In the early 1980 s, the second detachment was responsible for the construction of the 1150 primary rolling mill of Benxi Iron and Steel Company, and the third detachment was responsible for the construction of the 1700 hot continuous rolling unit. The metallurgical unit of the infrastructure engineering corps has made outstanding achievements for the country's iron and steel industry. Recently, the "Home of comrades in arms of infrastructure engineering soldiers" has forwarded articles of comrades in arms several times, recalling the magnificent history of the metallurgical troops in the battle of Benshan Iron and Steel Co., Ltd. Some comrades in arms are not very clear about 1150 and 1700, and some people mistake it for an engineering code. I am studying metallurgical equipment, and I would like to give you a simple introduction to the popularization. Interested comrades can refer to it. Metallurgical equipment is mainly divided into three categories: ironmaking equipment, steelmaking equipment and rolling equipment. Ironmaking equipment is the most important blast furnace. For example, the 1513 ironmaking blast furnace built by our second team in Jiayuguan Jiugang. 1513 represents the internal volume of this blast furnace is 1513 cubic meters. Steelmaking equipment is the most important converter (50 s is mainly the flat furnace, special steel is generally smelted by electric furnace). For example, the current relatively large 300-ton converter means that this furnace can smelt 300 tons of molten steel at a time (theoretical data).
