Steel and iron smelting machinery


Release time:

Apr 10,2023

Mechanical equipment that uses high-temperature metallurgical methods (also known as pyrometallurgy) to smelt ore or low-purity metals into certain purity metals, or to combine several metals and non-metals to smelt alloys of certain composition. Steel and iron are generally smelted using high-temperature metallurgical methods. Steel smelting machinery includes blast furnaces and their supporting machinery for ironmaking, open hearth and converter furnaces for steelmaking, electric arc furnaces, external refining equipment, ingot casting equipment, and metallurgical vehicles. The blast furnace and its supporting machinery are called blast furnaces, which continuously refine iron ore or artificial rich ore into pig iron. Its appearance resembles a rigid cylinder, composed of refractory materials and metal shells. Figure 1 shows the layout of the blast furnace and its supporting machinery. The raw materials are weighed from the ore storage tank and transported to the top of the furnace by the blast furnace mechanical hopper or belt conveyor, and evenly placed in batches into the furnace. The air preheated by the hot blast furnace is blown into the furnace through the tuyere, causing the fuel to burn and heat the furnace material, decompose and reduce it, thereby obtaining pig iron. The molten iron is discharged from the tapping hole, enters the molten iron tank through the iron ditch and flow nozzle, and is transported to the steel plant or cast into iron blocks by a cast iron machine. The gas exported from the furnace top can be used as fuel after being treated by the gas purification system. To strengthen smelting, in addition to using external combustion hot air furnaces to increase air temperature, increase air volume, or using comprehensive blowing (including fuel injection, oxygen rich blowing, and dehumidification blowing), increasing furnace top pressure can also increase production and reduce coke consumption. The newly built blast furnaces widely use bell valve sealed or bell free high-pressure furnace tops. After adopting the bell free high-pressure furnace top, the height and weight of the furnace top can be correspondingly reduced by about half. The blast furnace has a capacity of about 5500m3 (with a daily output of over 10000 tons of pig iron). The large-scale and continuous production of blast furnaces requires a high degree of mechanization and automation, and it is necessary to use supporting blast furnace machinery such as opening and closing tapping machines and tuyere changing machines.
