Anti-Japanese blood sacrifice mountains and rivers

Gao Fei secretly developed a new type of tank armor. Tank armor is crucial to the survivability of tanks on the battlefield. While the Americans helped Gao Fei build a naval base in Lushun, Huludao Shipyard and Dalian Shipyard have entered the later stage. During the installation stage, the [-]-ton hydraulic press was shipped from the United States to China for assembly. In particular, the Chinese shipyard in Dalian was designed by the Americans to build a fleet-class aircraft carrier. Gao Fei rejected the American battleship Iowa. Class docks, but chose the latest Washington-class cruiser docks. Future battleships will withdraw from the stage of history with the decisive battle of the aircraft carrier fleet, but guided missile cruisers, frigates, and multi-purpose destroyers will enter the stage of war with the development of science and technology. For those who do not have For the necessary outdated weapon systems, Gao Fei does not recommend spending materials to build them. %&*";

Tank armor and ship armor have a common commonality, but obviously the cost of tank armor is relatively high. After Gao Fei’s reminder, the Armor Research Institute believes that another way to improve armor protection is to change the material. Refer to the British According to the information obtained by German scientific researchers in the naval equipment research department, a steel called KCN2FA is used on the protective steel plates used by German battleships. The scientific name of this steel is nickel-chromium-manganese alloy surface carburizing hardened steel. 670700hb, the decreasing carburizing depth is 40.00% to 230240%, the hardness of the base material is 130hb, its protective effect can reach the equivalent of [-]% thickness of ordinary uniform steel, the protection principle of quenched armor is through the high hardness of the surface layer to shatter incoming projectiles.

But for Gao Fei, the armor system applied by the Germans on the Tiger tank and King Tiger tank is completely behind. For the ever-changing anti-tank weapons, Gao Fei believes that high-quality rolled steel armor and alloy steel armor It is the mainstream. The armor structure has also developed to be mainly welded armor and integral cast armor. Riveted armor is destined to withdraw from the stage of history. The actual combat also proves that the cheap riveted armor that the Japanese have been holding on to has been beaten to pieces. fact. .cc|

The emergence of hollow-charge ammunition being developed by the United States and the Soviet Union has made tank armor face severe challenges. The United States produced a large number of m4 tanks in World War II, and achieved good results by using cast armor steel technology, but Gao Fei decided that it must adopt High-priced casting turret, new high-hardness alloy steel, welded car body and other technologies.

Anshan Iron and Steel Science and Technology Department plans to use rare earth elements, alkaline earth metal elements, zirconium, titanium, vanadium, niobium, and boron as microalloying elements commonly used in steel materials. Adding mixed rare earths to ultra-high-strength cast steel can desulfurize, deoxidize, and deoxidize the steel. It makes the sulfide inclusions remaining in the steel into spherical shape, which greatly reduces the harmful effects of inclusions and at the same time greatly improves the impact toughness of ultra-high-strength cast steel. This is a brand new technology. Gaofei only I know the ratio of the ingredients, but I don't know the exact ratio, so I can only try through continuous experiments.Anti-Japanese Blood Sacrifice Mountains and Rivers 918

What surprised Gao Fei was the extremely high cost of this attempt. For example, adding rare earth elements to low-alloy steel and high-alloy steel can produce steel with extremely low sulfur content, effectively control the shape of inclusions, and make each of the steel The performance of the direction is very balanced, especially it can significantly improve the plasticity and toughness of the thickness direction of the extra-thick steel plate. The carbon, silicon, manganese, nickel, chromium, molybdenum and other metals in the latest Anshan Iron and Steel No. 320 experimental armor have the highest hardness in the use state Reaching 350, its hardenability is as high as 62mm. Gao Fei was shocked by the performance of this armor and reached the main armor performance of T[-] in history. Angang No. [-] armor is mainly used for the frontal armor protection of tank casting turrets.

However, the manufacturing cost of Anshan Iron and Steel No. 62 armor is very high. If the monthly output is used to manufacture tanks, only 72 vehicles can be guaranteed. Artillery is a huge problem. The American Pershing tank system design is very good, but Gao Fei still prefers the t[-] and t[-] tank designs. The integrally cast alloy armor turret has very high defense capabilities and will not There is a buffer mechanical part at the rear of the turret, and the low body height increases concealment and reduces the rate of shooting.

The manufacture of about 45 vehicle bodies and turrets per month, coupled with the trial production of the new 3000mm smoothbore gun in Benxi Iron and Steel, and the test firing of new ammunition, kept Gao Fei so busy that he hardly touched the ground. Five armies have already entered the Dingyuan Lake Basin and began to build fortification systems, repair railways, roads and bridges. In order to digest the Far East better and faster, Gao Fei plans to force [-] million immigrants from the government to the northeast, including the Far East. This is It is a very huge project, and people are far from their hometowns. However, the development of the Northeast and the Far East requires human resources, and temporary sacrifices are inevitable.

Gao Fei can choose to produce new tank armor in the United States, but considering the possibility of leaking the alloy composition, Gao Fei intends to provide information to the Americans in exchange for the scientific and technological information he urgently needs in electronics, chemistry, and mechanical engineering. They are willing to provide ready-made equipment rather than information, since it is difficult to guarantee the secret of the new armor once the new tank is put into combat, it is better to take the initiative first.

With regard to the large-scale development of the entire Northeast at this stage, Gao Fei reviewed the resource reports on the three northeastern provinces in detail. Most of these reports came from the exploration and investigation of Japan. Its destructive and plundering mining in other areas of the country shows the Japanese's wolfish ambitions for the three northeastern provinces of our country.

As the most important industrial resources such as iron and steel, aluminum, copper, iron, and coal, Baotou, Ordos, Liaoning, Jilin, and Heilongjiang in Mongolia have a wide distribution of resources. In Shulan, Hunchun, Liaoyuan and other places, the production areas of oil shale are relatively concentrated, mainly distributed in the three basins of Songliao, Huadian and Luozigou. The reserves are equivalent to more than half of the national reserves, and the reserves of non-ferrous metals and non-metallic minerals are large. Many mineral reserves are among the top three, energy minerals occupy an important position, ferrous metals and chemical raw material minerals also have certain reserves.

Gao Fei sent a team of three engineers to build local mines. According to the exploration report, iron ore reserves in Jilin are relatively concentrated, mainly distributed in the eastern mountainous areas, including Laoniugou, Hunjiang Banshigou, and Dunhua Tower in Huadian County. There are several large-scale ore deposits including Tonghua Sifangshan, Helong County Guandi, Tonghua Qidaogou, Hunjiang Dalizi, Qidaogou, Hunjiang Qinggou and other six medium-sized ore deposits, together with Baotou open-pit iron mine and Benxi iron mine, iron resources For Gao Fei, it can fully meet the demand. The mines in the previous Nikken period have resumed production one after another, and the original mining equipment in the United States is also being installed one after another.
