2023-3-3: Ferrosilicon is in a stalemate this week. On the one hand, the demand has not improved significantly, and the price of steel bills continues to fall. On the other hand, factories have cut production and overhauled, and the supply has begun to decline. However, the supply and demand structure has not changed, and market inventory also takes time. . The futures market rose last week, but the follow-up was weak. This week, it maintained a slight shock situation. The spot price did not adjust much and fluctuated within a narrow range. At the end of the week, the market price was 72 #7500-7800, 75 #7900-8000 yuan/ton cash natural block ex-factory, 72 # fell slightly, and 75 # rose steadily.

This week, ferrosilicon saw mixed ups and downs. First, the black series was dominated by macro and demand recovery expectations, and the disk continued to rise. Second, due to the impact of the Alashan coal mine accident, coal prices rose. This week, ferrosilicon futures stopped falling and rose, driving spot prices to rise slightly. , Manufacturers' inquiries and transactions have increased. Affected by its own inventory and sluggish demand from magnesium factories, the price of 75 # ferrosilicon fell, and the price difference with 72 # gradually narrowed. In the latter part of the week, the market price was 72 #7600-7800, 75 #7800-8000 yuan/ton, and the cash natural block left the factory. 72 # rose slightly by 50 yuan/ton, and 75 # fell 100-200 yuan/ton.

The price of ferrosilicon raw materials this week: Qinghai and Ningxia silica to the factory price is 200-250 yuan/ton, and there are differences in the price of different factory transportation distances. Shenfu blue charcoal small material 1200-1450 yuan / ton leaves the factory. Shijiazhuang, Hebei 70 # iron oxide sheet 920-950 yuan / ton without tax

Why does some ferrosilicon pulverize?
Ferrosilicon of some components, sometimes due to encountering water or excessive air humidity during storage, and the high content of aluminum, calcium and phosphorus impurities in it, will produce pulverization after a certain period of time, and then emit a foul smell , Toxic phosphine (PH3) and hydrogen sulfide (ASH3) gases, and may even burn in severe cases.
Improper content of aluminum, phosphorus and calcium in ferrosilicon will lead to pulverization of ferrosilicon (as shown in Figure 1). When the content of aluminum and phosphorus increases to a certain value at the same time, this ferrosilicon is easy to dissolve in air with high humidity. Pulverization occurs. Some data point out that the phosphorus content in ferrosilicon is less than 0.04%, and the aluminum content is less than 3%, so it is not easy to produce pulverization.
Some units have observed and studied the silicon content of ferrosilicon and the pulverization phenomenon of ferrosilicon. It is preliminarily believed that the silicon content in ferrosilicon is low (mostly waste products) and it is often easy to pulverize. The reason may be due to ferrosilicon Compounds of silicon and iron such as FeSi and FeSi2 in the medium temperature reduce the volume expansion, resulting in ferrosilicon pulverization. Ferrosilicon containing aluminum will form aluminum hydroxide and gas when it meets water, which is the main reason for ferrosilicon pulverization.
The cooling rate after pouring also has an effect on the pulverization of ferrosilicon. The cooling speed of ferrosilicon is fast, the segregation degree of silicon is small, and it is not easy to produce pulverization; the cooling rate is slow, and the segregation degree of silicon is large, it is easy to produce pulverization. In the same way, if the thickness of ferrosilicon ingot is thicker, it is easy to produce pulverization, and when it is thinner, it is not easy to produce pulverization.

The mainstream market price of ferrosilicon today is 72 #7800-7900CNY , 75 #8250-8300 CNY, 65 #7600-7700 yuan/ton in cash, and the standard block 72 #7900-8000 yuan/ton in cash. The price of bulk supply is lower. Now the company ships Zhongning warehouse 10-50 grain size 03-200; Zhongning warehouse 10-60 grain size 03-230; Zhongwei 03-260; Jiangsu 03+160; Tianjin 03+50. The rhythm of market transactions is still normal, and the wait-and-see mood is strong.

