Huazhong Iron and Steel Company (Daye Steel Plant)
On May 15, 1949, Huangshi, Hubei was liberated. On May 27, Wuhan Military Control Commission took over Huazhong Iron and Steel Company (Daye Steel Plant); on June 13, it was named Wuhan Military Control Commission Huazhong Iron and Steel Company; on September 1, it was named It is Huazhong Iron and Steel Company of the Central Plains Provisional People's Government; in October, it is under the leadership of the Ministry of Industry of the Central Plains Provisional People's Government.
During the Anti-Japanese War, most of the equipment of the enterprise was demolished to Chongqing, and the rest of the equipment was damaged. After the victory of the Anti-Japanese War in 1945, the Nationalist government built a 66-cubic-meter blast furnace, a 1.5-ton converter, and 250mm and 430mm rolling mills, but none of them were completed and put into operation; after taking over, they resumed construction and completed the converter project and 250mm rolling mill. In December 1949, at the first national iron and steel conference, the scale of its original production capacity of 10,000 tons/year was expanded to 30,000 tons/year. In order to meet the needs of resumption of production and development, the company has set up corresponding management institutions, namely Room 1 (Technical Room), Plant 4 (Iron-making Plant, Steel-making Plant, Rolling Plant, Machinery Plant), Division 4 (Manager's Office, Administrative Office) In 1950, a 15-ton open-hearth hearth and a 430-mm rolling mill were built. In November 1950, the Korean War broke out and threatened the security of Northeast my country. The central government ordered the Dalian Steel Plant to be relocated to Huazhong Iron and Steel Company, and the Huazhong Iron and Steel Company Special Steel Plant was established. 1 set of 6-ton electric furnace, 1 set of 500mm steel rolling mill (main motor and electrical equipment), 1 set of 300mm steel rolling mill, 2 sets of 2-ton forging hammers, 3 sets of 1-ton forging hammers, 1 set of 0.5-ton forging hammers, 15 1 ton crane, etc. More than 670 cadres, engineering technicians and workers of Dalian Steel Plant were also incorporated into Huagang. At the end of 1952, the equipment for the southward relocation of Dalian Steel Plant was basically installed in Daye Steel Plant and put into production successively. By 1953, the main production equipment of Daye Steel Plant included one small iron-making furnace of 70 cubic meters, one 15-ton open-hearth furnace, two 1.5-ton converter furnaces, one 1.5-ton, 3-ton and 6-ton electric furnaces, and small rolling mills. 2 groups, 7 sets of steam hammers ranging from 0.5 tons to 2 tons; the annual output is 23,000 tons of pig iron, 48,000 tons of steel ingots, and about 40,000 tons of rolled steel and forged steel (including 6,800 tons of forged materials).
