An alloy of iron and silicon. Ferrosilicon is mainly used as a deoxidizer and alloy additive in steelmaking, and is also used in casting, beneficiation, welding rod, light metal industry and as a reducing agent for smelting certain metals. The main raw material of smelting ferrosilicon is silica ore (quartz, silica), SiO2 in the ore is generally higher than 96%, smelting high silicon ferrosilicon is higher than 98%, P2O5 in the ore generally should not exceed 0.02%, Al2O3 should not exceed 1.5%. The commonly used varieties of ferrosilicon contain 45%, 75% and 90% silicon.

Products Description

The raw material of ferrosilicon smelting is high quality combined carbon reducing agent. That is, with metallurgical coke as the main, with gas coal coke, charcoal or bituminous coal as the reducing agent, can make the ferrosilicon product energy saving 200 ~ 300kwh/t. Calculated at 0.4 yuan per 1kwh electricity, annual savings: 158004×200× 0.4 = 12.64 million yuan:

Improve the preparation technology of ore in furnace. To ensure that the charge has a suitable block degree to ensure good gas permeability, to obtain a better smelting index. At present, the natural power factor of mineral furnace equipment is generally low, and most of the mineral furnace smelting process has a natural power factor between 0.5 and O.7. In order to improve the natural power factor of mineral furnace, reactive power compensation installation is required. At present, the more mature compensation method is to connect large capacity ultra-low voltage and high current power capacitor banks into the secondary side of the furnace transformer with corresponding automatic control and specific short network connection mode for reactive power compensation. Through the corresponding compensation, the reactive current consumption of the short-circuit network, the transformer of the ore furnace and the power supply network is reduced.

When ferrosilicon is smelt in different capacity of ore furnace, there are differences in the electric heating conversion rules in ore furnace, the smelting process operation system of different furnace types is not the same, and the raw material conditions in different regions are also subtle differences, which will cause great changes in the smelting characteristics of ore furnace, and some smelting characteristics parameters are difficult to measure accurately. In order to further understand the changing law of the smelting characteristics of the ore furnace, it is necessary to combine the actual production situation of the factory, through statistics of a large number of actual production data, summarize its internal rules, and simulate the approximate value.

An enterprise in Inner Mongolia has built 12500kVA ferrosilicon thermal furnace, 25000kVA ferrosilicon thermal furnace, 36000kVA, 81000kVA ferrosilicon thermal furnace for production. Through the long-term data analysis of nearly two decades, with the increase of furnace type, its thermal efficiency also increases in different ranges. When the 81000kVA ore furnace is selected, the maximum increase in thermal efficiency is 10%.

In addition, the mineral heat furnace with a capacity of 81000kVA is adopted, which has stable furnace temperature, stable operation, uniform product quality and reduced smelting power consumption. At the same time, the increase of furnace capacity creates conditions for the mechanization and automatic control of raw material transportation and operation, improves labor productivity and reduces operating costs.
