, the Jiangnan Shipyard, which is a more famous shipyard, and the Fuzhou Shipbuilding Bureau, that is, the Mawei Shipyard, we will go there and get all the talents inside." ”

Wan Ling asked, "But what can you do to get them?" ”

Lin Yuan replied: "Jiangnan Shipyard, there is no problem, I have a good relationship with Li Hongzhang, and Li Hongzhang also entrusted me to build a navy when he was dying, so Jiangnan Shipyard is basically under my control, and the Fuzhou Shipbuilding Bureau will require me to work hard." ”