At present, the market performance is tangled. On the supply side, the monthly output of ferrosilicon in January was 515,000 tons, and the demand side is gradually recovering. However, the start time of downstream manufacturers this year is generally later than in previous years. There is no significant change in ferrosilicon raw materials. The prices of silica, semi-coke, and iron oxide sheet are relatively stable. In terms of electricity prices, the electricity prices in the main production areas have been settled in January. Manufacturers in the Zhongwei area of ​​Ningxia reported that the electricity prices rose slightly by 2-3 points, and the off-peak electricity prices were 0.478- Between 0.49 yuan/degree, and the full load is above 5 cents. Inner Mongolia Junzheng's 10 small furnaces are expected to stop production and withdraw from the market in the middle and late ten days, and the affected output will be about 10,000 tons. The furnaces that resumed production in Ningxia from January to February will make up for this part of the output. The import of Australian coal resumes, domestic coal prices are expected to fall, and the drop in coal prices will also drive down the price of semi-coal. In the later stage, it is necessary to pay attention to the trend of coal prices at any time.

In general: the ferrosilicon market pays close attention to the progress of steel recruitment in the short term, and Huabei Hegang will release bidding documents in the near future. From the perspective of expectations, there are both long and short factors, and the futures market trend is relatively tangled.

Ferrosilicon rose and fell in November, and the market price of ferrosilicon stopped falling and rose slightly. The mid-term futures market was stimulated by the Fed’s interest rate hike slowdown and the 16 macroeconomic policies. The futures market rose sharply, driving silicon prices to continue Rising, but in the second half of the year, with the fall of coal price, the price of semi-coke fell, the cost of ferrosilicon fell, and the market price of ferrosilicon fell. The adjustment of the spot price of ferrosilicon is not large. , little changed from October. However, 75 # ferrosilicon was affected by the continuous decline of downstream magnesium ingots, and the price dropped significantly. At the end of the month, the mainstream transaction of 75 # was 8400-8500 yuan/ton, which was 500 yuan/ton lower than that in October.

The use of ferrosilicon
The chemical affinity between silicon and oxygen is very large, so ferrosilicon is used as a deoxidizer (precipitation deoxidation and diffusion deoxidation) in the steelmaking industry. Except for boiling steel and semi-killed steel, the silicon content in steel should not be less than 0.10%. Silicon does not form carbides in steel, but exists as a solid solution in ferrite and austenite. Silicon has a strong effect on improving the strength of solid solution in steel and the deformation hardening rate of cold working, but reduces the toughness and plasticity of steel; it has a moderate effect on hardenability of steel, but can improve the tempering stability and oxidation resistance of steel, so silicon Iron is used as an alloying agent in the steelmaking industry. Silicon also has the characteristics of large specific resistance, poor thermal conductivity and strong magnetic permeability. Steel contains a certain amount of silicon, which can increase the magnetic permeability of steel, reduce hysteresis loss, and reduce eddy current loss. Electrical steel contains 2% to 3% Si, but requires low titanium and boron content. The addition of silicon to cast iron can prevent the formation of carbides and promote the precipitation and spheroidization of graphite. Silicon-magnesium iron is a commonly used spheroidizer. Ferrosilicon containing barium, zirconium, strontium, bismuth, manganese, rare earth, etc. is used as an inoculant in cast iron production. High-silicon ferrosilicon is a reducing agent for the production of low-carbon ferroalloys in the ferroalloy industry. Ferrosilicon powder (particle size

Ferro Silicon Lumps is widely used in steel making and casting. In the steelmaking process, the steel needs to be oxygenated to achieve the ideal high temperature environment, and too much oxygen at a later stage tends to produce more oxides in the steel, which affects the quality of the steel. At the same time, ferro silicon 75 can also effectively promote the fluidity of the steel, improve the absorption rate, reduce the production cost and increase the profit of the steel mill.

Ferro silicon lumps can also be used as an alternative to inoculants in casting to enhance the formation and increase the number of eutectic pellets. The addition of ferro silicon in the production of ductile iron can effectively prevent the formation of carbides in the iron and promote the precipitation and spheroidization of graphite. It can effectively improve the fluidity of the iron, thus preventing clogging of the outlet and reducing the tendency of white mouth of the casting.
