Dongjiadu, as a wharf near the French Concession, is also a relatively large-scale place in Shanghai, and in fact, this industry is closely related to Daotai Huang Zuluo...... However, this can obviously provide a lot of convenience for the silk reeling factory opened by Lu Hong here, Sun Heshun is watching Cheng Daqi and five or six apprentices nervously assembling the machine in the factory near the river at the moment, and at the other end of the factory, an old steam engine obtained from the Jiangnan Manufacturing Bureau is also being debugged.

Lu Hong's mind is obviously not on this freshly baked silk reeling machine, the machine was originally assembled and tested in the factory, except for the steam engine transmission, there should be no problem at all!

According to the news brought by the shipyard assistant, the paint of the hull has been completed, but the reinforcement plan of some of the hull parts proposed by himself, the engineers in the shipyard said that it was difficult to deal with it, and the reason they proposed was very simple, the armor installation method of heating rivets used in this era, once the installation was completed, it was absolutely a time-consuming and laborious thing to remove the large rivets riveted in the red-hot state.

However, after Lu Hong personally took Lu Jianzhang and Qi Fengyi to go around the two battleships, he stopped at a group of gunners who were training at the stern...... For these two rather old battleships, he is also quite helpless, and the only thing that makes him slightly satisfied is the newly installed 120mm rapid-fire gun at the stern, which he spent 10,000 oceans to buy from the back door of the Jiangnan Manufacturing Bureau warehouse in the name of testing, and the overall workmanship is really good.

The barrel is 4.2 meters long, 35 times the diameter of the gun, and the 22 rifling wires of Sensen can be seen on the mouth of the gun barrel, showing the technical level of the Jiangnan Manufacturing Bureau in the artillery boring, the whole gun weighs 2.1 tons, and the standard Krupp bottom sleeve technology is used to ensure the safety of the artillery.

For Lu Hong, the 35 times the diameter of the 120mm gun is indeed not a superb weapon, Xiao said that the 120mm rapid-fire gun on the Yoshino has long been 40 times the diameter, however, considering the premise of the Jiangnan Manufacturing Bureau's self-production, after all, it can be mass-produced, which is also within the acceptable range, but the efficiency of the Jiangnan Manufacturing Bureau Gun Factory really made him embarrassed for a while.

At the beginning of 1893, the process of the 120mm rapid-fire gun had been completed with the introduction of Krupp machines and the training of technicians, but for a whole year, when he mentioned the gun to Ruisheng earlier, he said with an embarrassed face that the entire artillery bureau had only produced 12 guns a year...... And 6 of them have been ...... by Li Hanzhang, the governor of Liangguang That is, Li Jingxiang's old man, Li Hongzhang and his eldest brother have placed an order, but the silver has not been paid yet, so it is still in the warehouse for the time being.

The other 1 was delivered to Beiyang for testing a year ago, but the Minister of Beiyang, Li Hongzhang, has not placed an order so far, so this is the backdoor transaction that Lu Hong spent 20,000 yuan to buy the right to use first, and the other three guns are still in the artillery bureau, Ruisheng is also willing to sell them to Lu Hong, however, Lu Hong's silver is also very tight, although there is a large investment, but it is to build a factory and produce benefits, otherwise there will be a big head to invest money in himself in the future!

After Lu Hong's proposal for this artillery to increase the simple round handle high and low machine customized by Lu Hong, the entire gun carriage increased by 0.2 tons, but it was only 2.7 tons, in addition, on the gun mount, a vertical pendulum was added as a simple indicator to show the horizontal position of the pitch, and for this overall transformation, Lu Hong was very satisfied.

According to the "continuous aiming artillery technique" taught by Qin Kai, Lu Jianzhang has trained 10 grassroots soldiers of the artillery group, of course, because the two ships Nanrui and Nanchen are now painting on the slipway, their training can only be simulated with training shells, however, for the effectiveness of this artillery technique, in fact, Lu Jianzhang and Qi Fengyi, who are temporary teachers, are not very sure.

Lu Hong watched several groups of soldiers reload in a decent manner, constantly shaking the high and low machines up and down, left and right according to the instructions, and pushing the turntable...... In fact, this manual turntable is very different from the direction machine of later generations, and Lu Hong has also thought about transforming this thing, but this involves a major change in the entire gun mount, and it is really impossible to do it all at once, but fortunately, the left and right rotation is also flexible, although there is no accurate scale marking, it can be used.

He turned his head and nodded at Lu Jianzhang, "Jianzhang, this training is good, when the ship is repaired as a whole, pull it out and practice live ammunition well...... Cannonballs, I'll go to Ruisheng to get some, I can't improve this artillery skill without practicing with real guns! ”

"My lord, these brothers we brought here are all good soldiers in the water division, and they practice from morning to night every day, and there is absolutely no laziness...... You can rest assured, in most of you, you will definitely be able to practice this new artillery skill! Lu Jianzhang grinned loudly and replied.

He and Qi Fengyi both had an expression of awe on their faces, Lu Hong said that this continuous aiming artillery technique was amazing, and the two of them still had some doubts in their hearts, but they were proficient in the principles of artillery skills, and they naturally understood the key essence of this artillery technique, although they were not sure what effect Lu Hong's approach could achieve, but this was definitely a major improvement in artillery skills, and for Lu Hong, who could make up this new artillery technique, he also admired it from the bottom of his heart.

Lu Hong nodded, this progress in artillery technology can naturally greatly improve the combat effectiveness, although the tube retreat technology used in the rapid-fire cannon made by the Jiangnan Manufacturing Bureau today is actually still relatively outdated water suppression retreat device, but ...... Even so, due to the use of a copper-shelled ammunition, Lu Jianzhang's gunner training has been able to achieve a good efficiency of 4 rounds per minute during training.

However, the weaknesses of the two ships of Nanrui and Nanchen are actually very clearly laid out in front of them, after all, they are old ships 10 years ago, and he pointed out the weaknesses of these two warships very directly in front of Lu Jianzhang and Qi Fengyi...... At best, it is an iron-hulled battleship, and in terms of protection, 1 inch of wrought iron armor, the most equipped Haqikes 37mm cannon on the battleship of this era can penetrate at a distance of 1000 meters, not to mention the 120mm and 150mm rapid-fire guns.

Lu Hong naturally wanted to let these two agents who he temporarily found to figure out the situation, but fortunately, Lu Jianzhang and Qi Fengyi have also done teaching, and the communication in this regard is completely barrier-free, and he also deeply sympathizes with the current situation of the Nanyang Naval Division.

Next, Lu Hong took a few engineers to inspect all the way to get the situation together, it was even more shocking, the long-term maintenance was not in place, the original two warships in the 4 circular horizontal fire-tube boilers carbon sintering is serious, the entire water-tube boiler furnace and boiler steam pressure is only 7% of the original state, which also means that now it is difficult for Nanrui and Nanchen to run more than 12 knots!

Subsequently, after Lu Hong found more than a dozen old engineers in the shipyard, he specially asked about the possible surname of the boiler transformation, but the answer he got made him very depressed, and Nanrui and Nanchen did not have the possible surname of the boiler, but this work in the Jiangnan Shipyard could not be done...... There is simply no experience and ability to disassemble armored ships on this side.
