Products Description
The characteristics of ferrosilicon 65 are mainly reflected in its functions as a deoxidizer, purifying molten steel, raising furnace temperature and as an additive of alloying elements. Ferrosilicon 65 contains a certain amount of silicon. During the steelmaking process, ferrosilicon 65 can react with oxygen in molten steel to achieve the effect of deoxidation. Compared with the traditional deoxidation method, this deoxidation method has a better effect and can save the time and labor resources consumed in the deoxidation of steelmaking. At the same time, it can also increase the furnace temperature and the yield of alloy conversion, thus improving the quality of finished steel.
In the process of steelmaking, ferrosilicon 65 can solve the problem of floating oxides on the surface of molten steel. Its elements react with oxides to gather a large number of oxides, which is convenient for filtering and purifying molten steel, thus improving the quality of finished steel. In the cast iron industry, ferrosilicon 65 is used as an inoculant and spheroidizing agent, which can prevent the formation of carbides in iron, promote the precipitation and spheroidization of graphite and improve the properties of cast iron. This is very important for producing high-quality cast iron products.
Ferrosilicon 65 can also be used as an alloying element additive, which is widely used in low-alloy structural steel, spring steel, bearing steel and electrical silicon steel to increase the specific properties of materials. In addition, ferrosilicon is produced by using natural silica as raw material, using metallurgical coke as a reducing agent and adding a certain amount of iron-containing materials for smelting. When using this process to produce 65 ferrosilicon, to ensure the permeability of mineral materials, the granularity of silica and coke particles has specific requirements to ensure product quality and production efficiency.
The low dust removal efficiency is one of the common problems in the dust removal system of ferrosilicon furnaces in the process of making ferrosilicon 65. The reasons for the low dust removal efficiency include improper equipment selection, clogged filter bag, excessive flue gas volume and improper equipment operation. The solutions include selecting suitable dust removal equipment according to the field working conditions, cleaning the filter bag regularly to prevent clogging, reasonably controlling the amount of flue gas and strengthening the training of operators to ensure the correct operation of dust removal equipment.
Excessive discharge from the dust removal system of the ferrosilicon furnace will hurt the environment. The causes of excessive emission include improper operation of equipment, damaged filter bags and incomplete flue gas treatment. Solutions include strengthening equipment operation management, regularly checking filter bags and replacing them in time, and adopting effective flue gas treatment technology.
