Description

Technical Field

[0001] The utility model relates to the technical field of charging materials in submerged arc furnaces, in particular to a fully automatic hydraulically driven charging device. Background Art

[0002] Ferroalloys are essential raw materials for the steel industry, and are mainly used as deoxidizers and alloy additives for steelmaking. At present, most of the ferroalloys on the market are produced by continuous operation of charging in a submerged arc furnace (also known as a reduction furnace) and tapping iron and slag intermittently. When charging, the better the permeability of the charge, the more uniform the conductivity, the lower the energy consumption, and the better the product quality. On the contrary, during the charging process, if the charge is uneven, the charge resistance will be unstable, causing the electrode to fluctuate up and down, causing the collapse area to move up; if the charge is too thick, its permeability will be destroyed, because in this case, the gas emitted cannot overcome the resistance of the thicker material layer, causing uneven emission and forming the so-called piercing fire. In this case, most of the current is connected through the upper material layer, the reaction zone is transferred to the upper part, and the electrode will leave the bottom of the furnace, resulting in a dead material area at the bottom of the furnace, and the bottom of the furnace rises, making it difficult to tap the furnace. Therefore, a reasonable charging method is extremely important for ferroalloy production.

[0003] There are three traditional ways of charging, namely manual charging, charging by charging trucks and semi-automatic chute charging. Manual charging involves manually delivering the charge to the reaction zone, which has the advantage of uniform distribution, but has the disadvantages of potential safety hazards, high labor intensity, low production efficiency, flue gas and dust spillage, and serious environmental pollution. The charging method with charging trucks involves delivering the charge to the reaction zone by charging trucks, which greatly reduces manpower, but is prone to mechanical failures, uneven distribution, and environmental pollution. The semi-automatic chute charging method involves controlling the charging of the charge to the furnace through the silo through the material pipe and chute. Compared with the previous two methods, this method has uniform distribution and a higher degree of automation. However, during the charging process, since the chutes are mostly fixed, the position of the chute outlet is fixed, and the disadvantage of uneven charging is still prone to occur during the charging process.
